Work Procedure
• Transmission removed
• Observe general repair information. Refer to => [ General Repair Information ] General Repair Information.
• Rules of cleanliness for working on transmissions. Refer to => [ Clean Working Conditions ] Clean Working Conditions.
Disassembling
- Remove the input shaft. Refer to => [ Input Shaft ] Input Shaft.
- Remove the input shaft cover from the shaft. Refer to => [ Torsen Differential Cover ] Service and Repair.
- Place the input shaft on assembly tool (T10219/1).
- Carefully raise thrust plate and pistons with two screwdrivers - arrows -.
Precautionary measures:
CAUTION!
• The inner running and sealing surfaces - arrow A - of the thrust plate and pistons - arrow C - must not touch shaft during removal and installation.
• The running and contact surfaces must not show the smallest signs of damage such as scratches or grooves as a result of removing or installing.
• If damaged, the thrust plate or pistons must be replaced.
- Carefully guide the thrust plate - 1 - with pistons - 2 - up over shaft - 3 -.
• Inner running surfaces of thrust plate - 1 - and pistons - 2 - must not touch shaft.
Disc Pack, Removing
- Remove corrugated spring washer - 5 -, they must be used again.
- Remove upper adjustment disc - 4 - from input shaft cylinder - A -.
- Measure adjustment disc thickness - 4 - and note measurement.
- Remove all lining discs - 2 - and outer discs - 3 - from input shaft cylinder - A -.
- Remove lower adjustment disc - 1 - from input shaft cylinder - A -.
- Measure adjustment disc thickness - 1 - and note measurement.
CAUTION!
• All old, used adjustment discs, outer discs and lining discs must be replaced. They must not be reinstalled as that would not ensure the input shaft function (surface is used up).
• The corrugated spring washer must be used again.
Assembling
CAUTION!
Before assembly, check for wear on transmission components. Refer to => [ Input Shaft Checking for Wear ] Testing and Inspection.
- Replace the ball bearing in the input shaft cover. Refer to => [ Input Shaft Cover Ball Bearing ] Input Shaft Cover Ball Bearing.
- Adjust the input shaft and determine air gap. Refer to => [ Input Shaft Adjusting with Air Gap Determination ] 01J Transmission.
- Place the input shaft on the assembly tool (T10219/1).
- Insert determined lower adjustment disc - 1 - in input shaft cylinder - A -.
- Insert alternately and with same alignment each lining disc - 2 - (6 pieces) and outer disc - 3 - (5 pieces, 1.9 mm thickness).
Lining disc alignment:
CAUTION!
• The lining discs must be installed with the same alignment, that is the places without outside teeth - arrows - must always lie one on top of the other. Only in this way is the adjustment correct; you must mark the cylinder for correct installation, if necessary.
- Insert determined upper adjustment disc - 4 - in input shaft cylinder - A -.
- Lastly, insert corrugated spring washer - 5 -.
- Press pistons - 1 - into stop on thrust plate - 2 -.
CAUTION!
• The inner running and sealing surfaces - arrow A - of the thrust plate and pistons - arrow C - must not touch shaft during removal and installation.
• The running and contact surfaces must not show the smallest signs of damage such as scratches or grooves as a result of removing or installing.
• If damaged, the thrust plate or pistons must be replaced.
- Carefully guide pressure plate - 1 - with pistons - 2 - down over shaft - 3 -.
• Inner running surfaces of thrust plate - 1 - and pistons - 2 - must not touch shaft.
- Press thrust plate with pistons uniformly into input shaft up to stop.
Checking air play with feeler gauge (T40117)
- Insert both feeler gauges (T40117) under thrust plate - A -.
- A second technician must push thrust plate - A - down to stop - arrow 1 - with Tube (VW 416 B).
- Guide both feeler gauges (T40117) circularly in direction of - arrow - back and forth under thrust plate.
• Both feeler gauges (T40117) must be guided oppositely.
• Feeler gauges (T40117) must not be angled.
• Entire circular area must be checked.
• Both feeler gauges (T40117) must always move freely without slightest resistance.
If feeler gauges (T40117) cannot be guided in direction of - arrow - without blocking:
- Repeat input shaft adjustment. Refer to => [ Input Shaft Adjusting with Air Gap Determination ] 01J Transmission.
CAUTION!
Air play must pass check with feeler gauges (T40117), otherwise transmission will exhibit problems after reassembly.
If feeler gauges (T40117) can be guided in direction of - arrow - without blocking:
- Install input shaft cover. Refer to => [ Torsen Differential Cover ] Service and Repair.
- Install input shaft. Refer to => [ Input Shaft ] Input Shaft.
- Install input shaft seal - A -. Refer to => [ Input Shaft Seal ] Input Shaft Seal.
- Fill with ATF. Refer to => [ ATF Filling for Flushing Process ] ATF Flushing.
CAUTION!
• The Multitronic 01J or 0AN transmission requires a different ATF than shift automatics. Only ATF for CVT transmission which can be obtained as replacement part must be used in planetary gearing.
• Flush ATF after installing transmission. Refer to => [ ATF Flushing ] ATF Flushing.
