Many small air compressors are made with ceramic internal parts, when they wear out there is no fixing them, one must buy another compressor

SOURCE: Electric Air compressor

Is it building pressure in the tank and just not going out your air hose ? Or is it not building any pressure in the tank?If it is building pressure than the problem is narrowed down to your outgoing channels which does simplify things.(-8 Either something has got clogged in the outgoing airway, or there is a good possibility that the pressure regulator needs new parts if you can find them or just replace it. Have you tried turning the regulator output up or down? It may be stuck all the way closed which would shut off the air coming out.If your not building any pressure then the piston/s may need new rings or the cylinders are scored and need machine work. That part works basically the same as the piston/s and valves in an automotive motor. Except instead of pulling a fuel mixture in and igniting it for power and then pushing out the exhaust, it pulls in air and pushes it into the holding tank compressing it to X# of psi with the assistance of a check valve.

SOURCE: Makita MAC2200 runs fine (with new Manifold Switch

I have worked on many makita compressors and have run-across this problem on a few of them. Your compressor has a check valve that is supposed to hold tank pressure after the switch reaches set pressure. There is an unloader valve built into the pressure switch that releases the pressure in the discharge hose after the unit shuts off. The unloader allows the compressor to restart with-out any pressure in the discharge line. If the brass check valve is leaking pressure back into the system, air will leak out of the unloader valve. Follow the discharge line to the tank and you will see the brass check valve. To test valve for fault, run the compressor till it builds around 80 psi and unplug the unit from the wall outlet. Remove the 1/4" hose connector from the check valve and check for air leaking out of the valve. If it is leaking you can order form www.toolpartsdirect.com. or call the makita 1-800 number. The price is about the same. Good Luck on your repair.

SOURCE: Craftsman air compressor 1 HP 12 gal 125 psi

this is probably an "oilless" compressor, it has "piston" with a thin ring of leatherlike material acting as a piston ring, the "cylinder" is an aluminum sleeve - what usually happens is the cylinder gets scratched from dirt or just wear or the leather ring deteriorates, that's why it will go only so far - the only fix for this is to replace the cylinder and the piston

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

12 gal 2hp instruction manual


You didn't give your model number so here's a possibility: If it's vibrating that much it's usually a good indicator the air pump connecting rod is broke. If it's been in storage it's possible the oil evaporated enough or it didn't have enough in it that it didn't lubricate the con-rod bearings. It would have started the first time but as heat built up in the bearing areas it could have seized up when it was shut off or broke when it tried to restart. You'll have to take the air pump apart to verify what's broke and what's damaged and what has to be replaced. Most Craftsman parts are only available through Sears (www.searspartsdirect.com).

Trying to replace the water pump on my Saturn SL2 1993. I removed the 3 bolts of the pulley, but there is no room to get teh pulley out (its right up against the engine compartment wall. How do I remove...


Check and note this procedure Water Pump - REMOVAL & INSTALLATION
(see Figures 1, 2, 3, 4 and 5)
  1. Allow a sufficient amount of time for the engine to cool down.
  2. Disconnect the negative battery cable. Drain the engine coolant from the radiator and block drains into a suitable clean container.
CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant may be reused unless it is contaminated or several years old.
  1. Remove the serpentine drive belt.
  2. Raise the front of the vehicle and support safely using suitable jackstands. Remove the right front tire and inner wheel well splash shield.
  3. If access to the water pump is desired from underhood, remove the air conditioning compressor bolts and position the compressor aside with the refrigerant lines intact.
  4. Spray the water pump hub with penetrating oil to loosen any rust or corrosion that might bind the pulley and damage it during removal.
  5. Remove the water pump pulley bolts and allow the pulley to hang freely on the hub. A 1 in. (25.4mm) block of wood or a hammer handle may be wedged between the pump and crankshaft pulleys to hold the assembly while loosening the retaining bolts.
  6. Move the pulley outward or remove as necessary for access and remove the 6 water pump flange bolts. Carefully pull the pump and pulley assembly away from the engine and remove the assembly from the vehicle. If necessary, a gasket scraper may be inserted under the flange, but be careful not to damage the machined aluminum block sealing surface.
To install:
  1. Thoroughly clean the gasket mating surfaces of all old gasket material. Apply a small amount of gasket sealant at the outer edges of the bolt holes to hold the gasket in place, then install the gasket onto the water pump assembly.
  2. Install the pump assembly with the small bump located next to one of the attaching bolts in the 11 o'clock position. Install and tighten the bolts in a crisscross sequence as shown to 22 ft. lbs. (30 Nm).
  3. Install or reposition the pump pulley, as applicable and tighten the bolts to 19 ft. lbs. (25 Nm). If the pump hub exposed through the pulley is rusty, clean it with a wire brush and apply a thin coat of primer to prevent the pulley from rusting onto the hub.
  4. Install the serpentine drive belt, the right splash shield and right tire assembly.
  5. If repositioned, install the air conditioning compressor.
  6. Close the radiator drain plug and install the cylinder block drain plug. Tighten the block plug to 26 ft. lbs. (35 Nm).
  7. Connect the negative battery cable and properly fill the engine cooling system.
  8. Operate the engine and check for coolant leaks

Mt tire in the front poped and I can not inflate it?


Do you have a tube it the tire? if you don't, pull the wheel off and lay in flat on the ground, put pressure around the tire at the rim edge and begin to pump with a compressor. A regular hand pump is hardly sufficient. You may even try standing on the tire edge while pumping if you can't get enough of pressure with the hands. The point is to push the tire inward to prevent air bypassing while pumping.

Portable Air Compressor Comparison


Portable air compressors give flexibility to the job both inside and outside the working environment. They're powered by electric, gasoline or diesel engine. A larger portable air compressor often has its own carrying trailer with wheels and handles. You buy a compressor based on its horsepower, pounds per square inch (PSI) and cubic feet per minute (CFM). Choose a portable air compressor to make work quicker and easier. Figure the amount of power you need based on the type of job and air tools used. Know the cubic feet per minute (CFM), such as 5 CFM for small household tools and 10 CFM or more for wrenches or sanders. All air tools have these ratings. Select a gas- or electric-powered engine. Gas gives a higher reliability for frequent use and portability, but consider electric for enclosed areas for its lack of fumes. Pick an air tank based on amount of use time and tools. Large tanks are best for longer use with sanders or grinders and smaller tanks for less time, like wrenches and air hammers. Consider the pump type you need: belt for heavy use or direct-drive for light home use. The quieter belt-drive pump needs periodic oil changes. Buy an inexpensive, small electric portable air compressor for small jobs. These typically operate from a 12-volt power outlet and inflate a 14-inch tire in a few minutes. Get a 150 PSI, 120 volt motor pancake-type air compressor for home use. These light-use models typically carry two air couplers, allowing hook up of two air tools and adequate 25 feet or more air hose. Obtain a larger PSI portable air compressor for bigger jobs, like nailing, with longer continuous use capabilities.
