(c)
Install the main filter oil tube (35) to the top of the fluid pressure dampener (88). 1) With the two bolts (83), bolt threads lubricated with
antigalling compound, attach the main filter oil tube (35) to the fluid pressure dampener (88). 2) Tighten the bolts (83) with your hand.
(d)
Install the bolts (84), threads lubricated with engine oil, and nuts (85) that attach the clamps for the main filter oil tube to the main gearbox bracket at two places. 1) Tighten the nuts (85) to 32-36 pound-inches
(3.6-4.1 newton-meters).
(e)
Tighten the three bolts (34A) that attach the main filter oil tube (35) to the main oil filter housing (1) to 85-95 pound-inches (9.6-10.7 newton-meters).
(f)
Tighten the bolts (TBD) that attach the fluid pressure dampener (88) to the top of the scavenge pump to 62-72 pound-inches (7.0-8.1 newton-meters).
(g)
Tighten the bolts (84) and nuts (85) that attach the fluid pressure dampener (88) to the engine bracket (87) to 32-36 pound-inches (3.6-4.1 newton-meters).
(h)
Tighten the bolts (48) that attach the main filter oil tube (35) to the top of the fluid pressure dampener (88) to 62-72 pound-inches (7.0-8.1 newton-meters).
