1. Install O-ring seals (7) in torque converter housing (1).

2. Attach Tooling (A) and a suitable lifting device to pump drive (4). The weight of pump
drive (4) is approximately 32 kg (70 lb). Position pump drive (4). Install bolts (5) and (6).
Tighten bolts (5) and (6) to a torque of 100 ± 20 N·m (74 ± 15 lb ft).
3. Position shield assembly (3) and install bolts (2). Tighten bolts (2) to a torque of 28 ± 7 N·m
(20 ± 5 lb ft).

a. Tighten bolts (8) to a torque of 100 ± 20 N·m (74 ± 15 lb ft). Tighten bolt (9) to a
torque of 55 ± 10 N·m (41 ± 8 lb ft).
b. Measure the rolling torque for bearing (10) and record this measurement in N·m.
Note: If the torque exceeds 8 N·m (71 lb in), disassemble the unit and replace the
necessary components.
c. Rolling torque required for bearing (12) should be the torque measured from Step 3.b
multiplied by 0.8 and then add 2.02 ± 0.4 N·m. Record this measurement as the
required rolling torque for bearing (12). Tighten nut (11) until the required rolling
torque is achieved.
d. Secure nut (11) with lock (13).
