Disassembly
-- Remove the grooved ball bearing locking ring.
-- Mount the thrust pad 16.5/28 mm dia. VW 431 and the thrust piece40-105 on the input shaft before mounting the puller.
-- Position the separating tool -B- in the surrounding groove inside the bearing for the locking ring.
A - Puller, for example, kukko puller 65-160 mm 18/1
B - Separating tool 12 to 75 mm, for example, kukko separating tool 12-75 mm 17/1
A - Separating tool 22 to 115 mm, for example, kukko separating tool 22-115 mm 17/2
Assembly
The groove -arrow- on the gear must face up.
The groove for the locking ring faces up -arrow A- and the collar -arrow B- must face the 5th gear.
Grooved Ball Bearing with a Rubber Ring -arrow-
The shoulder -A- on the thrust tube VW 454 faces the thrust disc VW 412.
-- Select the grooved ball bearing locking ring and install it on the input shaft. Refer to Fig 7.
-- Insert a 1.86 mm locking ring -A- into the groove in the input shaft and press it upward.
-- Measure the gap between the grooved ball bearing -B- and the installed locking ring -A- with a feeler gauge -C-.
-- Remove the locking ring used for the measurement.
-- Select the locking ring according to the table.
| Measured Value (mm) | Locking Ring Thickness (mm) | Axial Play (mm) |
|---|---|---|
| 0.01 ••• 0.05 | 1.86 | 0.01 ••• 0.05 |
| 0.05 ••• 0.07 | 1.89 | 0.01 ••• 0.05 |

-- Compress the cylindrical roller bearing locking ring -arrow- with pliers -C- and remove it.
A - Counter-support, for example, kukko support 22/2
B - Internal puller 30 to 37 mm, for example, kukko extractor 30-37 mm 21/5
-- Compress the cylindrical roller bearing locking ring -arrow- with pliers -C- and install it.
-- Remove the pliers before the cylindrical roller bearing gets into its installed position. The locking ring must lock into the groove on the clutch housing.
