I went messeing around with a junkyard A/C pump in an attempt to gain on board compressed air. The belt that Autozone sold me was too short to fit. The gave me a Kelly Springfield 17345 which they say is 34.5 inches in circumference. Not sure if that's inside diam. or outside. Anyway it didn't fit. I tried a bunch in the parking lot till I settled on a 36 inch one. #17360 The tensioner pulley is very close to the long end of its adjustment.

The A/C pump is another junkyard gem I snagged for $30 including bracket from A-J Salvage in town. I got it to pump up a 31x11.5x15 spare tire from 0 to 40 Psi in about 40 seconds in a test today. With a tank and a pressure switch this will be a very popular item on larger trail rides where there are several pavement miles to the nearest fast air source. (CO4RJ will be the real test of the finished product.)

Leave the $300 12 volt vibrators at home.

i don't suppose you have a write up of this !!!
i think i understand the basics...just how do you get the air from the compressor to the tires and is it hard to fab up??

thanks

I'll probably make a proper write up when I get it perfected with pressure switch, tank, in cab cut off switch, air tools, etc. For now I use a switch under the hood to get 12 volt to the clutch. I didn't seal up my fittings with teflon tape yet either. It leaks a little.

I'm just experimenting with it for now. By mid summer I expect to have super loud air horns, easy tire inflation, bead seating capability, air impact wrench capability and 5 gallon tank capacity. I can't forget to mention the hand throttle I made from a bicycle shifter that acts as an idle up device.

I got tired of driving on twisty highways with 12 PSI tires to find a decent air pump at a gas station .

that sounds great! i've been wanting something to air up for awhile...i found somebody's write up of a fabbed up powertank but it ended up costing him close to 250 and powertanks are around 350.....but yours seems much more reasonable

i did this a/c compressor for a air pump a couple years ago. i used the one from a 22re celica. i just cut the metal ends off the a/c lines and clamped on the fittings you use on your compressor at home to plug the air tools in. them you just carry a long hose with you and a air chuck. you definitly have to pour oil down the hose where the air is sucked in because toyota a/c compressors don't have oil stored in them. oil is in the refrigerant thats what lubesthe bearings. mine locked up after filling up a couple sets of tires. you got to dump oil down everytime you use it to make them last cant skip any times. i know from experience i went threw a couple before figuring it out. they do work real good like a big at home air compressor. i noticed with my truck it does not even bog down the engine when using it so you should not need the cable to throtlle up.

For now I have a little piece of rag clamped on the end of the suction hose. I dump a little Campbell Housfeld oil in the rag before each tire. On the pressure hose I have an oil/water seperator so the oil dosen't end up in the tires.

It's still a work in progress.

that sound s cool that way they should last. i was amazed how good it worked when i 1st did it.i don't have the air tank since i just use it for filling up the tires. it only cost me $60 dollars total for the setup.

rabidbeaverbaby

can you have more than one a/c compressor hooked up? (one for regular a/c and one for filling up my tires) or would it be easier to just move the belt from one to the other?

this sounds so cool....i just dont wanna give up my a/c

Depends on what motor you have Mr. Beaver. For a 22RE, Budbuilt makes a bracket that will let you piggyback a York compressor (Common on Jeeps, Fords, GM stuff and other American trucks) onto your Nippon Denso stock AC.

If you have the V6 motor there isn't enough room to squeeze a York in there. You'd be better off running a 12 volt air compressor. However the good 12v ones are very pricey.

Since i didn't start with ac I had tons of room to work with. I paid $30 for a junkyard Nippon Denso compressor and a few more dollars for oil seperator, hose, belt, etc. Considering gas station air pumps are typically 25 cents per tire, it should pay for itsself in 2 years of wheeling. Its great to not have to drive to a gas station at trail pressure.

well i do have the v6 Mr. JX so i guess i'm screwed huh? oh well...there is this as an alternative (the CO2 tank) to the power tank....have you heard of this and is it as good as the powertank??
