3 - Bearing/Bushing Installer - Multiple Use: VW295A 

• Installation position: labeling of the bearing -arrow A- (thicker wall thickness -arrow B-) points to the Bearing Installer - Wheel Bearing/Ball Bearing: 3074  -2-.

-- Then insert the roller needle bearing circlip -item 13-  OVERVIEW - CLUTCH HOUSING => List Item: Circlip.

-- Install the input shaft seal. Refer to INPUT SHAFT SEAL, REPLACING, CLUTCH HOUSING .

Slide off the Output Gear 1 of the Drive Wheel from the Pinion.

• Remove the hydraulic pressure reservoir. Refer to Vehicles with Self-Locking Center Differential .
• Beforehand, remove the circlip -item 6-  OVERVIEW - CLUTCH HOUSING => List Item: Circlip from the pinion.

2 - Press Piece - Output Shaft Gear/Final Drive Gear: 3002 

3 - Puller (Kukko 18/2): VAS251419 

4 - M14 x 1.5 Nut or M14 x 1.5 Wheel Nut

-- Attach the Puller -3- to the output gear -1- for the drive gear using the nuts -4-.

-- Warm the output gear -1- for the drive gear to approximately 100 °C (212 °F) using the Wiring Harness Repair Set - Hot Air Blower: VAS1978/14A  .

-- Counterhold on the Puller -arrow- when removing.

Detach the Parking Lock Gear

• Vehicles with self-locking center differential: remove inner output shaft. Refer to Inner Output Shaft Roller Bearing, Removing, Vehicles with Self-Locking Center Differential .

-- Release the lever for the parking lock -2- in direction of -arrow-, using pliers.

-- Remove the parking lock gear -1- upward from the pinion -3-.

Install the Drive Wheel Output Gear 5

1 - Spindle from Puller (Kukko 18/2): VAS251419 

2 - Nut

3 - Thrust bearing from Subframe Bushing Tool Kit: 3301 

4 - Press Piece - Trailing Arm: 2010 

• Beforehand, place the gear for the parking lock -item 4-  OVERVIEW - CLUTCH HOUSING => List Item: Parking Lock Gear on the pinion.
• Installation position of the gear for the parking lock: the high collar points to the drive wheel output gear.
• Output gear installation position: the reinforcement ridges -arrow A- face upward.

-- Install the nut -6- (M12) with the washer until the threads are flush.

• The total height of the nut -6- and the washer must not be more than 12 mm.
• The spindle -1- and the nut -6- must not contact the clutch housing -arrow C-.
• Vehicles with self-locking center differential: pay attention to the inner self-locking center differential!

-- Warm the output gear of the drive wheel -5- using the Inductive Heater: VAS6414  to approximately 120 °C (248 °F) and on the pinion in the installation position.

-- Then press on over the nut -2- of the output gear of the drive wheel -5-. At the same time counterhold on the hex fitting -arrow B- of the spindle -1-.

Determine the Circlip for the Output Gear of the Drive Wheel on the Pinion

Tip: 

• The output gear for the drive gear is pressed all the way on.
• The illustration shows a different component. However, determining the circlip is identical.

-- Determine the thickest (but still usable) circlip and insert it. For the part number. Refer to the Parts Information.

The following circlips are available:

Circlip Thickness (mm)
3.85	3.90	3.95
4.00	4.05	4.1
