Lubrication for Wheatley GASO Piston Pumps - Power End
Gears, connecting rod bearings and crossheads in all geared piston type pumps are lubricated by splash from lubricant in the crankcase. Crankshaft bearings and pinion shaft bearings in Series 1800, 1500, 1600. 1700. 1900, and 2600 pumps are also lubricated from this same crankcase oil by splash.
Shaft bearings in Series 1550-C. 1654-C. 2000 and 2200 pumps and in pumps with serial numbers 24523 and below are sealed off from the crankcase lubricant by oil seals and run in a separate bath of oil retained in the respective bearing housing.
Warning
The crankcase is drained after factory testing. Remove the crankcase cover or crosshead guide hand hole cover and fill with sufficient lubricant before starting the pump for the first time.
Crankcase Oil for Wheatley GASO Piston Pumps
Quantity and type of lubricant required to fill crankcase to the proper level is shown below.
For herringbone gear driven pumps operating in average climates, use SAE 90EP, AGMA 5EP, OR AGMA 6EP gear lubricants. Be sure. however. to use an EP lubricant that will not have a corrosive action on bronze and that contains rust, oxidation, and foam inhibitors. Multi-purpose multi-viscosity gear lubricants are UNSATISFACTORY for use in Gaso pumps. For chain and sprocket driven pumps use a SAE 30 high grade mineral oil or AGMA 3EP in the crankcase.
For worm driven pumps, use a SAE 140EP gear lubricant. We can help with your oil and lubricant >>
Running temperature of crankcase oil should not exceed 180° F. If higher temperatures occur and mechanical fits are found to be correct the use of a separate oil cooler is recommended. For low ambient temperatures, select an oil with a pour point lower than the lowest anticipated ambient temperature. Consult Wheatley Gaso factory for recommendations when unusual operating conditions exist.

As soon as the correct lubricant has been added, replace the crankcase cover and install breather(s) on top to provide for positive ventilation.
Lubrication of Shaft bearings in Series 1550-C, 1654-C, 2000, and 2200 - and for pump serial numbers 24523 and below:
These pumps are equipped with inner oil seals on the pinion shaft and crankshaft. Therefore, they run in a separate bath of SAE EP 90 Gear Lubricant. AGMA EP 5 Gear Lubricant, or SAE 50 high grade motor oil or mineral oil. The bearing housings are properly filled before leaving the factory: however. a check should be made to see that none has leaked out or been removed. Proper oil level is even with pipe plug in the lower part of the bearing housing flange or cover plate.
Inspection should be made regularly to determine if any loss has occurred by leakage past the oil seals. If necessary, add oil through a plugged hole in the top of the bearing housing flange. Do not fill above “oil level” as too much oil will churn and create excessive heat. Remove cover plates, flush with kerosene, inspect bearings. and refill with clean oil at least once every six months.
Normal running temperature is 140° to 160° F with a maximum of 180° F.
Pumps with herringbone gears. Serial No. above 24523 do not have inner oil seals installed for the pinion and crankshaft bearings as standard equipment; however, your pump may have these seals installed as special equipment. If your pump has inner oil seals installed, the amount of oil required for the crankcase is as follows:
| Pump Series | 1800 | 2200 | 1500 | 2000 | 1600 | 1700 | 1900 | 2600 |
| U.S. Gallons | 2-1/2 | 5 | 6 | 10 | 8 | 10 | 15 | 18 |
Daily inspection of oil in crankcase for Wheatley Gaso Piston Pumps
Check oil level and appearance daily. Change oil and clean the breather every six months or 2000 hours run time. more often under severe operating conditions. The crankcase should be thoroughly cleaned at each oil change. Contamination of oil by saltwater will be indicated by the oil turning white, milky, or foamy. Contamination of the oil by moisture condensation will be indicated by the oil slowly turning dark or a rusty brown. Whenever any type of contamination or dilution is detected, drain the crankcase. remove the crankcase cover and crosshead guide handhole cover, thoroughly flush out the oil and refill with clean oil to the dipstick full mark. Do not overfill. At the same time. check and clean the breather. Oil lost by leakage should be replaced before the level becomes too low. If leakage is excessive, check the packing in the crankcase stuffing boxes, the oil seals on the pinion shaft. and clean the crankcase breather. Replace any shaft seals that are damaged or worn. Some pumps have replaceable wear sleeves on the pinion shaft that should be replaced if grooved.
