My big-end has endplay, the rollers are 0.247" so I replace them with standard 0.250" (Harley-Davidson rollers according to Dave Plump's advice) But they are to tight.
Are there undersize rollers ? 0.249" or 0.248"
John, I have just fitted harley rollers to one of my B33s, These too were a tight fit so I had the outer track on rod honed as well as the big end pin cleaned up to get the clearance needed, but as Ian says there are different sizes which are ok to fit if rod is not worn oval. Dave...
Hi, Harley rollers only start at .0250", they don't do undersizes, only oversizes, I suggest getting the rod honed a little to get them to fit and this will also refresh the service. Most good car engine rebuilders should be able to do it.

The conrod, crankpin and rollers are allready in a machine shop. Strange however was that allthough there was a (too) tight fit, the conrod turned freely. But when I give it a good push, after 5/6 turns it "moved" sideways and got clamped. Maybe someone hear the big-end in need of repair ?
