ENGINE DISASSEMBLY
16. Remove the fuel injectors, dust seals and sealing
washers from the cylinder head using a 27mm deep
socket.
17. Remove the glow plugs.
18. Remove
the crankcase breather hose and rocker arm
cover.
19. Remove
the engine mounted fuel filter and fuel line to
the injection pump. (Note the arrangement of the seal-
ing washers on the banjo bolts at fuel filter and the injec-
tion pump.)
20. Remove the injection pump. Scribe the mating marks
on the pump body flange and the timing gear case before
a. Remove the cover and the locknuts.
h. Loosen the two injection pump holddown nuts.
Do not
remove entirely. The holddown nut on the engine side
of the pump can be loosened by using a 114" universal
socket and extension with ratchet.
c. Remove the nut and lockwasher from the injection
pump shaft.
NOTE: Take care not to drop the nut and the washer
into the timing gear case.
d. Place the keyway on the injection pump shaft in the
12:00 position with the aid of the front crankshaft
pulley bolt before attempting to remove the
injection pump.
e. With the use
of extractor Mazda tool #49 SE 01 157
apply sufficient pressure to loosen the pump from the
keyed gear. The loose holddown nuts will prevent the
pump from falling from the engine.
f. Once loosened, remove the holddown nuts and wash-
ers and carefully withdraw the pump from the drive
gear and engine so as to avoid losing the injection
pump drive key inside the timing case.
NOTE: If an extractor is not available, replace the nut
on the injection pump shaft loosely and with a nylon
drift and hammer gently
tap the injection pump shaft to
dislodge it from the keyed drive gear.
Injection Pump
If the injection pump requires servicing, it should be sent to
an injection service shop that can properly service a
Kiki-
Zexel-Distributer type injection pump.
If the injection pump does not require servicing, it should be
wiped clean, covered and set aside until reassembly.
Adjustments to timing
if needed can be performed after
assembly.
