Transmission gets stuck in two gears when driving it

[Scott from ontario 3]

Would I just need the new updated shifter rails or do I need the pin that is posted in the picture was also wondering if the ball on the end of the shifter would make a difference if it was worn down?

My grandfather welded the diff casing and the drive gear is worn out on the end I posted some pictures of it and a picture of the shift rails

Thank you everyone who has been helping me out with the wheel horse transmission I posted pictures of it not sure it that one gear has to be changed also

In response to your PM last night Scott.

I can't really see the condition of the inner teeth on your 3523 gear. Here's a NOS and a somewhat worn gear.

 

 

You could make a 3/4" stop pin if you had to. Just get it precise.

 

Another thing you need to do during assembly. Put it in 3rd gear and just let the stops hold it there. Check the input pulley for any in/out play. There should be zero. If there is any it means the 3523 is separating that much from the input gear. If there is figure how much and shim behind the gear before you insert it in the case. It's a pain because you have to assemble things then undo them only to reassemble again but it's worth it.

Ok thank you do both the new rails need a 3/4 stop pin any chance you have a picture of it with the new stop pin in it I’m not sure at all where it would go. Thank you

They are in post #3. They go in from the front of the case. See parts #33, 34, 35. With the 2nd/3rd rail in place (the rear most rail) you insert a 1/4" ball, then the stop pin with the spring, then another 1/4" ball. Be careful as the balls can drop into where the 1st/reverse rail goes. Now the tricky part. Hold the  assembly (2 balls, spring and pin) compressed as you slide the other rail in place. The 1/4" balls are at the hardware store . Simple as that. 🙂

Would you know the length of the 3/4 stop pins they are not available anywhere I was thinking of getting a piece of 3/4 round bar and cutting them to length 

[Racinbob 11,048]

The pins are 3/4" long. The diameter is, I believe 1/8" but I'd have to verify that. I can do that tomorrow. 

Anybody here have an extra 3/4" pin they can part with?

[Scott from ontario 3]

Don’t I need two of the pins? And people on here sell parts also ? 

[Racinbob 11,048]

Just one pin as per the drawing I posted. Yes, there are several vendors here as well as individuals selling stuff.

[Scott from ontario 3]

Ok thank you if you can find out that would be great 

[stevasaurus 22,713]

Cut a stainless steel #6 finishing nail to the 3/4" length.  That will work for you.  Make sure you have good blunt ends on the stop.  

[Scott from ontario 3]

So the length Of the new stop pin for the new  rails is 3/4 would it be the same diameter round as what is in there now just longer correct? 

[Racinbob 11,048]

Go back and read the service bulletin I posted. The #6 finishing nail that Steve mentioned will work. He knows these transmissions. So once again. Get a #6 stainless finishing nail, cut it precisely to 3/4" and use it.

The parts 33-34-35 are not even in the transmission I just looked and I can’t find the spring on line any help with the type of spring that is in there is really appreciated. Also I don’t see how it would stay in there without falling out. 

[stevasaurus 22,713]

The spring, stop and detent balls go between the 2 rails.  The rails hold those parts in place.

[Scott from ontario 3]

Ok when I looked in the hole from the outside I don’t see anything so I guess if I take the rails out that’s when they will come out so it won’t be easy putting the parts in and the rails then ? 

[stevasaurus 22,713]

Check out this video...shows how this goes together.  If your rails are stilll in place, the detent balls, spring and stop are still in there.

While this is not your trans, the process is the same as yours.

[Scott from ontario 3]

I don’t have the spring and balls in between the shift rails I was told the size of balls I need and what to use for the bar # 6 finishing nail but the spring I can’t find anywhere and info on it also can anyone help me out with info on the spring for it please and thank you everyone who has been helping me out with this transmission

Does this look correct for the spring for the 953 trans ?
