Could use some help for those who know OEM Cranks & Dampers on BBC
71 402, replacement parts. The crank wasn't changed.
I'm mostly sure this harmonic balance is a direct replacement. It's bottomed out. Seems the front surface on both should be flush, because it takes a 2" washer. Why wouldn't it be flush? No problem pulling the damper to double check it's a direct replacement, but can a new seal take it? The bolts on the timing chain cover were loose when I lined up the damper, so the alignment is dead-on and wouldn't change. Wish I had checked the original. Appreciate any input, thanks.
