Link from Gearshift to Arm on Transmission

[Fourward]

The shop manual says there is a washer spring, washer #10, then a cotter pin 1/16 x 1/2 where  the arm from the gearshift attaches to the transmission. My gearshift arm has no provision for a cotter pin. There is an integral threaded shaft on the end, it looks like it is 1/8 inches in diameter. In fact, the shop manual shows a nut, speed nut? where the arm attaches. My assumption is spring washer, washer, then a speed nut or course threaded nut? Does anyone know the exact nut and dimensions, like course or fine thread? And if those two washers go on there.

Hi Fourward- I recently removed the 'Hand Shifter' rod from my '81 Avanti II and have it near to hand so I had a look at it alongside the Studebaker Parts Manual. Despite having a GM TH400 Transmission, the Rod appears to be the exact same unit. The photo I took shows the assembled parts as per removal and these coincide with the Parts Manual.  There ought to be a 3/16" 'Clevis Pin' there, which secures with a 1/16" split pin, plus a plain washer, thin washer and 'wave' (spring) washer set. I suspect you have a substituted part down there after a PO lost the original pin and replaced it (with a bolt, perhaps).

Zedman, Yeah, that is exactly what I am talking about. I guess a lot can happen in 60 years, someone must have changed that part. I can get the spring washer and washer, I'll have to look for a nut that fits those threads. Thank you.

Hey Fourward-  Can you remove whatever it is you've got there and replace it with a 3/16" clevis pin an splitpin as per the parts book?

I wish I could! It seems like it is an integral part of the rod. ?? I found 2 nuts in small pile of junk in a drawer that fit! It is a 1/8 inch thread, so they are very small. I plan on putting a spring washer, a washer, then the two nuts, which will lock each other on. I guess that will work.
