Injection pump, removal

1
Carefully clean the injection pump, pipes and the engine near
the pump. Remove the protection plate for the pump cou-
pling.
2
Undo the pressure pipe, fuel and lubrication pipes at the
pump and the control connections. Fit protective caps.
3
Undo the clamping screws on the pump coupling. Remove
the screws between the pump coupling and the carrier to the
pump. Press the pump coupling forwards onto the drive axle.
4
Unscrew the pump's securing screws and lift the pump out.
Ensure that the steel laminates do not get damaged.
Fitting and adjusting the
injection pump
Special tools: 999 3590, 998 9876, 999 6648
Note: Check that there is about 0.2-0.3 liters (0.2-0.3 quarts)
of engine oil in the pump and regulator before the injection
pump is fitted. Refilling takes place in the regulator housing.

Service procedures

The engine must always be washed prior to starting repairs.
Service procedures - fuel system
1
Remove the plug in the flywheel cover (16 mm hex socket
key) and fit rotating tool 999 3590. Remove the inspection
cover on the flywheel cover. Remove the inspection cover
on the camshaft at the cylinder block's rear end.
2
Rotate the engine with a ratchet handle to the compression
stroke for No. 1's cylinder (0° marking on the flywheel). The
camshaft's marking hole should be pointing up.
3
Turn back the flywheel in the opposite direction to the
engine's direction of rotation about 90° from the starting
point. Then turn it forward in the direction of rotation until
the correct number of degrees for the pump setting is imme-
diately behind the needle on the flywheel housing. See
"Workshop manual, Technical Data".
Note: Set the degree marking within the upper half of the tol-
erance area which is stated in the specifications.
The setting must be accurately carried out, and do not crank
the flywheel back against the direction of rotation to finely ad-
just the setting. If the flywheel has been cranked too far, the
setting procedure must be carried out again.
