Matt.. Before you order up any bearing kit or other parts for that unit, take a carefull look at the video from 20:02 to 20:20. Look in the gap between the input shaft first gear where the shaft passes through the housing from the gearbox side. When you were rocking the input shaft I could clearly see what I think was the Outer Track of the Input Shaft Bearing moving in the Bell housing. That would suggest that (water cooled) bearing has at some time has been seized and the entire bearing has been spinning in the housing. If I'm right that could mean the housing is scrap. I suggest you take a very close look and, if I were doing that job I would be doing a total strip down before ordering any new parts. I strongly suspect you might have much bigger problems than you think. I hope I'm wrong but I don't think so. I'm old school mechanic and long time retired, I'm also across the pond so can only watch not help. Best of luck and I hope I'm wrong but I don't think so.

[@BobbyTucker]

I don't want you to take this the wrong way but I've been a Mechanic at least 46 years, and I learned that if I'm not familiar with a certain type of repair, I take it to a professional. I'm sure you know what I'm trying to say. Good luck with that, my friend. I just wish I lived close enough to you where I could just drive to your place and help you with it, not for money but just to give me something to do, I'm retired and going stir-crazy, lol.

[@familytraditiontransportat7951]

Hey Matt, that input shaft is replaceable and it goes into a bearing at least on the newer stuff (70s up). When I pull a trans, I don't put it back in with a new clutch without changing that shaft. I've seen them twist off in the past, depending on how it's driven. I'd be changing the rear main seal and rear structure gaskets on that engine while it's out. Or better yet, update it to something more modern but still mechanical just to make the ole girl more usable. Can't wait for a Christine update! She looks good sitting there

[@G-Man-kc2nm]

Great advise.

[@louiradford7966]

Yes I'd have to agree with my learned friend better to replace the input shaft if possible and seals... thats coming from a tight fisted yorkshire man ( tight fisted means doesn't like spending money..) for you guys in America:-)

[@familytraditiontransportat7951]

@@koreywilliams4570 that style is pretty common on the smaller transmissions. I've done a few hot rods with that style hydraulic slave cylinder. Always good to change that stuff when it's out so you don't have to pull it again.

[@2dogstrucking107]

I think you have the skillset to do the Job Matt.

[@BlueDually4x4]

Its been a while since I have messed with a clutch, but the input has two wear spots because it is a double disk clutch. Considering it is only a single counter shaft transmission, your general gear box knowledge is plenty to rebuild it. A parts diagram or manual would get you through it. I don't know if your lowboy has a detachable neck or not, but making sure the PTO works would give you the ability to run the trailer's hydraulics if it has them. Having a wet kit on the truck for a winch or trailer functions would be handy for loading future projects up behind the Autocar.

[@kwoolguy]

It never hurts to have a second opinion and since you are working on a vintage truck it might save you some dollars to ask your friend to help.

[@dentoncustoms]

Before you drop money on rebuild kits etc, disassemble it and make sure you don't need a new shaft or a gear here & there. If you need hard parts, it'll make a good used transmission look attractive financially.

[@slateslavens]

I used to R&R these kinds of transmissions for a living. That wear on the input shaft is because the truck has a double-disc clutch. That input shaft is shot. I'd also be looking at the bushings and shafts for the clutch throw-out bearing fork. Please don't _ever_ lift one of those transmission like that ever again. If you're going to support it from the top like that, you need a strap under the front where the trans case meets the bell housing, and another under the rear about where the internal rib separates the front and rear internal sections. To reinstall it, I'd highly recommend using an appropriated rated 'engine-tilting' type device bolted to four corners of where the top cover bolts on. Getting that thing stabbed through _two_ clutch discs and the pilot bearing will be very difficult if you can't line the input shaft up _exactly._ You could probably handle the rebuild yourself, but I'd ask your friend if there are any tricky bits you need to be aware of.

[@carsonbarker2892]

[@dangerrangerlstc]

15 year Peterbilt tech here. 23:07 looks a lot like an Eaton clutch, if an older one. Should still be able to get replacements fairly easily. That works different from an automotive style clutch. Most cars are a push type where the throw out bearing pushes levers or fingers towards the engine to disengage the clutch. That style is a pull type clutch. The throw out bearing is a part of a clutch assembly. Forks pull the bearing towards the transmission to disengage the clutch. That may even have a clutch brake on the input shaft (didn't get a good look earlier in the video) that slows the input shaft so its easier to get in gear from a standstill. Looks to be a standard SAE bell housing design, one thats still used today. I would strongly suggest changing that input shaft. The splines may not be completely worn out, but there is a step worn in it that can keep the discs pushed against the flywheel and make it hard to get in gear. When you go back together, watch the fork as it goes in. Sometimes the fork won't roll around the front of the throw out bearing as it goes in and can get stuck in the clutch housing.
