If the extractor comes out of the hole in the dished washer, then use the next larger extractor.
-- Install the thrust washer 3401 with the shoulder -arrow- on the dished washer -A-.
Press-in depth for the dished washer is approximately 2.20 mm.
-- Remove the locking ring.
-- Switch the locking collar 1st/2nd gear to 1st gear.
-- Attach the pulling hooks under the splines (not selector splines) for the 2nd gear.
A - 2-arm puller, for example 20/10
-- Remove the locking ring.
Due to the fit between the synchronizer hub and the output shaft, these components can be remove by hand on some transmissions.
-- Clamp the output shaft in a vise. Use jaw protectors. -B-.
-- Remove the thrust washer alternating between sides from the output shaft using a drift -C- being careful not to damage the splines.
-- Place the >>larger<< axial needle bearing -2- on the output shaft thrust washer -1-.
- The needles must point upward toward the thrust washer -arrow A- and the flat side -arrow B-.
-- Install the needle bearing -3- and 1st gear -4-.
-- Install the >>smaller<< axial needle bearing -5- on the 1st gear.
- The needles must point upward toward the gear -arrow C- and the flat side -arrow D-.
-- Press the inner race onto the taper on the gear and measure the gap dimension -a- with a feeler gauge.
| Gap Dimension -a- | Installed Dimension | Wear Limit |
|---|---|---|
| 1st and 2nd gear | 0.75 to 1.25 mm | 0.3 mm |
-- Install the synchronizer ring, outer race and inner race onto the taper of the selector gear and then measure the gap dimension -a- with a feeler gauge.
| Gap Dimension -a- | Installed Dimension | Wear Limit |
|---|---|---|
| 1st and 2nd gear | 1.0 to 1.8 mm | 0.5 mm |
-- Install the inner race -A- on the 1st gear.
- The angled tabs -arrows 1- face the outer race -B-.
-- Install the outer race -B-.
- The tabs -arrows 2- must lock into the retainers -arrows 3- in the gear.
-- Install the synchronizer ring -C-.
- The retainers -arrows 4- lock in the braces -arrows 1- on the inner race -A-.
-- Mount the smaller axial needle bearing (outer diameter: 58.7 mm) -5- on the 1st gear. Refer to Fig 7.
-- Remove the springs -1- for disassembling.
- Spring
- Locking piece
- Locking collar >>installed position<<, refer to Fig 13.
- Synchronizer hub >>installed position<<, refer to Fig 13.
-- Slide the locking collar over the synchronizer hub.
- Installed position: The narrow recesses in the synchronizer hub align with the recesses in the locking collar.
Different locking collars are installed:
| -A- | ||
|---|---|---|
| The chamfer -arrow 1- faces the lower inner collar of synchronizer hub | ||
| The shoulder -arrow 2- faces the higher collar on the synchronizer hub |
| -B- | ||
|---|---|---|
| Collar -arrow 3- and collar -arrow 4- are the same size = installed position. |
- The locking collar is pushed over the synchronizer hub.
-- Install the locking pieces and springs offset by 120°.
- The angled end of the spring must engage into the hollow locking piece.
The high inner collar of the synchronizer hub -arrow- faces the 2nd gear.
Insert the 2nd gear synchronizer ring so that the cut-outs engage in the engagement pieces of locking collar.
The tabs -arrows- face the synchronizer hub/locking collar -A-.
The tabs -arrows 1- engage into the holes -arrows 2- inside the synchronizer ring -B-.
-- Install the 2nd gear needle bearing.
The higher collar -A- faces toward 1st gear -B-. The notches in the collar -arrow- lock into the tabs on the outer race. Refer to Fig 15.
-- Install the inner race/tapered roller bearing into the clutch housing. Refer to Fig 22.
Removing the inner race/tapered roller bearing inside the transmission housing. Refer to Fig 3.
A - Support, for example, 22/2
B - Extractor 46-58 mm, for example, 21/7
-- After removing, install the new shim with the former size under the outer race.
-- Support the transmission housing under the bearing mount using the arbor 50 mm dia. VW 432.
A - Separating tool 22-115 mm, for example 17/2
-- Install the locking ring.
A - Support, for example 22/4
B - Extractor 56-110 mm, for example 21/89
To be able to mount the extractor -B- the oil deflector collar must be changed using a drift. Replace the damaged oil deflector ring.
After removing, replace the damaged shim.
-- Install the new oil deflector.
-- Install the new shim with the former size under the outer race.
-- Support the clutch housing using the tube 60 mm dia.VW 415 A directly under the bearing mount.
