Weird T98

Anyone ever heard of a T98 with a 1-3/8 input shaft and a circle SAE bellhousing? I came across a weird highway mower rig from maybe the 60s that had one backed by a spicer 18. No motor and what looks like M725 axles. Weird rig.

 

T98 was used in many many industrial applications.
So oddball shaft and gear configurations are not uncommon.
Some applications even had the gear helical angles reversed.
1-3/8" maindrive (input) was also used on early 1950's Ford T98.

 

Are Willys compatible input shafts hard to find?

I'm thinking about picking this thing up.

 

You'll never find the correct 15/16" inch input shaft without the rest of the transmission.
At least I've never come across one.

 

Turns out it's a T9?

WG Div T9-1P W1

It has what appears to be a Spicer 18 on the back directly mated.

 

WG Div is Warner Gear Division of Borg-Warner. The rest of the numbers do not make sense in the Jeep world AFAIK. The M7x5 uses a T98 but with a divorced NP200 transfer case.

 

T-9s were commonly used in the '40s by Ford and Studebaker trucks before they switched to the synchronized T-98 in the '50s. T-9s are not synchronized at all.

 

Thanks for the feedback guys.

Are there decent parts interchange between the T-9 and T-98 gearboxes?

From the outside, they really look almost identicle, specially with a Spicer 18 on the back.

 

They were apparently also used back into the '30s and by many more manufacturers like International Harvester, Diamond T, and DIVCO. I would hazard a guess that the major difference is the synchronization of 2nd through 4th gear.

 

Unlikely there is much in common, since the design of a crash box is completely different from a synchromesh (aka constant mesh) transmission - sliding gears vs. sliding collars. To shift a crash box, you had to learn to match speeds through shift timing and double clutching. Small parts, bearings maybe ... but the stuff that most wears out (blocking rings, synchro collars, etc.) is simply missing from a crash box. Manual transmission - Wikipedia

 

Fair enough. more digging is in order I think. Thanks!

 

I do have a few bellhousings to size the front up. This is not drilled on the ears like a Ford T18 but it does have ears.

 

I'll play around with the bells tonight to see if the Willys bell fits the holes this thing is drilled for already. Eyeballing them, they might be close.

Assuming the stickout length is either corrected or works as is, and assuming I get a throwout that fits a 1.375, think something like this disc work with a later F134 9.25" flywheel and pressure plate setup?

Top holes were close. Bottom holes are not even remotely close.
