(3) Torque for bolt ... 18 N·m (13 lb ft)
(4) Torque for nine bolts ... 14 to 15 N·m (10 to 11 lb ft)
(5) Torque for two plugs ... 14 to 25 N·m (10 to 20 lb ft)
(6) Displacement of charge pump ... 21.3 cm3/rev (1.3 in3/rev)
Charge pressure relief setting at NEUTRAL ... 1450 to 1520 kPa (210 to 220 psi)
(7) Torque for four bolts (rectangular pattern) ... 14 to 15 N·m (10 to 11 lb ft)
(8) Torque for hydraulic suction line connection (not shown) ... 19 to 26 N·m (14 to 21 lb ft)
(9) Torque for six bolts ... 38 to 48 N·m (27 to 37 lb ft)
Clearance between the left trunnion cover and case at assembly (shimmed) ... 0.36 mm (.014 in)
NOTE: Assemble left trunnion cover to case with 11.3 N·m (100 lb in) torque. Measure the clearance between the left trunnion cover and case at three equally spaced places. Average the three measurements. Remove left trunnion cover. Add or remove shim to provide for clearance specification of 0.36 mm (.014 in). Install left trunnion cover. Torque bolts to 38 to 48 N·m (27 to 37 lb ft).
(10) Torque for two charge check valves (under the charge pump) ... 40 to 55 N·m (30 to 40 lb ft)
(11) Torque for charge relief valve ... 40 to 80 N·m (30 to 60 lb ft)
(12) Torque for eight bolts ... 38 to 48 N·m (27 to 37 lb ft)
NOTE: Install two bolts (12) and tighten alternately until internal spring is compressed enough for the end cap to rest on the housing. Install the remaining bolts.
