–  Press taper roller bearing outer race, without shim, into torque converter housing.

–  Press on taper roller bearing inner race onto differential housing.

–  Press on taper roller bearing outer race to stop into differential housing. –  Drive in onto stop with drift.

–  Press taper roller inner race into gearbox housing.

–  Screw converter housing onto gearbox support -VW 353- and insert differential. –  Place adjusting device for crown wheel -VW 521- into differential housing. –  Put on gearbox housing, insert every other bolt in area of differential and tighten to 25 Nm.

–  Assemble special tool to measure play. –  Preload gauge to 1 mm and then set to “0”. –  Move differential up and down. –  Read and note play on dial gauge. Determining thickness of shim The specified bearing preload is achieved when the preload of the bearings 0.12 mm and the amount for settling 0.10 mm are added to the measured value. Example:

Measured value		0.60 mm
+	Preload	0.12 mm
+	Amount for settling	0.10 mm
=	Thickness of shim to insert	0.82 mm

–  Unbolt gearbox housing and remove differential from torque converter housing.

–  Pull taper roller bearing outer race out of torque converter housing A -  Counter support, e.g. -Kukko 22/2- B -  Internal puller, 46...58 mm, e.g. -Kukko 21/7-

If the measured thickness is greater than shown in the table, it is possible to install 2 shims corresponding to the thickness of the shims to be inserted.

–  Press taper roller bearing outer race, with shim, into torque converter housing.
