How Practical? Building a T18A from parts

[IOPort51]

this is the thing I used to grab the bearings on the t-177, it was just big enough. It is a HF.

 

[Turbogus]

As far as the bearing extraction I think I'm going to just "p" on the fire and call the dog. I met with the new manager at Aamco and he'll pull the bearings for me and they have the gear to do it.
For the new bearings a shop that I'm friends with the owner just got a new press and he'll let me borrow after setting me up.

can you see the small spur gear on the end of the cluster gear?? what shape is it in? The reverse idler?

the condition of the cluster is pretty much the deciding factor of whether this is a Transmission rebuild or the exploration of the inner workings of a boat anchor.

 

[IOPort51]

I am guessing the beveled teeth on the 1st/second synchronizer mate with the reverse idler and there is not a lot of shifting into 1st gear unless you are pulling a 40 ft trailer with a Bradly fighting vehicle on it. this would be a good thing as those two parts can be found new.

After looking at this it looks like the cluster gear should be just fine and the 1st/2ndsincronizer and the reverse idler are, indeed, expendable. excellent engineering. this just keeps getting better.

 

[Turbogus]

Mainly I've got Rounding issues with those Synchronizer Assy. (2nd) and Countershaft gears (small end), no broken teeth but needs replacing just the same. Hoping to chat with Craig this afternoon if he's hoing to be around. I need a small road trip out his way anyway this 7 day work week grind is leaving me zombied.

The three main wearing points on one of these T-18 's especially off road is the 1st/Reverse sliding gear, the reverse Idler that only engages when put in reverse and the small gear on the rear of the counter shaft that only engages when in Low gear..........do to the fact there is no Synchronizer in either of these gears you must come to a complete stop before engaging or broken teeth will result. Any one of those Items that has damaged teeth will result in it jumping out of gear.

If the Jeep is 100% Off Road chipped teeth is , well lets say not as big an issue as I have seen some pretty creative things used like a bungy cord tied to the dash that holds the shifter forward when in Low gear......but we all know that is just a temporary fix.

One last thing , don't take your synchronizers apart unless you know what your doing or have them properly caged..........they are a bear to get all back together!

Thanks Tarry, I'm not even that far yet. Still have to take the Transmission down to get the bearings pulled. I'm very aware about the non synchro 1st on these, had an old '63 Chevy pickup that shifted the same way.

 

[IOPort51]

just for the sake of conversation, is there a front and back on the 1st/2nd syncronizer? Put the cherry edge of the teeth into play.

 

[Turbogus]

Stopped by Aamco the other day and they got the bearings pulled and for gratis, if I can make some this season, Phil's going to get some of my Applejack come Christmas.

My adventure into T-18 land keeps getting more and more interesting. Identification is difficult and information is sketchy. At this point the casting number and the top cover bolt pattern are indicating a Ford but it has the bell to Transmission bolt pattern, the front adapter and the drivers side PTO of a Jeep. I removed it from a 1975 CJ5 (like that counts for anything) but the over and down reverse is indicating a 79. The 79 should be wide ratio but I checked when I bought it and it is a 4.20. I guess it is time I pulled it out of the barn and put it someplace I can clean it up and look at it closer.

The T-18 may be a heck of a Transmission but it is a lot more weight than the T-150 . kind of like carrying a couple of fair sized passengers all the time . Should smooth the ride out a bit.

IO, I'm sure you know, but check the length of the input shaft, might help with further identification.
I dont know what a T-150 weighs, but I do know the T-18 /19's weigh in 75 lbs more than a T-5

 

[IOPort51]

about 60 pounds more than a T-150 so I guess I exaggerate a bit but still not looking forward to wrestling with it.

When I bought it it was behind a AMC 304 so input should be good but I did not look at the pilot bushing and have not measured the input shaft, good point.

I think it is safe to say it is not a FSJ.

I just got a Tremec book (Bulletin LD18-0410-0199) and while it covers a few of the models of T 18s It's wonderfully illustrated and the text is straighforward enough (with pn.s) for even a neophyte like me.

Turbogus,
A lot of some ones wrote books , Granville King told it as easy as could be for the Jeeper in us all (R.I.P. GK), the best one I have is a Mitchell that covers all the light truck transmissions. Your Tremac Manual wasn`t to expensive was it?
The Pictures I sent you were from the AMC Jeep Parts Manual 1981-1984 which shows you that Jeep still sold T-18 `s as a dealer option thru 1986 for the Dana 300 . Only worked on a couple of CJ`s in the 80`s with the dealer option T-18 and one had the Dana 44 rear option NT rear axle. Keep us posted on your tear down, looking forward to seeing the other gears, and the condition of the cluster shaft, main shaft & input shaft hard surfaces. The one I was going to sell you was a International Scout stuffed in a Ford case (did not have empty Jeep case at the time) with Jeep input & bearing retainer. Don`t feel bad the most expensive Transmission is a metric Munci (aka Toyota Land Cruiser) were the gears start at $$$$.
P.S. IO started his own post so he should not hijack yours
P.S.S. Here is the picture at my place, still can`t believe your friend sleeping in a CJ5 .

I have this book. hoping for something with bearing sizes and tooth count. So far I have found nothing related to these part numbers. I will have to check out the King and the Mitchel. If you wanted to play mix and match you need a bit more than a lot of the exploded view of one page of illustration. excellent cut and paste job.

that said, this book is most definitely worth the price the illustrations are clear and sized so they can be read by someone other than an eagle. the instructions clear and is a great aid to dis assembly, inspection, and re assembly.

I consider this book a worthwhile possession. but it just stops when things getting really interesting.

Gotcha IO,
You guy`s are looking for a master catalog like what the bearing dealer and rebuilders have, and I have one if I can ever find it. Like a 208 bearing has xx" for A and xx" for C dimensions and gear 1 has xx teeth xx diameter and cross references to x & y brands.
The Mitchell is a big Transmission book like the FS Manual, but covers all transmissions Turbos, C-4`s, Warners, Muncie-Saginaws, Fullers, New Process etc... The T-18 section is only 6 pages, if you have one fine, not worth buying unless you do a lot of Transmission work on all domestic light trucks. Can post you the pages when I get done working on the 2A later tonight. Have a few parts manuals I will look thru also. Have a disc will look on it to.

Can not remove pages from binder, it has been together since the 70`s, do not want to destroy it, took this picture. Wanted to remove & scan, will take pictures in day light tomorrow, been high 80`s & 90`s for weeks now. Damn field burning made it smoky today. Right in the middle of the grass seed capital of the world.
I also found my discs from Bell & Howell, Chrysler Electronics Parts Catalog, except my computer does not have P.A.I.S. (Parts Access Information System) that was on my desk top computer that fried, will try to get that also.
Another day, another repair.

Here is the Mitchell.
