An oversize crank journal can cause fit (clearance ) issue.

The only thing to much toque will do (if overdone enough) is possibly take the bolt into the plastic range. It does not squeeze the bearing cap (or bearing) any more as there is a mating of two flat fixed distance surfaces.

The purpose of the plasti gauge is not to check torque, its to check bearing clearance of which a small amout is required.

So what you have is a larger than normal crank surface or a too small of a bearing.

The second torque would be under torqued allowing it to turn but if you are into that arena, it will come undone.

It sounds like he needs oversized bearings to get the proper clearance with the right toque.


There, fixed it. And I agree. Or a line bore on the journals.
