Conditions:

• ● Bevel box removed .

• ‒ → Pressing taper roller bearing outer race, without shim, into torque converter housing.

• ‒ → Pressing taper roller bearing inner race onto differential cage.

• ‒ → Pressing taper roller bearing outer race onto stop in differential housing.
• ‒ Drive fully onto stop with drift.

• ‒ → Pressing taper roller bearing inner race into differential cage.

• ‒ → Bolt torque converter housing onto gearbox holder VW 353 and insert differential.
• ‒ Insert special tool into differential housing.
• ‒ Place gearbox housing on, and in the area of the differential gearbox fit every second bolt, then tighten to 25 Nm.

• ‒ → Assemble special tool to measure play.
• ‒ Preload gauge to 1 mm and then "0".
• ‒ Lift and lower differential.
• ‒ Read off and note play on gauge.

When performing measurement, do not turn differential otherwise the bearings will settle and the result of the measurement will be falsified.

Determining shim

The specified bearing preload is achieved if the bearing preload of 0.12 mm and the settling amount of 0.10 mm is added to the figure obtained from the measurement.

Example:

• ‒ Unbolt gearbox housing and remove differential from torque converter housing.
• ‒ → Pull taper roller bearing outer race out from torque converter housing.

A - Kukko 22-2 Counter-support

B - Kukko 21/7 Inner puller

Table of shims for differential

If the thickness measured is greater than the sizes in the table then 2 shims equal to the thickness of the shim to be inserted may be used.

• ‒ → Pressing taper roller bearing outer ring, with shim, into torque converter housing.
