Power Take-Off Drive Chain

Power Take-Off Drive Chain

Special tools, testers and auxiliary items required

• Key (T40049)

• Locking Pin (T40071)

• 8 mm diameter drill bit

Removing

• Transmission removed.

- Remove timing chain lower cover. Refer to => [ Lower Timing Chain Cover ] Lower Timing Chain Cover.




The drive chain could be destroyed.

• Place a washer under the bolt heads to prevent the bolts from pinching the drive chain.

- Install Key (T40049) at the rear of the crankshaft using two old drive plate bolts - arrows -.





- Remove locking bolt - arrow - for the "TDC" marking from the cylinder block.





- Rotate crankshaft in direction of engine rotation to "TDC".

• The crankshaft locating hole is difficult to find when the engine is installed.

• Rotate the engine until the small notch - 1 - on the vibration damper aligns at the left of the housing separation point - 2 - between the cylinder block and the guide frame. This makes it easier to install the Locking Pin (T40069).





• The marking on the vibration damper is only there to help. The exact "TDC" location is only reached by installing the Locking Pin (T40069).

- Install the Locking Pin (T40069) in the hole and tighten to 20 Nm. Turn the crankshaft back slightly to completely center the bolt, if necessary.





- Press chain tensioner guide rail in direction of - arrow - and secure chain tensioner using a Locking Pin (T40071).






Risk of destroying due to reversed running direction on a used drive chain.

• Mark the drive chain running direction with arrows using paint for installation later. Do not mark the chain using a punch, notch or similar.

- Remove bolts - 3 - and the balance shaft chain sprocket.

- Remove bolts - 1 - and - 2 - and the chain tensioner with the drive chain.

Installing

• Tightening specifications => [ Timing Mechanism Drive Chain Assembly Overview ] Timing Mechanism Drive Chain Assembly Overview, => [ marking locking bolt - tightening
specification ] Crankshaft Assembly Overview.

• Secure crankshaft - 1 - in "TDC" position using Locking Pin (T40069).





- Install the chain tensioner with the drive chain and balance shaft chain sprocket.

- To protect against cuts, wrap the point and the cutting edges on an 8 mm diameter drill bit with insulating tape.

- Secure the balance shaft in the "TDC" position using an 8 mm diameter drill bit - 2 -.





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

- Tighten chain tensioner bolts.

- Loosely install chain sprocket bolts - 1 - and - 3 -.

• It must still be possible to rotate the chain sprocket on the balance shaft and it must not tip.

- Remove Locking Pin (T40071) to release the chain tensioner.

- Press against the chain tensioner guide rail - arrow - using a screwdriver while tightening the chain sprocket bolts - 1 - and - 3 -.

- Remove drill bit - 2 - from the balance shaft.

The rest of installation is in reverse order of removal, note the following:

- Install timing chain lower cover. Refer to => [ Lower Timing Chain Cover ] Lower Timing Chain Cover.

- Fill engine oil and check the oil level. Refer to => [ Engine Oil, Checking Level ] Testing and Inspection.
