Install the extension housing assembly (3) and bolts (1) to the J 44755 (2).
Tighten

Tighten the bolts to 25 N.m (18 lb ft).
Install a new nut (1) onto the shaft.

Tighten
- Tighten the nut, with new bearings to 250 N.m (185 lb ft).
- Tighten the nut, with used bearings to 200 N.m (148 lb ft).
Remove the extension housing assembly and bolts from the J 44755.
Measure in both directions, the rotating torque of the driveshaft. A properly assembled shaft and NEW bearings should have a rotating torque of 1.5 N.m (13 lb in). When reusing driveshaft bearings, the rotating torque should equal the value recorded during disassembly. Tighten the flange nut as required to achieve the proper rotating torque value.

Tighten

Tighten the bolts to 25 N.m (18 lb ft).
Measure the distance (x) between the J 44757-3 and the J 44757-9 using a feeler gage. Add the measured value (x) to 67.3 mm (2.65 in). Record the value as dimension D.
