SACHS Clutch: Notes

WARNING: This page is about a different car, the 2009 Audi TT and 2008 Audi TT. However, it is still accessible from the selected car via links, so may be relevant.

Special tools and workshop equipment required

Flywheel Retainer 3067
Centering Pin T10097
Grease for clutch disc shaft splines G 000 100

Removing

Transmission removed, refer to TRANSMISSION, REMOVING .

When removing, loosen the bolts as follows, so that the pressure plate does not distort (causing shuddering on acceleration):

-- Insert 3067 to loosen bolts.

-- Loosen all 6 bolts clockwise, one after the other and in steps of 90° (¹ /₄ turn) until the pressure plate is free.

When removing, stop -2- must loosen together with pin -1-.

-- If the stop does not loosen: push the bolt toward the dual mass flywheel.

-- Remove the pressure plate and the clutch plate.

Installing

Tightening specification, refer to SACHS CLUTCH ASSEMBLY OVERVIEW .

Install in reverse order, paying attention to the following:

NOTE:

Dual-mass flywheel, pressure plate and clutch plate are allocated to each other and must not be mixed with other manufacturer's components.

Only replace the clutch plate and pressure plate together.

To reduce odor caused by a burnt clutch, thoroughly clean the transmission housing around the clutch as well as the engine on the transmission side.

Clean the input shaft splines on a used clutch plate, the hub splines, remove corrosion and apply only a very thin coating of grease G 000 100 onto the splines. Then move clutch plate back and forth on input shaft until the hub moves freely on the shaft. Excess grease must be removed.

The clutch pressure plates are corrosion-protected and greased. With the exception of the friction surface on the clutch plate, do not clean the pressure plate. This will shorten the service life of the clutch considerably.

The pressure plate contact surface and clutch plate lining must make full contact with flywheel. Only then may the securing bolts be installed.

Only use compressed air to blow out the dual-mass flywheel.

The friction surfaces on the pressure plate and on the dual mass flywheel must be cleaned thoroughly (degreased).

Make sure centering sleeves for engine to transmission are installed in cylinder block, install if necessary.

If alignment sleeves are not installed, difficulty in shifting, clutch problems and possibly noises from the transmission (loose gear chatter) may develop.
