CSC Fitting Practice
To avoid premature failure (usually leakage) from the CSC, some basic instructions must be followed whilst handling / fitting a new Concentric Slave Cylinder.
1. Handling of new product
On removing the CSC from the packaging, do not compress the cylinder by hand to replicate the bearing movement. Some CSC’s are pre-charged with oil and manually compressing the CSC can cause damage to the internal hydraulic seal by introducing air into the CSC. Alternatively, some CSC’s may not be pre-charged with oil and manually compressing the CSC will cause the same damage by introducing air into the CSC.
By compressing the cylinder in this way, the increased air pressure can cause the damage illustrated in the image. Further damage can occur to the internal seals due to excessive friction on the return stroke when manually depressing the CSC.
2. Fitting environment
The CSC has not seated squarely, and hydraulic pressure has forced the back plate out of position
New CSC – no damage to the back face plate
The area in which the CSC is positioned needs to be totally clean & free of debris. It must locate cleanly and squarely onto the gearbox case, and any rubber face seal or sealant is only used if the vehicle manufacturer’s instructions recommend it.
If the CSC is not seated correctly, the back face can push out as below, which will cause it to leak and fail and is not covered by warranty.
3. Fitting
Gently slide the CSC over the gearbox input shaft and slightly rotate it to ensure the correct location on the gearbox case.
Ensure the mounting surface is clean and free from any debris.
No sealant should be used on the mounting surface.
Torque down the mounting bolts evenly to the manufacturer’s torque specification.
4. Hydraulic Connections
There are two types of connectors:
• Traditional screw in
• Quick clip connector which is more common. With the traditional type, tighten the screw to the manufacturer’s specification.
The quick clip connecter can be released by either pulling or pushing the retaining clip, dependent upon the type.
5. Bleeding (Purging) the system
Before attempting to bleed/purge or operate the clutch, ensure that the gearbox is fully located in the fitting position.
Tighten a few securing bolts to prevent any movement. This will avoid the unit from being over-stroked causing damage to the chamber seal.
Flush the hydraulic system to ensure all contaminants and old sediment is removed from the system. Failure to flush the system may contaminate the new CSC and cause premature failure of the CSC which is not covered by the warranty.
Bleed the system as per the vehicle’s manufacturer’s instructions.
Always use the correct hydraulic fluid as specified by the vehicle’s manufacturer.
Only use a pressure bleeding device if recommended by the vehicle manufacturer.
PLEASE NOTE: Clutch Industries does not recommend the use of power bleeding systems, as some systems run high air pressure. This can invert or roll the internal seal resulting in immediate fluid loss
Troubleshooting
Unable to select gears and no pedal (due to CSC failure). (See Image 1)
The distortion to the retaining ring is a result of the bearing exceeding its maximum travel.
The distorted retainer indicates that the bearing has been forced against the ring during the bleeding process. (See Images 2&3)
This also damages the piston's internal seal resulting in the loss of fluid past the seal.
Over-stroking during the bleeding process is the result of the clutch pedal being pumped rapidly, which doesn’t allow the cylinder to return to rest before the next pump stroke.
The Solution
To avoid the cylinder being over-stroked, the pedal should be depressed and then released slowly to allow the cylinder to return to rest before the pedal is depressed again.
In some cases, the bleed nipple/pipe may need to be locked off after every downward stroke of the pedal, until some pressure in the system is achieved.
This process may need to be conducted numerous times before some pressure is felt in the pedal.
This is a common action required when bleeding the system, as an airlock can occur within the clutch master cylinder.
A wheel bearing is an important component of the wheel assembly that connects the wheel and axle. It allows the wheel to rotate smoothly and with minimal friction. Wheel bearings are safety-critical components that are designed to withstand radial and axial loads caused by gravitation, acceleration, braking, and cornering forces, so they must be replaced when they fail.
A bad wheel bearing symptoms include:
A humming, rumbling, or growling sound that becomes louder as the vehicle accelerates or turns.
When the vehicle is moving, there is a loud constant whining or grinding noise.
When driving over uneven road surfaces, you may hear clunks.
Looseness, excessive steering wheel play (vague steering);
Vibration in the steering wheel that changes with vehicle speed or as the vehicle turns;
ABS isn't working properly. Failure of the ABS sensor integrated in the wheel end bearing can cause ABS system issues.
It is best to avoid driving for any length of time with a worn wheel bearing, any weakness in this connection could have serious consequences for your drive-axle and steering assembly - as well as your safety.
