WARNING
You must carefully note the length of the bolts when
you install Yanmar recommended implements and
equipment behind the transmission case.
1. First, it is necessary to measure the thickness of
the parts. Then use bolts whose length includes
the extra measured thickness.
2. When the original part is removed and a
different part is installed, it is necessary to
measure difference in thickness of the two parts
and change the length of the bolts appropriately.
If you don’t use appropriate consideration of these
issues, you will damage the transmission case and
create a dangerous situation.
Reference
The bolt length “B” in the case must be 2.0 times the
diameter of “A”.
For casting metal cases, rear axles, etc.,
The bolt length “B” in the case must be 1.5 times the
diameter “A”.
(D): Transmission case
Cast metal cases
When you install part “a” behind the
transmission case, use bolts whose length
includes measurement “C”.
CAUTION
Do not try to adjust engine speed adjuster screw
(A) located on engine fuel injection pump. Any
accident or failure resulting from adjusting the
screw would not be covered by Yanmar's
guarantee.
Do not try to unseal and adjust engine fuel
injection pump (B). Any accident or failure
resulting from adjusting the pump would not be
covered by Yanmar's guarantee.
