Insert waved washer - 2 - into cylinder "B" - 1 -.
Install outer plate - 3 - and coated plate - 4 - alternately.
Install thick outer plate - 5 -.

NOTE:

Ensure rounded edges of thick outer clutch disc faces toward lining disc - 4 - and not toward circlip - 6 -. This improves circlip contact surface.

Insert circlip - 6 -.

CAUTION: Illustration depicts current construction version of clutch "B" with waved washer - 2 - , 2x outer plates - 3 - and 2x coated plates - 4 -. Clutch "B" must be replaced on older versions without waved washer and with 3x lining and outer discs each.

Adjust clutch "B" air gap

Fig 8: Place Clutch "B" On Pre-Tensioning Tool T10285

Place clutch "B" on pre-tensioning tool T10285.
Place plate T10294 on outer clutch disc "B".

Plate must not touch circlip all around.

Insert pressure unit T10285/1 with centering pin into bore of plate.
Align clutch "B" on plate of pre-tensioning tool.

The pressure unit must be centrally positioned under spindle thrust piece.

Turn spindle of pre-tensioning tool downward.

The markings at the inspection hole of the pressure unit must align - arrow -.

Insert dial gauge VAS 6080 into measuring bar VW 382/7 and tighten knurled nut.
Apply measuring bar at upper edge of cylinder "B" , as depicted in illustration.
Check whether measuring bar makes proper contact at edge of cylinder "B".
Position measuring tip on outer plate and note measuring value.

Mark exact contact point on cylinder "B".
Repeat measurement at 2 other points of outer plate, 120° offset each, and mark contact points.
Average over 3 measured values under load.
Release spindle and remove plate.

Fig 9: Reach With Both Hands Into Clutch "B" and Pull Plate Pack Upward Until Stop

Reach with both hands into clutch "B" and pull plate pack upward until stop.
When disc pack is pulled up, measure exact distance between upper edge of cylinder "B" and outer disc (2nd technician required) at one of the marked points.
Repeat measurement at 2 other marked points of outer plate.
Average over 3 measured values when plate pack is pulled up.

Determine air gap on the basis of the following calculations:

	Average of measured values under load (value 1 + value 2 + value 3): 3
	Measurement when plate pack is pulled up (value 1 + value 2 + value 3): 3
=	Air gap

Subtract average of measured values when plate pack is pulled up from average of measured values under load.

If specified value is not obtained:

Determine new circlip - 1 - according to the following table.

NOTE:

Disregard - 2 -.
Air gap too small: Install respectively thinner circlip.
Air gap too large: Install respectively thicker circlip.

Available circlips - thickness in mm

0.8	1.4	2.0
1.0	1.6
1.2	1.8

Check air gap of circlip again after inserting.
