351 AC compressor as an air compressor?

[4x4xTOR]

As stated in an earlier post, I am installing a 351 EFI in my bronco. The engine is from a 2 wheel drive 1990 F-250. My next question is.... Can I convert the ac compressor to an on-board air compressor? If not, what can I do if I remove the compressor ? Is there some kind of air conditioning delete type pulley I can install to retain the original belt length? What are my options? Thanks TOR

I used a 5.8 (351W) from a 93 Bronco and used the AC pump for on-board air. Here's a good link on how to do OBA with a Sanden style pump and have it live http://nwjeepn.com/onboardair.htm . There are a few pictures of mine in my gallery.

You can also buy an AC delete pulley from Summit http://store.summitracing.com/partd...&N=700+4294851751+4294908331+115&autoview=sku .

Coblu77, I am thanking you before I check the links you supplied. I will check back in with what i come up with.TOR

CoBlu comes through! Dude, the link from summit is exactly what I am looking for. The other option looked way too expensive and time consuming for me.Thanks again.TOR

TOR, there's no reason to spend a bunch of $$ on making that AC compressor work great for OBA. I've done it a bunch of times.

The cheapest/easiest way to do it is to go to the local auto parts store and buy one of the $50 air compressors they have on sale. Then rob the air switch, tank, etc... and convert them for use with the AC compressor.

If you need some more info shoot me a PM.

I have very little money in mine and run 150psi. got most of the parts from Lowes and Ebay.

I just converted mine over the weekend.
Cost was about $75
Pressure switch $40
Blow off $ 10
Brass Tee $3
Nipples & miss fittings $5
Oil/water separator $10
inlet filter - borrowed from my other Bronco.


I do not use a tank just straight off the compressor, gets the job done.

these inexpensive ideas have got my attention. I will get back to you guys once we have the 5.8 in the truck and it is running. See you soon.TOR

If your just using it to air up tires go real cheap and just skip the pressure switch put a simple on off toggle to start it up. Just make sure you have a good blow off valve or possible 2 just for back up. My two gallon tank takes about 15 secs to fill up to 115 lbs where the blow valve blows. Its a bit annoying listening to it blow when your moving around from tire to tire, but it fills the tires just fine and plenty fast. I air up from 10-12lbs to 30lbs in about 5-7 minutes all four tires. Plus its great for scarring the heck out of unsuspecting people standing next to your rig.
