Gear shifter.

Postby lawnmowerman1960 » Wed Nov 18, 2020 6:43 pm

This may be off the wall, but when my 49 Cub is in neutral, to me it seems to move kinda stuff. I makes no difference whether I've ran it or it's cold. Since I've never owned one before, maybe it's normal. It shifts fine, and the driveline is quiet. Advice?

I'm guessing he meant "stiff".

Have you pulled the shifter cover off to try to diagnose the issue?

Stiff would be appropriate. No, I have not pulled it off. I'm hoping, since I've never had one apart, what's involved or special things I need to look out for while taking the top off.

All you need to do is put the gear shifter into NEUTRAL, remove the bolts around the cover, then pull straight up. May need to carefully pry up a bit if the gasket is stuck.

You can't see very far into the transmission, because the gears are in the way, but you should be able to check for chipped or broken teeth. Also make sure the bolts holding the shifter forks are tight and the forks have no cracks.

While you have it open, it is recommended that you make sure the channel that runs around the top edge, is clear of gunk, and the 2 holes, one at the front center and one at the back center, are open. They supply oil to the front and rear bearings.

Make sure you have a new gasket on hand, or if you're not picky, some silicone gasket maker. Gear oil will get flung up and out of the transmission if the cover is not sealed.

And do you mean the shifter is stiff? Or the tractor doesn't roll freely in neutral? If the shifter itself is stiff, you can lube the shift tower with something like PB Blaster and it should free up a bit. The shifter shouldn't flop around and should hold position when you let go of it.

Hi,
If you mean the shifter just moves hard from side to side in neutral, or shifting into gears, it might be dry and binding at the top, outside of the transmission.

Below is a page from the Cub parts manual showing the shifter. The shifter on the left of the page is the one a 1949 Cub would have originally had.
Try prying up part number 5 with a screwdriver, and squirt some lube in under it, from several directions.
Spring number 7, holds 5 down, but it will raise up some.
You may not need to remove the shifter, if that is what is causing the stiffness.

Below is a pic of inside a Cub transmission, with the shifter cover off.
If you need to remove the shifter, put the trans in neutral before removing the shifter, the 2 forks should be aligned, like in the pic, and the ball on the end of the shift lever goes inside the holders on the forks.
The pic is looking from the left side. :)

Thanks for the help. I'll try that. It's probably nothing, but moving the shifter in neutral side to side seems tight. Maybe that's normal, I'm used to old Ford's and their neutral feel. First IH I've owned, but 45 years ago I spent quite a bit of time on an H and it wasn't this tight.

Hi,
The shifter should move sort of easily, but not feel loose, or overly tight. :)
