C. Fitting timing gear casing
The position of the timing gear casing and cover is deter-
mined by two tension pins. Therefore centring should not be
undertaken in connection with fitting. However, the tooth
backlash between the different gears should be checked.
Casing and covers that are delivered as spare parts also have
holes for the tension pins already machined.
1. Fit the casing with a new gasket against the cylinder block.
Drive in the tension pins with drift 9025 98700. Tighten bolts
and nuts.
2. Fit the injection pump together with gear wheel (if re-
moved).
3. Lubricate the camshaft bearings and insert the shaft in the
cylinder block. Release the pushrods and tappets if they have
been suspended.

4. Fit the idler gear with shaft stud and ensure that the mark-
ings are in the correct position. Fit the washer and tighten the
bolts to the correct torque.
