Over the past 15 years, Adelaide Clutch Services has developed clutch systems and components for street performance and various motor sports.
Australia’s leading supplier and manufacturer of real performance clutches, the xtreme streetwise clutch range has been developed by globally sourcing the best products for each unique application. Our range is continually being increased to suit the rapidly growing performance market. New facing materials are continually being tested and developed to obtain the optimum performance.
We provide repair services to all products we sell, and take pleasure in repairing and upgrading other brand clutches.
Xclutch have manufacturing and remanufacturing facilities enabling testing and production of various types of clutches from 140mm to 430mm.
Xclutch has very strong links with all forms of Motor sports. We produce and sell clutches to suit street/drag cars to 1100hp . We continually get feedback from street, drag, drift, rally and all forms of motor sport that we are actively engaged in. We constantly are testing new materials to better performance and driveability.
Investigation of clutch non-release, slipping and shudder problems Has shown that a worn, damaged or incorrectly machined flywheel causes many of these problems. When fitting a new clutch to a
vehicle it is essential to ensure that the flywheel is in perfect condition in order to prevent any possible clutch problems.
Before fitting a new clutch, carefully inspect the flywheel for wear or damage. Minor scoring and grooving marks can be removed by machining, but if the contact surface is deeply scored the flywheel must be replaced. Scoring and grooving prevent the driven plate from contacting the flywheel evenly, resulting in clutch shudder and slipping problems. Surface glazing and heat marks must be removed by machining in order to prevent clutch slipping and shudder problems.
If the flywheel surface is heat-cracked or the flywheel runout exceeds 0,1mm, the flywheel must be replaced, as it is almost impossible to correct these faults by machining. A cracked or distorted flywheel is also a serious safety risk as it could burst while in the vehicle and cause severe injury to the driver and passengers. Flywheel runout must be measured with a dial indicator gauge mounted on the engine as illustrated in the sketch below.
Care must be taken to ensure that the specified flywheel profile is maintained by machining the cover assembly-mounting surface by the same amount as the contact surface. Where the flywheel has a step or recess, this must be machined exactly in accordance with the vehicle manufacturer's specifications in order to prevent clutch non-release and slipping problems.
The flywheel surface finish is also of critical importance in preventing clutch shudder or slipping problems caused by a flywheel surface, which is too smooth or too rough. A good guideline is to machine the flywheel face to the same surface finish as the new cover assembly pressure plate face.
Finally, the flywheel dowel pins, boltholes and starter motor ring gear must be checked for damage. Damaged or missing dowel pins must always be replaced in order to ensure correct location of the cover assembly on the flywheel, thereby preventing clutch problems caused by misalignment. Old dowel pins should not be re-used, as they will almost certainly have been damaged during removal from the flywheel.
Due to the introduction of new non-asbestos friction materials it has become essential to machine the flywheel surfaces to avoid clutch problems.
