Just picked this up from a tractor buddy of mine. Its definitely a t92, and appears to be a Crosley or B/W varient??

I haven't messed with it other then making sure the output wasnt sloppy, and main trans shifted.

He had told me it came with a clutch over the phone, but after getting it im thinking its a 2 speed however, im not sure what it is? I would think an aux box would be on the output side, but this unit is definitely on the input side, and appears to be cast aluminum with a keyed input shaft.

Ok transmission gurus, what is this unit on the input side of the 92?

Looks like it might be a wet PTO clutch. You should drain it and pull the side cover.

Third gear is direct drive so you could count turns to see if there is any reduction or increase.Pretty interesting piece.

Correct, Ill try and check it out.

Yes it is unusual for sure, cant find anything on it!

As stated earlier, I hope Classic is right about it being a clutch, but I aint never seen 1 of these.

If it is a clutch, I might have a use for it. Im also going to have to find a female splined shaft, or yoke for the output side.

Wonder what input shaft the trans has?  Some had short one with no clutch option and just used a gear there or pulleys like on Speedex and others. Have no idea on the other case. Looks like a big engagement lever and is that a LOCK tin that drops over the moving shaft then to lock into place?  That is also ONE beefy shifter shaft coming from the trans, but short. I think his  is an item you set trans speed and then interlock other to operate what-ever and not really made for shifting on the go and such, like on a tractor. Must be some sort of machinery drive, like a bailer  or road work machine or such?

Well folks, the wait is over. It is........in 3, 2, 1, a wet clutch.

I stopped at a buddies shop today, and pulled a side cover to have a look see, and took a couple pics.

This having a clutch is actually good news as i wanted this transmission for my Bolens 600, cause I think that one is going under the knife anyway.

I still dont know what it is from, but I think it will work.

Thanks for all the imput guys, Cheers!

Might be military.I bought a whole pallet of surplus T-92 transmissions with a different shifter on them.

OK, guess I don't get what a WET clutch is or how it works. Some cones that slide together?  Must be some way to go from stop to start w/out instant lock-up. Don't know what it is.

A wet clutch is similar to a dry clutch except it runs in oil.  If your car has an automatic transmission it has several wet clutches.

On a motorcycle (and I expect most wet clutches) there are multiple clutch plates stacked together around a central shaft.  Every other plate is splined to the central shaft.  The other plates are splined to a basket around the assembly.  When the pressure plate compresses the stack the central shaft is locked to the basket.

 

Here is a picture of motorcycle clutch plates: 71-110.jpg

The basket in turn is connected to another shaft. 

On motorcycles the outer basket is connected to the crankshaft by either a ring gear or chain.  The center shaft is the input shaft to the transmission.

 

But on a motorcycle the input and output shafts are on the same side.  The clutch pictured has the output opposite the input.  I suspect in that case the basked itself is splined directly to the shaft.

 

I suspect the clutch on the T-92 is more like this one for a Kubota tractor: wetclutchpack.jpg

Nice thing is, I could put this on just about anything.

Not to steer off topic, but I have been looking at PTO yokes, and seems that getting something to fit shouldn't be a problem.
