- Move piston of first cylinder to a position close to TDC.
- Fit injection pump (D) to its mount. Ensure ridge on pump
gear is aligned with inner pump drive shaft splines but do
not tighten nuts retaining pump to mount fully.
- Remove aluminium cap with fitting for socket wrench from
fitting on top of pump.
- Turn crankshaft against direction of rotation through about
20°.

threaded seat on top of the pump.

N OTE In this position, probe (C) will come into contact with
a seat in the pump and not against pump distributor
(or rotor).
The distance between pump seat and the position of a
distributor (or rotor) drive dowel is used to achieve
correct pump setting on engine: when pump is tur­
ned, probe touches drive dowel. The above fitting di­
stance is indicated on label (E) attached to each
pump.
A. Dial gauge.
B. Tool 1865091000 for checking advance.
C. Probe plunger.
D. Injection pump.
