I didn't think this was a pressure lubed machine. Is it leaking around the shaft seal, behind the flywheel? If it's just the oil leak, and the unit runs/sounds fine otherwise, you could put a gasket and seal kit in it.

You can search online for parts, but probably have better luck calling it a LeRoi 660A. Compair bought them years ago, and let the piston compressor business slowly die.

How do you replace a oil pump on a 2000 avalon


It's my understanding that the Avalon and Camry for said year are the same in respect to
the oil pump.I was able to come up with a video to show you how all the stuff has to be removed
from the front of the engine in order to get to the oil pump for replacement.This took some time
to find,but I do not mind.My friend,you've a lot of work ahead of you.I've been thru it before,and
won't do it again.Best of luck to you in your endeaver.

Now the oil pump proceedure in print:
Instructions
Remove Oil Pump
1
Drive your Toyota Camry up onto ramps or lifts so you have room to work as you pull out the oil pump.
You could also use a jack, but make sure you brace the front wheels so they don't roll. In addition,
set the emergency break firmly into position so the car doesn't roll.
2
Drain the oil out of your engine and disconnect the negative battery cable. Remove the fender apron
seal and the undercover, the front exhaust pipe, and the front exhaust pipe bracket from the No. 1
oil pan.
3
Remove the following components in order: the alternator drive belt, the air conditioner compressor,
the power steering pump drive belt and the adjusting strut, the timing belt along with the belt
pulleys, the rear timing belt cover, the air conditioning compressor housing bracket, the No. 2 oil
pan and oil strainer, as well as the No. 1 oil pan and baffle plate.
4
Disconnect the crankshaft position sensor and remove all nine of the oil pump bolts. Remember where
each bolt was located.
5
Take out the oil pump body by reaching in and grasping between the oil pump and main bearing cap.
Remove the O-ring from the cylinder block then remove the plug, gasket, spring and relief valve
from the oil pump body.
6
Finish by taking out all nine screws, the pump body cover and the driven rotors. Clean all
components to remove contaminants.
Install the Oil Pump
7
Install the new oil pump by slipping it into the same spot where the old one was. Reconnect
the following: the driven rotors, the drive pump body cover, all nine screws, the oil pump
relief valve, the spring, the gasket and the plug to the oil pump body.
8
Insert a new O-ring onto the cylinder block and add liquid sealant to the oil pump and the
engine block. Put the oil pump back on the engine block.
9
Add and tighten the bolts over several passes, keeping the torque even. The 10 mm head should
be 69 in-lb. and the 12 mm head should be 14 ft-lb.
10
Reconnect the crankshaft position sensor, torquing the bolt to 69 in-lb. Insert the No. 1 oil
pan and oil strainer and the No. 2 oil pan.
11
Reinstall the air conditioner compressor housing bracket, tightening the bolts to 18 ft-lb.
Add the rear timing belt cover, tightening those bolts to 74 in-lb. Insert the timing belt
pulleys, the timing belt and the adjusting strut and power steering drive belt, tightening those
bolts and the nut to 32 ft-lb.
12
Install the air conditioning compressor, the alternator drive belt and the front exhaust pipe
bracket to the No. 1 oil pan, torquing the bolts to 15 ft-lb. Add the front exhaust pipe, the
undercover, and the right fender apron seal.
13
Connect the negative battery cable and fill the engine with fresh oil. Start your Toyota Camry
and look for leaks in your working area.

The air hose has oil leaking


Usually, oil in the discharge air indicates too much oil in the pump or oil too thin (in hot climate use oil treatment). If oil level is known to be correct and oil not to thin, indicates worn cyl /rings. Easy to check. Remove bolts holding cylinder to body/base of pump. Pull off cylinder with head attached to examine piston and rings. Replace parts as needed.

Will not build pressure


If your compressor is oil-less type, most likely pressure is leaking past piston ring. To verify, remove cover to expose bottom of cylinder (unplug compressor and let out all air). With flashlight, examine the upper-most part of the cylinder (turn motor by hand till piston is at top of stroke). If top of cylinder is scratched, then pressure is leaking past. If cylinder looks good, most likely problem with reedvalves or broken gasket in pump head. Parts are not too expensive for most small compressors. If your compressor is oil lube type, problem sure to be in the head assuming no leaks. Good luck

Air compressor runs but i only get 20 psi i check for oil but i never find were to test the oil level do this air compressor is oilless?


