Injection Pump - Installation (0-88)

B Series Shop Manual
The injection pump drive gear has a tapered bore.
Orient the wide end of the taper toward the engine
(timing marks away). The drive gear for the Nip-
pondenso EP9 and the Bosch P7100 pump does not
have timing marks and must be positioned using the
tapered bore as a reference.
This table must be used to make sure of proper fuel
injection pump-to-engine timing. The critical parts list
(CPL) number from the engine data plate and the Control
Parts List Manual (Bulletin No. 3379133-20) must be used
to determine whether or not the engine is certified, and
if so, what year and regulating agency (EPA or CARB).
Given this information, use the table to determine which
letter on the fuel injection pump drive gear is aligned with
the camshaft gear.
Align the timing marks and set the gear into the housing.
No timing mark alignment is required for the Nippondenso
EP9, or Bosch Inline fuel pumps.
Locked Timed Injection Pump - Installation
(0-89)
Install the pump. Make sure the key doesn't fall into the
gear housing.
NOTE: The keyway in the shaft of new and reconditioned
pumps will be locked in a position corresponding to the
keyway in the drive gear when cylinder number 1 is at TDC.
If the Bosch, Stanadyne or CAV pump was not locked in
this position before removal and a timing tool, Part No.
3377259, is not available for the Bosch pump, refer to
installing an unlocked pump, procedures (0-91 and 0-92).
Refer to Section 5 for the Nippondenso EP9 and Bosch
inline timing procedure.
