Procedure

Follow the complete installation procedure and numbered diagrams on PDF pp. 678–680. These are the oil-pipe retaining bolts, not the large oil-pipe unions. Install the oil pipe and housing temporarily first, then progressively tighten; the grouped record does not replace the seven-fastener sequence.
