Steering box dismantling and reassembly: reassembly

Reassembly is the reverse procedure to dismantling but the following points should be noted:

1. All parts should be thoroughly cleaned before reassembling and during assembly liberally lubricated using Fiat W90/M oil (SAE90 EP).
2. The pitman arm nut should be correctly positioned on reassembly to the sector shaft and both are marked with notches or a master tooth on the sector will mate with a double tooth on the pitman arm which will prevent incorrect reassembly.
3. The pitman arm nut must be tightened to a torque wrench setting of 72 lb ft.
4. Fill the box up to the level and filler plug with SAE90 EP gear oil.

Refitting the steering box

To refit the steering box to the vehicle proceed as follows:

1. Engage the worm screw from the steering shaft by gently manipulating the steering box.
2. Replace the steering box to body nuts and tighten to a torque wrench setting of 14 to 18 lb ft.
3. Replace the two track rod pins in their seatings in the pitman arm and tighten the self-locking nuts to a torque wrench setting of 18 to 21 lb ft.
4. Replace the steering shaft to worm screw mounting bolt, lock washer and nut.
