Reply To: Starter Clutch Warning….

[Laudanum]

Fair comment, I’m not saying that high tensile bolts are a bad idea, I just think that the problem is more due to the bolts coming lose in the first place than their strength.
Soon find out if we all fit stronger bolts and the backplates start shedding their threads if there is a linear force.
Couple of other things, at least if the bolts shear off the clutch just spins in situ, with high tensile there is nowhere for them to go. The second point is that there may be a reason why the bolts are en8, a standard en8 bolt has a degree of elasticity possibly to take up the shock loading from the starter clutch engaging.
Could be you replace the bolts and move the problem elsewhere…
