4.4 HST oil

4.4.1 General

The HST casing is a sealed unit, which normally
not need any service. Oil filling is
recommended only if any of the cases or both
cases below are valid:
• There is a visible oil leakage.
• Drive problems.

4.4.2 Oil filling

Note!
It may be difficult to remove the entire
oil plug intact. It is recommended to
have a new plug available before
starting the oil filling.
1. Lift the machine.
2. Remove the oil plug.
The oil plug also works as a ventilation valve.
The oil plug consists of rubber and fits rather
hard in the housing hole.
Use a long pointed chisel to work up the
plug. Eventually, loosen the HST in the frame
and lower it for better access.
3. Check the oil level. Use a suitably bent steel
wire or similar.
The level shall reach up to just under the
lower part of the plug.
4. If neccesary, top up with new oil.
Use oil SAE 10W-40 or SAE 5W-50.
Elongate the discharge of an oil can with a
plastic hose of suitable length and diameter.
Put the other end into the HST oil hole and
pump until the oil flows over.
5. Fit a new oil plug and assemble in reverse
order.
