Ditched the ARP bolts and gone to 12.9 socket cap bolts with Atomic washers 3x 11mm dowels, welded to the flywheel. Bolts tightened to 90ft/lbs Made up a plate with 6 holes in it which fits over the bolts and then welded each of the bolts to the plate. Next crank I put in it, I will be looking at running 12 bolts. 1 Link to comment Share on other sites More sharing options...

If the welded flywheel bolts are still all good what could be causing the damage to the clutch then?I've tryd 2 ace clutchs plus 1 other brand which I can't remember at moment & still has the same problem.When there fitted they feel fine but after being on the dyno & driven for a few weeks it develops a shutter & is hard to get into 1st & reverse.Don't really want to go & weld the bolts in on the new set up untill I know whats causing it & fix it.

May hold. The hardness of 12.9 also makes them subseptable to hydrogen embrittlement what you have done sounds good in the theory . But I would say they will crack at the welds.

I have broken one bolt but I don't think there is much I can do with the brinelling on the crank and the lack of surface to mount to. The crank will have to come out and be repaired at some stage but until then I'm happy pulling the box out every couple of months! Link to comment Share on other sites More sharing options...
