1. Unscrew the bolts (1a) and remove the water pump/balancer shaft drive chain hydraulic tensioner.

1. Undo the bolts (1a) and remove the chain tensioner pads (1b).2. Remove the water pump/balancing shafts drive chain.3. Remove the water pump/balancing shafts drive chain pulley.

1. Using a suitable tool for counter-torque, undo the water pump drive gear fixing bolts.2. Remove the water pump drive gear.

1. Fit the tool (1a) using the bolt (1b) for securing it (it is the bolt fixing the counter-balance shaft flange).

Tool	Description	Function	Validity
2000000600	Counter-torque	Loosen/ tighten bolts securing the counter-balance shaft drive pulley	1.9 JTS2.2 JTS

2. Undo the bolt (2a) and remove the inlet side counter-balance shaft drive pulley (2b).

This pulley has the words "INTAKE" and "GREEN" stamped on it so that it is correctly refitted.

- Carry out the same operations for the exhaust side counter-balance shaft drive pulley.

This pulley has the words "EXHAUST" and "WHITE" stamped on it so that it is correctly refitted.

Refitting ( Removing

) 1. Position the inlet side counter-balance shaft drive pulley (1a) in its housing and secure it tightening the bolt (1b) to the recommended torque.

Water pump drive pulley	Bolt	M6	(water pump side) 0.8	1.9 JTS2.2 JTS

- Place the water pump/balancing shafts drive chain pulley in its housing.

Take care over the fitting position.

1. Place the water pump/balancing shafts drive chain in its housing.

The copper mesh (a) should be aligned with the arrow stamped on the inlet side balancing shaft drive pulley; the silver mesh (b) should be aligned with the reference C-R stamped on the drive pulley; the silver mesh (c) should be aligned with the arrow stamped on the exhaust side balancing shaft drive pulley.

2. Place the chain tensioner pads (2a) in their housing and secure it by tightening the bolts (2b) to the recommended torque.
