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.
Aluminum cases
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”.
