ISRI AIR LEAK IN TUCSON AIR FORCE BASE
Can anybody help me? Drove to Davis Monthan AFB yesterday and 30 miles out, my ISRI drivers seat suddenly sprung a loud air leak. I drove it on the base, I’m in the FAM Camp and I don’t know who to call or get from anyone. I’d be happy if I knew what the Sam Hill to do but don’t. I can’t see much because the black rubber accordion is covering the area of concern. My son is deploying to Korea in two weeks and we thought this would be an enjoyable trip, but stuff happens. Any one that can help I would be truly grateful and even can pay for service. Thanks Michael Faul 623-258-6484.

Michael,
Go to the articles section of this site and read
Prevost Air System Leak Detection and Improvements Jon W. Wehrenberg It will give you a idea of where to start, which will be in the front compartment on the drivers side in front of the left front tire.
Look for the components that Jon talks about in the article to try and find and repair or isolate the line that is leaking.
It will give you a good starting point and some great knowledge for the future.
Good luck

For a quick fix, try this. The air seat is most likely feed air from a 1/4″ air line in the compartment directly under the driver seat. If you open that compartment and look up towards where the bottom of the seat is, you should see an air line going thru the floor. Now that you know which air line feeds the seat, put a valve in the line to shut off the air to the seat. Lowe’s and Home depot carry small air valves or a local NAPA may be able to help you.
A better way, would be to locate the leak and determine what part has failed. But closing off the air line will take care of the issue so you can spend time with your son.
Thank your son for me for his service. I am retired AF and spent some time in Korea.

Thank you John. I’ll do that.

Andre and Ann, thank you. I’ll find the hose hopefully and repair. Thank you for your service as well and God be with my son to Osan AFB. Happy Easter everyone!

Michael,
You can also remove the line and plug the fitting on the regulator, like Andre said, in the steering compartment. Suggest you put XL or H in your signature to help indentify your type conversion.

Once you identify the air line, you should be able to pick up a small Vise-Grips at a local hardware store and be able to close off the offending line. Using the Vice-Grips will enable you to confirm that the line you identify is in fact the line that is leaking. Good luck! Keep us posted. We’re all sitting here waiting to help you.

I sure wish I could help but I’m out waxing my slide seals. :o)

The ITSI seat has a lever, I believe it is the first one on the side that will cut the air off to the seat. It the leak is after that switch that will stop the leak.

On my Isri seat the bottom cushion is removable. My seat, however, is a std Isri seat not “customised” by a converter. Once the cushion is removed, there is easy access to all guts.
-
Thanks Joel I’ll check that. I’m sure my seat is not customized either. How does the seat cushion come off? -
Under the cushion in the front there is a tab you pull, then the cushion slides forward and then up and off. It’s above the bar that you would use to slide the seat forward.I just hqd had a leak too. A line was clearly rubbing the metal frame and it leaked. I used some plastic repair stuff and it worked. Lucky me.

On my vintage ISRI there are 4 plastic tabs, 2 front and 2 rear. You move the seat slightly to the rear and the seat lifts up and off. The seat has holes and the plastic tabs on the frame drop into the holes then slide into a channel that holds the seat fast.
