Power Take-Off Drive Chain
Power Take-Off Drive Chain
Special tools, testers and auxiliary items required
• Key (T40049)
• Locking Pin (T40071)
• Locating Pins (T40116)
Removing
• The transmission is removed.
• Engine oil drained.
CAUTION!
Risk of injury.
• The lock carrier must be installed and the torque support must be securely attached.
- Remove timing chain lower cover. Refer to => [ Lower Timing Chain Cover ] Lower Timing Chain Cover.
CAUTION!
Danger of damaging the drive chain because the bolt thread is too long.
• Use bolts with a 22 mm maximum thread length - a - to attach the key (T40049).
• If only longer bolts are available, then the bolt head must be installed in such a way so that thread length is still 22 mm only.
- Install the (T40049) with 2 bolts - arrows - on the back of the crankshaft.
- Remove the locking bolt - arrow - for the "TDC" marking from the upper section of the oil pan.
- Rotate the crankshaft in the direction of engine rotation to "TDC".
- Install the (T40069) in the hole and tighten to 20 Nm. Turn the crankshaft back slightly to completely center the bolt, if necessary.
- Press the chain tensioner guide rail in direction of - arrow - and secure chain tensioner using a (T40071).
CAUTION!
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 the bolts - 3 - and the balance shaft chain sprocket.
- Remove the bolts - 1 - and - 2 - and the chain tensioner with the chain.
Installing
• Tightening specifications, refer to => [ Timing Mechanism Drive Chain Assembly Overview ] Timing Mechanism Drive Chain Assembly Overview, or => [ Marking Locking Bolt - Tightening
Specification ] Oil Pan Upper and Lower Sections, Oil Pump and Oil Cooler Assembly Overview.
• Secure crankshaft - 1 - in "TDC" position using (T40069).
- Install the chain tensioner with the drive chain and the balance shaft chain sprocket.
- Lock the balance shaft in the "TDC" position with the (T40116).
• 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 the chain tensioner bolts.
- Loosely install the 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 the (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 the (T40116) from the balance shaft.
The rest of the 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.
