Re-plating crankcase bolts

<< < (2/2)

McCabe-Thiele (Ted):
I do not know the definitive answer but my thought  process is that the ten bolts are essential crank main bearing bolts as opposed to the remaining crank case bolts that just secure the casing halves. Grade 8.8 is high tensile

Generally speaking crank case bolts would be high tensile.

Ash: Do you just use your witches brew for stripping every type of metal, be it high tensile or other? I.e. play it safe and just use your brew?

Also, Do you know if the crankcase bolts are high tensile?

Cheers

I mainly use it for spokes. I agree with Julie ..normal acid stripping OK for no9 crankcase bolts.

Fleabie:
Thanks all. Much appreciated as usual 🙂
