Can somebody tell me please....iff the 0.05mm measured with plastigauge at the bearings is ok! From new...the book says a little lower.
What do you think? I should scrap the crank?
Thank You!
All the best!

Manaul says 0.058mm is top limit when new, wear limit is 0.16mm. I would say it's OK, but to be on the safe side you could get it re-ground and use oversize bearings.
