LOAD SENSING PIN REMOVAL AND
INSTALLATION
1.
Place the machine on a firm, level surface.
NOTE:
Replacing the load sensing pin requires the boom sensors
be re-calibrated. Make sure the machine is in an area
where this can be accomplished after installation of the
new pin.
2.
Swing the engine tray out to gain access to the sensing
pin and retaining pin.
NOTE:
The lift cylinder weighs 787 lbs. (357 kg.)
3.
Run a nylon strap capable of supporting the weight of
the lift cylinder around the bottom of the cylinder. Lift
up on the strap to relieve the weight of the lift cylinder
on the load sensing pin.
4.
Loosen and remove the bolt that secures the retaining
pin and remove the retaining pin.
5.
Disconnect the wiring harness from the strain relief con-
nector at the opposite side of the load sensing pin.
6.
Use the Load Pin Removal Tool (JLG P/N 4846765) to pre-
vent the pin from being damaged, and use a hammer to
remove the pin. To make the tool refer to Figure 4-12.,
Load Pin Removal Tool, JLG P/N 4846765. If the Load Pin
Removal Tool is not available, use an arbor of the proper
size (as shown below). If excessive force is necessary to
move the pin, it may be necessary to carefully activate
lift using the auxiliary power switch to relieve lift cylin-
der weight from the load sensing pin.
7.
When installing a new pin, make sure all of the holes in
the turntable and lift cylinder are aligned. If the new
load sensing pin does not push 1/2 to 3/4 of the way in
by hand, remove the pin and align the holes better. Also
make sure the pin is installed with the strain relief con-
nector opposing the pin orientation bar as shown. Refer
to Pivot Pin Installation.
8.
Using an oak block, carefully tap the pin until it is fully
installed. Secure the pin in place with the retaining pin
and retaining pin bolt.
DO NOT TAP ON THE CENTER OF THE PIVOT PIN.
9.
Connect the wiring harness to the strain relief connector
and re-calibrate the boom sensors.
