Renewing oil seal for flange shaft (left-side)

Special tools and workshop equipment required

t	Oil seal extractor lever -VW 681-

t	Thrust piece -T10387-

Procedure

l	Gearbox installed

–	Remove flange shaft (left-side) → multitronic 01J, front-wheel drive; Rep. Gr.39, → multitronic 0AN, front-wheel drive; Rep. Gr.39.

–	Pull out flange shaft oil seal using oil seal extractor lever -VW 681-.

Assembling flange shaft with polygon bearing

1 -	Flange shaft

2 -	Needle bearing (polygon bearing)

3 -	Spacer ring

4 -

Circlip

5 -	Not fitted

Note

t	Uneven running of the polygon bearings with the flange shaft not fitted is not a sign of a problem with the bearings. A test for noisy bearings can only be performed with the bearings installed.

t	Inspect for signs of damage to polygon bearings (such as cracking in outer race).

t	Renew flange shaft if polygon bearings are damaged

–	Lightly lubricate outer circumference and sealing lip of oil seal with gear oil.

l	Installation position: open side of oil seal points towards gearbox

Note

Take care to keep the oil seal straight when driving in.

–	Use the thrust piece -T10387- to evenly drive in the new oil seal for the left flange shaft as far as the thrust piece will go.

Note

t	Standard driving-in depth: 5.5 mm beneath the surface of the cover

t	Repair driving-in depth 6.5 mm (when using the thrust piece -T10387-) so that the new oil seal does not provide a seal on the old contact surface of the old flange shaft.

–	Install flange shaft (left-side) → multitronic 01J, front-wheel drive; Rep. Gr.39, → multitronic 0AN, front-wheel drive; Rep. Gr.39.

–	Check gear oil in front final drive → multitronic 01J, front-wheel drive; Rep. Gr.39, → multitronic 0AN, front-wheel drive; Rep. Gr.39.
