Hi all First time posting here I have looked back in the post but would like some opinion. I have been wanting to get into tractor pulling and was thinking of buying a 4020 or something like that from another puller but i remebered my grandpa has an 0ld WD45 sitting out in the barn lot. The tractor has been sitting out for about 5 years (exhust covered with a can) he parked it because it had a burnt piston. Ibvious things i see that it needs from a lookover is plugs, wires, cap. pulled the dipstick and oil looks suprisingly well. Anyways what is the recomendation of the group of how to rebuild the engine to perform the best. However there is a catch. I am a poor college student so this will be a shoe string ( alittle kids one at that) budget. Where are the best palces to get ahold of parts such as rebuild kits, pistons etc. this site seemed like it may be a package deal but a tad on the high side. Thanks FOr the info Travis

A 45 has a lot of power stock, I would keep it close to stock or stock. They were a hot-rod of a tractor just the way AC made them. You could up the compression by putting in D-17 pistons or something like that but I would limit it to that sort of stuff especially if you are short of $.

The fellows on this site are chock full of information! They'll help ya along with pricing stuff and direct you to a good buy. I can help ya with any electrical or tune-up parts along with some of the smaller parts. That WD would probably make an excellent puller tractor. I know some of the guys on this site talk about their WD's and the power they make. Also, you can get quite a bit of info on the Allis site too. You might be able to get away with installing just one piston and sleeve if yer' on a budget, and that's what your grandfather said was the problem. Good Luck! Steve B.

I got some parts email me wut u need. And do urself a favor and go to ebay.com and get a parts manual which also illustrates everything! Trust me it is worth it. I am also a college stduent and for every tractor I buy (with wut little budget i have ) I get a parts manual. It gives u the numbers and correct naems for the parts if u have to buy new and also shows u pictures of everything and how it goes together!

If you end up needing a cam during your engine repair, get one for a 170. It will give a little more giddy up. I don't remember for sure, but I think there might be 2 different p/n's for a 170 cam. The only difference is the cam gear. But I'm not sure. A good parts guy should be able to tell you, or maybe one of these other guys can. I pull a WD and I know it made a pretty good difference in power on it.

Today's Featured Article - Product Review: Lead Substitutes - by Mike Schordine. Lead was oriinally added to gasoline as an upper cylinder lubricant. It lubes the valves and seats. If you rebuild the motor, you could use hardened seats and valves, and unleaded fuel. But if your old tractor runs good, a simple lead substitute added to the gas is a perfectly reasonable solution. And, if you are like me, your tractor is under cover, but it sits outside. So with every temperature change, the humidity in the air collects in the fuel tank, in the form of water. ...
