Dual Clutch, Adjusting (Determining Circlip Thickness)
-- Find the circlips with a 2 mm thickness in the replacement part package.
- For the initial measurement, temporarily insert the 2 mm circlip and then, after the measured value has been calculated, replace it with the final circlip.
-- Insert a 2 mm circlip -arrow-.
-- Attach the :VW387 to the transmission flange.
-- For the first measurement, place the dial gauge measuring tip onto the input shaft as shown.
-- Set the dial gauge to "0" with 2 mm pretension.
-- Raise the dual clutch all the way upward.
-- Read and note the measurement result (= input shaft axial play).
-- For the second measurement, place the dial gauge measuring tip on the inner clutch plate carrier hub as shown.
- The measuring tip must not be placed on the circlip.
-- Set the dial gauge to "0" with 2 mm pretension.
-- Raise the dual clutch all the way upward.
-- Read and note the measurement result.
The new circlip is determined according to the following formula:
Circlip = 2. Measurement - 1. Measurement + 1.85 (= constant value)
The new circlips are staggered in 0.1 mm increments. Round to the closest number when selecting: up to 0.049 is rounded down, and from 0.050 is rounded up.
Example:
- Determined dimension for new circlip: 2.27 mm; new circlip rounded up to 2.3 mm thick.
- Determined dimension for new circlip: 2.24 mm; new circlip rounded down to 2.2 mm thick.
- If the determined dimension for the new circlip is 2 mm, the circlip that was temporarily inserted remains installed.
-- Remove the 2 mm thick circlip that was temporarily inserted for measurement and replace with the circlip of the determined thickness.
- The circlips may be used only one time.
- Dispose of the removed circlip that was inserted temporarily as well as the remaining circlips.
-- Insert the pump shaft by lifting the pump shaft and turning it slightly -arrow- so that it slides all the way into the splines.
-- Insert the drive plate into the dual clutch.
- The drive plate protruding tab -arrow- must be installed between the color-marked teeth or the markings that were applied later to the outer clutch plate carrier.
-- Install the drive plate circlip.
- Installation position: the drive plate tab and the color-marked teeth or the markings that were applied later to the outer clutch plate carrier must lie between the ends of the circlip.
-- Using a screwdriver, check to make sure the circlip is completely engaged.
-- Remove the :T10303 between the dual clutch and the housing.
Risk of Leaks on the Clutch End Cover.
Transmission Damage Due to Oil Loss.
- Do not touch the seal in the inner opening of the clutch end cover!
- Do not load the clutch end cover by hitting with a hammer.
-- Clean the contact surface for the outer clutch end cover seal.
-- Remove the clutch end cover from the replacement part package. Only grab the clutch end cover at the outer edge.
-- Clean the end of the transmission shaft.
- Only the outer clutch end cover seal may be coated with transmission fluid.
- If there are stickers on the outside or inside of the clutch end cover, they must be removed without leaving any residue.
