Step: 5
CAUTION
Use extreme care when removing the delivery valve
holder and delivery valve components. Keep all parts
together in the order in which they are removed from
the fuel injection pump.
Remove the delivery valve holder by carefully tipping the
holder outboard with one hand while using the other hand
to hold the spring, fill piece, and any shims from slipping
out of the holder. Place these as an assembly on a clean
surface out of the way.
Step: 6
Using a magnet, remove the two-piece delivery valve as-
sembly from the pump. Place these pieces on a clean
surface with the delivery valve holder.
Step: 7
CAUTION
Do not scratch the top of the plunger/barrel assembly
during gasket removal.
NOTE: The delivery valve gasket can be either bronze or
steel, or on new injection pumps, there is often no gasket.
If the gasket is bronze, use a pick to remove it from the top
of the pumping element; if the gasket is steel, use a pick
or a magnet. Discard the used delivery valve gasket.
