Precautions

·Each point indicated in the mounting positions shown in Figure 8D-3 represents (starting at top) the oil plug (PT1/2), oil level (VA), and drain (PT1/2).·The mounting positions correspond to code i for the indexing, oscillating, and roller drives. ·The oil levels indicated in Figure 8D-3 are given in general figures and will differ according to the profile of the cam and the number of cam followers.
