Has anyone had an issue with the tolerances on the inner races of the super blend bearings? I have 2 brand new bearings and one inner race is a tight fit and the other slides over the crank and can be turned by hand? I would have thought that both inner races would be a tight fit on the crank. Any thoughts on this one? Drummer99

It is OK if the timing side bearing is slip fit as the crank is slightly smaller on that end. The oil pump drive gear will hold it tight.

If the bearing on the drive side is loose then that will need to be repaired by building up the crank.

If the bearings are actually different inside diameters then I would return them. Jim

Have you measured the bearings? Crank?
