'48 C60 engine rebuild

[Gary Dotson]

I would, absolutely, lube the pump gears! In cases where the pump has to lift the oil (c-60) I would pack the pump with Vasoline.

Ok thanks, I will do that. I also made a pressurized oil injector out of a yard sprayer, which I plan to use to pre-charge the oil galleries prior to starting the engine. As it turns out, and I had seen warnings on here, the Reliance Engine Overhaul kit, sourced through my machinist has the wrong oil pump gasket, as it is much too thick. So I am waiting for the correct one to arrive from TM. But I appreciate the advice.

Governor Oil Seal:
I hope to install the new oil seal between the Mag and the governor tomorrow. I have the 'mighty fine tool' created by tst, with a shim for the newer, thinner oil seals. I have misplaced any instructions Tim gave me, but I am trying to determine if the new seal in my Reliance rebuild kit is the thinner seal or the typical seal (for which the tool is designed without the spacer). What is the thickness of the seal that does not require the spacer (or what is the thickness of the one where I should use the spacer)?
Thanks Phill

The last time I installed that seal, I tried to find the information you are looking for and was not successful. So I measured how far the seal I used needed to be set in order to seal correctly without contacting the governor slots. The seal I used was purchased from the IH dealer and is part number 251379R91. It is manufactured by National and is their part number 450313. it is 0.5175" thick. With that particular seal I used the additional shim supplied with the tool, which inserts the seal a little deeper. It has been installed for almost 10 years and has not leaked.

This is some good information. I wonder if it could be saved in the how to section?

[phill_mi]

Thanks for the info. I see that the National 450313 has a specified thickness of 0.500 inches which is close to Bill's measured thickness. On reflection I think in the past I have used the tool without the extra spacer to set a National seal in place. I also noticed that the seal provided in the rebuild-kit is labeled "SA 2.000 3.250 0.435" so it seems that I should use the spacer with this seal to achieve the proper depth.

Fan Hub re-assembly:
As I prepare the engine for painting I am also cleaning up some of the related assemblies, and today I took the fan hub apart. Being a '48 tractor that was very tired and worn out, it has the non-sealed fan hub design. My question relates to a coating that I observe on the inside of the hub around the outer perimeter. It is about a 1/16 thick and is hard but brittle along the edges where I removed the cover. It breaks into a very gritty powder. I think it is old dried oil. I can remove most of it along the open rim of the hub with steel wool but as the space gets smaller due to the cone it is hard to get at the inner portions of the hub. Does this matter?, or should I ignore it. When I took the hub apart I noticed a lot of grittiness on the parts which I have cleaned up. On the other hand the shaft seems to fit without and slop or wobble so I don't thing the grittiness is due to metallic wear. The #6 hub gasket is apparently baked into #7 of this diagram, as I have not been able to separate it yet:
https://www.messicks.com/cas/147340
So I have some more cleaning to do and some gaskets to make when I find some thinner gasket material than the #3007 1/8" thick Cork Rubber that I have. Any suggestions on how thick the gasket material should be for the two gaskets?
I also observe that Messicks has recently changed their web interface to accessing these drawings, and some selections do not show the drawings or seem to show incorrect drawings, such as selecting Cooling and then Fan results in something unrelated to the Cub, it seems. But the correct drawing is under Power.

Hi,
Below are listings at TM Tractor for the fan hub gaskets, maybe you can see the thickness in the pics, but there's no pics from the sides of them.

Today a fellow cuber who is active in the local antique farm power club, dropped by to look at my '48 Cub rebuild project. The engine is still on a stand as I clean up the bolster and other parts and prepare to paint them. But he was interested in the rear tires on my Cub. They are Firestone Champion Ground Grip Track Center "turkey track" tires that he said looked almost new. He said that they are not available any more and that a restorer might be interested in them for more than the cost of a good working pair of tires, since my plan is to put this tractor to work when I get it running. It seems like a lot of work to change the tires, but I was wondering if these tires are that rare and in demand?

I also have a pair of “Turkey Tracks” that look almost new on a ‘48 Cub I bought from an estate sale. I knew the guy that owned it when he was still alive. I bought a lot that day. He was a great guy and showed me everything he had the first time I ever met him. He was 93 then.

believe Miller tire is making them now ?

Those turkey track tires are deceiving, they look like they would offer a nice, smooth ride but it’s just the opposite, they are the roughest riding tire ever.
