NOTE:
The MP4 fuel injection pumps (4TNV98
model engines) are fastened to the gear case with
four (4) studs and nuts.
24.
Remove the fuel injection pump
(Figure 7-17,
(1))
. For purposes of future injection timing
purposes, record the fuel injection pump timing
index number located on the boss on the
engine side (back) of the of the fuel injection
pump
(Figure 7-18, (1))
.
Figure 7-18
CAUTION
Do not rotate the crankshaft with the injection
pump removed.
25.
If the fuel injection pump requires servicing, it
must be sent to an authorized Yanmar FIE
repair facility for repair and calibration, or
replaced with a new fuel injection pump.
CAUTION
NEVER remove or attempt to remove the
tamper-proof devices from the full-load fuel
adjusting screw or the high-speed throttle limit
screw on the fuel injection pump and governor
assembly. These adjustments have been made
at the factory to meet all applicable emissions
regulations and then sealed.
NEVER attempt to make any adjustments to
these sealed adjustment screws. If adjustments
are required, they can be made only by a
qualified fuel injection shop that will ensure the
injection pump continues to meet all applicable
emissions regulations and then replace the
tamper-proof seals.
Tampering with or removing these devices may
void the “Yanmar Limited Warranty.”
Installation of 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 7-19, (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.
