The passenger side was 40 gal, the drivers was 50 gal. since there was no stack bracket in the way. This was square tanks, not sure about round tanks.

Great info. Thanks. I know 20 yrs ago when I was working on my wiper control knob that there is different variations. The air lines were different and it wouldn't function correctly. I ended up sending mine back to Barry and just putting a new o-ring in mine to help seal it up.

This ∆∆∆∆∆∆. I think that is what the most critical aspect is. The tires do NOT need to be deflated. Those clamps will be wedged tight and smacking then loose before removing the nut is the only real danger of taking a dayton rim off. The thread size for the nut is what you need to know the torque for. Some are larger then others and this would take more torque. I never really torqued mine, just the 3/4" impact going around in cross pattern after confirming the rim runs true. I did watch my local tire shop torque them the one time they put new fronts on.

I was not referring to the wrench size. I was noting the actual thread size. A tape measure is more then close enough to guess. It is 1/4" steps in sizes so you can eye that close enough.

Likely 1/2" pipe. It's all std stuff. For a simple check, if the Outside diameter of the thread fitting is 3/4", its 1/2" pipe. Pipe dimensions go by the INSIDEof the pipe, so it's like 1/4" bigger then the actual size. So a 3/4" pipe is about 1" in diameter, and so on.

Yup. Measure 6 times, cut once.

Just do it! I took the leap of faith and it turned out pretty nice.

I bolted jakes on my 237, no problems. I'm trying to recall it used longer head studs in certain locations? Heck, been 5? yrs so I can't recall. But if you are swapping between engines, then you should have everything to do it and have two running engines.

Yes, the early valve stem was larger and took a different disc. My 237 was like that. That disc is NLA. The later, smaller stem is available.

Should bolt on. You can still get full kits for them....just real pricey. I went through mine when I bought them used(old and unknown condition). Bought everything through local Mack dealer.

Should be the same as any other B tanks as far as I know. They have drawings they will send you to sign off before they build them. I tell this story every time someone looks for tanks. I had Alumitank build my (2) 40 gal tanks to match exactly the stock tank. Their version the step is too high. Ask for the 40 gal tank they made for "General Plastex"(co. I work for). That is the more correct version. Then have them duplicate it for the longer 50 gal tank.

I have three sticks now. It is a spicer 4 spd aux with deep under. I run it in direct 99% of the time. The OD is for really stretching my legs on the highway. The deep under is for tight manuevering. I don't try moving three sticks. The split in the spicer is the same as my triplex compound. Up in one and down in the other just keeps you in the same gear. Here is a video I made a couple years ago and I do use OD in the spicer once. Sorry it's a bit dark i needed to get a better angle next time.

Yes, absolutely.

Is that what is going on? Thought I saw something online joking around about him being sick. Don't watch the news so didn't know what the joke was. I see now.

I got home last summer to see my box mangled up and the post swung around at a 45* angle to the road. I was like WTF??? I was pissed. The school busses drive thru my yard to cut the corner so I figured as such. I get around to the back of the house and find a new mailbox sitting by the door and a note from the mailman apologizing for doing it. Seems he forgot to close the door before pulling away and it spun the pole around. I tried manually turning that pipe. Nope. I had to get the Mack out and put a chain on it to swivel it back straight. Then a new board to attach the new box. Looks like it never got hit. Still waiting to put some 2x4s in the yard with 16 penny spikes to flatten the tires on those damn school busses. The grass grows back all summer, then it's all tore up for the rest of school time. MFrs. I put some metal fence stakes up around the corner and the next day they were bent into the ground by the first bus.

I just did a quick search on ebay. Lots of choices.

Very similar to my Bentz bunk. If I recall the latches were similar to AMC cars. Might look there for something?

Interesting project. I'm curious now if those were direct drive, full time pumps(likely).

Fantastic work! I love that chase seen. I do have to laugh how slow that old chebby pickup is if that DM could keep up. LOL.

Mine had 4.62 also, now 4.11. I did the gears before the 237 install or I would have stayed with the 3.70s that were in the air ride rear when I bought it. Single od triplex, 4.10, 11r22, runs 65 at around 1800.

They had Cummins laid on their sides.

Would be cool to put in my B model. The old 237 would never hurt it. But distance and cost to "fix" would likely make it a moot point. I'd love to learn how to tear into one.

I took a quick trip in Kens MH a couple years back while at Gerharts show. Short, spring ride single axle wasn't hateful at all. Much nicer then my B model!!

I'd go by 673C on front cover. Valve covers are easy to swap. Someone could have put oil filter and cooler on from a 237? I put spin on filters on my 673 NA motor. Bolts right on.

Neat piece for sure. I saw it come up on facebook a few days back. Value is a hard thing to place on a vehicle. A lot depends on your location and who happens to want it. Just saw a post on FB about a full frame off B61 sold for $15k(A steal).
