Clutch F
Clutch F
Disassembling
- Rotate clutch - F -.
- Remove circlip - 1 - and remove plate pack - 2 - from cylinder "F".
- Press plate spring down under shop press using installation bracket (T10289).
- Remove split retaining ring - 1 -.
- Release shop press.
- Remove thrust piece and plate spring.
- Position cylinder "F" on clutch "D/G" with freewheel.
CAUTION!
Wear eye protection.
- Carefully press piston "F" with compressed air out of cylinder "F" as shown in illustration.
Assembling
CAUTION!
Before assembling, check clutch components "F" for wear and damage. Refer to => [ Clutch F ] Clutch F.
- Replace O-rings - 2 - and - 4 - for piston "F" - 3 -.
- Press piston "F" - 3 - into cylinder " F" - 1 - as far as stop.
- Place thrust piece - 5 -.
- Position plate spring - 6 -.
7 Split retaining ring
- Press plate spring down under shop press using installation bracket (T10289).
- Install split retaining ring - 1 -.
• Bent inner side at right angle of retaining ring faces downward.
- Release shop press.
- Insert waved washer - 2 - into cylinder "F " - 1 -.
- Install outer plate - 3 - and coated plate - 4 - alternately.
• Ensure rounded edges of last outer clutch disc faces toward lining disc - 4 - and not toward circlip - 5 -. This improves circlip contact surface.
- Insert circlip - 5 -.
Adjust clutch "F"
- Place clutch "F" on pre-tensioning tool (T10285).
- Place plate (T10292) on outer clutch disc "F".
• Plate must not touch circlip all around.
- Insert pressure unit (T10285/1) with centering pin into bore of plate.
- Align clutch "F" 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 inspection hole of pressure unit must align - arrow -.
- Apply Digital depth gauge (VAS 6087) at upper edge of cylinder "F", as depicted in illustration.
- Apply measuring tongue on outer plate and note measuring value.
- Mark contact point on cylinder "F".
- 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 "F" and pull plate pack upward until stop.
- When disc pack is pulled up, measure distance between upper edge of cylinder "F" 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 basis of the following calculus:
- Subtract average of measured values when plate pack is pulled up from average of measured values under load.
Clutch "F" air gap - Automatic Transmission 01V Front Wheel Drive
Clutch "F" 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.
