Installing the Bearing Inner Race/Tapered Roller Bearing on the Output Flange

• There are different installed locations for the output flange seal and bearing inner race/tapered roller bearing:

• The output flange seal is inside the pinion housing.
• Install the bearing inner race/tapered roller bearing on the output flange. Refer to Installing the Bearing Inner Race/Tapered Roller Bearing on the Output Flange 

• The seal and the bearing inner race/tapered roller bearing is located on the output flange.
• Install the seal and bearing inner race/tapered roller bearing on the output flange. Refer to figure below.

Refer to the parts information for the allocation.

-- Remove the bolts for the pinion housing -1- ; and carefully remove the pinion housing diagonally of the protruding edges.

-- Remove the pinion housing and the shaft bevel gear -2-.

-- Clean the thread on the shaft bevel gear.

• Insert the new shim -3- into the pinion housing.
• This ensures the bearing pre-load of the shaft bevel gear in the pinion housing.

-- Place the old bearing inner race/tapered roller bearing -1- into the pinion housing.

-- Install the new output flange seal -2-, if necessary.

-- Coat the outer circumference of new output flange seal -2- lightly with oil.

-- Slide a new O-ring -1- onto the pinion housing -2-.

The pinion housing -2- and shim -3- only fit in one position.

-- Install the previous shim -3-.

-- Carefully install the pinion housing diagonally all the way with :VW460/2  .

There is very little space between the pinion housing and the bevel box housing.

The gap is closed when the pinion housing is tightened.

-- Tighten the bolts for the pinion housing -2- diagonally.

If the Output Shaft Seal arrow is Inside the Pinion Housing, Then Install the Output Flange as Follows:

-- Clean any remaining locking fluid from the thread on the shaft bevel gear.

• Insert the new shim -2- into the pinion housing.
• This will maintain the bearing pre-load on the shaft bevel gear -1- inside the pinion housing.

-- Place the old bearing inner race/tapered roller bearing -3- into the outer race inside the bevel box.

-- Install a new seal -4-, if necessary. Refer to DRIVESHAFT OUTPUT FLANGE SEAL ON BEVEL BOX, REPLACING .

-- Fill the space between the sealing lip and the dust lip halfway with Sealing Grease.

Note the following: 

• Use a new removal hook.
• To not tilt the output flange.
• Mount the hooks on the bottom of the pinion housing.
• Tension the removal hook with the Two-Arm Puller -arrows-.
• Do not bend the removal hook toward the outside.
• Interrupt the procedure if necessary, remove the output flange again and repeat the process.
