Intake Camshaft Balance Shaft: Installing

WARNING: This page is about a different car, the 2013 Volkswagen Jetta and 2012 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

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 .

-- 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 intake camshaft balance shaft.

-- Replace the O-ring -1- and lubricate it with engine oil.

-- Lubricate the bearing pin with engine oil and insert it. The alignment pin -arrow- for the bearing pin must engage in the hole in the cylinder block.

CAUTION:

Always replace the intermediate shaft sprocket. Otherwise the backlash will not adjust itself and it could result in engine damage. The new intermediate shaft sprocket has an anti-friction coating that wears off after a short period of use, which automatically adjusts the backlash.

-- Mark the tooth face on the intermediate sprocket -arrows-.

Tightening specifications, refer to Figure.

-- Check the marks on the intermediate shaft sprocket/balance shaft -arrow-.

NOTE:

Due to the ratio, the marks align only after every 7th turn.

-- Install the balance shaft timing chain. Refer to Installing .

The rest of the installation is basically a reverse of the removal sequence; when doing this, note the following:

-- Replace the coolant pump drive gear seal. Refer to COOLANT PUMP DRIVE GEAR SEAL, REPLACING .
