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].
