I am in the process of building a outlaw puller with a 300 ci Ford truck engine WE hope to produce over 150 hp and use the stock automatic trans connected to possibly a wd drive train
Will the tranny and rear end of the wd hold up to this much power?
I am in the early stages and accumulating parts as I go so if not I can chang directions

I'm not sure I would even use the tractor tranny I might just use the automatic that is with the truck engine and shaft back to the differential
I just don't know how much the old diffs can take

The WD and WD45 list different differentials..The finals are listed under the same replacement part numbers for both tractors..If these numbers superceeded numerous other numbers,?? good question. As far as the D17 goes,,I don't have a parts breakdown for a D17,,but remember, there are four different series of D17s..Telling what was changed when on those tractors, and if any W series parts were used, would require the parts books for a D17..One trick to reading a parts book is understanding the reasoning for superceeding a number...Often, a new part will replace several older parts variations..That don't mean the older variations will interchange with each other...But the replacement part is acceptable for use in both..Sometimes the difference could be less obvious, such as the hardening process used in the steel..

Thanks for the info . The book on the model I"m building says it is 120 hp stock but who knows what it can produce . I haven"t got the tractor yet but iI might go for a WD45 instead . Like you said it"s just fun

The WD45 transmission is stronger at the gear teeth but may pop out of gear easier under that kind of hp especially if it has alot of hours on it. Old WD and WC transmissions were very tough though.

Good point to bring up..I went through my WD45 transmission back in 1978 for that reason..The transmission was wore out from being used as a Norwegian Payloader,(trip bucket loader) with alot of shifting wear on the shift collars..I replaced the worn collars and some associated gears at that time..since then, Auntie Allis has never poped out of gear, even pulling 4-16"..No, I bought that plow because the price was right..But if I was going to build a puller out of a 50or60some year old tractor, I would be looking very closely at the trans, diff and finals.. The old WC , with that simplified rear end design,, has many options...One of my wild daydreams would be to take a late WC, and mount a 350 chev,turbo 350trans and a transfer case reworked with a deep reduction kit..I would change the angle on the transfer case to align with the frame rails and the rear end on the WC..Of course, I would have to get the radiator and hood and fenders for an old unstyled WC to cover this..And DEFENITELY have that crank sticking out the front...I'd also put an EPA sticker on the fuel tank that said unleaded fuel only..And I would have to have spoked wheels, front and rear..I just hope I still have room for a mounted corn cultivator,, I will need the extra weight..

the predecessor of the 300 was the 240 and they came stock with 159HP...i built a '65 F100 years ago that was pushin 280 HP out of them 6 holes...better start stockin up on differential parts.

They do have a good reputation,,,but the WD45 would be a little beefier one to start with..this will definitely void the warranty, tho---opps, excuse me, my elephant is sleeping on the roof again, and its time for him to go get the mail...the hindsight will be 20-20 on that one,enjoy your project..

Check the parts book for numbers- see if there is a difference between WD, WD45, D17....regarding gear numbers. Friend of mine says they are the same. I really would like to know.

yes, they are different.... The majority of the WDs had the early transmission, which had a straight shift lever. This early transmission has straight cut teeth on the gears...At WD serial number 127007 a new design transmission,known as the WD45 transmission with it's curved shift lever, was used in the remaining WDs produced..The Later transmission has helical cut teeth on the gears..The transmission and rear end housings, along with some rear end components, also are different....some of the older WDs also had a difference in final drive housings, (1950ish)The WD45 also had a beefier axel. The newest number in my parts book for the later axel superceeded the original axel's number, meaning the last replacement axel can be used in either tractor...Anouther change occured to the engine clutch input shaft..I know of three different shaft numbers and seal arrangements,, But the last parts book has superceeded them to one shaft, and three seal numbers..All of there changes did not occur at the same time.. The WD45 is also listed as having wider rims. There is more than what meets the eye...and the ears, the WD45 transmission is much more quiet.

Sorry I wasn't more clear- inquiry was in regard to the differential and final drive gears. Often wondered what the parts book numbers would show- maybe ne meant that D17 parts would fit in a WD.
