- The aluminum bolts -2 through 10- 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-.
- Do not used bolts marked with an "X" again.
Procedure
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 S-Tronic transmission 0B5, there is a needle bearing in the drive plate. Check if the needle bearing is inserted before installing. Needle bearing, removing from and installing on drive plate. Refer to NEEDLE BEARING ON DRIVE PLATE .
The hose connections as well as the air guide pipes and hoses must be free of oil and grease before installing.
Secure all hose connections with hose clamps of the same type as those equipped by the factory.
To mount the air guide hoses on their connectors securely, spray the bolts on the used clamps with rust remover before installing.
When installing, bring all cable ties back to same positions.
-- Install the engine supports and engine mount. Refer to SUBFRAME MOUNT OVERVIEW .
-- When joining the engine and subframe, hold the ATF lines in their installation position.
-- 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 T40169 into the transmission housing and clutch module from underneath as illustrated.
- The assembly aid must engage in the semicircular opening -1- and in the inspection hole -2-.
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.
-- Install the T40170 into the transmission housing and the clutch module from underneath and secure it to the flange shaft -1-.
-- Check if the alignment sleeves -A- for centering the engine/transmission are in the cylinder block and insert them if they are not.
-- 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 ENGINE, INSTALLING .
-- Attach the transmission to the engine and the tighten the bolts -1 and 6 through 10-.
-- Remove the T40170 and T40169.
The following procedure is necessary to assure that the clutch module contacts the drive plate evenly and does not get bent.
-- Press the clutch module -2- slightly against the drive plate -3- using a pry bar -1- in -arrow-.
-- Secure the clutch module to the drive plate as follows:
Tighten the bolt with the V.A.G 1332/14.
-- Install the first bolt -arrow- and tighten by hand (2 Nm).
-- Insert the T40058 guide pins as follows:
- The large diameter -arrow 1- faces the engine.
- The small diameter -arrow 2- faces the adapter.
-- Rotate the crankshaft 180° further in direction of engine rotation -arrow- using the T40058 and ring wrench.
-- Tighten the bolts that are accessible in this position to the tightening specifications. Refer to Specifications .
-- Turn the crankshaft 60° further and tighten the remaining 5 bolts to the tightening specification. Refer to Specifications .
-- Install the power steering hydraulic oil lines. Refer to POWER STEERING HYDRAULICS .
-- Install the coolant recirculation pump. Refer to COOLANT RECIRCULATION PUMP -V50- (WATER PUMP -V36-) LOCATION, ACTIVATION AND FUNCTION .
-- Install ATF lines. Refer to Removal and Installation .
-- Install the left and right drive axles on the transmission flange shafts. Refer to OVERVIEW - DRIVE AXLE .
-- Install the catalytic converters: for the left one, refer to LEFT CATALYTIC CONVERTER and for the right one, refer to RIGHT CATALYTIC CONVERTER .
-- Next, raise engine/transmission subassembly high enough using VAS 6131 A until dimension -a- is reached between subframe and body.
- -a- = minimum 100 mm
-- Install the selector lever cable and adjust if necessary. Refer to Removal and Installation .
-- Continue raising the engine/transmission subassembly using the VAS 6131 A.
-- Align the subframe and transmission carrier using the marks made on the longitudinal members during removal.
-- Tighten the subframe bolts only to the tightening specifications, do not tighten them further (tighten the bolts only after axle alignment). Refer to OVERVIEW - SUBFRAME .
Risk of accident due to loose connections.
- If the bolts in the subframe are not tightened to final torque, vehicle must not be driven.
-- Tighten the tunnel crossmember bolts -arrow-. Refer to Removal and Installation .
Install in reverse order of removal paying attention to the following:
