Removing
1. Timing drive components are shown in the illustrations above.
2. Remove the drive belt.
3. Remove the timing belt and camshaft gears
4. Remove the rear timing belt cover
5. Turn out two fixing bolts and remove an oil pipeline of the vacuum pump
6. Remove the vacuum pump.
7. Block the crankshaft and unscrew the central bolt of its pulley (refer to accompanying illustration).
8. Remove the spacer and use a puller to dismantle the crankshaft pulley.
9. Turn out 14 bolts of fastening of a cover of cogwheels of a drive of GRM.
10. Measure the axial clearance of the intermediate gear and, if necessary, replace its thrust plate, shaft, or the gear itself.
11. Remove the oil pump drive gear with a puller.
12. Turn out two bolts, remove a persistent plate, a cogwheel and its axis.
13. Block the gear wheel of the injection pump, give the nut of its fastening and remove the gear wheel.
Note. Screw the puller bolts no more than 8 mm.
14. Dismantle the gear wheel of the injection pump and timing drive.
Installation
1. Installation is carried out in the reverse order.
2. To install the intermediate gear, turn the drive gear of the injection pump so that the mark «3» on the gear wheel of the crankshaft is aligned with the mark «4» on the driving gear wheel of the injection pump. Then engage the gears (refer to accompanying illustration).
