wd trouble

Well, I got my  formerly seized wd runnng today, GREAT! No oil pressure, BAD! Pulled the pan off and the oil pump drive gear is history...So I need a cam, bearings and advice on how to change it. Can I do it with the engine still in the tractor, pull the rad etc.? Or does the engine have to come out? Thanks in advance, I was up, now, down, feeling pretty defeated, Trev.

I understand what you are saying, and, in a more perfect world thats exactly what I would do...But, I dont have the cash to do it right, so Im looking for a cam and advice on how to change it out, thanks, Trev.

Remove valve cover, rockers, and push rods. Use wooden dowls and push into lifters, (then get your wife's laundry bag and use her cloth pins) to hold the lifters up while you change the cam.  MACK

The engine wiil need to come out. The lifters will not stay in place with the engine upright. When I removed the cam in My CA. I just took the engine out and removed the rockers and push rods turned it upside down on the engine stand and pulled the cam. Gravity held the cam followers out of the way. Replaced the drive pin in the Cam with a roll pin and put it back together. I also replaced the oil pump pickup when it was upside down. Its almost imposable to get the pan back on under the tractor. Very easy when itys on the stand. In 4 hours I had it back in the tractor and running again. When we pulled the engine in my dads WD many years ago  We torched a notch out of the top right side frame rail so the engie would llift out between the frame rails without all the twisting and leaning to get it past the rail.

Thanks Lonn. I will change the bearings while Im in there, and look for a new oil pump. I talked to a couple experienced Canadians today (in their 80s) and they recomended the same method as You and Mack. I have no reason to think it wont work. Both these gentlemen offered to assist, but their health doesnt allow...What am I gonna do after these mechanics by neccessity are gone? These men have a lot of experience using low tech tools in less than desirable conditions. These guys are national treasures as far as Im concerned...Trev.

I havent done this before so the answer is, I dont know. It is quite possible I cant change the cam bearings without taking the engine out. If I cant Ill change the rod and mains, replace with a used cam, and carry on from there. I was gonna use this tractor to seed 40 acres in the next couple of weeks when the weather dries up here,thats not going to happen now so Im bummed. I bought a three bottom Quick Hitch Allis plow to break the ground, but I guess Ill have to disc and cultivate to get it ready to seed... Ill borrow  a tractor to do what I need to do and after seeding get the WD in my garage and get the engine sorted out. Trev.

Thanks Steve. Gonna give it try any how, I was talking to some of my hotrodder/track buddies today at an engine shop and they have done the same method. Said to use same size as pushrods and give the dowel a "tap" to seat it in the lifter and then carefully pull up and clap. We shall see in a couple of weeks...It was a thrill to get the tractor running, did a comp test after it was warm and got 100psi across so thats o.k. I guess. Oh well, it will be a lot better when Im done, Trev.

Thanks Steve for the advice. Is a 45 cam the same as a WD? I think I found a cam for a WD but I would like to know if the 45 cam is the same, opens up some options. Thanks again. Trev.

Thanks for the advice Jim, I appreciate it, we shall see. Im still upset so once the smoke clears outta my brain Ill hatch a reasonable plan...Trev.
