Author: In Mercedes 126 Repair: Forgotten Fluids, Part I we looked at the rear differential. Now let’s turn our attention to another fluid that most owners never bother to change — power steering fluid.
POWER STEERING FLUID CHANGE
Most Mercedes 126 owners will never take apart their recirculating-ball steering gear box. But those that do gain a new-found appreciation for the importance of clean fluid in the power-steering system. In addition to the main worm gear assembly and the interface between the ball nut and the sector gear that actually turns the Pitman arm, there are several sets of needle bearings. All these moving parts are lubricated by steady flows of power steering fluid. The more heavily contaminated that fluid is, the more rapidly these parts will wear. And a worn steering box translates into sloppy steering, potential safety hazards, and an expensive repair or replacement. (The power steering pump, by contrast, is much, much easier to replace, and good used units can be sourced for as little as $50.)
There has been some debate about the propriety of using automatic transmission fluid (ATF) in this system. While ATF was specified in the owners manual, ATF is not what it used to be and has become somewhat hostile to the many seals within the steering system. Ideally, ATF should be eschewed in favor of plain old power steering fluid. While synthetic fluids are available, conventional fluids are perfectly fine.
To change the fluid, support the front of the car on jack stands so that both front wheels are off the ground. Undo the hose clamp securing the return hose to the return “snorkel” screwed into the pump, and direct the hose into a suitable container for catching the old fluid. Either plug the snorkel or loosen it with a 19mm wrench and turn it so that it points upwards, allowing you to fill the reservoir without losing fluid from the return fitting. The standard procedure here is to start the engine and add fluid while the pump quickly forces the old fluid out. But this procedure has some major disadvantages. It is most emphatically not a one-man operation. The flow rate is so fast that there is a great risk of the pump running dry and sucking air unless a steady supply of new fluid is poured in. If things get out of hand, you need a helper to shut the engine off right away. If you don’t have a helper and don’t want to risk damaging the pump or pulling air into the system, you need a better way.
Fortunately, it is perfectly possible to pump out the old fluid in a highly controlled fashion simply by turning the steering wheel from stop to stop. Keep the fluid level in the reservoir above the filter to prevent the ingress of air, and continue until you are satisfied that the fluid leaving the system through the return hose is clean. You need 2-3 quarts to fully replenish the fluid, though if you’re trying to remove all traces of (red) ATF you may find it takes a little more to end up with a completely clean reservoir. When you’re happy, reconnect the return hose and thoroughly bleed the system by turning the steering wheel back and forth with the engine running.
This is, of course, the perfect opportunity to change the filter in the pump and inspect the rubber return hoses, replacing if necessary. The fact that Mercedes gave us a filter in the power steering pump tells us something about the importance of clean fluid. How many other car manufacturers do this?
We’ve now looked at two “forgotten fluids.” Are there any others? Well, of course there are! Continue reading this series for more maintenance tips for your Mercedes 126.

The most crucial aspect to safely riding a motorcycle, of course, is learning how to properly handle one. Once you have the basics down, it is simply a matter of gaining more experience over time and learning how to negotiate more complex traffic scenarios. However, if you don’t regularly service your motorcycle, no amount of driving skills or experience may save you from a serious accident. One of the greatest threats to proper handling for even the most experienced of drivers is a steering problem or handling defect. When a rider is not able to steer the bike properly, a severe crash may result.
The Importance of Regular Maintenance
An infrequently or improperly serviced bike is a dangerous bike. In many cases, handling defects develop gradually over time so you may not notice a growing problem until it is too late. To minimize your risk of an accident caused by poor handling, have your bike serviced by an experienced professional trained to look for warning signs of a steering problem. You could also take a maintenance class or learn the details from a friend to service your own bike. Whichever you decide, be sure to check all aspects of your handling each time you perform bike maintenance, including:
- Steering alignment
- Handlebar position and condition
- Steering head condition
Maintaining Your Steering Head Bearings
One of the most important parts of a functional handling system is not visible from the outside of the bike. Motorcycle steering relies on bearings located inside the steering head, which are lubricated to provide for smooth steering. Over time, the grease on the bearings will dry out or be washed out by power washes and rain. When the bearings are not properly greased the handling will become more shaky and unreliable. The bearings can even become damaged, possibly causing the rider to lose control altogether. Because the grease on the bearings wears off slowly over time, you may not realize that your handling is gradually becoming more and more difficult. Keeping your bearings lubricated at all times can help you avoid a potentially severe accident.
