Clutch B

Clutch B

Disassembling

- Rotate clutch "B".

- Remove circlip - 1 - and remove disc pack - 2 - from cylinder "B".





- Press plate spring down under shop press using installation bracket (T10289).





- Remove split retaining ring - 1 -.

- Remove dished washer - 5 -.





- Release shop press.

CAUTION!
Wear eye protection.

- Carefully press piston "B" out of cylinder " B" with compressed air, to do so plug free oil bore using finger.





Assembling

CAUTION!
Before assembling, check components of clutch "B" for wear and damage. Refer to => [ Clutch B ] Clutch B.

- Replace O-rings - 2 - and - 4 - for piston "B" - 3 -.





- Press piston "B" - 3 - into cylinder " B" - 1 - as far as stop.

- Position plate spring - 5 -.

6 Split retaining ring

- Press plate spring down under shop press using installation bracket (T10289).





- Install split retaining ring - 1 -.

- Release shop press.

- Insert waved washer - 2 - into cylinder "B " - 1 -.





- Install outer plate - 3 - and coated plate - 4 - alternately.

- Install thick outer plate - 5 -.

• 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

- 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.

- 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:





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

Clutch "B" air gap - Automatic Transmission 01V Front Wheel Drive





Clutch "B" air gap - Automatic Transmission 01V All Wheel Drive





If specified value is not obtained:





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

• Disregard - 2 -.

• Air gap too small: Install respectively thinner circlip.

• Air gap too large: Install respectively thicker circlip.





- Check air gap of circlip again after inserting.
