I have shared this project on two other forums I frequent and I thought you guys would like to see it also.

 

When I was a young boy I had this idea of building a Case GT painted up like the first 94 series Case Ag tractors with the colors of Power White sheet metal, Black frames, and Power Red Wheels.

I also dreamed of big bar tires with wheel weights. I always liked this color scheme and so after I broke the hydraulic cylinder lift mount clean off on my 1984 Case 226 I started taking things apart to fix it and after removing the engine and finding many things needing repair I decided to keep going and start my Resto-mod that I had always dreamed of as a kid.

 

I did several modifications on the tractor to make things stronger. I further welded factory welds, I rebuilt the front axle pivot with sleeve collars welded to the frame plates, and PTFE coated high strength steel bearings pressed in after having the bore machined out with a solid shaft to fit it within .002 of clearance.

I added thickness to the frame where the engine mounts on the frame and where the lift cylinder bracket is installed. I had the lift lever, travel lever, and pto engagement levers chromed. The front tie-rod was made stronger and many other things I'm sure I'm forgetting.

 

The engine was a very low hour Onan I bought several years ago and so I pulled the heads off and decarboned the heads and I did some light porting and polishing on the intake and exhaust. I built a custom muffler with a dual outlet exhaust that still remained under the hood in the factory location. I just had to cut an outlet on the other side of the hood for it. Other performance mods were done to the engine as well.

 

Ok enough writing. If you have questions just ask and I'll try to answer. Here are some pictures.

I'll start with what I started with. A 1984 Case 226.

Your front axle pivot re-work looks like it's twice as strong as the original set up. Should last another 30 years easy. But I would guess it's going to have an easier life from here on out?

Great tractor!   I saw it on another forum, but it is always worth another look.  

 

An easier life now?   I wouldn't bet on that.   I've seen the plowing videos..   :rocker2:

Your front axle pivot re-work looks like it's twice as strong as the original set up. Should last another 30 years easy. But I would guess it's going to have an easier life from here on out?

Yes Thank you. I do plan on using the tractor for plowing/shows. It is still fully capable of using all attachments such as a mower deck and snow blower if I so choose. So it will get worked pretty hard. After I was finished building it I ran it through some very rigorous tests to be sure it would hold up to extreme use. It failed once, but that was quickly fixed and then retested. I also did this testing before tear down to reveal any weaknesses I should fix during the build. That is some of the reason the cylinder mount bracket busted off. A weak point that needed correcting.

 

The front axle will out last the tractor now. The machine shop that bored out the axle recommended a sleeve bearing shown below and the shaft is some high strength steel they gave me. It's a polished solid shaft close to the same size as some big tractors have.

I ordered the bearings and since they were to long to press two in the bore I cut two bearings shorter and pressed in one from each side to allow a small gap for grease (although its unnecessary since they are self lubricating) and the tolerances are to tight for grease to penetrate.

To hold the pin in I drilled a small recess in the shaft for the collar set screw to be tightened into with a dab of Loctite.

 

Purchased through McMaster-Carr:

Polytetrafluoroethylene (PTFE) interesting facts:

 

Extra-Strength Metal-Backed Sleeve Bearings


60695kp1s.png?ver=10309627

A metal shell adds strength to these bearings.

Steel-Backed PTFE-Coated BronzeThese bearings have a steel shell and a bronze lining, which is coated with a thin layer of low-friction PTFE. They resist corrosion and water absorption and are electrically conductive. They also have the highest load capacity of our metal-backed bearings and are well suited for rotary and oscillating motion.

 

The coefficient of friction of plastics is usually measured against polished steel. PTFE's coefficient of friction is 0.05 to 0.10, which is the third-lowest of any known solid material. PTFE's resistance to van der Waals forces means that it is the only known surface to which a Gecko cannot stick.

 

PTFE can be used to prevent insects climbing up surfaces painted with the material.

 

Neither water nor water-containing substances wet PTFE.

 

PTFE has one of the lowest coefficients of friction against any solid.

Here is the broken cylinder mount that was pretty much the deciding factor to tear the complete tractor down and rebuild everything new or better and what I did to rebuild a new one.

I also strengthened the frame in the area the mount is welded to. Looking back I wish I had bolted the mount on, but no going back now. lol
