Awesome job so far. Cool little project. If I read correctly on the article you linked it has a type of turning brake set up. Beyond it's time.

Are those a solid rubber tire up front?

Oddly though there are no brakes at all on this tractor. When you turn tight the final drive belt for the inside wheel is loosened so that it will slip. Kind of a strange differential.

The one front tire that was on it when I brought it home was hard rubber. It is supposed to have pneumatic tires on the front. 4.00 x 8's

I mentioned that the steering wheel that was on this tractor when I got it was wrong. Today I had a little time to work on things so I made a new steering wheel. 58aa411cd4936_chassis21.thumb.jpg.da718aa66f6b10f35e28af56fe068a72.jpg

 I also wanted to share some of my progress on the transmission. The tranny is one of my biggest challenges on this tractor. There are not many parts that can be purchased for this thing so you will notice that most of the parts are going to be made or altered by me. The first rack that I started on was the input shaft. I had to cut the shaft on both ends to remove it from the tranny. The o.d. required to make the replacement pieces is 1 3/8". After some searching I found that this was a special order size and it was actually more expensive than 1 1/2 at the places I checked. Then when I was removing the axles from my wood hauling trailer (which was a 1 ton GM truck originally) I noticed that they were 1 3/8" o.d. Score!!! :greetings-clappingyellow:It didn't take long for me to figure out exactly how difficult this material was to work with though.:mellow: I learned that it didn't like to be rubbed, things went much better if you were more aggressive with it. Other wise it wanted to work harden on you. After figuring that out, things went slightly better. The rack of gears at the top of the pic is what I have to replace. Below that is the start of my new pieces. The three smaller pieces will need sprockets welded on to them and will need bushings inserted into the bore of them. The two longer pieces need some time on the mill yet and will need an internal key way cut into them.

A progress report form this weekend. I'm waiting for some tranny parts so did some chassis work this week end. Below is a pic of the ugly hood hinges that a PO made. At least I have to believe that these were home made, I'd like to think that these are not factory.

58b36a16e7a28_Body5.thumb.jpg.ce3158a12adc1114c294ff2f748848e5.jpg

My new hinges have a little more style. In order to use the existing holes I had to make one a stud on each of my new pieces. I did this by drilling and tapping a hole in my new plate. Then I threaded a bolt in to the hole, cut the head off of it and welded it in place. The two remaining holes i decided to tap so I would not require a nut on the inside. While doing this I busted off a 1/4 x 20 tap.:-o I got lucky and was able to remove it by catching one edge with a chisel and tapped it around with a hammer. For any one that has broke off a tap, this was a victory all it's own. :greetings-clappingyellow:Here's the icing. I didn't have another tap so I ground the end of the broken tap flat and was able to finish tapping the hole with it. :handgestures-thumbupright: Skill / dumb luck? Either way I was extremely happy. Any way a pic of my new hinges.

58b36f9568a28_Body10.thumb.jpg.fd7679e9381f0d09c8f3bc9b3207ce22.jpg

Also took some scrap 1/2" round stock and turned a couple hinge pins. I know the clips are at different locations, I had to do that to compensate for reinforcing the engine mount plate.

58b36f9ee4526_Body15.thumb.jpg.e60b43fe2b0119ec818828a9f1d780aa.jpg

I also removed all of the unwanted/wrong items from the rear end. I'm not sure they ever made it work but a PO had replaced the original rear axle with a live axle set up, so pretty much every thing had to go. A pic of what I started with.

58b3717b23c83_chassis1.thumb.jpg.c559b90a88fe9f199aefa8333aa550bd.jpg

After a lot of cutting and grinding, I got every thing stripped off except for one shaft. That will have to go too.

58b37401123b4_chassis2.thumb.jpg.8d59d254f6c9d1216998393144d45e3a.jpg

I removed the last shaft and cross bar that was not supposed to be there. A PO had also cut some metal away, so this had to be replaced.

58b3739a50fa9_chassis7.thumb.jpg.447738b30e5925d590d9ae2bc4e09284.jpg

The chain had wore into a reinforcement plate for a bearing towards the top of the chassis. Also there was damage to the axle hole from when some one removed the original axle.

58b3738658473_chassis4.thumb.JPG.35565a7aed8be81eebb7d711ac5e2585.JPG

The bearing plate was my biggest concern, I had to be able to press a  1 3/8" o.d. bearing into this hole. After a couple mistakes, I got it right and had a good fit. Then I made some plates to repair the axle holes.58b373909ed9b_chassis5.thumb.JPG.857c55e62a57343adac68da40feafed3.JPG

Hope to post more progress next week.

@achto, you got skills sir!

 

nice work. It's becoming apparent with each update post you make that I need a lathe and want a mill.

 

im enjoying this project albeit vicariously!

Thanks @Aldon  I was lucky enough to have a great metal shop teacher in high school,(30yrs ago:wacko:). He peaked my interest in working with metal. We had an awesome shop with mills, lathes, surface grinder, fab equipment, welding equipment and a foundry.We even had an small CNC mill. Our senior year we had two class periods per day for one semester to make any thing of our choice. Some of the stuff I made is still in use today, Cherry picker hoist, car engine stand, torpedo level, just to name a few. Unfortunately now, many industrial arts classes have left our schools.

