Transmission Case Crack, need advice

[bob in CT]

The photo on this one looks like it has an expansion plug in the PTO lever hole. It is had to tell on the other one, but there is something dark in the same area. http://www.ebay.com/itm/Cub-Cadet-122-102-Tractor-Transaxle/191679724185?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20131003132420%26meid%3D1c792d2d79d442a484eceaafc4658f5d%26pid%3D100005%26rk%3D1%26rkt%3D6%26sd%3D111717770578

A trans from a Cub Cadet original (1961-1963) will have the PTO lever hole and the threaded holes for the seat mount.

Hi,
The yellow transmissions look good Bob, newer than mine has too. But besides the 3 threaded holes on top not there, there is no oil filler plug or oil level plug where a regular Cub needs them to be. They could be put in though.

I think my other sister and her alien husband would likely have a hard time getting her car through a couple of customs crossings.... Although my sister may find she likes the big city, it would be too far away from her grand kids.

As you know, gotta be careful with Cadet trannys, pretty sure it's rare that it would have everything you need to fit a Cub. PTO lever, deluxe seat bolts, etc.

Also, the rear end (differential) will likely require a change of shims. Read the service manual.

I have a 102 CC with PTO shaft and PTO shift lever. Don't know if the transmission case has been drilled/tapped for the deluxe seat.

I picked up a parts tractor (another 1948 Cub) with a complete rolling chassis last night. I'll pull that transmission apart tonight and see what I bought. Thanks again all for the advice.

If you need a new input bearing and your shaft is pitted, here is a nice fix for that. The driveshaft needs to be turned down to .787 but the bearing is a lot cheaper.

The shaft is induction hardened and the shaft is the inner race for that roller bearing. It the bearing is shot, more that likely the drive shaft is too. There is a fix. You can use a 6004-2RS sealed bearing that has the same OD and a smaller ID. If you can grind that shaft a few thou to match the bearing, it will save you buying a replacement. Mine was able to be turned with a carbide tool. Surface finish is not critical because the bearing no longer needs to run directly on the shaft.

The bearing changed in 1954 at serial 180614 to a smaller needle bearing, so this fix only works on the early tractors.

Here is an old thread that discusses both transmissions. http://farmallcub.com/phpBB2/viewtopic.php?f=1&t=27341&p=213017&hilit=Transmission+input+shaft+bearing#p213017
