Safety Precautions
NOTICE
Do not rotate the crankshaft with the injection pump
removed.
NOTICE
Keep the piston pin parts, piston assemblies, and
connecting rod assemblies together to be returned
to the same position during the reassembly
process. Label the parts using an appropriate
method.
NOTICE
Do not allow the honing tool to operate in one
position for any length of time. Damage to the
cylinder wall will occur. Keep the tool in constant
up-and-down motion.
NOTICE
Any part which is found defective as a result of
inspection or any part whose measured value does
not satisfy the standard or limit must be replaced.
NOTICE
Any part determined to not meet the service
standard or limit before the next service, as
determined from the state of current rate of wear,
should be replaced even though the part currently
meets the service standard limit.
NOTICE
• 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.”
NOTICE
The fuel return line is a one-piece assembly. Use
care not to bend or twist the fuel return line.
NOTICE
Never use a steel wire brush to clean fuel injectors.
Damage to the nozzle and other components is
likely to result.