Sad but true, I had power mechanics 1&2, Machine shop 1&2, woods & metal 1&2, Auto mech. 1&2, trade math where you learned how to read mics & calipers & such, All very interesting stuff & laid a great foundation  for a 16/17 year old kid who might turn out to be a "gearhead". Just don't see that in todays schools, maybe that's why CNC operators, welders, machinists etc.  are in high demand today!

Same here! I might have to take some pics of stuff we were required to make and I still use to this day! Lead hammers, centerpunches, vises, I ever get a buddy of mine to sell me that vertical mill (he doesn't use) we are gonna have fun!:)

Thank you for the complements Jim & Richie. Finishing the transmission was a major stepping stone towards finishing this project. I still have a long row to hoe on this restoration though.

Thank you Jim W. & Richard.

 

I want to send a big thank you to @Vinylguy for his part in this restoration. I sent him this very poor pic that I found on the net.

He put his skills to work and was able to make me these beautiful decals.

I think he did a fantastic job on them.:handgestures-thumbupright: I can't wait until I'm ready to install them.

Hi, I'm back again with another update. This weekend was dedicated to building my rim / hub assemblies. I purchased some 1 1/2" o.d. tube with what I was told was .125" wall. Make life simple, install 1 1/4" x 1" bushings and job done. Right? Wrong! The tube actually had .120" wall, when I put 1 1/4" o.d. bushings in it was like throwing a hot dog down a hall way.:angry-steamingears: OK, option 1. Turn down some 1 5/16" o.d. bushings to 1.26" o.d. 2. Bore the tube out to 1 5/16" i.d. to fit the larger o.d. bushing. I choose option 2 for these reasons, keep the bushing a standard size for ease of replacement and this would give a positive stop inside the tube so that the bushing could not work its way out of place. So... back to the lathe.

58c57c736cb01_wheel20.thumb.jpg.944467f1c788b5590b9ba17c10550c3e.jpg

58c57c7c6297a_wheel25.thumb.jpg.32b46ed7893f310737234dde6df88ab9.jpg

Next was to clean up the original rims. A PO had messed the centers up pretty bad .

58c57d3d7305e_wheel10.thumb.jpg.ad9a818b114f6bfd390bcbbea182ec61.jpg

After a little bit of cutting and a lot o bit of grinding the rim was back to ground "0".

58c57d45e08ab_wheel15.thumb.jpg.f71c825cec853b7468ae6d98f49c12f7.jpg

I used the hub for the sprocket as a stop to hold my new rim center square on to the tube.  I positioned the hub at the correct distance and snugged up the set screws. This worked great, it gave me a way to hold the center for welding.58c57e8fee71e_wheel35.thumb.jpg.2df2f7159d4f1e4b1f4fe3e8e386459f.jpg

Next adventure was to get my new piece centered into the rim. After a few different trials and errors I came up with the easiest way I could think of. I turned down part of some 1" stock to 1/2" so that it could be put it into a drill chuck on the lathe. After centering the rim in the lathe chuck I put the shaft into the drill chuck and slid the new tube & center onto the shaft. Then tacked the center to the rim.

58c57e9986e4d_wheel40.thumb.jpg.3b33e2faa24bcb44344f05f59245f692.jpg

With the rim / hub built this far I could now cut my axle to length and drill & tap the ends to 1/2" 20 thread. I cut the axle length to leave .01" end play after every thing is tightened down. Then welded the axle to the chassis.58c57e87271c5_chassis45.thumb.jpg.403c5ddc826d5fe7aee27fc96c6de50d.jpg

Welded the sprockets on to the hubs. Then positioned the sprocket to leave clearance so the chain will not rub on the chassis and welded the sprocket hub to the tube. Rim / hub assembly complete.

58c57ea251d77_wheel45.thumb.jpg.0da3411c3fb13642c17fdf8d12c6e085.jpg

My goal for the wobble & hop on the rim was .05", after welding things moved a lil. :doh:I ended up at .123" on the wobble and .074" on the hop. At a projected 4.5 mph in high gear, wide open throttle I think this will be livable. :)

58c57eab3c25b_wheel50.thumb.jpg.28afbe2aa497e3096f7932cb4449330c.jpg

At this point I think I'm ready to sand blast the chassis and get some Red paint laid down on this project. I need to paint before I can  move on to making the differential pieces.

If any one wishes do give their opinion. I'm trying to decide if I should leave the inside of the transmission bare, paint it with the same acrylic enamel that I'm using on the rest of the tractor, or paint it with Glyptal paint. The inside of the trans will have 80/90w oil in it.

Glyptal paint and coatings is expensive stuff, is there any advantage to using this as opposed to acrylic enamel, for the inside of the trans?

Glyptal paint is made to be used inside engines, plus it is supposed to seal up any fine pores. I was thinking that it might be better in an oil bath situation than the acrylic enamel would be. :confusion-shrug:
