About Getting the Flywheel turned

[RossY]

I am unable to disengage the clutch and i have narrowed it down to either the flywheel or the clutch itself. Now the question i have is whether or not it is necessary to have the flywheel turned or not. I didn't and my clutch will not disengage even with the clutch fork bottoming out on the tranny.

I can clearly see that the clutch is being pushed on by the throwout bearing. What gets me is that i changed my clutch before(swapped in a slightly used one) and i had no problems.

Hi,

What do you mean by turned?

If you mean machined to a certain step, then yes you have to do this. Here is a great link for it: http://www.roadraceengineering.com/clutchandflywheeltech.htm

yes turned = machined. It just gets me because i was able to swap out my old one with a different pressure plate and it still worked fine but now that i put a new one in it won't go into gear for nothing.

Hey man I dont know what to tell you about that, I always had mine machined becasue clutches can be real funky sometimes.

A flyweel is "surfaced", not turned (like a brake rotor). The condition of the friction surface is what determines whether it's needed or not.
An inability to disengage is usually a hydraulic problem, not a clutch failure. Worn clutches will lose their grip and let the engine race under load.

sounds to me like you may have a bent clutch fork. the hydralics are ok if your bottoming out the fork agaisnt the trans but it shouldnt be able to go that far.

I'll check the clutch fork when i get home. I know its only like a year old or so but what the heck.

I just replaced my clutch plate, pressure plate, and TOB with a XTD "stage 3" clutch kit. I didnt resurface/turn/machine my flywheel. It didnt have any warping, only a few small heat marks, and some very small cracks, the largest being 1mm deep or less and 3-4mm long. I already put everything back together. Should I take it back part to fix it or no?

I would have turned it. Does that clutch require a specific step like the ACT clutches do? With you saying that it had small cracks in it too if they didn't at least turn out then I would replace the flywheel. Where are those cracks? In the clutch surface or where it bolts up to the crank? If it's around the crankbolts then definately take it back apart and replace the flywheel.

It's always recommended to have your flywheel resurfaced when doing a new clutch. Or just buy a new one, they're only like $60

Any visible cracks scrap a flywheel. Or are you just speaking of checking? They're different phenomenon.
