Shift knob threads

Recommended Posts

KrazeyOlDave

EDIT: OMG.... major rookie mistake :unsure: I measured the I.D. of my ball knob and of course it’ll read 5/16...it’s a 5/16 drill size for 3/8 threads :angry-banghead:
 

 

Hey fellas and gals, I went to purchase some ball knobs for a production job I’m doing and I’m getting mixed information. My 310-8 has 5/16-18 threads on the main shifter...my question is, does this vary from model to model?

 I honestly would have thought they would have been 3/8-16. If y’all wouldn’t mind, can ya confirm your tractor model and ball shifter thread size please?

See above Dave edit. 

I. R. Idjitt too. 

 

All the models we've seen here range from early 60s to mid 80s. I don't recall ever seeing a different thread size.  

 

I also don't recall lots and lots of other things!

😂

 

 

@OldWorkHorse Steve has swapped shifters around. He could comment.

Thank you! I’m in process of doing some neat stuff. Here’s a little sample...still fine tuning.0EF3C7BA-914E-4A9A-ADF8-BE1A1601FFD5.jpeg.e0834c5c65209cecd6505aad4d85f342.jpeg

That's a good question, since the tranny didn't change much over the years you would think the thread on the knob wouldn't have either but the one I ordered and installed screwed on with a 3/8-16 thread.

I made a “stupid”.... see my edit of original post. I guess I better layoff the peanut butter and jelly sandwich’s, it’s making my brain mushy 😂😂
