Wear Pads
The wear pads support and guide the inner leg section. They
ensure that during extension and retraction the inner leg is
kept central and has a minimum amount of ‘float’.
Upper wear pads
A
(4 off) are fitted to the top of the inner
leg as shown. The upper pads are available in 3 sizes and
are colour coded; 5mm (green); 6mm (red) and 7mm (blue).
Lower wear pads comprise adjustable pads
B
(2 off) and
fixed pads
C
(2 off).
When pads
A
and
C
have worn to a minimum thickness of
0.5 mm (0.020 in.) they must be replaced with new ones. To
replace the pads, the stabiliser inner leg must be removed
(contact your JCB Distributor).
It is important to note that lower pads
C
are designed to
take most of the ‘loading’ during stabiliser leg operation, as
a consequence these pads must be checked regularly for
wear.
When replacing pads, it is recommended that the complete
lower set of pads are replaced (items
B
and
C
). The top
pads should be inspected and replaced as required.
Wear Pad Adjustment
Note: It is very important that the wear pads are adjusted
at the correct service intervals, as the inner leg could
contact the outer leg and scoring could occur. Scoring
will dramatically reduce wear pad life.
Remove and clean away all debris that may have built up in
stabiliser cavities.
As a guide, there should be approximately 1mm (0.039 in.)
float between the stabiliser inner and outer leg.
Before adjusting the clearance make sure that the leg is
raised clear of the ground but not fully retracted.
To adjust the clearance, screw pad
B
fully in until it just
touches the inner leg and then back the pad off by one
quarter of a turn.
Note:
Over-tightening the adjustable pad
B
will lock the pad
in position, it will not be possible to back the pad off. If this
should happen, operate the stabiliser leg as normal but be
aware that pads
B
and
C
will wear more rapidly.
