Maintenance and Repair

Booster Pumps

7. Disconnect airlines, electrical switches, and

the tachometer cable as required.

8. Attach a proper lifting device before

loosening or removing mounting brackets.

9. Disconnect mounting brackets to remove

the pump and gearbox assembly.

10. Place the pump and gearbox assembly on a

stable work stand. The air vent and gearbox
cover are exposed. This will provide easy
and safe access to the internal components.

REINSTALL PUMP ON APPARATUS

After completing repairs and /or maintenance,
reinstall the pump and gearbox assembly.

1. Place the pump and gearbox assembly on a

stable platform. Attach a proper lifting
device.

2. Lift the pump and gearbox assembly into

position on the equipment. Connect the

mounting brackets using the proper
fasteners. Torque the fasteners to values
provided in Table 5-3.

3. Connect the drive shaft to the gearbox.

Apply Loctite™ to the fasteners and torque
to PTO manufacturer's specifications.

4. Connect any electrical switches, airlines and

tachometer cable if appropriate.

5. Install the magnetic oil-drain plug.

6. Fill the gearbox to the level of the oil plug.

Use only oil with an API GL-5 rating. Use
SAE EP-90, 80W-90 or synthetic 75W-80
oil. See Table 5-1 for approximate gearbox
oil capacity.

7. Reconnect the suction and discharge piping

to the pump.

8. Test the pump for proper operation, note any

leaks.

9. Return the apparatus to normal operation.
