Transmission shaft

[pickerandsinger]

you can push the bearing on to the shaft only so far, it has a raised part to stop it

....The new one will go no further without force...The old one is up to the spline edge ...Must have been forced...This probably attributes to the problem with the tractor..Dave

Thanks Tim...That piece of the puzzle is solved...Only a couple more to go...Dave....

Sent you a PM not sure if it got through.

Hi,
The ball bearing has to go on the clutch shaft as far as it will, until it hits the raised area made on the shaft. If it is tight, press it on, or drive it on somehow. Apply force only to the part of the bearing next to the shaft, not the outside edge.
Then put the snap ring on the shaft, the bearing should be to the rear of the snap ring groove then.
Maybe you already have it installed.

On mine there is no snap ring on the front transmission bearing. The bearing slides against a shoulder or the enlarged part of splines, don't remeber which, and the seal retainer holds it and the shaft from moving. Note, the retainer goes extending into the transmission, not sticking out.

Here's the picture of ours when I put it back in.

....OK, so when you put the transmission input shaft back in was the bearing mounted on the input shaft or did you seat the bearing in the transmission case and install the shaft splines thru the installed bearing......Dave

I put the bearing on the shaft then put it in the transmission. I had my transmission completely disassembled at the time.

...it is just a round snap ring with no special ends on it so it is hard to see at 1st and be careful removing it not to bend as it is not sold separately

You can probably order one from McMaster-Carr https://www.mcmaster.com/#retaining-rings/=17v41mf

....We're getting there...Now did you put the bearing on from the long end ,open face of the bearing , facing the engine or did you install it from the spline end that goes into the transmission....open face toward engine... I will explain why I ask later...so as not to confuse... Dave

[Slim140]

It should only go on from the long end and open end facing toward engine. The front bearing shouldn't be able to slide over your splines.

........... or did you install it from the spline end that goes into the transmission....open face toward engine... I will explain why I ask later...so as not to confuse... Dave

If you have the correct parts even asking that question is confusing me. I can't wait for the explanation.
Does this have something to do with the rear transmission case bearing on the very rear of the shaft by the PTO splines instead of the front transmission case bearing 3/4 of the way back? They are two different sized bearings and the rear one comes in two versions.

....The short explanation is I think the wrong bearing may have been sent to me...The long explanation is ....Dave....

Hi,
While the clutch shaft is out of the transmission is a good time to replace the rear bearing in the case too. You have to remove the PTO to replace the bearing.
They changed rear bearing styles at Cub serial number 180614.
The newer bearing is a tight fit, and is driven into the case. You have to turn it the right direction so the oil hole made in it aligns with the oil hole in the trans case.

Here are listings for the front bearing, and the 2 styles of rear bearings at TM Tractor, and pages from the Cub parts manual.
Below are pics of the rear bearing in the case.

Dave, the front bearing is a ball bearing and can only be installed from the clutch end of the imput shaft, the rear is a needle type bearing
