ENGINE TIMING 17A
To check the timing of the
- Bosch EPVE fuel injection pump17A-03
Special tools:
Timing gauge adaptor, MS.107
Spanner for flange nuts of fuel injection pump,
PD.239
Note: The procedure given below is suitable for
engines fitted with a Bosch EPVE fuel injection
pump and have a static timing of 10° or more.
1 Set the piston of number 1 cylinder to TDC on
the compression stroke, operation 17A-01. It is not
necessary to fit a temporary pointer
(17A-01/paragraph 1). Instead, the dial of the dial
test indicator (A1) should be set at zero when the
clockwise movement of the pointer stops
(17A-01/paragraph 7).
2 Remove the high-pressure pipes from the fuel
injection pump. Ensure that a spanner is used to
prevent movement of the pump outlets when the
high-pressure pipes are removed or fitted.
3 Remove the plug and washer from the rear of
the fuel pump and fit the adaptor, number MS.107,
and a suitable dial gauge (A2). Set the dial gauge to
indicate approximately 3,0 mm.
4 Slowly rotate the crankshaft, counter-clockwise
from the front of the engine, until the dial gauge
indicates that the plunger of the fuel injection pump
is at the bottom of its stroke. Set the dial to zero.
5 Slowly rotate the crankshaft clockwise until the
dial gauge on the valve stem indicates the correct
position of the piston before TDC, see data and
dimensions. The timing of the fuel injection pump is
correct if the dial gauge on the pump plunger
indicates 1,0 mm (0.039 in).
6 If the timing is not correct, disconnect the
remainder of the pipes of the fuel injection pump
and loosen the setscrew of support bracket for the
pump.
7 To correct the timing, hold the fuel injection
pump and release the flange nuts; if a compressor
is fitted, it will be necessary to use tool number
PD.239 to release the flange nuts nearest the
cylinder block. If the gauge on the pump plunger
indicates more than 1,0 mm (0.039 in), rotate the
fuel pump counter-clockwise, from the rear of the
fuel pump, until the gauge indication is 1,0 mm
(0.039 in). If the gauge indication is less than
1,0 mm (0.039 in), rotate the fuel pump clockwise
until the gauge indication is 1,0 mm (0.039 in).
Tighten the flange nuts and the setscrew of the
support bracket for the pump.
