Start here...

18-speed Quadruplex. Double over. Adds the lo-lo range. Still has all the Bulldog Cool of having 2 sticks. Real Macks need 2 sticks. Not necessarily if you're gonna work them, but definitely if you play with them! Loved the RoadRanger that came in mine, although it was direct (no over). But, hated not having both sticks... Okay, so I have a little masochist in me!

Not sure if this helps anything, but the range shift on the 15-speed Fuller I had did not want to shift when I first started the truck. I had to sit there in neutral and flip the hi-lo several times to get it to shift. Once it shifted, it was good for the rest of the day, even if it was cut off and restarted. This was a lot more noticeable when it was cold, and nowhere near as pronounced when it was hot. I believe I had a slave valve gummed up, preventing proper air flow to the shift cylinder. That truck had a little oil in the air system, and I believe that oil was causing the slave valve to be stubborn. These air-shifted puppies can be picky about clean/dry air.

Ah! Got ya.

Maybe 24" circumference (8" diameter)??? Is that a single-chamber or a split tank?

One gorgeous R........

Dang, that's cool. I love the old steel dash trucks. And, that one's a little better than mine was! LOL!

Sounds like the hi-lo synchro is disengaging... Could be the synchro ring or the gear it engages on the mainshaft.

Wow! That's funny, Hippy! Welcome, Matt!

I'm just repeating what the instructions, which truck shop posted, said. On my Spicer, you had to remove the lock plate, too. Whatever...

Ouch!

That's pretty cool, Bob!

You may be correct.

More??????

Probably did not happen in every state. Where I grew up, it was a normal thing.

Yep. Remember it well. Thomas Built Buses had facilities in High Point, NC. Blue Bird had facilities somewhere in GA. So, we saw a lot of chassis and new finished buses in this area.

Yip. They’re pretty good.

If so, there was another discussion...

Somebody had this on Pinterest, or somewhere. One nice-looking crackerbox. Seemed like we were discussing these a while back, but I forgot where! Looks like it may have center point steering. Poor man's power steering.

That's about the way I got all those I found. A guy bought 2 trailers for storage. Took the axles off and put them on blocks on the ground. I got all 16 wheels and tires for something like $400. All of them were marked for drive or all-position use. All caps, but pretty good shape. I put 8 on the truck, but I let all the rest go when I sold that truck. In fact, part of the deal was that he HAD to take all those old 2-piece rims! LOL! Good luck hunting.

Exactly! That's all it was meant for. Hold the button in, get out of the road, and let the button go to lock it back down. Sometimes, there wasn't even enough air in that system to get them to release cleanly one time! That's how my old R was set up. In fact, all the R-models I drove in my youth had this setup. If/when it worked, it was a pretty nice system. No crawling under the truck to cage the spring just to move out of the road.

Found this the other night. The Quiring guys (from Highway Through Hell fame) apparently found themselves a D9G to help pull big stuff out with. They have posted several videos of the tractor in use. Seems like I read that they have both 8s and 9s. Interesting thing about this video is the tractor rearing up while pulling with the winch. I remember having that happen a lot when we used winches with the elevated roller over them (we called 'em "logging winches" because that's where they were at their best). Didn't happen when the cable came straight off the drum like most of our stuff was set up. That's a lot of nose up in the air! Looks like they could use new grouser bars on the tracks! They're kinda' worn down. Anyway, these are some pretty good clips to watch.

I hope you can do that. Much safer all-around. Not just better rims, but tubeless to boot. I haven't done hundreds like you...more like "dozens". Hated the 3-piece just a little less than the 2-piece! Like solid/tubeless better than either of them. My R600 had tube-type 10.00-20s on 2 piece wheels (rear), tube-type 10.00-20s on 3-piece wheels (front), and I found a butt-load of 11.00-22.5 tubeless on 1-piece wheels that I bought and put on the rear. They were all caps, but were better than what I had...and that got rid of those 2-piece rims. I've had a 2-piece come apart on me before. Luckily, no injuries. Probably because of the great deal of...uh...respect I had for them. Or, was that contempt? Luckily, never had a 3-piece separate on me. We had a local man killed here a few years ago. Was putting a 2-piece on his truck on the side of the road when it came apart. Bad day. Family man. Just trying to make a living. Hopefully, you can convert all yours and stay unmolested for years to come!
