seen on EBAY. Doea this belong to anyone here OR has anyone ever done this? Looks like a WD tranny mated to the rear of the WC one.

I like to know how the tractor could run any faster than any other WC. Both transmissions are facing forward so high gear is a 1 to 1 ratio. You can't go faster by adding transmissions without changing the gear ratio between the engine and the differential. The only way it could go faster is if you turned one transmission around backwards.

| I'd guess it has the second tranny sandwiched between the front (original) tranny and the WC rearend. No WD parts used. Low gear in front and low gear in the rear would be super super slow. Road gear in both would still yield a normal speed road gear. |

The rear transmission is backwards. Look inbetween the shifters you can see the rear transmissions gear selection legend. ------------- Randy Freshour,Member Indiana AC Partners, http://www.rumelyallis.com" rel="nofollow - http://www.rumelyallis.com |

I see it now by looking at the last picture. It looks like he scribed the shift pattern in. I saw that in the other pictures and thought it was the casting.

Very interesting? I never thought the WD or WD45 transmission would fit in there like that and bolt up. do you have to lenghten the frame rails?

Looking at it again I guess you wouldn't because your removing a section and adding the other tranny back in? How well does it really work is a good question?

The second transmission is not a WD or WD45 transmission. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

Doesn't the front transmission tower look shorter than the rear? Maybe the boot is on further so make it look shorter. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

Its not sold because the seller doesn't understand, that a clutch not releasing causing gear grinding is a separate problem from teeth missing from the ring gear. And the starter problem might be that the starter isn't mounted right. Since you can't shift on the go, starting out in the higher gears takes more torque at the clutch and the first transmission so has probably warped the clutch plate and maybe bent gear teeth in the first transmission both of which make it harder to shift.

Ah yes, this guy is an imbecile- look at his other auctions, and watch regularly. He knows darned well what year the tractor is- he parts out AC tractors daily. I'd be willing to bet that he actually reassembled some of this from some of the tractors he's parted. And don't conclude that he's unaware or misunderstanding of the situation- he's had more of these apart than you can imagine- torch, air-wrench, and skidloader are his primary tools. His standard modus operandi, is to buy a perfectly good running tractor, take photos of it, and then advertise all the valuable parts individually, by showing pictures of the entire tractor. He takes off what he can sell fast, and scraps the rest. I'm guessing that, from the lack of overspray management, that he hit this one with a can of touch-up, but saved a few bucks on running the pressure-washer... look at the easily-covered places, easily-removed areas, and of course, the areas most likely to accumulate dirt (the fuel tank seam) for indications. His ads all have the same key phrases: "This (was) from a good running tractor!" "LOOK at my photos. " "SELLING IT AS IS WHERE IS!!! NO REFUNDS OR EXCHANGES!!!" "Check out my other GREAT auctions" "email with ANY questions? " "If item is NOT removed within 60 days it is mine again!! I will either send you a bill for storage or resell the item!! Whichever I choose!! " I can guarantee this: Once he decides that he can't get his asking price for it, he'll take same photos you see here, and start offering the parts... and bone it out like all the rest. |

they put 2 transmission in the WC high crop to slow the tractor down i believe these have about a 2" spacer on the frame rails.I owned about 4 made this way still have 2.
looks like cut off the shift lever on the one that is painted up.

Richard, are those both WC tranny's then? It looks like the rear one on the other is "backwards" in there. Seems like it would be an easy way to get some gear ratio ------------- '40 WC puller,'50 WD puller,'50 M puller '65 770 Ollie *ALLIS EXPRESS contact* I can explain it to you, BUT I cannot understand it for you!! |

Yes they are both WC transmissions they are installed like normal WC.
they did this to slow the tractor speed down and also most of the WC high crop have a slower ring pinnion from the standard tractors.

not for sure if this was done by allis or by Thompson.
I lean more towards it being done by Thompson because it has a coupler between the the two transmission and Thompson did alot custom work on the allis tractors to make tractor work down south.

| I bought a 34 WC that had a second Transmission added like this. It was from a Chevrolet truck of a similar year. In this case a mechanic/machinist added it to slow the travel of the tractor because it had an allis mounted corn picker and the yield was to much for it to handle at factory ground speed in the 1970's. It would not go faster than factory as it was set up. As explained to me, high gear in a WC is same as direct connect so the two trannys as set up in my case would only go slower. I had 16 speeds and low-low was a creeper, high-high was no faster than normal. I don't think I even took a picture of it. Picker was shot and I put the tractor back to factory on full steel and it was the beginning of my unstyled WC collection. This was in the late 1980's. |
