Fuel Injection Pump
IMPORTANT
If installing a new or recalibrated fuel
injection pump, locate and record the timing
index number located on the pump housing
boss on the engine side of the new or
recalibrated fuel injection pump
(Figure 7-22, (1)). This number will be used
to calculate and adjust the final fuel injection
timing.
Note: If either or both of the fuel injection
pumps do not have a timing index
number, note the injection pump ID
(example: XK42) on the injection pump
ID label.
To locate the timing index number for the engine
being serviced use the Timing Index Chart under
"FIE Specs" on the Yanmar Distributor Website
(http://distributor.yanmar.co.jp).
If additional assistance is needed in locating the
engine timing index number See To Locate an
Authorized Yanmar Industrial Engine Dealer or
Distributor: on page 2-4 and follow the instructions
to locate an authorized Yanmar industrial engine
dealer or distributor for assistance.
Note: Treat the timing index number as if it has
a decimal point (68 = 6.8).
