Tigershark1976 Turbocharged June 10, 2012 Share June 10, 2012 Read from many ang moh forum where the flywheel should be resurface (aka skim the flywheel) before installing new clutch. but I dont see this as a common practice in SG. Is it a must to do so?? ↡ Advertisement Link to post Share on other sites More sharing options...
QQDreamer 4th Gear June 11, 2012 Share June 11, 2012 flywheel is for auto cars only? or manual also have? Link to post Share on other sites More sharing options...
Watwheels Supersonic June 11, 2012 Share June 11, 2012 (edited) flywheel is for auto cars only? or manual also have? Whether it's petrol or diesel engine, auto or manual, all has a flywheel. They resurface the flywheel probably is to remove the rust. Maybe they feel that the rust will affect the dynamic balance of the flywheel when it's turning. (Layman: the rust causes uneven weight distribution on the flywheel) Edited June 11, 2012 by Watwheels Link to post Share on other sites More sharing options...
Yeobh 4th Gear June 11, 2012 Share June 11, 2012 (edited) Normally flywheels with uneven wear or burn /glazed marks are grind down only a few thousand of an inch. The whole idea is to get a very flat and straight surface to the flywheel axis so as to get the best clutch plate contact withno slip when transmitting power.

Skyiet27 Clutched June 11, 2012 Share June 11, 2012 when ws down ur GB to replace clutch they can examine the condition of flywheel if theres a need to skim or replace better have it done due to down GB not cheap so in the case u same on labour as u no need to down again for future skim of fly but but last x when i driving manual n change gearing, clutch never once need to skim fly hahhahaa maybe u are rite seldom this practise locally as for me Link to post Share on other sites More sharing options...

Yeobh 4th Gear June 11, 2012 Share June 11, 2012 The cheapest tool for small shop is a piece of diamond impregnated oil stone. Manually polishing can help to remove some wear marks and ridges. Link to post Share on other sites More sharing options...

The whole idea is to get a very flat and straight surface to the flywheel axis so as to get the best clutch plate contact withno slip when transmitting power. Disk uneven wear can be easily inspect by visual, but if flywheel warp, I doubt its visible... There was once I found my wheel vibrate whenever I brake. I suspect its the brake disk. Bring it for a check and the guy tested drive and told me that its 99% disk brake but if turn out not, I will still have to pay for the skimming... took off the wheel and I see nothing wrong with the disk. No unusual mark, crack... in fact, its much smoother than my previous ride disk brake. But once they started to skim, can see a "patch" of the disk brake area not skimmed when the machines starts... They ran the machine 2 rounds to make sure that the whole surface is evenly skimmed and they did "balancing" to ensure that the disk is balanced after skimming...in the end, only 1 of the disk was slightly warp and other other side its fine but I have to pay for both....

Seen many mech changing clutch disk.... their eye is not even on the flywheel.. when changing the clutch plate, clutch cover and bearing.... ↡ Advertisement Link to post Share on other sites More sharing options...
