Refitting and tensioning timing belt (page 2 of 2)

1. Before fitting the timing belt, ensure that camshaft timing is correct and that camshafts are secured by means of tools 1860985000. Ensure that pistons are aligned by checking the position of the pins on tools 1860992000 as described previously. Then fit the timing belt as described below:

1. Crankshaft drive gear
2. Coolant pump gear
3. Timing pulley
4. Belt tensioner fixed guide pulley

2. Position tool 1860987000 and adjust until automatic belt tension is set to maximum tension, i.e. with mobile reference (1) positioned as shown in the figure. Then tighten the nut retaining the tensioner to the mount. 3. Use reaction wrench 1860831000 to tighten the timing pulley on the intake side to the specified torque. Remove the tools positioned previously for camshaft timing adjustment and retention and then turn the crankshaft through two turns in its direction of rotation. 4. Loosen the tensioner retaining nut and align the mobile indicator on tensioner (1) with fixed reference (2). Then tighten the tensioner retaining nut to the specified torque. Turn the crankshaft through another two turns in its normal direction of rotation, and then replace engine timing adjustment tools described previously. Check that engine timing is correct.

Fit the remaining parts by reversing removal instructions.
