pulley bolt.

3. Remove the crankshaft pulley using VS1210/01 Remover.

4. Support the engine and remove the right-hand mounting/bracket, remove the

timing covers.

5. Turn the crankshaft in the normal direction of rotation into its timed position, and

lock by inserting the appropriate Flywheel Timing Pin into the ywheel datum hole.

The special shape of VS125/C6 and VS125/C8 allows their use around

components such as the starter motor etc which means such components are not

normally required to be removed. The VS1210/P9 Flywheel Locking Pin is used for

dual mass ywheel applications, it is held in place by attaching its retaining spring

to a suitable nearby xing point.

6. All of the 2.0HDi and 2.2HDi engines have an adjustable camshaft sprocket,

and uses the VS125/P4 Camshaft Locking Pin. The sprocket is xed with 3 securing

bolts through slotted holes in the sprocket. The VS125/P4 Camshaft Locking Pin

locates through a timing hole in the sprocket and its carrier, and into a datum hole in

the cylinder head to retain the camshaft in its timing position g.5.

7. Once the Locking Pin is inserted, the 3 securing bolts should be slackened to

nger-tight, this should be suf ciently tight to offer a slight resistance to the sprocket

turning, and this should be carried out prior to the old camshaft drive belt being

removed..

Engines equipped with an adjustable crankshaft gear.

1. With the ywheel and camshaft locking pins inserted and the engine is locked in

its correct timed position, the timing belt tensioner can be released and the old belt removed.

2. T he VS4820/P18 and VS4821 Crankshaft Gear Positioning Tools are used to correctly position the crankshaft

pulley during the tensioning process.

3. T he VS4820/P18 Crankshaft Gear Positioning Tool is inserted at the left side of the crankshaft key, as viewed,

g.6 prior to the new belt being tted.

4. After the timing belt has been tted, remove the VS4820/P18. The belt can now be tensioned to the correct

speci cation.

5. On engines variants that require the use of VS4821 Crankshaft Positioning Tool, the crankshaft gear is centralised

on the crankshaft key by inserting the VS4821 into position on both sides of the key.

6. After the timing belt is tted, remove the VS4821. The belt can now be tensioned to the correct speci cation.
