Shifter rod removal

Postby jastusa » Sat Feb 05, 2022 12:29 am

Hey team,

I’m replacing a gear as there’s a broken cog; tractor separated etc, trying to remove the shifter rods, which are turning so don’t appear to be stuck, and are freely moving. I’ve got the manual and watched a YouTube clip; apparently they should slide out towards the front of the cub.
However, in the case where they should come out, mine has caps inserted in there, see photo, and those things are not budging. Are they meant to be there, and how do remove? I’m using vice grips to slide the shifter rods, but can’t get past the caps..hmm. Any help would be appreciated. Cheers, Jason

Those are Welch plugs. They can be removed, but not reused. TM Tractors has new ones:

I see, thanks Dale. Got them out, this is turning into a disaster, the bearings have all fallen apart, two broken gears, water in there also, so I’m going to do a full transmission tear down.. more parts being shipped to Australia .. thanks though. Cheers, Jason

You didn't say the year of the Cub.

IH changed the numbers of teeth on the 2nd speed gears, on the USA Cubs, at Cub serial number 192113, which was made in later 1955.
The Cub parts manual shows it, the 2nd speed gears are numbers 8, and 22 in the pic.
Notice in the description below the pic there are 2 listings for those gears. ... 007-08.jpg ... 007-09.jpg

IH also changed the rear bearing in the housing, for the upper shaft, to a needle bearing at Cub serial number 180614. The needle bearing is a smaller OD than the older roller bearing, so the hole in the housing is a different size than the older bearing.
It is shown in the manual also.

Look closely so you buy the right parts.

The ball bearing on the upper shaft probably needs to be pressed off and on the shaft. :)
