I pulled this 5 speed OD off a 292 Y block from a 1960 F600. Was told the motor was swapped at some point. It has a Spicer PTO gearbox. The only tag on it tells me nothing that I can make sense of. Is this a Clark or New Proccess transmission and what model? Thank you.

 

Looking at the shop manual I would say it looks like a 5-Speed Medium Duty Clark. The three nubs on the cover behind the shift lever are a clue. The heavy duty only has two of those nubs and the extra heavy duty cover looks altogether different. If you don't have a shop manual, I would highly recommend one. They have a lot of info you would be interested in.
By the way, that sure cleaned up nice! Even got a starter!

 

The link in this thread shows the case number, 224716, as being used for several Clark 5 speeds, direct and over. The pertinent info does not copy and paste well. Scroll down to page 3 and look to the right of center for "CASE". You will find your number and the associated transmission models to the left.

I can move you to Large Truck if need be or if you want.

 

I agree, 251VO. Nice piece, and very desirable if it doesn't need a rebuild.

 

Really good find. What you going to do with it? I have been looking for one to put in my 60 3/4 ton 4x4.

 

Have you put this OD beauty to use? If not, I have interest.

 

It looks like the pto on my t98. I have a blank off plate if you want to trade and if they are the same.
