fake ben taylor Posted June 22, 2016 Share Posted June 22, 2016 Hey guys, My car came with an unknown uprated clutch and Smf (hopefully find out when it all comes off) but the release bearing is rattling like mad and needs changing. When I did the clutch slave cylinder stop tech did an uprated version. Is there similar for release bearing? Thanks Link to comment Share on other sites More sharing options...

ZMANALEX Posted June 22, 2016 Share Posted June 22, 2016 Keep in mind that the idler gear can rattle quite badly with the SMF as there are no damping properties. Just saying, as well worth a check when you have the box out Also remember and have a squint at the first motion shaft / crankshaft bushing.

fake ben taylor Posted June 22, 2016 Author Share Posted June 22, 2016 Idler gear? In the box? Its an intermittent really bad rattle that goes silent when you press the clutch pedal down :/ First motion Shift buying a roller bearing type of oil impregnated brass?

ZMANALEX Posted June 22, 2016 Share Posted June 22, 2016 (edited) When you press the clutch, that is the only time that the release bearing is turning. EVERY other time it is stationery and not turning. Think about it. Also check the front gearbox bearing when the box is out.

fake ben taylor Posted June 22, 2016 Author Share Posted June 22, 2016 Lol im not daft, noisy release bearings nearly always quieten when the clutch is pressed, it still turns the other times just with no pressure and so bad ones rattle. Link to comment Share on other sites More sharing options...
Alex350z Posted June 22, 2016 Share Posted June 22, 2016 Sure its not just the single mass flywheel? I have one and its noisy unless you press the clutch in Link to comment Share on other sites More sharing options...

ZMANALEX Posted June 22, 2016 Share Posted June 22, 2016 http://www.edmunds.com/car-technology/when-fact-meets-friction-the-basics-of-clutch-operation.html Below in red is what really matters. In layman's terms, a pressure plate is a spring-loaded "clamp," which is bolted to the flywheel. It includes a sheetmetal cover, heavy release springs, a metal pressure ring that provides a friction surface for the clutch disc, a thrust ring or fingers for the release bearing, and release levers. The release levers lighten the holding force of the springs when the clutch is disengaged. The springs used in most pressure plates are of a diaphragm-type, however a few use multiple coil springs. Some high-performance pressure plates are "semi-centrifugal," meaning they use small weights on the tips of the diaphragm springs to increase the clamping force as engine revolutions increase. The "throw-out bearing" is the heart of clutch operation. When the clutch pedal is depressed, the throw-out bearing moves toward the flywheel, pushing in the pressure plate's release fingers and moving the pressure plate fingers or levers against pressure plate spring force. This action moves the pressure plate away from the clutch disc, thus interrupting power flow. Mounted on an iron casting called a hub, the throw-out bearing slides on a hollow shaft at the front of the transmission housing. The clutch fork and connecting linkage convert the movement of the clutch pedal to the back and forth movement of the clutch throw-out bearing. To disengage the clutch, the release bearing is moved toward the flywheel by the clutch fork. As the bearing contacts the pressure plate's release fingers, it begins to rotate with the pressure plate assembly. The release bearing continues to move forward and pressure on the release levers or fingers causes the force of the pressure plate's spring to move away from the clutch disc. To engage the clutch, the clutch pedal is released and the release bearing moves away from the pressure plate. This action allows the pressure plate's springs to force against the clutch disc, engaging the clutch to the flywheel. Once the clutch is fully engaged, the release bearing is normally stationary and does not rotate with the pressure plate. Link to comment Share on other sites More sharing options...
