Injection Pump - Installation (0-88)
B Series Shop Manual
Remove the timing pin.
If the timing tooth is not aligned with the timing pin hole,
rotate the pump shaft until the timing tooth aligns.
Reverse the position of the pin so the slot of the pin will
fit over the timing tooth in the pump.
Install and secure the pin with the access plug.
Use a 50/50 mixture of clean engine oil and STP or
equivalent to lubricate the gear cover housing to ensure
the injection pump will slide into the housing easily.
