OIL REPLACEMENT
WARNING! Oil change in the hydrostatic transmission
must be performed by skilled and qualified personnel.
- unscrew the caps of the radiator (1) and hydrostatic oil tank (2)
- remove the filter (5) and drain the oil into a container; to
perform this operation, proceed in the manner described in the
Filter Replacement Paragraph “EVERY 500 HOURS”
- disconnect pipe "F" located beneath the hydrostatic motor (4),
then drain the oil from the system into a container.
- once the oil has been completely drained, reconnect piping "F"
in its correct position
- install a new filter (5) for the hydrostatic transmission
- The system must be filed with specific hydraulic oil, filtered at
10-micron and supplied at a pressure of about 2.5 bar.
- For this purpose use a hand pump "M" as shown in the photo
(6). Pour the oil into the hydrostatic pump through pressure
inlet (fitting M16x2) until the tank is filled
-
close radiator cap (1)
- close cap (2) of the tank
- Remove the hand pump from the pressure connection and
close the cap
The system must be bled after filling; follow the instructions below:
-
closing the bonnet, get in the cab and start the engine
- leave the engine running for about 2 minutes
- switch off the engine
- wait 2 minutes to allow the air to bleed completely from the
system.
- open the bonnet and check that the oil level in the tank is
between the MIN and MAX marks. If not top up the level with
the specific oil (see paragraph FUEL AND LUBRICANTS in
this chapter).
Repeat this procedure until, having left the engine running for about 2 minutes, the oil level is within the MIN and MAX marks
on the tank.
