Something a long these lines? This for 18 spd. https://www.vanderhaags.com/detailview.php?manufacturer=fuller&model=rtlo18918b&inventorytype=transmission-clutch-housing&partnumber=K3672&wcf=parentmodel I guess you have to buy it for the particular model transmission? If I have a choice, I am going for something with a double OD.

My truck is together so there is no way to measure anything. Oops, I see I typed #2 up above. That wrong. I don't need mounts on the bell housing. I am going to have to fab up something else, maybe something underslung near the back of the box? That will have to be done after I get a transmission picked

So, if I start to research a 13 spd, try to locate one with side mounts. Then work on #1 bell with push clutch? Or parts for such. I can convert my linkage to pull, I have the technology....a lathe and a welder. Heck find me a fresh rebuilt triplex and I would be just as happy. I could try to rebuild mine, I heard most all bearings are available but if there is gear or slider issues I will be in a bad way finding parts.

Ok, so now it is all about the transmission Bell housing and trying to find a 13 spd with transmission mounts on the side of the box. Apparently they did offer it because they did come in R models. Finding that case may be hens teeth. If the Bell housing has mounts built in, it is not needed. Ya, I was thinking the same thing. Or come up with 3/8" shoulder bolts that have 7/16 shoulder and use them. Not a real concern though.

Never mind. Can't delete the ad.

Ok. My flywheel housing is about 6" ish. The transmission Bell housing is 6 1/4". You mentioned #1 SAE. But mine has 3/8" bolts like a #2?? So, the flywheel bells are the same, it is only the transmission side that is deeper. My dual disc flywheel stuck out about 1" from housing. I assumed that would be wrong. Guess not? You can see it near the end of my start up video. https://youtu.be/dkojHq2QnyI?si=I_sGrLVA3SuGBH-D Awesome, thank you for clearing that up. This gives me better insight on what needs to happen.

I made a lot of assumptions when I started this. I assumed that the deeper flywheel would need a deeper housing? When I started this 237 using a dual disc flywheel, it stuck out the end of housing about an inch. I assumed it would deep a deeper housing. I'm wrong? That saves a lot of messing around(removing and dialing in new one). Can someone measure their Mack flywheel housing and I can compare it. Mine has lower right starter, like a B model so I assumed it might be incorrect. I think most R models are upper left? Or maybe this is just another quirk of it being from a fire engine? The more times I get into finding information about this, the more I learn that I don't know much.

Heck, If I could just use my single push and get a shorter input for a 13 spd that would make things a HUGE amount easier. It would be a bolt in. I have a 2" input currently. Only reason is my triplex is just gone and want something that is smooth, quiet and stays in gear. I just need to find a box that has side mounts for a Mack application. I could even live with a 10 spd if I had to. Just needs OD.

Interesting. I'm not versed in all this so it seems strange it was a twin disc? My 237 came from a fire truck and was a single disc. I want to upgrade so I can put a 13 spd in it.

Need a dual disc flywheel housing for 237-285. Closer to NE Ohio the better.

How easy to get? Part number? Someone have one laying around close to NE Ohio? I need to change out my single disc flywheel so I can upgrade my transmission. I have a flywheel already.

Mark? I met him at South Bend. Very cool piece. V8 cat if I recall?

A B model for more comfort? That is going in the wrong direction. Lol. My heat works great in the summer and the AC works good in the winter. 😂. Unless you do a lot of upgrades, they are drafty old trucks(kinda like an army truck). I've used mine for the last 23 summers to drag my race car around the East Coast. I added a 237 for some power, cruise control, AC, air steering, air ride. Still rides like a slow moving 50's buckboard. You will miss that 400 Cummins! I would recommend an R model with some factory power.

My hand pump clamp never comes loose? Just light snug and it is good. Never really use it much. I ran mine low on fuel once, sucked air and stalled. I pumped it up for 20-30 seconds and my air starter lit it off easily. Stumbled a few seconds and then was fine. I was on the side of road with no air available, so I only had once chance to get it running.

Bob's eyeing up that U hood. 😆. You'll see his post below about his start on it now that he is retired and bored to death. 😜 Nice project.

I keep my head up but we all know what happened the last time. We were in a good place but "they" couldn't handle it and just made a mess anyplace they could(of course in their cities).

That scene is from Planes, Trains,and automobiles. I think from where they spun out on the highway.

Depending on the OD, it could be 12 pitch which you could buy a fine thread bolt, cut it off and mill a slot. Presto, replacement.

Found this one finally. https://www.facebook.com/reel/755480683425230?mibextid=rS40aB7S9Ucbxw6v

I've dreaded this whole mess. They win, we're screwed. We win and they make our lives hell for 4 yrs. Who wins?? No one.

The upper port, in the head, is the output. The lower port just below is the intake. Mine has a small box with foam filter bolted directly to compressor . Many older trucks had rubber hose coming from air cleaner tube up at engine. This is picture of my 237 before stripping it down and getting it installed. I already removed the fittings from the compressor. I actually installed the compressor from my 673 because it was already rebuilt.

I realize there is no vacuum,but I was looking at it backwards. It is actually leaking boost like others said. Unless there is a poppet valve or regulator in that fitting. Sounds like the previous owner might have just made a mistake installing it??

Besides the libtards burning towns and tearing down statues....... 🙄