If you have properly maintained your bike but still experience handling problems that result in a crash, you may be the victim of a handling defect. Your motorcycle manufacturer may be liable for a defective part, poor design, or improper installation. Likewise, a mechanic may have incorrectly maintained your bike and may be responsible for a handling problem that caused your accident. If you have experienced an accident caused by handling failure, consider contacting a motorcycle accident attorney immediately to investigate the details of your case.

The process of payment reconciliation is complex, yet vitally important since the health care provider is the only party with access to both the billing system and the bank account. A discrepancy between the records could be symptomatic of a delay between various events, faulty deposit process, or fraud.
The multitude of steps that occur on varying dates complicate reconciliation process, as they affect how and when money is received, deposited the bank account, and recorded in the billing system:
- Office:
- Cash is collected in the office
- Explanation of Benefits (EOBs) are received in office
- Cash is recorded in the billing system
- EOBs are entered in the billing system (may have different check date than EOB date created in the billing system or bank deposit date)
- Electronic Remittance Advice (ERAs) are recorded in the billing system (may have different check date than ERA date created in the billing system or EFT date)
- Cash that was collected in the office is deposited in the bank
- Checks received from insurance company are deposited in the bank
- Electronic Fund Transfers are deposited in the bank
For example, you may receive an explanation of benefits and a check on February 28. Suppose you fax them both to the billing system on March 1. Although the check is dated February 28, it will not be entered in the billing system until March 1 at the earliest, causing that check to show up on your March invoice. Conversely, the delay between the ERA date and the actual bank deposit date may take a week or longer. the billing system may receive ERA notice of payment from the insurance company on May 27, but payment would not appear in your bank account until June 2, causing a similar discrepancy between collections and invoice in May and June.

The power steering pump is a mechanism applied in many vehicles to help the van’s controller to manage the car while in motion. Power steering is meant to help the person controlling the van by deploying some power to a part of the engine especially when negotiating bends, corners and/or turns, sharp or not sharp. The steering pump contains many fundamentals that help the driver to feel and experience a smooth drive. Such items mounted on this part of the car engine include; fluids cover plates for suction passage, and discharge purposes; a rotor which is located in the cam chamber and has vanes which can be slid.
Many companies manufacturing vehicles have changed into a more manual means of controlling the car. Many cars that rely on the front wheel drive are being produced. This has made the cars to be heavier and hence the need implement manual drive. Therefore, creation of the power assisted cars. There are two types of this mechanism. The system can either be an electronic system or a hydraulic one; though some companies also manufacture cars in-built with a combination of the two.
In the hydraulic systems, the car engine is supported by the steering pump when the van is moving and/or trying to shift direction from one and to another end. The assist only comes when the driver is trying to turn the steer wheel during a turn. When the two are compared and contrasted, one will find that electric option is more efficient than the other one. This is because in the electric system, the electric motor needs only to supply help or support when the wheel is turned while in the hydraulic mechanism, the drain must keep on running. Since there is use of hydraulic power fluid, it therefore causes environmental and health hazard from the leakage. This makes the electronic system a better choice for pollution free societies.
For a vehicle to move from one point to another, it must be controlled or driven. The engine of the car is what applies all the mechanism it needs in order for it to move. The power steering pump is one of the elements of the engine in most cars. It is attached on the engine using belts and winches.
The hydraulic system is the most commonly used. The steering pump as implemented here has a fin-like item that is used to guide the hydraulic fluid through the main passages. It therefore must be able to regulate the pressure by increasing or reducing the pressure and force depending on the status of the car at the moment. At a resting position, the system produces a lot of pressure than when in motion. This is because the van’s speed monitors the pressure produced. That is, the higher the speed the more the production of fluid. This employs the use of a rotary control device which is present on the power steering pump for the purpose of detecting the force applied on the wheels.

Your exhaust system may consist of a manifold, and a series of pipes, muffler(s), catalytic converter and exhaust tip, all designed to scavenge the hot exhaust gases from your engine out to the open air.
Many of these parts will need replacement over the life of your car. There are a variety of aftermarket companies that manufacture some or all of these components as replacement parts.
