Exhaust Camshaft Balance Shaft

Exhaust Camshaft Balance Shaft

Special tools, testers and auxiliary items required

• Puller (T10394)

• Puller (T10055)

• Always replace the balance shaft after removing it.

Removing

- Remove the upper timing chain cover. Refer to => [ Upper Timing Chain Cover ] Upper Timing Chain Cover.

- Remove the lower timing chain cover, refer to the following:

• GTI and Eos, refer to => [ Lower Timing Chain Cover ] Lower Timing Chain Cover.

- Remove the camshaft timing chain. Refer to => [ Camshaft Timing Chain ] Camshaft Timing Chain.

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

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






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

- Install the half shell (T10394/1) from the puller (T10394).






- Install the puller (T10394) and push the sliding sleeve in the - direction of the arrow -.






- Install the puller (T10055) into the puller (T10394) and remove the balance shaft.






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 installed 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 pipe for the balance shaft - arrow -.






The pin - arrow - must engage in the groove.

• Press the pipe together slightly to position it in the installed position.

• Press the pipe into the crankcase and bend both halves one time to the inside.

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

- Lubricate the balance shaft bearing 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 pipe for the balance shaft must be installed again.

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

The rest of the installation is basically a reverse of the removal sequence.
