Insert waved washer - 2 - into cylinder "A" - 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 -.

Adjust clutch "A" air gap

Place clutch "A" on pre-tensioning tool T10285.
Place plate T10293 on outer clutch disc "A".

Plate must not touch circlip all around.

Insert pressure unit T10285/1 with centering pin into bore of plate.
Align clutch "A" 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 -.

Apply Digital depth gauge VAS 6087 at upper edge of cylinder "A" , as depicted in illustration.
Apply measuring tongue on outer plate and note measuring value.
Mark contact point on cylinder "A".
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 "A" and Pull Plate Pack Upward Until Stop

Reach with both hands into clutch "A" and pull plate pack upward until stop.
When disc pack is pulled up, measure distance between upper edge of cylinder "A" 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 pate pack is pulled up.

Determine air gap on 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.

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

1.0	1.6	2.2
1.2	1.8	2.4
1.4	2.0	2.6
