Instruction Manual for F1300/1600 Mud Pump
23
Sludge should be drained out of the pump in setting chamber located on the frame wall underneath
the crosshead inspection doors.
Check once each month; remove clean out covers on both sides of pump to drain oil with sludge from
setting chamber. Approximately 15-gallons of oil are lost; replenish the main reservoir to compensate
for the amount drained out.
Check once each week; remove one of the lower 1/2" cap screws that secure the clean out cover to
the frame to drain off water condensate.
Check ONCE EACH TOUR, check oil level in main reservoir. Maintain at full mark on dipstick to the
manifold block. If loss of pressure occurs, check as follow:
z Clogged suction screen
z Low oil level
z Slipping V-belt drive
z Broken or loose connections
z Damaged or worn oil pump
z Defective Relief valve
For an abnormal increase in oil pressure, check for:
z Plugged oil lines
z Sludge causing oil to be viscous
z Relief valve inoperative
z Defective pressure gauge
z Other conditions
3. Maintenance
3.1 Power End
Routine inspection of the power end is the most important form of preventive maintenance and will
result in considerable savings by detecting any major trouble that might be developing and allowing
the necessary repairs to be made on a planned or transport rig-down time.
3.1.1 Check tightness of the main bearing bolts.
Bolts must be tightened as the following torque: 13210 N.m (9750ft.lbs)
3.1.2 Lock wires
Check lock wires on all bolts including the main bearing hold-down bolts and eccentric bearing
retainer bolts. Replace any broken wires after retightening the bolts. Refer to crankshaft assembly
section for bolt requirements.
3.1.3 Oil lines
Check all oil lines to insure they are intact and free of obstructions. Check oil pump suction hose for
damage or flat areas.
3.1.4 Suction filter
Check condition of suction filter. Clean and replace as required.
