4. Turn off all valves on the hydraulic tank.
5. Disconnect the hydraulic hoses on the pumps that
are to be removed.
6. Disconnect wires at the electronic displacement
control if removing drive pump.
Pumps are very heavy. ALWAYS use a
hoist to lift pumps.
7. Attach a hoist to the pump being removed.
8. Remove the bolts holding the main pump to the
engine and slide out the faulty pump.
9. Check the drive coupling for wear or damage.
10. Remove all bolts and pull out the coupling from the
ywheel.
11. Clean the ywheel and threaded bolt holes with
ether.
12. Install the new drive coupling into the ywheel.
13. Cover bolts with thread-locking adhesive and
torque. (See Section 2, Torque Tables)
14. Grease the coupling and pump splines.
Load Sense/Charge Pumps
1. Check O-rings and insert the charge pump into the
main pumps.
2. Torque bolts. (See Section 2, Torque Tables)
3. Connect all wires.
4. Be sure hoses and ttings are clean, then
reconnect.
5. Turn on valves.
6. Fill the oil tank through the charge lter ll port. This
