Pinion housing has been removed from rear axle housing .

Dismantling

• ‒ Lever seal out.
• ‒ → Remove hexagon nut for shaft bevel gear.

• A - Ring spanner SW41
• B - Torque wrench - turn clockwise to remove

Use reducer 3/4 " to 1/2 " if necessary.

• C - Vice clamps

• ‒ → Drive small taper roller bearing outer race out from pinion housing.

• ‒ → Press large taper roller bearing outer ring out from pinion housing.

• ‒ → Pulling large taper roller bearing inner race off shaft bevel gear.

Assembling

• ‒ → Press shaft bevel gear small taper roller bearing outer race into pinion housing.

• ‒ → Press shaft bevel gear large taper roller bearing outer race into pinion housing.

• ‒ → Press large taper roller bearing inner race onto shaft bevel gear.
• ‒ Fit shaft bevel gear in pinion housing.
• ‒ Place on a new distance sleeve.
• ‒ Place small taper roller bearing inner race on shaft bevel gear.

• ‒ Fit hexagon nut to shaft bevel gear.
• ‒ → Tighten hexagon nut to 120 Nm, then measure friction torque => Page 39-174, if necessary increase tightening torque further until the correct friction torque is set.

• A - Ring spanner 41 mm AF
• B - Torque wrench - to screw on turn anti-clockwise

Use reducer 3/4 " to 1/2 " if necessary.

• C - Vice clamps

Increase tightening torque slowly and check friction torque at regular intervals. If the prescribed friction torque is exceeded, the spacer sleeve must be renewed and the adjustment repeated. A spacer sleeve which has been compressed too much cannot be reused.

Set friction torque as follows:

    1)    run at least 50 km (30 miles)

• ‒ → Measure friction torque.

• With torque gauge, 0 ... 600 Ncm, commercially available

A - protective jaws

• ‒ Drive new seal in onto stop with sleeve 3339. When doing this do not cant seal.
