Drive Chain For Oil Pump and Balance Shaft, Removing and Installing

Drive chain for oil pump and balance shaft, removing and installing





Special tools, testers and auxiliary items required
^ Old oil collecting and extracting device V.A.G 1782
^ Adapter T40049
^ Locking pin T40069
^ Securing pin T40071
^ Drill bit dia. 8 mm

Removing
- Remove transmission.
- Vehicles with manual transmission: Remove clutch pressure plate and dual mass flywheel.
- Vehicles with automatic transmission: Remove drive plate.

Note:
^ After removing transmission, the engine is supported by engine support bridge 10-222 A and the torque support stop is loosened.

CAUTION! For the further sequence of work, it must be made sure that the lock carrier is installed.

- To remove transmission, remove attached engine support bridge 10-222 A from engine.





- Tighten torque support stop to 28 Nm - arrows -.
- Remove left and right timing chain covers.
- Place old oil collecting and extracting device V.A.G 1782 under engine.
- Drain engine oil.
- Remove lower timing chain cover.

CAUTION! Place a washer under the bolt heads, to prevent the chain from being pinched by the bolts.





- Install key T40049 at rear on crankshaft using 2 old bolts - arrows - for dual-mass flywheel.

Vehicles with manual transmission:





- Unfasten left and right stabilizer bar mountings - 1 - and - 2 -.
- Pivot stabilizer bar downward.

All:





- Remove sealing plug - arrow - from cylinder block.

CAUTION! Do not turn crankshaft while touching TDC hole with finger - Risk of injury.

- Rotate crankshaft in direction of engine rotation to TDC of ignition timing.





- Install crankshaft holder T40069 into hole to 20 Nm, if necessary rotate crankshaft very slightly back and forth to completely center holder.
- Mark running direction of drive chain for oil pump and balance shaft with paint.





- Press chain tensioner guide rail in direction of - arrow - and secure chain tensioner with securing pin T40071.
- Remove bolts - 1 through 3 - and remove chain tensioner, balance shaft sprocket and chain.

Installing





^ Secure crankshaft - 1 - in TDC position using crankshaft holder T40069.





- Mount chain tensioner with chain and balance shaft sprocket.
- To protect against cuts, wrap point and cutting edges of with insulating tape.
- Secure balance shaft with 8 mm dia. drill bit - 1 - in TDC position.

^ The slots in balance shaft sprocket must be at middle position in relation to threaded holes of balance shaft. If necessary, adjust chain by one tooth.

- Tighten chain tensioner bolts.
- Loosely install bolts - 2 - for sprocket.

^ Chain sprocket must still be able to be rotated on balance shaft and must not tip.

- Pull out securing pin T40071 to release chain tensioner.
- Press against chain tensioner guide rail - arrow - with screwdriver and simultaneously fasten bolts - 2 - for sprocket.
- Pull drill - 1 - out of balance shaft.

Further installation is in reverse order of removal, note the following:
- Install lower timing chain cover.
- Install oil filter housing.
- Install left and right timing chain covers.
- Install crankshaft seal, timing chain side.
- Vehicles with manual transmission: Install dual mass flywheel and clutch pressure plate.
- Vehicles with automatic transmission: Install drive plate.
- Install transmission.
- Install stabilizer bar.
- Add engine oil and check oil level.
