Re: Crankshaft Taper

I have tried this in the past. It's success was only good for a year or so.
Finally the crank broke it was crack checked beforehand.
I have always since believed that a tiny fractional difference from the front to the back caused a slight hormonic which in the end resulted in the eventual disaster.
Given that there are various new cranks available and still plenty of secondhand ones if budget is an issue, I would strongly recommend that you consign your current crank to the bin.
It's a lot of work and damage to put right if it breaks, not worth the risk in my view.

If you do decide to take the plunge with a new crank, I would strongly recommend that you get it dynamically balanced as I have never had one that was (even though they supposedly are).

Hope I do not sound too negative, but I wanted to share my experience with you.

Thanks for all the good advice. New crankshaft now fitted and engine rebuild in progress.
