Setting the timing (continued).
NOTE:
If necessary, you can slightly rotate the pinions (10)and (7)anticlockwise 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 SEEM units.
Tighten screws
(9), (5)and (6).
Remove tools
[7], [2], [3]and[4].
Rotate the crankshaft
8 timesin 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».
