Checking the Hub Oil Levels
Check each hub separately.
1 Park the machine on level ground with the OIL LEVEL
mark horizontal. There is a tolerance of 5 mm (0.2 in)
above or below the horizontal.
2 Engage the parking brake. Set the transmission to
neutral. Lower the attachments to the ground. Stop the
engine and remove the starter key.
3 Clean the area around the fill/level plug C. Remove the
plug. Oil should be level with the bottom of the hole. If
necessary, add the recommended oil. Clean the plug
before refitting it.
Changing the Hub Oil
The axle oil is used to lubricate the brake components and
cool the brake plates.
It is important that the oil is changed regularly as specified in
the service schedule - the lubricating properties of the oil will
reduce as a result of brake wear.
Consult your JCB distributor for advice if necessary.
Change the oil in each hub separately
1 Set the machine level, with the tyres just clear of the
ground. Manually rotate the wheels to bring the OIL
LEVEL mark on the hubs to the vertical position, with
the fill/level plugs C at the bottom.
2aPlace a container of suitable size beneath plug C to
catch the oil.
b Remove fill/level plugs C. Allow time for the oil to
drain out.
3aSet OIL LEVEL marks to the horizontal.
b Fill the hubs with recommended axle oil, through the
fill/level holes C. Oil should be level with the bottom
of the fill/level hole.
c Clean and refit fill/level plugs C.
