The transmission system on a commercial vehicle is highly engineered to make sure that it can put up with the stresses and strains of everyday life. When such a vehicle is used in a congested city environment, the driver will need to change gear on an almost constant basis, and it is, therefore, very important to ensure that the clutch system can cope. If you're currently dealing with a clutch-related issue on your heavy truck and cannot pinpoint the problem, why should you look more closely at the master cylinder?
Master Cylinder Control
On a vehicle fitted with a hydraulically activated clutch mechanism, the master cylinder is critical. This component helps to store the hydraulic fluid and to deploy it each time the driver pushes the clutch pedal. While the cylinder is fitted with heavy-duty parts, they will nevertheless wear down with time and will be especially vulnerable to heat damage during slow movement. This may cause the seals or O-rings to degrade, and this will eventually lead to a fluid leak.
Drag and Slip
If the master cylinder is faulty, this could result in clutch drag. This issue will make it very difficult for the driver to select the correct gear due to an inadequate amount of pressure in the system. The fluid may be contaminated due to excess heat over time, and this could cause a blockage within the central port of the master cylinder. When this happens, the clutch mechanism may slip, and even though the engine will be working hard, the vehicle will not move forward correctly.
Eventually, the entire mechanism will begin to fail as the master cylinder will not be able to provide the right amount of pressure to operate the key parts. When the clutch pedal is depressed, the fluid will leak even more, and the release fork may not engage correctly.
Having a Closer Look
Have a look at the fluid level within the master cylinder reservoir. Check underneath the reservoir casing to look for any signs of a leak. If you depress the clutch pedal and notice that the fluid within the reservoir rises, this is another sign that the part is faulty and may need to be replaced.
If you feel that you need to change the master cylinder, make sure that you only get the best quality parts available. Use hydraulic fluid that has been designed and tested on your particular make and model of vehicle as well, to help with future performance.
