Thread: Engine mounted, belt driven air compressors? Has it been done?

Go to a truck wrecker and look around the engine bays. You will find something that may already be belt driven or able to have belt pulley fitted.

Dave, did you ever do anything with that Bendix Tu-Flo 12 cfm compressor I gave you?

I use a Sanden SD7 air con compressor, grease lubricated crank case with the gallery to the head blocked to prevent grease leaking into the air ways.

It's not finished yet but I can fill a 33x12.5R15 tyre from empty to 35psi in 2 minutes 10 seconds, rattle gun 5 wheel studs off without recharge and run the drill without load endlessly. The 9L tank fills from 0 to 120PSI is around 30 seconds or so.

I will upload a test video I made of it and post it here.

I will have it plumbed into a 9L tank fitted under the drivers well.

On top of having oodles and oodles of pressure at around 9-10CFM, the torque of engine means that the compressor does not lose this capacity when the pressure increases as it will with 12v units. It provides a constant pressure which is great.

Got it all prepped up to go on the 2.25, then got the offer of the Suzi and matching lt95. Since then, she who is now divorced kept the brakes on the money for work on fozzy so he sits forlorn and in pieces.

Had I known, I'd have kept the 2.25 in him and built around that...

Exactly the compressor I have on my 300TDI defender - mounted on a home made bracket next to a 2nd altenator in the standard A/C position.
I changed the oil fill hole for a grase nipple and put a grubscrew in the gallery hole to the head. Even without a tank, it will still push tubeless tyre beads back on if you give the engine a few revs.
