positioned to service the rocker arms for cylinders 1, 2, 7 and 8.
7. NOTE: If servicing all rocker arms, or any of the rocker arms for cylinders 1, 2, 7 and 8, the remainder of this procedure must be performed
before rotating the crankshaft to prepare the engine to service cylinders 3, 4, 5 and 6.
If required, skip Step 8 and complete the rest of this procedure, for rocker arms on cylinders 1, 2, 7 and 8.
