Tranny whine & jumping out of gear

Postby Super A » Sat Oct 17, 2015 7:35 pm

IH Collectors chapter 37 hosted its fall plow day today at Greenville, NC. It was a great day, and was almost an all-Cub day, save two 140s and a W6. I have known for a long time that the transmission on The Paperweight was showing a lot of wear, plus the case has been "busted and welded" on the bottom, but today I noticed it was howling louder in 2nd gear, and in a bit it started jumping out of gear. Guess I'll pull the top cover off and take a look, but I am mighty tempted to swap out the whole thing. Thoughts?

Is it a family heirloom? No, then swap it out!

:Dito:
Unless grandpa broke it trying to pull grandma out of the ditch in her new Packard, it goes. Even then I think it would be a better door stop (painted up nice) than transmission case from your description. I guess you should take a look to confirm it's not something simple though. Would hate to find a loose bolt, etc. after you've bought all the new parts and then tore into it.

There's no sentimental attachment whatsoever! I have seen folks talk about swapping for a Cub Cadet transmission over the years. Other than flipping the differential, what's involved there?

Thanks

Make sure you get one drilled for the rockshaft and PTO shifter. I posted some links to eBay a couple of months ago and people saw that the later cases were not drilled the same as Cubs. There should be a expansion plug that can be knocked out in the PTO shifter hole, though. Like Ed said, the driveshaft needs to be changed, so there will be some swapping to do after you make the split.
I never used a case. I swapped gear sets as I wanted to keep the original casting date. Seems to me that the lower pinion shaft bearing cover is different, too. One nice thing about the older cases is that you can use the sealed bearing upgrade if your transmission shaft is worn and pitted. The bearings ride directly on the shaft. In the newer cases, they use a needle bearing instead of the larger diameter roller bearing so the seal bearing is not an option. The original bearing had a hole in the case that was installed in alignment with an oil passage to feed oil to the bearing. The Torrington factory that made those is closed and none of the current suppliers have the bearing with the lube feed hole in their catalog. Probably won't make much difference for our use but I much prefer the sealed bearing fix as it saves the expense of a new driveshaft. I have not see one yet that I was excited about re-using.

I see that second gear in the CC tranny is one tooth different. Will it be faster or slower in the farmall cub?

Working from memory and doing math in public can be dangerous for me. The older cubs had a 17/35 second gear setup and the newer ones a 16/36 setup. The CC Original has a 16/36 second gear setup, which should be slower than the 17/35 setup.

Hi,
Like Bob said, people on here were talking about this not long ago. I noticed in the pics of CC transmissions then, that they had no trans oil fill, or level plugs like a Cub uses. Don't know if there was a drain plug like a Cub has, they didn't have pics of the bottom.
I have had Cubs with the newer and older second gear number of teeth, and I don't notice any difference in the speed. It is a slight difference evidently. :)
