You have the V-MUX system. It is manufactured by Weldon Brass Company. Re-programming it gets expensive, but if you leave it as-is, it will probably panic if your (non-existant) oxygen bottle pressure is low. Parts for it are available, but a new display runs about $900. Components are available on eBay, and sometimes as ambulance dealer surplus - check www.fostercoach.com for ambulance parts.

I have some operating instructions I'll post later today.

Do the axles have any failures, or will you be tearing them down just to overhaul them? You might wish you had a military wrecker before you're done - maybe a nice old Diamond T 969 twin boom wrecker?502579

No failures but I am changing the centers from 6.8 overall to 5.6 overall ratio to allow for the “little” 43” tires. I also figure new seals would be a good investment when they are this far apart and at a good working height.

Time to chop the spring perch’s off.



This is going to be a PITA without an oxy kit, gouging rods or a plasma.

Nicely done. Probably a little slower than an air-arc, but definitely neater. There's always a trade off between time and technique.

I learnt to drive real trucks in a Diamond T with a 10 speed box (no synchromesh back then) 4 speed jockey box and 2 speed diffs. Geared to do 45 mph top speed. Pulling an early cable blade D9 on a low loader.

That’s why I love the Allison transmissions.

Dang me, thats a big girl. And axles, wheels and tires are going to add a fair bit too!
