Crank Mileage

RichG » Sat Oct 09, 2010 7:23 am

Do you know how many miles / kms the crank has done? They won't last forever, even if you renew the 3 main bearings (centre one with integral seal) with a crank rebuild, you also have the big end needle rollers to think about, and eventually the fatigue life of the con-rod. What you should avoid at all cost is splitting your cases, renewing just the Left & Right seals, then discovering a short while later a much bigger crank job is required.
