Removal
1. Remove the timing belt.
2. Remove the 8mm mounting bolts securing the fuel pump pulley from turning.
3. On some models, the pulley may be equipped with a puller, which consists of a plate bolted to the pulley. On models without a puller, the pulley can be removed from the shaft using the plate and two bolts that are screwed into holes provided in the pulley.
4. Secure the high pressure fuel pump shaft from turning using a special tool.
5. On models with a built-in puller, loosen the pulley retaining nut and remove the pulley and woodruff key from the pump shaft.
6. On models without a built-in puller, partially loosen the pulley retaining nut, install the improvised puller, and tighten the two bolts until the pulley is removed from the pump shaft. Remove the pulley and woodruff key.
Installation
1. Install the woodruff key into the groove on the pump shaft.
2. If the built-in puller was removed from the pulley, screw the two puller bolts into the pulley.
3. Install the pulley and secure it with the nut, tightening it to the required torque. At the same time, hold the pulley from turning.
4. Check that the mounting bolts and rod are installed in the holes of the camshaft pulleys, high pressure fuel pump and flywheel.
5. Install the timing belt onto the high pressure fuel pump pulley so that the marks made on the belt and pulley before removal are aligned.
6. Adjust the timing belt tension.
7. Install the timing belt covers.
Coolant pump pulley
The coolant pump pulley is pressed onto the pump shaft and cannot be removed from the pump separately.
