Anyone else having issues opening the pics of the crank I posted on my google drive?
None of the rod bearing holders had evidence of over heating either, which is interesting noting the bearing condition.
Anyone know the grade of steel for the crank shaft? If it is thermally hardened, by intentionally creating martensite, cracks maybe normal depending on its size. The elasticity & forces (max & fatigue) on the steel will determine crack propagation time frame leading to ultimate failure or never propagate to failure. Apologies if I nerd-ed out a bit and bored some folks.