One of the most confusing seems to be the term cat-back system. It is actually a very straight forward idea, but the name may not be understood. As part of the exhaust system in most cars in America is a special device called a catalytic converter. This device is designed to remove harmful chemicals in the exhaust steam, buy converting them to other less harmful products. The catalytic converter or cat is required in all 50 states, and it is illegal to drive a car without one.
So the term cat-back refers to all parts of the exhaust system between the outlet of the catalytic converter or cat and the outside air. This usually means a series of pipes, one or more mufflers, and perhaps exhaust tips.
When you have to replace your cat-back system you have many choices. The simplest is to go to a new car dealer and buy the exact same equipment that came with your car. This is fine for most drivers. However, there are some people who are looking for something beyond the stock system.
They may be interested in more power, a deeper sound, a longer lasting system or something that has more eye appeal. You can find combinations of these or systems that offer all of these attributes.
The best cat-back systems are made with stainless steel and have a lifetime warranty. In this category you can find systems with less restrictive mufflers. These mufflers will regain some lost horsepower that the stock muffler took, because of its internal design and the backpressure it developed. Some are called “glasspacks” and others are “straight through” designs. You can also find systems that lower the sound frequency and give you a deep sound that is not normally found on the typical four or six cylinder engine. And of course you can find systems that have a giant tail pipe tip. It looks impressive, but for practical terms does not do much for your car.
Shop around and look for brands that offer some or all of these features. Keep with the name brands and you will not go wrong.

To make a go kart that corners on rails like a Porche, looks like a Ferrari and turns all your neighbor’s heads we need to back up the truck and go to the beginnings.
In short hand, there are five steps to making a simple frame. First of all the following steps are:
1. Engine And Passenger Layout
2. Drive Train System
3. Steering System
4. Brake System
5. Throttle System
Let’s get into it now….
1. Engine And Passenger Layout
First of all the assumption, whether this go-kart is made out of wood or is made out of steel is that you have some sort of layout in mind. Typically the engine is behind, and the person sits in front of the engine. A good safe layout is to have a seat protect the passenger from the engine.
So a structure of some sort is needed to hold the seat in place. You can use a seat off of a chair, but a more protective seat is a ½ piece of plywood angled back and supported. Covering the piece of wood is optional, but it is more comfortable with basically a piece of heavy cloth covering a cushion. The cloth is stapled typically into the board (on the backside).
The structure supporting the seat can be wood, or steel.
The frame work can be wood or steel as well. If using wood, use two by fours placed vertically, so that the strength of the wood is optimized.
If you are using steel for the frame, use a tubing that is at least .070 wall or thicker. The length of the frame is really dictated by how big the person is. Have a person sit comfortably in the leaned back position with a steering wheel in their hands. That is the person compartment. Measure this length.
Add the engine drive section and the person compartment lengths together and that is the length of the gokart. Cut your frame tubes (or tack tubes together) to this length. You will need at least two parallel lengths of tubing.
Space the tubes apart the width of the seat you made (20 inches is a good width).
Cut at least four (4) tubes to the 20 inch length. Lay all the pieces on the floor. Place the 20 inchers at the following locations: Engine Plate area, seat back section, seat forward section, front main bumper tube, and rear main bumper tube. (The bumper tubes can be wider than the frame by 12 inches (6 inches per side).)
Tack the tubes in place using a welder. If you do not have a welder, then you can fasten them together using plates and bolts. (Trust me, buy a $100 welder and save yourself wood chips and drill bits, busted knuckles and exasperation!)
What you have put together now is what I term a “flat-go kart.” You will soon find out that flat gokart frames are weak and require extra stiffening. You may want to put some struts into the system to bolster the frame design. Typically what I use is the seat back as reference. This works very well as an integral frame support, side seat holder, and engine protector.
2. Drive Train System
The next sequence is to place your engine and drive train system in place. At the same time put your seat in position to make sure the seat and engine are not hitting each other. Be sure to make the seat removable so that you can actually work on the engine system when needed.
When placing your engine typically a plate is needed to hold the engine onto the frame. Some designers use tubes with holes drilled in them for engine placement. I prefer the plate option, because it gives me greater options as far as engine choices in the future.
For example on the Phi-Alpha-10 and the Phi-Alpha-9 (go karts I designed) the engine plate served well in allowing me to use different engines, whether Briggs and Stratton, Tecumseh or even Honda. All engine types could be easily mounted just by drilling the holes in the motor mount plate.
