And to give another comparison, my Sanden gets used probably 10-15 hours a month (of compressor run time). So I'm up around 60-75 hours of it going. This is without any sort of oiler or inlet filter (I have 2 spare compressors, not worried about it). Today it FINALLY started making some ticking and clicking noises that I'm willing to bet are valves or rings worn out.

So figuring if you go wheeling once a month and use it to air your tires up (10 minutes of compressor run time), there is no reason in the world why you shouldn't get minimum of 10 years of use out of it (using my example it works out to 45 years).

Awesome write up.

If I may thread jack a bit, do you have any interference issues with those battery terminals? I've wanted to use a set of those for awhile, but wasn't sure if the positive would touch the hood and short out.

No not until a ran a bigger battery, but i did use terminal covers to be safe. I've since relocated the battery and used a junction block to cut down on the number of cables going to the posts.

Awesome write up, just finished my conversion, this thread was a big help. One question though, is your compressor fairly audible when engaged? I ask because I can definitely hear mine when it turns on, and my oiler is probably about 4 feet back from the compressor, so I'm just wondering if the compressor is being properly lubricated.

You leave the ground wire the way it is, and bring power to the other wire.

Would you be able to tell me the exact make and where you got the pressure switch and the oiler?

you know youve got it bad when you wake up and you're first thought is "i wonder how to convert my A/C to OBA." ESPECIALLY when you hadn't been thinking about it previously!

Like everyone else has said, This is by far probably the best write up on here. I've looked at others but it seemed to be too complicated, but this has spelled out most of it. still a little fuzzy on the manifold part but im sure ill figure it out as i go. I think I've got the switch issue down. One point that was brought up, by Mickey_D i believe, was that of a thumb throttle for the compressor. How in the world would that be incorporated?

Props to everyone who contributed.

OH,, also forgot to ask

Russo, in your install pic, that black cylindrical component IIRC to the right of a white overflow tank, is that your inline oiler??

^ Thumb throttle to keep the rpm steadily raised, speeds up compressor fill rate. That way you don't have to wait so long in between tire fill ups and etc.

Thanks for posting this. Fantastic ideas. Anyone have more details on how to do this with a york or another stock compressor and keep the AC?
