FLYWHEEL

Recommended Posts

Well, I pulled the flwheel off to get to the oil seal, I noticed the flywheel is significantly grooved. Just how bad can they be before you can't skim it.

"significantly grooved" is not good and should be ground. Be sure to check the specs for minimum thickness...maybe time for a new clutch while you're there.

You may get away with 0.5m (guesswork), possibly more but keep in mind the more metal you take away (and you must keep the step constant so have both bits machined) the less the flywheel is able to do its job (balance the engine running) and the less able it is to cope with slipping generating heat so it buckles more.

I've attached a picture.It's weird that half of the surface is scored and not the other?? I wonder if something got caught in there? As you suggest, time to replace the clutch...

Does any one know the minimum thickness of the flywheel?

:lol: 50cm deep, that would be one fat flywheel!!!

That doesn't look too dreadful. The scoring pattern is roughly what I'd expect. That centre groove would be roughly where the friction disc rivets would run. I presume you're putting in a new clutch?

Sure am!

I've had the flywheel skimmed. Came up a treat..

Interestingly, straight fingered cover and the wrong flat faced bearing!

I've got to say, the clutch was fine though, changed well, no slip etc etc.

Ordered a correct cover and driven plate from SJ.
