Removing

- Remove the balance shaft timing chain. Refer to => [ Balance Shaft Timing Chain ] Balance Shaft Timing Chain.

- Remove the exhaust camshaft balance shaft bolt - 1 - and the balance shaft.






If the balance shaft cannot be removed by hand, use the puller (T10394).

Installing

• Because of the small clearance between the balance shaft and cylinder block, the balance shaft may need to be cooled in order to install it. Check if the balance shaft can be inserted into the cylinder block without forcing it in. If it cannot, the balance shaft must be cooled before installing it.

• Tightening specifications, refer to => [ Balance Shaft Timing Chain Overview ] Balance Shaft Timing Chain Overview.

- Check the installed position of the balance shaft tube - arrow -.






The tab - arrow - must be at the top. This prevents it from turning.

• Squeeze the tube together slightly to position it in the installed position. Insert the spanner wrench (3212) into the two holes at the front of the tube, then insert the tube using the spanner wrench (3212).

- Place the new balance shaft in a freezer for 30 minutes or spray it with commercially available cooling spray.

- Lubricate the balance shaft bearings with engine oil.

- Install the exhaust camshaft balance shaft.

- Before tightening the bolt - 1 - make sure the balance shaft lies level with the crankshaft.






• If the balance shaft is not level, then the balance shaft tube must be installed again.

- Install the balance shaft timing chain. Refer to => [ Installing ] Balance Shaft Timing Chain.

Further installation is in the reverse order of removal.
