When I first put this bike back together from pieces I installed new crank bearings. They are about 8 months old. When I turn them there is clearly a flat spot. I ordered new ones, I only want to rebuild this bike one last time so I might as well put new ones in with the new crank .


Now I wait for all the parts.

Do you have a set of "V" blocks or something to check the crank for straightness?

No. I just ordered a new one.

do you want the old one ? I'll be going down to TN in late September, I can drop it in the mail in PA on my way through.

Thanks, But no.
The reason I asked is because you will need to check straightness on the new one. These lil crankshafts can go out by picking them up wrong.

Don't mean to scare ya. The new crank should be true. Just handle it carefully.
