Bolt class 10.9, the steel bolt may be used again unlimited number of times.
Audi A4 through VIN 8K-9-066499, Audi A5 through VIN 8T-9-007999: Replace the aluminum bolts.
Audi A4 from VIN 8K-9-066500, Audi A5 from VIN 8T-9-008000: Aluminum bolts may be used two times.

⁽¹⁾	To prevent damaging the bolts when marking them, do not clamp them in a vise. Insert the bolt using a 14 mm socket with a 1/2 inch drive, which is inserted in to the vise, as illustrated.

See Fig 4

Audi A4 from VIN 8K-9-066500, Audi A5 from VIN 8T-9-008000: The aluminum bolts -2 through 11- may be used two times. Therefore, the bolts must be marked with two notches "X" made by a chisel after they have be used the first time -arrow-.

Bolts marked with an "X" may not be used again.

Procedure

NOTE:

Replace the bolts which are being tightened with an additional turn.

Replace self-locking nuts and bolts and seals, gaskets and o-rings.

In vehicles with manual transmissions, there is a needle bearing in the drive plate. Check if the needle bearing is inserted before installing. Remove needle bearing from drive plate and install. Refer to NEEDLE BEARING IN DRIVE PLATE, REPLACING .

Secure all hose connections with hose clamps of the same type as those equipped by the factory.

In order to be able to securely mount the air guide hoses on their connectors, spray the screws on the previously used clamps with a rust remover.

When installing, bring all cable ties back to same positions.

-- Install the engine supports and engine mount. Refer to OVERVIEW - SUBFRAME MOUNT .

-- Clean the threaded holes in the cylinder block for connecting the engine and transmission using a thread tap before installing the transmission.

-- The following preparations must be made before connecting the engine and transmission:

-- Insert the Clutch Module Assembly Aid T40169 in the transmission housing between the clutch module and the transmission housing as shown in the illustration.

The assembly aid must engage in the semicircular opening -1- and in the inspection hole -2-.

NOTE:

The inspection hole is only in one location on the circumference so rotate the clutch module as needed.

-- Install the assembly aid bolt into the hole on the transmission housing.

-- Insert the Clutch Module Transportation Lock T40170in the transmission housing from below and secure it on the flange shaft -1-.

-- Inspect the aluminum bolts used to connect the engine to the transmission to see if they can be used again and mark them, if necessary. Refer to ENGINE, INSTALLING information.

-- Position the transmission on the engine and tighten the bolts -1 through 11-.

-- Remove the Clutch Module Transportation Lock T40170 and Clutch Module Assembly Aid T40169.

NOTE:

The following procedure is necessary to assure that the clutch module contacts the drive plate evenly and does not get bent.
