Fuel Pump Timing lndex Stamping
Identification
The timing index numbers stamped on the original
fuel pump hydraulic head are needed for the engine
technician to set fuel injection timing.
Replacement hydraulic heads do not have the
necessary timing index numbers stamped on the
engine side boss like the original fuel pumps. The
timing index numbers are needed to properly set
injection timing when reinstalling the fuel injection
pump.
Upon completion of fuel pump repairs when the
hydraulic head
is replaced the correct timing index
number must be manually stamped
(Figure 6-14, (1)) onto the boss on the engine side
of the hydraulic head.
