R.O.C.K Restoration Project

Tst also makes a decal overlay that restores all the printing and background except the SN and rpm speed. It wouldn't be as pretty as a new one, but an option.

I agree with Bob, Those overlay decals (by TST) look great! So simple to apply the decal.
Much easier than removing the SN plate you have and replacing it with a new one.

Hi,
Below is the first style of Cub serial number plate at TM Tractor. They say it was used until 1950. You can look carefully at the stamped numbers on yours, and see where they would fit on the plate.
It looks like it is the first style of plate.
Yours says F CUB for the model.
The next style of plate has the numbers in different positions.

We had a 1949 Cub here that was newer some than yours, and it had the first style of plate.

Below is the next style of plate. :)

Thank you all for the information...looks like Rocky was manufactured in mid 1949 and according to Raymond's database, there is a Cub with a later serial number sporting the McCormick - Deering Decal. That's good.

Just ordered one of these http://www.tmtractor.com/new/sp/101fp.htm

I also learned that ROCK is handling the emblem/logo. They want to attach it to the tractor permanently, so I'm thinking radiator grill sides.
 
Back to the fun stuff!

I noticed faint signs of oil sling-age stains on the fan blades, indicating a leak somewhere. I followed the manuals directions for filling, then draining the oil and afterwards, noticed this,

so, apart she came,

Cleaned everything with solvent,

and measured the bushing,

The gaskets looked good and intact, any ideas why she is leaking? Is the bushing worn out?
 
As you've no doubt discovered, there is no oil seal on the fan shaft. The system relies on the internal standpipe and centrifugal force to keep the oil in. A little leakage immediately after filling is normal, especially with the fan not installed.
 
In following the service manual, I plan to reassemble the fan this way,

Question; Does the small gasket, laying on the manual, belong with this fan?
 
Tim, in one of the pictures the oil impeller is printed backwards. I’m not sure which is right, do some research or send Jim Becker a PM and ask him. Hate for you to have to redo it.
 
That link sums it up pretty good!

So, this is how I will reassemble the "centrifugal pump", looking from the front of the tractor,

If this is not correct, please let me know.

Question; Is the washer for the oil level screw an O ring?

Looks like you have it right. Backwards 6.

Smart design... If we had not replaced the bolster with a new one, this is definitely an option we would consider. The original plate, however, is still on the original bolster. I had planned to remove it and give it to the new owner. One of the few "procrastinated" projects still left to do.
 
Now for that procrastinated PTO cover install. I have yet to install since Glen pointed out earlier in this thread, two of the bolt holes have some thread erosion. Top left and mid right. Here is what they look like after chasing with a tap,

I planned on inserting coils, but after cleaning and procrastinating, some more, want to know what y'all think? Extra thread sealant? Insert a coil?
 
I would think as long as you use the correct length bolt (to use as many threads as possible), that would be enough. You shouldn't need any sealant, since none of those bolt holes goes through into the fluid area. Gasket does it all.
 
I would go ahead and use a thread lock sealer just to insure you're locked in on allthe threads that are there and filling any gaps where the threads might be worn. MTC
 
Hi,
In the TC-37F Cub parts manual, a 353936R2 is a Gasket Distributor, it goes between the distributor and the base. You can look in the manual, it shows where it goes in the pic.
The manual I have does not have the R3 gasket. You could call your Case IH dealer and ask if that number gasket goes on the distributor.

The parts manual says the seal for the fan hub oil screw is a 27948R1 Ring, 1/4 Rectangular Seal. There may be a newer part number, call your dealer and ask if you want.

I hope you have not been doing all the work to the Cub without a parts manual.
Below is the Cub parts manual. :)

The distributor gasket inadvertently found its way into my fan gasket envelope, making a total of three. According to the manuals, there is only two, which caused confusion on my part.

I have been using the GSS-1411 service manual and the CaseIH online parts store, mainly. Just recently discovered the TC 37 manual.
 
After allowing the paint to dry for 48 hours,

the fan was re-assembled with a backward 6 impeller, or whatever it is called, and a very light coat of aviation sealant on the front gasket.

Ready to be installed.
