• Use bolts with a 22 mm maximum thread length - a - to attach the (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 Top Dead Center (TDC) marking crankshaft from the cylinder block.






- 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 - 1 - back and 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).

- 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 => [ Power Take-Off Drive Chain Overview ] Power Take-Off Drive Chain Overview.

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

- Mount the chain tensioner together with the chain and the balance shaft sprocket.






- Lock the balance shaft in the TDC position with the (T40116).
