Setting the timing (continued).
NOTE:If necessary, you can slightly rotate the pinions (10)and (7)anti-clockwise in order to engage the belt.
The angular displacement value of the belt in relation to the pinions should not be more than half a tooth.
Remove tool [5].
Act on the tensioner roller (8)by its square «a», using tool [6]to check that the camshaft and injection
pump pinions can turn freely.
Position the belt tension instrument [7]on the belt at «b».
Using tool [6], act at «a»in the direction opposite to that of engine rotation, to obtain a tension value of
106 ± 2 SEEMunits.
Tighten screws (9), (5) and (6).
Remove tools [7], [2], [3]and [4].
Rotate the crankshaft 8 times
in the normal direction of rotation.
Peg the flywheel, using tool [2].
Peg the camshaft hub, using tool [4].
Peg the injection pump hub, using tool [3].
Slacken screws (9), (5)and (6).
Position the belt tension instrument [7]on the belt at «b».
Using tool [6], act at «a»in the direction opposite to that of engine rotation, to obtain a tension value of
42 ± 2 SEEMunits.

- Remove tools [7], [2], [3]and [4].
- Turn the crankshaft 2 times
in the normal direction of rotation.
- Peg the flywheel, using the peg [2].
- Visually check the peggings of the camshaft and injection pump.
ESSENTIAL: Visually check that the offsets between the holes of
the camshaft and injection pump hubs and the corresponding
pegging holes are not more than 1 mm. If necessary, recommence
the procedure for fitting the timing belt.
