Thanks. I'll take the wheels off and staring pulling things apart.

Not yet. Where is the CTIS seal?

I'm getting gear oil from a part mounted on the left rear frame. The part seems to be a CTIS "T" that must supply air to the rear tires/rear axle. Is there a check valve somewhere? Anyone come across this?

Has anyone found a source to replace the 2 piece style A3 wheel/rims with a one piece design? I have removed my CTIS, replaced the wheel/rim o-rings and valve stems but still lose air.

Thanks for the info, I'll contact CAT tomorrow. Do they commonly go bad?

I am looking for a A3 fan hub switch. It's the switching device that turns the cooling fan on when the engine reaches 200 degrees. It screws into the thermostat housing and has 2 air lines attached to it. I looked in the tech manuals for a NSN with no luck. thanks

We replace the factory 10 leaf rear springs with 12's. It makes a world of difference. Be sure you replace the auto trans fluid with Dexron 6.

You will have to buy a new speedo assembly unless you get creative and fabricate one

Good choice on the A3. Shoot me a PM if you have any questions on the A3's, we build them for the fire service.

FYI I knew this was coming- I had a allison 1545 auto trans out of a A3 go bad. Fluid smelled burnt and was dark. I took it to the transmission guy and he said the front pump was toast, he eventually found a new front pump for $700. He said parts for the 1545's are going to be hard to find...

I am pretty sure those are vents he thinks are leaking. On the A3's hoses run from those fittings up to the engine compartment - for forging?

I haven't seen that, but it looks like somebody must have installed it with a rock.

The TireBoss system is a great idea but those air lines sticking out will get torn off! It's amazing what a little, or lack of, air pressure can do. I think the wheel seal/o-ring design of the A3 is a huge improvement though. I don't see a way gear oil could ever contaminate the brake shoes...

After you solve your shutoff solenoid problem - You should have a dribble to a small squirt(depending on how loose the nut is) coming from the loosened injector lines at the injector.
