Injection Pump - Installation (0-
88)
Install the injection pump gasket. The
Nippondenso EP9 and the Bosch P7100 injection
pump use a sealing O-ring instead of a sealing
gasket. Make sure the O-ring is positioned
properly and not damaged. Lubricate with clean
engine oil.
NOTE
If the mounting flange o-ring has a colored
stripe, it can not be reused. Replace with a
new O-ring. Furthermore, do not lubricate the
new type O-ring. Instead, lubricate the
seating area of the gear housing.
Locate top dead center (TDC) for Cylinder
Number 1 by barring the engine while pushing in
on the engine timing pin until it engages.
The injection pump drive gear has a tapered bore.
Orient the wide end of the taper toward the
engine.
Set the gear into the front housing and engage
teeth of gear with teeth of camshaft gear.
NOTE
The P7100 fuel injection pump driveshaft has
a provision for a Woodruff key, however, it is
not required. Timing mark alignment is not
required for the P7100 drive gear.
