Hi all,
Has anyone converted there A/C pump into a air compressor for pumping up tyres?
If so what did you have to do to converted it?
Is it a good idea?

Lots of good info on the web re this. To do properly costs a bit over 100 but you get a pump that will inflate a flat 33 in about 2 minuites. You loose you air con though.
Get the unit degassed correctly. Dont just release to atmosphere.

They work very well.
As geeves said, get it degassed to save the atmosphere, then change the fittings on the pipes to suit. It pays to put a foam filter on the intake end so no dust or that can get in. I have seen 2 set-ups for the discharge side, one was a pressure release/dump valve (a safety valve off a air compressor would do the same trick) or with a pressure switch (also off a air compressor.
If you go the release valve way then it means you cannot over pressure anything, but you need to start your pump every time you want air.
If you go the pressure switch way then i would also recomment putting a tank in as well, even just 2 to 4 litres, it means that you also cannot over pressure anything as you set the cut-out pressure, and you always have a bit of air on hand if your running air lockers or air horns!!!!. Its easy to wire up, and you can still use your existing air con button. i did this on my mates truck and it works a treat.
just remember to give the pump a few drops of oil every now and then so it doesn't sezie on you!!!!

From memory, search Offroad Express to be sure, a Volvo car AC compressor has permanently lubed bearings so you don't have to oil then de-oil them.

An interesting way to lube the compressor that Ive heard was to take the air intake off of the crankcase breather. This will take its air from the intake side but there is always a little oil around so no worrys about the lube.
A lot of the european cars have piston type compressors that dont need lube Ours are rotary so will fail without lube after a few years or so.

I have seen an air con compressor mounted low on the left side of the engine for use as a pump. He did this so he could mount his alternator on tthe normal air con bracket rather than an extra pump but should be possible. He was an engineer so was able to make all the brackets

another way to keep it oiled is an in-line air tool oiler, you just have to buy an adator nipple.

Great mind's think alike, i'm not sure if you can get one, but a 1/2 inch bsp one would be big enough. I thnk a 1/4 inch would restrict the flow too much.
