Section 5 – Procedures Non-Routine Maintenance
For the top of the 2nd and 3rd boom:
6.
The weight of the boom must be removed from
the rear wear pads to allow removal. Use the
boom control lever to lower the boom until the
carriage is on the floor or surface. This action
changes the load forces on the boom sections
so that there is clearance between the wear pads
and the outer boom.
7. Remove the screws, shims, and wear pads.
For easier installation, keep all parts removed
together as an assembly.
Install Slide Pads
NOTE
To keep the boom section centered, make sure
that the number of shims on the top wear pads
are approximately equal to the number on the
bottom wear pads. The number of shims on each
side of the boom must also be approximately
equal.
NOTE
Shims are 0.015, 0.030, and 0.060 inch thick.
Add or subtract shims as required to obtain a
clearance on the side between the middle and
outer boom secions of 0.59” maximum. When the
correct clearance is achieved, remove the screws
and apply red thread locking compound to the
threads of both the screws and wear pads.
1.
Clean installation area to remove any residual
grease. Ensure threads are free of grease, dirt.
2. With the carriage lowered to the floor, install the
top wear pads on the 2nd boom. Install the top
wear pad assemblies consisting of the wear pad,
shims and spacer, securing the assemblies by
installing screws on the front of the 2nd boom.
3.
Apply loctite 271 red and tighten the screws to 37
ft-lb.
4. Start the engine and use the joystick to raise the
carriage from the floor.
5.
Install the bottom wear pad assemblies consisting
of the wear pad, shims and spacer, securing the
assemblies by installing screws on the 2nd boom.
6. Apply loctite 271 red and tighten the screws to 37
ft-lb.
For installation of the side wear pads:
NOTE
Use a pry bar to hold the wear pads and shims in
position.
7. Clean installation area to remove any residual
grease. Ensure threads are free of grease, dirt.
8. Install the side wear pad assemblies consisting
of the wear pad, shims and spacer, securing the
assemblies by installing screws on the sides of
the 2nd boom.
9. Apply loctite 271 red and tighten the screws to
37 ft-lb. Ensure there is approximately an equal
number of shims under each wear pad.
10. Lubricate all wear pads with MPG-EP2 grease.
11. Extend and retract the boom and check for
smooth operation.
12. Install the rear cover on the outer boom.
