T98 parts availability?

My brother has a T98 that he needs some parts for repairing it. I've already tried a "T98" search and didn't come up with anything. Can somebody point me to where I(he) can buy the parts?

 

What's the T98 mated to ?
I have a bunch of OEM NOS T98 stuff.
What you need ?
PM me I'll answer you later. Gotta go....

 

I'd talk to Ken.

T98 stuff isn't easy to find.

 

Try these guys

i got a t98 outta an m715. was nothing wrong with it, new owner wanted a chevy engine / auto trans so out it came. can have it if you want.

 

That offer blows me away Andy, thank you for that.

One of the items that my brother needs is the input shaft as the one he has is chewed up from the previous owner running it without the pilot bearing in the clutch. The M715 version was mated to the NP200 and has an input shaft diameter of 1 1/8". The "Jeep CJ" version mated up to the Spicer 18 and had an input shaft diameter of 15/16", so it is not a direct bolt replacement.

The question now is what else is different about the two versions, ie, other than the input shaft, could my brother use some of the other parts inside the M715 trans in the "Jeep CJ" trans?

PM's sent to both Andy and Ken.

 

1967-1968 M715 and all pre 1969 CJ T98's are 100% identicle excepting.
Maindrive gears (MDG's)
Mainshafts.
Front bearing retainers
Bellhousing adapter plate (required with CJ)
Transfer case adapter plate (required with CJ)
And of course... the CJ uses a mainshaft output gear while the M715 uses a mainshaft output yoke Shift Also the shift canes may vary a little in length.

A CJ MDG will be near impossible to locate without a complete CJ Transmission.
Try HERM for that...

 

you can weld that pilot nose up on that shaft & have it ground down, either on a crank grinding machine or on a lathe with a grinding attachment. i once ground a 12 bolt chevy car pinion down to fit in a 12 bolt chevy truck housing.

 

Re what Andy wrote, I'd take the input/MDG to a local automotive machine shop and see what they can do for you. Technically, it should not be difficult as long as welding on the pilot does not do something bad to the integrity of the steel. Like Ken wrote, I'd expect it would be very difficult to find a replacement gear without a transmission attached.

Another possibility would be to grind the tip a little undersized, and make a custom pilot bushing. The obvious approach would be to find a bushing that is oversize and trim it. But you may be able to make a complete new bushing from sintered bronze stock. Novak might be able to help with this - they make bushings for their conversion kits, and they could advise you or make the part.

 

Further info from the brother. This is a copy and paste from the message he sent to me today.

"Looks like I need the main drive gear--( 4th gear ), direct & 3rd clutch sleeve, 2nd gear and the counter shaft itself, NOT the counter shaft gear cluster."

I'm not a trans expert but I know most of you are. I'm figuring (from posts above) the main drive gear is the hard one to find. Correct me if I'm wrong. What about the other parts listed here?

The T98 he has came out of a CJ-5, F134, Spicer D-18 configuration.

Will go ahead and PM Ken now as well.

 

The T-98 counter gear shaft is the same between T-18 and T-98. At least the ones I've rebuilt are.
To cut down a main drive gear/input shaft properly it needs annealed first, machined, then re heat treated. These are not through hardened but are surface hardened. Grind/machine them without doing this and you are machining away the heat treating so will end up with a soft shaft that can bend under load and at the least will wear quickly.
