Roller bearings are not available in odd numbered sizes; therefore, when determining a plug fit, if the bearings are too loose with an even numbered roller bearing (example -.0008 in. oversize) and too tight with the next size even numbered roller bearing (.001 in. oversize), it must be assumed that an in-between odd size bearing (.0009 in. oversize) would achieve a plug fit. Running fit calculations are based on that assumption.

If lower end race of one rod is found to be slightly larger than the other, select rollers to fit the larger rod race and lap smaller rod race to same size as larger race rather than fitting rollers of two sizes.

When rods are correctly fitted with required bearing clearance, extreme upper end of the male rod will have .025 in. to 1/32 in. (.031 in.) side shake. All fitting and checking must be made with bearings, rods and crank pin free of oil and clean.

Fitting bearings tighter than described is likely to result in seizing and bearing damage when heat expands parts.

Check overall width of roller retainer assembly. It must be less than width of female rod end.
