NOTE
A forklift can also be used by trained, experienced personnel to support the pump
and manifold assembly.
3. Remove the bolts attaching the hydraulic pump to the electric motor.
4. Slide the motor away from the pump and manifold assembly to expose the flexible
coupling.
NOTE
If additional clearance is required to separate the motor and pump, the electrical
panel can be removed from the end of the frame. Remove the hex nuts from the
studs holding the electrical panel. Move the panel 4-8 inches away from the frame.
It should not be necessary to disconnect the motor lead wires. However, the wire
ties holding the electrical control harness to the top pan will need to be removed in
order to move the electrical panel.
5. Remove the failed flexible coupling.
6. Wipe any residue, dirt or oil from the coupling halves on both the motor shaft, and the
pump shaft. Avoid damaging the shaft seal on the pump.
NOTE
Additional clearance and access to the motor and pump coupling can be achieved
by moving the pump and manifold assembly to the right. The pump suction hose
will limit movement to approximately one inch. It should not be necessary to
disconnect any hydraulic hoses.
7. Inspect the metal splines on the coupling halves for damage. If damage is detected,
replace the coupling half.
8. Inspect the shaft cavity of the hydraulic pump for the presence of hydraulic oil or evidence
of hydraulic leaks. If a hydraulic leak is detected, the shaft seal must be replaced.
9. Install the new flexible coupling over the coupling half on the motor shaft, aligning the
splines, and push the flexible coupling on as far as it will go. The internal ring or snap
ring keeps the coupling centered between the motor and pump shafts.
10. Move the motor and pump assembly together to re-engage the flexible coupling with the
coupling half on the pump shaft. You may need to turn the motor shaft to align the splines
with the pump shaft. When the motor and pump are rejoined, the coupling will have a
small amount of end clearance to allow the coupling to float.
11. Attach the pump to the motor by reinstalling the bolts, and remove the wooden blocks.
12. Reinstall the vibration mounts to the frame base plate.
