Transmission Help Please

Postby Command52 » Sun Mar 03, 2019 12:52 pm

I got all my new bearings in so im cleaning parts up and i noticed 2 things, Up by the bearing you will notice that the shaft is buggered up on the inside of the bearing, Is that for a reason , Also when i went to slide the gears on the end of the shaft it will only slide so far Maybe 1/4 inch , If you look at the shaft where the pen point is you will see like a gash on the shaft . Am i doing something wrong Thank You Billy

You will need to file that gash down so the gears slide over the shaft without hanging up. Also, the gears go on, with spacers, while inside the transmission case like this,

you probably already know that.

The retainer that goes over the bearing pictured above looks like this when finished.

Retainer protrusion goes inside the transmission.

This is what i would call the drive shaft , I have the other gear assembly with the spacers all together but are these gears in correct order to go on
this shaft. That bur looks like it was made there.I know i will have to take them back off the shaft to get in the transmission but i cant figure out why it wont go on the shaft as they fell of when i removed the shaft originally and dont under stand the burrs by the bearing

I believe those "burrs" by the bearing are forming a "shoulder", against which the bearing rides.

The upper shaft is made with a stop for the ball bearing to go against. Drive the bearing on until it hits the stop. It looks like the shaft in the TM Tractor pic that Don posted above. I can't see your pic too well, it is sort of dark on my computer.

There should be nothing rough on the spline area of the upper shaft, where the pen is pointing.
File it flat, and file the sides of each spline, if needed, so the gears slide on easily.
The gears should slide easily, up to the front of the splines.

Something made a gash in the spline evidently, I don't know what it was.

Check the PTO pilot bushing before putting the clutch shaft in the transmission housing, much easier to replace it while the shaft is out. Put the end of the PTO shaft into it, and see if it is worn or loose. The small bushing has to be good.

Below is a listing for it at TM Tractor.

Below is a pic from TM Tractor of the rear of the clutch shaft, showing the bushing, and what the PTO spline should look like. :)
