Is it flat? If you put a straight edge on it, radially, then can you see light under it? Try a feeler gauge under the straight edge, but I imagine that the thinnest feeler isn't going to find anything. 8K is nothing for age.This gonna seem like I’m being overly frugal, but how does this clutch look-View attachment 2490309View attachment 2490310
The friction plate looks good to my eye. I’m debating if I can reuse this for my lm7. The clutch has maybe 8k miles on it and I’d like reuse it on my sm465. I have new flywheel for back of the lm7, but I’d like save some money on the clutch.
Usually, there are specs for the thickness of the friction plate, thickness and depth of rivet head.
Resurfacing a flywheel reduces heat generated. Heat causes glazing and warping (surface hardening), which in turn causes more slipping, and more heat and subsequent cracking. A frequent flywheel resurfacing (maybe two digits in expenditure) would be proactive, preventative maintenance, reducing cracking and glazing. But the pressure plate and friction disc are most often, simply, replaced when needed. You will find discussion about catastrophic flywheel failure, but, I don't know if the same is true for the pressure plate. If I was winging it, I'd professionally resurface the flywheel, and random orbit sand the pressure plate at home - but, also, I never recommend others to just, 'wing it.'
