Howdy from Oklahoma

[Ryvexuz]

Bought a m939a1 after a breakup a few months back that I had wanted to turn into an expedition vehicle… but have more recently just started toying with it, In my free time at work between teaching stuff and actually working, I work on it in the parking lot. This week it received a turbine pneumatic starter. Getting ready to mount brackets up for the air tank. Not 100% sure what this vehicle is going to turn into at this point. But, at the rate it’s going who knows. Took the bed off, removed the intake and exhaust and was planning to reroute the exhaust. Right now it’s straight piped and that’s… a fun adventure for the ears. Redid the fuel system, changed out the alternator, removed the batteries and most of the interior. List goes on, anyway… howdy picture of the starter system outside the truck.

Welcome to SS! I am about 70 miles west of you!

Welcome to the site! Quick question about your air starter.... these trucks do not retain air worth a flip... how do you intend on having enough air pressure to roll your starter over after a few days of sitting?

Not being snarky, genuine question.

Right now just using that 20 gallon air tank in the picture. In the process of mounting it where the air filter used to be under the cab. It has a check valve on it that I’ll have connected to the air brakes. So when they fill it’ll fill back up but since it’s more independent of them when they leak out it’ll retain pressure. If they still have pressure and for some reason it needs additional starts they can still bleed into the tank to help with additional starts. Just had it running without any of the batteries or electrical components attached and having used the fuel bypass screw. There’s also some extra fittings on the tank for if it needs extra starts and needs to be filled back up when the truck isn’t running or won’t. Photo has the tanks and the air lines temporarily placement while it gets sorted

Hello and welcome to the group. What was your reasoning for converting to pneumatic over electric start?

Welcome to Bedlam. There is no turning back.

there was no practical application, it was predominantly just a student said it would be cool. And I thought yeah, why not? The starter had gone out already and it was just a few hundred extra steps to make it air…

Welcome from Northern Ohio! That starter will sound pretty cool, just like the mad max road warrior truck.

I have seen a couple old Detroit 16 cylinders that used air starters. They are unique and pretty cool.

Those Detroit are actually what that guy had been talking about originally. He was trying to convince me to put the ol 2 stroke Detroit into it.
