DANGER: Support of the boom is essential to avoid the possibility of
injury or death should the boom fall. Use suitable blocking and
lifting devices when removing heavy machine components.
4. Place blocks or other means of support under the front and rear
corners of the outrigger frame. Make sure supports are adequate to
support the weight of the outrigger; the outrigger weighs approximately
2585 pounds.
5. Disconnect the wiring harness (Item 4) from the differential pressure
switch (Item 2) from both cylinders. Remove the ties (Item 3) securing
pressure switch wires to wiring harness or hydraulic hoses.
6. Loosen and remove two (2) hydraulic hoses (Item 6) from elbows
(Item 5) on both outrigger cylinders (Item 1). Tag hoses and fittings.
Bleed any remaining oil into a suitable container.
7. Remove the nut (Item 18), lockwasher (Item 19), and capscrew
(Item 20) from the shaft assembly (Item 17).
8. Remove all ties around hydraulic hoses and wiring harness.
9. Remove the capscrew (Item 10), lockwasher (Item 11), and double
tube clamp (Item 12) securing the hydraulic tubes to the clamp plate
(Item 13) on each side of the machine.
10. Remove four (4) each nuts (Item 16), starwashers (Item 15), jam nuts
(Item 14), and capscrews (Item 9) securing each of the clamp plates
and the outrigger assembly to the axle. Remove the clamp plates.
11. Remove the wiring harness and hoses from outrigger and secure them
to the main frame.
12. Start the engine and slowly back the machine away from the outrigger.
(Ref. Fig. 10-2) The following procedure describes installation of the
outrigger.
1. If the bushing and shaft assembly were removed,
a. Install the shaft assembly (Item 17) on the bushing, making sure
the port for a grease fitting is on the rights side of the machine.
b. Install a grease fitting (Item 21) on the shaft assembly. Torque the
grease fitting to 1.5–3 turns past finger tight. Install a grease fitting
cover (Item 8) on the grease fitting.
2. With the boom raised and fully supported, use sling(s), crane or other
suitable means of support to position the outrigger until it can be slid
onto the shaft assembly (Item 17).
3. Temporarily install a capscrew (Item 20) into the orifice in the shaft
assembly (Item 17). Measure the gap between the outrigger assembly
and the support plate boss on the main frame.
4. Remove the capscrew and outrigger assembly.
