Electric motor to drive compressor?

[freepowder]

Check out my writeup for some ideas that may help. I used the factory A/C one and it works fantastic. https://forum.ih8mud.com/60-series-wagons/586422-c-compressor-board-air-writeup.html

Kinda what I'm looking at but I want to mount it in the air injection pump location and keep the a/c (after many years in a FJ55 a/c is just too cool. Pun intended).

Extreme air has a Sanden already converted and set up for zerk accessable grease lubrication for $400. I'm pretty lazy and I can save up the $500 it's gonna end up costing me with widgets if the washing machines in my rentals will quit breaking down.

I also worry about junkyard compressors--have had issues with junkyard stuff in the past and as I live in the sticks not a lot of stuff available without a lot of driving--us rural folk tend to keep non-runners on the back forty for parts and so the wife has something to bitch about.

I am gonna save your thread for the rest of the setup.

I've got a 7# propane tank with the old style valve, any reason I couldn't use that for an air tank? It would tuck up underneath the gas tank where the spare used to live nicely.

That should work fine for a tank, the pressure in a propane tank is pretty low under normal use but they seem very strong and that would be a good size, if you have enough CFM then you don't need much storage, just need a little so the compressor doesn't cycle on/off rapidly.

Not really. A short tractor PTO drive shaft or even a set of U-J's from Borgeson and a slip-shaft would let you mount it roughly in-line with the PTO's outputs somewhere convenient fore or aft of the PTO unit itself.

Bigger issue would be if it can be run while driving down the road or if you can only fast idle the engine to run it while sitting still.

Can you run the PTO with the t-case in gear?

Thought about that but it would need an a/c clutch on the pulley and I don't know if I'm capable of engineering that. There would be some serious fabrication involved in mounting too.

Or, set it up so it uses a belt driven off one of the other accessory pulleys (i.e. weld/bolt a 2 row pulley to the Alt, for instance), and make a simple tensioner. Then you slip on the belt and tension it to run the pump, slip it off when you're driving.

KISS is my mantra, because I'm simple AND stupid.

No idea since I've no familiarity wit this type of PTO.


For those of us with later model V-8's Kilby makes some alternator pulleys with V-belt grooves outboard of a serpentine belt set of grooves.
