NOTE
The four individual fuel injector pumps are located at the side of the engine
between the push rods and are secured to the crankcase by a clamp (3) and nut
(6). The fuel pump is not repairable. Each fuel pump is timed individually using
the appropriate flywheel timing degree mark and when an existing or new fuel
pump is installed it is only necessary to refit the existing shim pack or a new pack
having the same thickness as the original. To retain the governor setting leave at
least one fuel pump in position.
1) Disconnect and plug or cap off the fuel inlet line (25, fig 6-3) at the engine
2) Using a pair of pliers, squeeze and rotate fuel line clamp (2) at pump end. Remove the fuel line
(1) from the fuel injector pump (5)
3) Turn the governor run/stop control lever (4) counter clockwise to the stop position.
CAUTION
If more than one fuel pump is being replaced take extreme care to ensure that
each shim pack is kept with its relevant pump. Do not remove or add shims to
this pack.
Do not remove the tappet stud (1, fig. 6-6)) under any
circumstances.
5) Remove the nut (6) and fuel pump clamp (3).
