1958 farmall cub trasmission

Postby Cubbuilder » Sun Oct 17, 2021 7:16 pm

Hello cub experts, Im rebuilding the transmission on my early 1958 cub. There was a thread on the rear input shaft bearing. Mine has the smaller caged needle bearing O.D. 1.125. The question was not really answered about the oil hole or weep hole on the bearing case. The one I bought does not have this hole. Do I drill one in which presents a host of problems or leave it and install as is? I cannot find a replacement sealed bearing for this size. Any thoughts...

My opinion, just install it as is. Many times the oil feed holes are plugged with dirt anyway. There will be enough splash lubricant from driving. If your transmission was noisy, consider the bushing in the reverse idler. Have found these get worn and become noisy. New ones are available and will need to be carefully honed .002” clearance. Good luck.

Hi,
Welcome to the website.
I would rather have the oil hole, so the bearing gets oil from the transmission oil trough.

You could ask about the bearing at a Case IH dealer, and see what they sell, if you didn't.

Below is a listing for the bearing at TM Tractor, which is at the bottom of the page, it says it is a Case IH bearing, but it doesn't show there is an oil hole in the pics. You can look at the pics.

If there aren't any bearings with the oil hole, I guess you will need to use a bearing without an oil hole. :)

I had the same issue, called the parts suppler and they did not know, but said if I drilled it and had a problem they would replace it.
I ended up using a cutting wheel because the bearing is very hard. It is working so far. I prefer that it is getting oil.

Thank you all for the input. I did buy the bearing from case IH and it came without the hole. They had no opinion on the matter. A mechanic overheard the conversation and said he would add a hole. I have mixed emotions on the issue. Would take a great deal of work to replace later on with a failure, I use the tractor for organic farming. The hole on the original is quite small so I agree with Steve tractor that the hole would likely plug down the road. Not sure how to drill a hole without debris or damaging the bearing. Bearing wasn't that expensive so time for experimentation. Thanks again gentleman.

I could not say tractor when I was 2 years old so I called it Err Err.

I loved this tractor then and I still love it now.

Insert a little grease in the bearing behind the area you are planning to grind.
Cover the bearing sides with tape to keep debris out of the bearing.
Use a Dremel or similar tool with a diamond tipped grinding attachment.

Clean thoroughly with brake clean or carb cleaner to remove the grease and all particulate matter caught in the grease. Dry the bearing out and lubricate with a heavy oil prior to installation.