What causes wheel bearings to fail?
I. Inferior tools, such as a hammer or an impact wrench, can damage the exterior and/or interior of the wheel end bearing, causing it to fail prematurely. Furthermore, reusing old accessories such as bolts, nuts, circlips, split pins, seals, etc. instead of replacing them can cause the wheel end bearing to operate under abnormal or unsafe conditions, increasing wheel end bearing wear and the risk of a car accident.
II. Driving through a pothole, driving over speed bumps, or hitting the gutters, can damage and shorten the life of a wheel bearing.
III. Driving conditions can cause your wheel bearings to fail if you drive through deep water or mud. Water, mud, or other contaminants such as dust or road salt may pass through the seals and enter the bearing, polluting the grease and causing the bearings to wear out.
IV. Poor heat treatment can result in premature wear and failure of wheel bearings made of low-quality materials.
V. Car modifications, such as larger or wider rims, tyres with lower thread walls, stiffer shock absorbers, and suspension springs, increase the load on the wheel bearing and can speed up wear. Stick to the rims, tires, shock absorbers, and springs recommended by the manufacturer to reduce the impact on longevity.
Despite the fact that modern wheel bearings are easier to install than previous generations, proper installation, the use of appropriate tools, and adherence to the torque values specified are still required for maximum performance, durability, and safety. As a result, we recommend having your wheel bearings replaced by a professional mechanic who has the necessary skills and tools. It is critical to use high-quality parts when replacing your wheel bearings.
Radiator Leak Prevention
Radiator leaks can occur at any time, which is why it is critical to understand how to avoid radiator leaks in your vehicle. Car engines get extremely heated. This is due to the fact that an automobile's engine is powered by explosions. Even in a single minute, thousands of explosions occur only to keep your engine going and the wheels rolling. As a result, heat is produced as long as the engine is operating, and it is critical that every automotive engine be kept at the proper temperature. It should not be so cold that the engine struggles to run properly, but it should also not be so hot that it damages the engine.
What Is the Radiator's Purpose?
The radiator is the cooling system of your vehicle. Its primary function is to prevent your car's engine from overheating. This is accomplished by directing heat away from the engine and into the radiator, where it is dissipated into the air.
The radiator circulates coolant throughout the engine via hoses and tubes. The coolant can now be heated. The coolant then returns to the radiator, releasing heat and cooling the radiator fluid so that it may be heated again.
The radiator's role is to absorb heated fluid from the engine, cool it by releasing the heat into the air, and therefore cool the engine, rinse and repeat. It is critical that the radiator continue to function while the engine is operating. That is why keeping your radiator in good working order should be one of your top concerns.
Radiator Leaks: What Causes Them?
The radiator is both fluid and metal. On the interior, it looks more like a plumbing system than a monolithic cooling unit. From this, you can understand why leaks can cause so much damage and mean the end of your radiator.
However, the cause of your radiator leaks could be one of several factors, and it could even be multiple factors at the same time. Rust is the most common cause of corrosion. The cooling fluid is not like water, which causes corrosion. Most coolants are even intended to prevent or slow down corrosion. However, as the coolant degrades chemically due to wear and tear, specifically the glycol breaks down and the pH level drops, it begins to cause corrosion in the system.
Having low-quality coolant is one of the causes of radiator leaks. The other cause is associated with rust and other sediments that collect over time. This creates holes in the hoses, allowing coolant to flow out.
Maintain And Replace Your Radiator Coolant On A Regular Basis
To prevent radiator leaks, it is critical to properly schedule and follow through on radiator coolant maintenance and replacement.
Radiator coolant will degrade due to wear and use. As a result, the radiator coolant must be replenished every 24 to 36 months of regular use. This ensures that the fluid traveling through your car's radiator system is effectively cooling your engine and preventing overheating.
Get A High-Quality Coolant
It's also critical that when you replenish your radiator coolant, you don't just pour anything labeled "coolant" in there without thinking.
All coolants are not made equal. Investing in a higher-quality coolant will help your radiator operate better, live longer, prevent rust, and last longer. As a result, the lifespan of your car engine and vehicle can be extended.
To Prevent Sediment And Rust Buildup, Flush The Radiator
When replacing the radiator coolant, make sure to flush out any silt, debris, or rust particles that may have gotten into the system. It is critical to flush it out with distilled water (to ensure that no minerals contribute to the buildup) to ensure that the hoses and tubes of the system are filled with only what is supposed to be there - the coolant.
