Allis Chalmers WD

[DValentine]

Hello to all tractor nuts out there. I just bought a '52 WD today. Don't know much about it. It has good tin, tires and rims. It has a WD 45 engine in it. The thing that I can't figure out is the clutches. It has a pressure plate clutch operated by foot control, then a hand operated clutch that is separate from the foot control.



It has a loader on the front with a funny home brewed hydraulic control to split the loader from the three point hitch control.



Anyway, it seem to run well and is in good shape. I just want to know more about how it works (internally) and some of the quirks of this fine machine.



Thanks all



Dave

Hello????



No tractor nuts out there?



OH well.

The foot operated clutch is a dry clutch. It is used when you are engaging/ disengaging the PTO, as well as operates the traction clutch. The hand clutch operates the traction clutch as well, and is best to use when inching forward or backwards. It is in oil, and doesn't get as hot.



They are nice little tractors. We have 6 of them around here. One is a dedicated tree spraying tractor, and the others mostly run augers, and other odd jobs.



If you haven't, make sure to clean the oilbath air filter, and put in fresh oil. Use the same type as the engine crankcase. Make the oil in the drop boxes is clean, and no water in there. Gets nasty over time. 80W-90, IIRC. And the hydraulics take straight 20W.



Pop the cover off of the steering box at the front of the tractor, and see if it needs any grease. I use John Deere cornhead grease in ours.



To grease the throw-out bearing of the traction clutch, you will see a short little lever with a notch on the end. The notch is used to hold the clutch pedal down, so that the you can reach the zerk.



If it hasn't been converted to 12v, the headlight switch also controls the rate of charge from the generator. I'll have to look in the manual for sure, but IIRC, pulling the switch up to the first position is no lights, slow charge, and the second is lights on, fast charge.

Thanks Bmoeller, I knew there are some guys here who know something of these gems.



I have read some forums on the AC..... not as easy to use as this forum to search for things. I got to thinking about the clutch system... . two clutches... one wet one dry. The dry one is ahead of the pto, which allows this to be live even when the tractor direction is controlled by the wet clutch.



What does IIRC stand for?



Drop boxes are what? ---the rear axle? What kind of oil in the wet clutch?



It is 12 volt, with a generator.



The hydraulic pump is integral to the machine. It needs some replumbing to make it more user friendly. There is a ball valve mounted off the pump itself, and I can't reach it to change from bucket to 3 point while sitting on the seat.



the dry clutch had a lever that sat behind the foot lever... . not sure what it was for... . it broke off the stud the day I test drove it. Is that the lever you mentioned, used in greasing the throwout bearing?





Thanks for the help

How bout a pic.

 

[DValentine]

Give me some time.....



The tractor came with a house the wife and I are buying. I forgot to get some picts the other day when the owner and I were dickering over price.



We close on the house in two weeks and will get some when all the paper work gets settled.



The house is 100 miles away.



Thanks for the interst.

As long as the PTO is already engaged, it will be a "live" PTO, while using the hand clutch. However, the foot operated clutch must be used (and while sitting still), to engage the PTO.

What does IIRC stand for?

If I Remember Correctly.

Drop boxes are what? ---the rear axle?



Yes, they are part of the rear axle. They are bolted to the ends of the axles, in which the axle shafts are attached to.

What kind of oil in the wet clutch?

I need to look in the book to make sure, but I think the hydraulic oil is the same oil used with that clutch.

It is 12 volt, with a generator.

That is good. The 6 volt systems are really slow sometimes.

the dry clutch had a lever that sat behind the foot lever... . not sure what it was for... . it broke off the stud the day I test drove it. Is that the lever you mentioned, used in greasing the throwout bearing?

Yes, that is the one.

 

[DValentine]

Thanks for the info...



I'll be trying to find manual for this thing... . I think they are available on line from some of the antique tractor parts houses.



I'll get some picts next time I see the old girl.

I love it, Dave says "I bought a tractor today" Most people away from TDR would have said "I bought a house today" and a tractor comes with it. :-laf



That's one of the things I love about the people here

Dave, ya got a dandy tractor in that AC-WD, specially w/the 45 engine. I was raised on the old AC's C, CA, WC, WD, WD45. I also worked for the local AC distributor for three years right out of high school, 1969-1972, in Ashland, Montana, same county as yours. Which way from Forsyth is the 100 miles, Powder River County, perhaps?

Ah---Ashland... . that must have a great place to grow up in. Does your family still have land down that way?



I'll be picking your collective heads for knowledge. It will be a while before I get to spend a lot of time with the WD, as I am trying to get my place in Forsyth together to sell.



The new house is in Laurel, a compromise with wife who lives and works in Cody, Wy.

It will be a slow move for both of us. I'll be working a shut down in Colstrip this spring and won't have much time to play with the old girl. Once I get my stuff moved and settled in, the I'll try to get aquainted with her.



Is there any adjustment for the clutches?

I read some where about a screw on the side of the hydraulic pump to set flow volume?





I have much to learn... . thanks all



Dave

Should be. Never done it though. I'll have to look in the book. I've only had to adjust the brakes.

I'm not sure. Never messed with it.

Dave, the "ah Ashland" is funny, i like that. When my dad died in 75, mom sold out. We had a small farm/ranch in Sonnette,Mt. that is in Powder River County. I lived in Ashland about 7 years, then moved here in 1977. My younger brother still lives there and now owns the old AC dealer where I worked. It was down graded to just Hardware and Repair when he took over. If ya get up that way, stop in and tell him ya talked to me on this site.



His outfit is right on main can't miss it, called Fred's Hardware. the left side of the street as you are east bound. I will call and ask him if any old books survived the downgrade.

You should be able to get a manual on ebay, or get a reprint form an agco dealer reasonable. We have 6 wd's , and wd45's in our family. Id suggest getting a manual, and start hanging around the allis website , and youll learn a bunch very quickly. Be sure to to check transmission/ and differential fluid as mentioned above I use 80 w 90. Fills are located on left side in the foot clutch area. The one with the dipstick is the hydraulic. I use universal hydraulic fluid in mine, but originally they used sae 20 motor oil, like mentioned above, but that was before better oils came along. I have also seen auto trans fluid used with no problems in the hydraulics. I think the lever behind the foot clutch you're refereing to is a foot clutch lock out. This is used to depress the foot clutch , while hand crank starting, Its for safety , and make it easier to crank over.

That's what it is... I think you have it.



Nick-If I get up that way, I'll look him up. It is funny how small this world is, when a guy starts nosing around, dropping names



Thanks guys, for all the input. I am sure I'll ask more questions as I go along. We are signing papers on the house on friday, but won't be moving in until late this spring or early summer. It turns out, one of the neighbors is a tractor nut, rebuilds/restores so he might have some pointers as well.



I'll post picts when I get them... . thanks all.



I haven't found any AC discussion forums like this one (TDR). Not easy to navigate, or to find-Search- for old threads. Any advice



Dave

 

[fbaurley]

Try a search for the unofficial allis website. Its a good sized discussion forum for AC tractors. http://www.allischalmers.com/. I beleive there is an AGCO dealer In Billings. Agco is the current "allis chalmers" I used to do some work out at Stillwater Mine In Nye , and would drive through Laurel every time I went out there.

Thanks for the support.