Most go karts use a slot system to keep the chain tight. In other words, the engine is mounted not using holes but slots. That works, but honestly, drilling slots is intensive works and requires some patience and thought. So I prefer tensioning the chain, it works better on multiple fronts. (I can go on and on about engines, drive trains and such…but we have got to keep moving here…)
A word about drive systems: A live axle system is really the way to go. All you have to do is mount two bearing brackets and away you go. On a one wheel drive system, you need to have special rims that contain bearings, special drive sprockets that connect to the tires, and the axle if it gets bent, you have to cut it out of the frame and start over….so use a live axle…
But, that is not all true. You can get away with using old lawnmower wheels if they have bushings in them. They work great for acting as bearings. Grease snot out of the axel-hub interface and away you go. Be sure to retain the wheel with a cross bolt that is at least grade 5.
3. Steering System
So after having mounted the rear axle (with brake disc (or brake drum) and sprocket), and having placed the engine and chain system in place, proceed to mounting the front steering system.
Before we did some measurements of the person sitting in the comfortable position, make sure you remember the measurement (relative to the go kart frame) of the steering wheel. That is the target point for the steering wheel.
The actual position of the front wheels is a bit more involved though. You will need a scale. Place the scale first of all under the rear wheels. I typically use a board placed across the rear frame rails underneath the wheel area. Have someone sit in the go kart. (Be sure to a have the front wheels, steering wheel and steering structure on the go kart when you weigh it)
Now proceed to the front of the go kart and place the board in the general area that you want the steering system. Again weigh the go kart.
Take the two weights and add them together. That is the total weight. The front weight ideally should be with-in 5 to ten pounds of the rear weight. This is called 50/50 weight distribution. The more weight you have on the rear, the more the go kart will under-steer. Meaning, when you turn the wheel the go kart will tend to keep going straight. The more weight you have on the front wheels, the more the go kart will over steer. Most drivers are used to under-steer, it is easier to recover from.
But I digress…
Once you have placed the front wheels in place then fix the front steering system in place there. I typically use plates, so that I can move the steering system back or forward. So I weld mating plates on the frame and the steering system, then bolt them together.
For wood go karts, you can actually design a very stable wood go kart using the carriage style steering as long as the steering is supported an not aloud to twist.
A word on steering systems: You can purchase from the store steering assemblies that you tack onto tubes. These work real well, with one exception, they typically come in .750 inch diameter shafts, where most high speed bearings use .625 diameter shafts. The shafts may need replacement. Look for .625 shafts… Additionally, there are ways to make the steering more tractable and more user friendly, these involve geometric relationships such as camber, caster, Ackerman and so forth.
4. Brake System
Now that you have the steering system in position, you can button up the hole project by covering the bottom of the go kart. Sheet metal (like furnace guys use) is the best option. Buy some tech screws (the ones with drills on their ends) and zip through the sheet metal into the tubing. Once you have that in place, you don’t have to worry about your feet hitting the ground!
Now it is time to place the brake system. You notice we placed the brakes in place on the live axle, now the actual braking mechanism needs to be mounted to the frame work. You can either weld it, or bolt it to the frame. I prefer bolting, it is more forgiving and easier to repair.
A word on brake float: The brake system should float. What that means is that the disc either needs to be mounted freely on the shaft, or the brake caliper needs to float. If the neither is floating, you will get a binding, and prematurely worn out brakes, and fast! So keep that in mind. Something has to float, the disc or the brake caliper (1 of the 5!)
For your brakes it is important to have the brake off while driving. A good spring is needed to keep the pedal back when the brake is not being used.
On a wood go kart be sure to use the same thought into the brake system. A lot of force is going into the brake boards so be sure to account for this in the brake mechanism which usually involves force multiplier linkages.
5. Throttle System
This seems like the most inane or over looked system on the go kart. It shouldn’t be though. A good connection between the throttle and the pedal is needed and a good range of motion is needed too. Most pedals give you different holes to work with, allowing your several options in throttle actuation.
Again, like the brake, a good spring is needed. Do not use a spring on the carburetor, but use the spring in the pedal, or pedal system.
A word about throttles: most engines come with governors. It is a good idea to use the governor system, because it helps keep the engine at even speeds and from over revving.