Yes it has no oil. and you need to remove the top cover and check for air leak between the pump an the tank. if you have a large leak the tank will not fill. Two screws and the cover should snap off. check copper line for blown seals.

Oil free pumps do tend to blow the piston ring (not too expensive) available at searsparts.com. Remove covers to pump and manually turn crank until piston is at top and look at the condition of the cylinder neer top, If it looks scratched, order cylinder kit with piston ring. If it looks good and shiney, could be the valve plate in the head. There are reed valves that tend to break. Run pump however with covers removed and check with soapy water for air leaks and repair as needed (air leaks under the cover will prevent unit from filling). Good luck

How to change Oil Pump


3.3L Engine

The lubrication system is a full flow filtration system pressure feed type. Oil from the oil pan is pumped by an internal gear type oil pump directly coupled to the crankshaft. Its pressure is regulated by a relief valve located in the timing chain case cover. The oil is pumped through an oil filter and feeds a main oil gallery. This oil gallery feeds oil under pressure to the main and rod bearings and the camshaft bearings. Passages in the cylinder block feed oil to the hydraulic lifters and rocker shaft brackets which feeds the rocker arm pivots.
It is necessary to remove the oil pan, oil pump pick-up tube and timing Chain Case Cover (CCC) to service the oil pump rotors. The oil pump pressure relief valve can be serviced by removing the oil pan and oil pickup tube.
  1. Disconnect negative battery cable and drain the cooling system.
  2. Remove the radiator assembly.
  3. Raise and safely support the vehicle.
  4. Drain the engine oil. Remove the oil filter.
  5. Disconnect the sway bar and place it to the rear of the vehicle to gain access to the oil pan.
  6. Remove the transmission support brackets and inspection cover.
  7. Remove the oil pan and the oil pump pick-up tube.
  8. Lower the vehicle.
  9. Remove the accessory drive belts and tensioner pulley bracket.
  10. Remove the power steering pump and set aside. Remove the air compressor mounting bolts and set compressor aside. Remove the compressor mounting bracket. It is not necessary to disconnect the refrigerant lines or evacuate the refrigerant from the air conditioning system.
  11. Using an appropriate puller, remove the crankshaft pulley.
  12. Remove the tensioner pulley bracket.
  13. Remove the camshaft sensor from the chain case cover.
  14. Remove the timing chain case cover mounting bolts and the cover from the front of the engine.
  15. Clean the gasket material from the mating surfaces of the cover and the block.
  16. Remove the oil pump cover retaining screws from the timing cover. Lift off the oil pump cover.
  17. Remove the pump rotors. Wash all parts in solvent and inspect carefully for damage or wear.

To install:
  1. Clean all parts well. Assemble the oil pump with new parts as required. Install the inner rotor with chamfer facing the cast iron oil pump cover.
  2. Install the pump cover and tighten the fasteners to 9 ft. lbs. (12 Nm).
  3. Prime the oil pump prior to installation by filling the rotor cavity with clean engine oil.
  4. Remove the crankshaft oil seal from the front cover.
  5. Install a new cover gasket and O-ring onto the cover.
  6. Rotate the crankshaft so the oil pump drive flats are vertical. Position the oil pump inner rotor so the mating flats are in the same position as the crankshaft drive flats.
  7. Install the front cover making sure the pump is correctly engaged on the crankshaft, or severe damage may result.
  8. Install the chain case cover screws and snug the two bottom screws and the top center screw. Ensure the cover is seated to the block then tighten all screws to 20 ft. lbs. (27 Nm).
  9. Install the oil seal and the crankshaft damper.
  10. Install the tensioner pulley bracket and the cam sensor.
  11. Install the air conditioning compressor to the mounting bracket.
  12. Install the accessory drive belt.
  13. Raise and safely support the vehicle. Tighten the oil pan drain plug and install a new oil filter.
  14. Install the oil pump pick-up tube and oil pan. Install the transaxle inspection cover, if removed.
  15. Fill the crankcase with clean engine oil to the proper level. Install a new oil filter.
  16. Install radiator assembly. Check condition of radiator hoses. Fill and bleed the cooling system.
  17. Reconnect the negative battery cable. Run engine and check for leaks. Verify correct oil pressure with a gauge.
