General Clutch Kit FAQ’s

Yes this is normal when using some of our clutch & flywheel packages. With some clutch pedal adjustment fine tuning you can get this in a suitable position.

It is important with any adjustments made to get under the car and confirm that the clutch fork can be pushed back to compress the slave cylinder. If so, then you have hydraulic clearance, and this is OK. If the slave cylinder cannot be compressed then the system is holding constant pressure against the clutch and will need to be backed off at the clutch pedal to correct it.

Typically a squealing / squeaking noise that is apparent when your foot is off the clutch pedal but goes away when pressure is applied is a sign of a dry pivot & fork.

When the pivot & fork are lacking lubrication it can resemble and is quite commonly mistaken for a bearing noise. A release bearing will usually become noisy when applying pressure to operate the clutch.

The life expectancy of a clutch is determined by many different factors.
e.g – What the vehicle is used for, Quality of installation, and the biggest factor being the driver in control.

When experiencing clutch slip you may notice that the RPM is climbing while not gaining the usual vehicle momentum. You will feel poor acceleration and it may sound like the engine is labouring.

There can be many causes behind clutch shudder ranging from worn driveline mounts, extreme heat through the clutch components & contaminated friction materials. Contamination on the friction material can come from either an oil leak or even lack of preparation during the installation process. In some cases extreme heat through the clutch components plays a role. This can be caused by clutch slip or excessive riding of the clutch.

The spring washer goes to the top, then the two flat washers underneath. (we may need a photo of this)

When installing an aftermarket heavy duty clutch, there is a noise than can occur that is noticeable when operating the clutch above 1700rpm. This noise is not causing any damage, it is simply something that can occur in some vehicle when going away from the factory genuine clutch. Not all vehicles will make this noise, and the vehicles that do can vary in how loud or quiet they are.

FAQ's - Patrol TD42

We recommend using the hydraulic combination of GU master cylinder & GQ slave cylinder to achieve correct clutch operation GU master cyl part # JB9575 – 11/16” bore size GQ slave cyl part #JB4198 – ¾” bore size.

If you have a bad squealing noise that gets worse when applying pressure there is a good chance that the release bearing has been fitted to the carrier backwards. This will cause damage to the bearing and pressure plate as the bearing is not rotating due to incorrect installation.

FAQ's - Solid Flywheel Conversions

In some vehicles when converting from a dual mass flywheel to a solid one-piece conventional style flywheel you may experience some extra driveline harmonics. This is because we have gone away from the factory dual mass flywheel that has a sprung and hydraulically dampened centre that absorbs harmonics and vibrations between the engine and gearbox. 

When converting from dual mass to solid style flywheel we need to absorb the harmonics through the clutch plate centre and in most cases this possible. Some vehicles may get  excessive driveline harmonics and unfortunately in those vehicles the only way to correct that is to go back to a factory style dual mass flywheel and factory clutch. 

For the majority, a solid conversion flywheel with aftermarket clutch is acceptable and in vehicles that are used offroad or for towing the solid conversion package is a better option.
