ROTATION REDUCTION GEAR WITHOUT
AN OIL LEVEL ROD
Checking the oil level.
While the machine is being used, the rotation reduction gear
oil heats up and increases its volume. While the machine
is being used, the rotation reduction gear oil heats up and
increases its volume. Therefore, check the level when the
temperature is close to the ambient temperature.
To check the oil level, proceed as follows:
- Place the machine on a at and level surface.
- Switch off the engine and remove the ignition key. Place
a “maintenance work in progress” sign in the cab.
- Raise the boom as far as possible and install the safety rod.
- Disassemble the guard protecting the rotating parts
(g.57/D Pos.“1”) by unscrewing the four sealing screws
(g.57/D Pos.“2”).
- Unscrew the level cap (g.58/D Pos.“2”) and ensure the
oil is level with the lower part f the hole.
- If there is insufcient oil, unscrew the ller cap (g.58/D
Pos.“1”) and top up until oil exits from the level cap
(g.58/D Pos.“2”).
- Reverse the procedure to reinstall all the parts.
Changing the oil in the rotation reduction gear
Replace the oil at the prescribed times as follows:
- Place the machine on a at and level surface.
- Switch off the engine and remove the ignition key.
Place a “maintenance work in progress” sign in the cab.
- Raise the boom as far as possible and install the safety rod.
- Disassemble the guard protecting the rotating parts
(g.57/D Pos.“1”) by unscrewing the four sealing screws
(g.57/D Pos.“2”).
- Place a container below the filter to collect the exhau-
sted oil during the replacement procedure.
- Remove the drain plug (fig.58/D Pos.“3”) and the level
cap (g. 58/D Pos. “2”) to speed up the operation.
- When you have finished draining the oil, re-screw the
drain plug (g.58/D Pos.“3”) and fasten tightly.
- Unscrew the ller cap (g.58/D Pos.“1”) and ll with appro-
ved oil until the oil exits from the level cap (g.58/D Pos.“2”).
- Reverse the procedure to reinstall all the parts.
- CAUTION:
Some vehicles have rotation reducers installed which
are “Maintenance free”. The level check and replace-
ment of the oil must never be performed.
