Fitting pump and checking advance on engine

Tools required: n° 1865091000 comprising probe stylus (C), mount (B) and centesimal dial gauge (A).
Pump must also bear label (E) glued to the top. Above this is the installation gap in mm preceded by wording in French (valeur de calage).

Fitting injection pump

• Move crankshaft to a position close to TDC.
• Fit injection pump (D) to its mount, aligning pump gear ridge with grooves inside pump drive shaft. Do not tighten nuts fastening pump to mount.
• Remove plastic cap from top pump cover
• Turn crankshaft against direction of rotation through about 20°.
• Tighten tool (B), with probe (C) and centesimal gauge (A), into threaded socket.

NOTE Probe (C) fits into a seat on the pump and not against the pump distributor or rotor.

The gap between the pump seat and the position of a distributor (rotor) dowel allows pump to be adjusted correctly in relation to the engine when the stylus touches the dowel as the pump is turned. The installation gap is indicated on label (E) on each pump.
