Transmission shifting question

[Urbish]

The manual for the 1947 shows the yoke in the upper hole. I believe a nut and bolt are supposed to be through the bottom hole. If the nut and bolt are missing, the two halves of the yoke can spread apart and the throw out bearing can become disengaged from the yoke. This may be part of your issue.

Put it back together as in picture. Clutch rod adjustment was as far as it could go. Checked pressure plate by depressing clutch pedal, all looked OK. Started up with tractor in neutral and clutch depressed, pressure plate was spinning. Is it supposed to be spinning. Noticed in the parts manual that SN 501-32228 was different than 32229-up. What was difference in rods? Is it posible that the wrong rod is in it?

Hi,
The pressure plate is bolted to the flywheel and spins with it. When someone pushes the clutch pedal down with the engine running, if you are looking in through the clutch housing hole, the clutch shaft to the transmission should stop turning, and the thin clutch disc should stop turning, it is attached to the shaft with a spline.
Here is a page from the Cub parts manual showing the clutch parts. The rod on the 1st style linkage has threads and an adjustable yoke on the front end of the rod.
The newer style rod has no adjustment, both ends are solid on the rod.
Here are pics from TM Tractor.

Thank you Glenn, I should have realized that. I will check again tomorrow to see if shaft and disc are turning.

I just realized that I may have been turning the PTO with the PTO lever in the wrong position so I am going to do it again before splitting. Stupid Huh

[Glen]

Hi,
You haven't said lately what you are doing, if you are turning the PTO with a motor, like was said on page 2 of this post, and want to turn the shaft up to the pilot bushing, then you need to have the PTO engaged, the PTO lever to the rear.

Going to turn it with a motor. I had it in neutral and clutch depressed and shaft was turning and pressure plate was still. Pilot bushing.

[rstoots]

Turned it with motor for more than 8 hours, still have shifting problem however I have a new symptom, when I depress the clutch with engine running I get a really loud noise. I assume I have totally damage pilot or something else. Will split and check all components. It will be a while so I will post my results when I get into it.

[Urbish]

Thanks for the update. Let us know what you find. Might want to have a new graphite throwout bearing on hand, soaking in cheap grease, before you split it.

[rstoots]

Is there any way the gear clashing could be a transmission issue? Want to rule all out before splitting.

[Urbish]

The gears should come to a complete stop when you push in the clutch. If they're not spinning, they won't clash. Something is keeping them in motion. It seems that you've narrowed it down to the pilot bushing ID being too small.

[Glen]

Hi,
There could be no damage, it might just be the pilot bushing is dry of grease. Be sure to grease it and the end of the shaft when putting it together, after you ream it out some, if that is what you are going to do.
Here is a page from the Cub service manual showing the size of the end of the clutch shaft, and the running clearance for the bushing. Measure the shaft end, it should be smooth, and then ream the bushing so it is .004 - .006 inch bigger than the shaft, like the page says.

What kind of noise? Grinding, screeching, squealing, clacking, growling?

...... I get a really loud noise. ........

I can't see that question without thinking of poor ole Charlie!
"What kind of noise?" question is at 7:30.

You might need to adjust the free play of the pedal. If it is misadjusted, it can push the TOB hanger assembly too far forward, causing it to hit th finger adjustment nuts. You can look up through the clutch housing hand hole, while pulling down on the clutch pedal to see if it is going further forward than those nuts...with the engine shut down!

Good luck!
