Shifter fork poppet ball and spring

Postby Old Man » Tue Oct 12, 2021 3:24 pm

Had trouble shifting my ‘50 Cub. Removed the shifter cover to discover the 2/3 gear fork shaft had slid out of the front of the tranny case. Found a spring (see pics) but no ball. There is evidence that someone had previously been in the transmission. Does the spring appear to be the right size? What size ball is necessary?

Hi,
Below is a picture from TM Tractor of the ball and spring.

They also have the new ball and spring, it says the size of the ball in the listing. :)

I’m having trouble understanding how the shift rail could move rearward, with a shift fork attached to it. Can you elaborate?

Does this mean you could see the shaft sticking out the front of the transmission housing?

It slid to the rear, out of the hole in the front of the case. The shaft can’t physically go very far forward.
