20A FUEL SYSTEM
To set a Bosch EPVE fuel injection pump with
locking screw
Caution: This procedure must be followed carefully
if the fuel injection pump:
• The fuel injection pump is new
• The pump performance is not correct
• The locking screw is released after the pump is
removed from the engine.
1 Hold the pump securely in a vice by the support
bracket.
2 Release the pump locking screw. Remove the
plug and washer from the rear of the pump and fit
the adaptor, MS.107, and a suitable dial gauge. Set
the dial gauge to indicate approximately 3,0 mm
(0.12 in).
3 Fit adaptor, PD.67-3 (C), for the timing tool,
MS.67B, to the drive shaft of the pump. Use the nut
for the drive gear, tightened finger tight only, to
retain the adaptor.
4 Fit the timing tool, MS.67B (D) to the adaptor
and fit adaptor PD.67B-1 to the timing tool.
PD.67B-1 is used to rotate the timing tool and the
shaft of the pump. To rotate the adaptor, it will be
necessary to make a suitable bar which uses the
three setscrews in the adaptor.
5 Set the injection advance device,if one is
fitted,operation 20A-06C
6 Ensure that the keyway in the drive shaft is
between outlet A and B for four cylinder engines (A)
or outlet A and F for six cylinder engines (B).
7 Check that the pump plunger is at its lowest
position and set the dial of the gauge to zero. There
will be no tension on the bar used to turn the pump
in this position.
8 Rotate the pump shaft slowly clockwise, from the
drive end, until the pointer on the dial gauge
indicates 1,0 mm (0.039 in) plunger lift. For engines
fitted with fuel pump code TL the plunger lift is 1,25
mm. Hold the shaft in this position and tighten
the pump locking screw.
