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 12, (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).
