Clutch C
Clutch C
Disassembling
- Twist ATF pump.
- Remove circlip - 1 - and remove plate pack - 2 - from cylinder "C".
- Press plate spring down under shop press using installation bracket (T10289).
- Remove split retaining ring - 1 -.
- Release shop press.
- Remove dished washer - 5 -.
CAUTION!
Wear eye protection.
- Carefully press piston "C" out of ATF pump with compressed air.
Assembling
CAUTION!
Before assembling, check components of clutch "C" for wear and damage. Refer to => [ Clutch C ] Clutch C.
- Replace O-rings - 2 - and - 4 - for piston "C" - 3 -.
- Press piston "C" - 3 - into ATF pump - 1 - until 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 -.
• Bent inner side at right angle of retaining ring faces downward.
- Release shop press.
- Insert waved washer - 2 - into cylinder "B " - 1 -.
- Install outer plates - 3 - and coated plates - 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 -.
Adjust clutch "C" air gap
- Secure pre-tensioning tool (T10285) with wide base in vise.
- Place ATF pump on pre-tensioning tool.
• Stator shaft projects through bore in base plate.
- Place plate (T10295) on outer clutch disc "C".
• Plate must not touch circlip all around.
- Insert pressure unit (T10285/1) with centering pin into bore of plate.
- Align ATF pump 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 the pressure unit must align - arrow -.
- Apply Digital depth gauge (VAS 6087) at upper edge of outer plate carrier "C", as depicted in illustration.
- Apply measuring tongue on outer plate and note measuring value.
- Mark contact point on outer plate carrier "C".
- 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 "C" and pull plate pack upward until stop.
- When disc pack is pulled up, measure distance between upper edge of outer disc carrier "C" 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 "C" air gap - Automatic Transmission 01V Front Wheel Drive
Clutch "C" 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.
