Before refitting worn main bearings, lap outer races to true them and remove any trace of wear shoulder at sides of roller paths using Harley-Davidson special lap. Part No. 11954-40 (see Illus. 48). Note: Before lap can be inserted in crankcase bushings, bearing washers, bearing spring rings and oil retaining bushing must be removed from the crankcase bushings. A race that is worn .0005" or more should be renewed.

When lapping main bearing races, right and left cases must be assembled and three or more studs
