Poor Man's Restoration

Postby rockfarmer » Fri May 04, 2018 1:07 pm

It's official, the last purchase, and my favorite, has landed me here :dog:

Oh well, it was worth it 8)

Meaning, there is NO budget for a Circle Cub restoration...for now. So, I plan to "freshen up" the tractor by fixing the squeaks first. Those being; (1) the clutch and noisy transmission/PTO bearings and (2) leaking finals. The motor seems to run OK with good compression in all cylinders. The only time it smokes is when the throttle is opened up quickly. One puff of grayish white smoke and it clears right up. The governor surges when the throttle is opened up to high idle. Oil pressure is on the high end of the gauge at high idle and just above the red at low idle. Can't tell if the front and rear seals are leaking yet. Drained the transmission and oil fluids so far. Oil looked clean. Finals are a different story.

Left final was replaced at some point,

Looks like the differential seal was replaced at some point with a few acorn hulls,

The right side differential oil seal appears to be an original,
Right side had one of these infamous findings,

Removed and replaced the upper oil seal,

along with the seat post treasure,

Now how do you suppose all those washers found there way in there? Must have been 20 of them, some very large.

The last one I got had similar treasure that remained in place long after the bulk of the tool box rusted away.

Your discription sounds like you're running my '48 "work horse". Been that way for years, runs like a top.
Unlike Rocky, take your time, just do a little when you can.
My motto, if it ain't broke don't fix it. If it is broke, do what is neccesary to keep it running.

Good luck
Hutch

Hi,
In your 3rd pic, be sure that there is a dowel pin in the lower hole in the transmission case, the top dowel pin is there, but not the bottom dowel pin.
It might be stuck in the hole in the final drive. It should be tight in the hole in the trans case. Pull it out of the final drive hole, if it is there, and hammer it in the trans hole, facing the right direction.
If it is too tight to get out of the final drive, you could leave it there and use it that way.

If there is no dowel pin, you should find one and put in.

Below is a pic from TM Tractor showing both dowel pins in the trans case. :)

The tool box is not sealed on the bottom, probably using the Cub over the years, small parts put in the tool box work their way out the hole in the bottom of it, and get under the tool box, where the seat post bolts are.

Below is a pic from TM Tractor showing the hole. :)

I forgot about the hole in the toolbox. Makes sense, stuff bouncing around until it hits the spot. Any ideas why the toolbox was designed with that slit?

Regarding the differential/final dowel, just happened to have one of those on the shelf Glen,
47 New Dowel diff.jpg


Thank you for pointing that out.

On the left final, there does not seem to be a Part #, just a date of manufacture which is 02.17.R

Question, can I use the R2 final pictured on the right to replace?

The rear finals should be interchangeable IF they both had the same style of brakes. The openings for the toggle and non-toggle brakes are different. I can't tell from your bottom picture as the angle is different on the two finals.

cleaned up the "orphaned-final" found on the left side and there's no casting part #.

47 step final.jpg

It has the large "toggle" brake opening that does not match the right side, R1 final.

The R2 I want to use on the left side has the small "non-toggle" brake openings that match the R1...did not know if there were any other differences.

Quick update;

Already blew the budget by $22.00 after pulling the transmission apart. Both o rings and seals in the retainers need replacing and maybe a shim or two.

47 Retainers.jpg

The upper retainer was removed from the right side. The bottom retainer came from the left side and has a newer style oil seal. The left side had the final with without a R part #.

Could not for the life of me get the pinion gear out without first removing the bearings.
47 Diff Bearing removal.jpg

I know the bearings will have to go on before re-installing and hope someone confirms that it will go back in with them on.

All the transmission and differential bearings are worn and gritty feeling so they will be replaced, including the races, all of which I have in stock!

The gears look to be in pretty good shape and will not need replacing, I hope! I will let you all be the judge on that.

I have removed the castle nut from the input shaft but cannot remove the shaft. I know it comes out from the rear.
47 Diff case.jpg

Question; How is it removed again?

Edit; I am referring to the countershaft, or bottom, not input shaft.

This bearing needs to be removed in order to remove the countershaft and is on really tight.

I can't get a bearing puller behind it. Any ideas?

Cut off the outer race, score the inner race and hit it. Races are brittle and it should shatter.
