Sector shaft nut

Anyone know what the thread size is on a '55 Ford pickup sector shaft to pitman arm is? It's about a 7/8" something ? I lost mine.

 

here is easy way to check : take a open end wrench and slide it around the threads,kinda like a tape measure.

 

I need to know the threads. I Think Ford used something weird again.??

 

they sell "thread checkers" at the parts store, pretty handy to have in the tool box. try the ford truck forum.

 

butch.....55dude is right...get a thread pitch gauge , you will use it many times over your hot rodding career . not to bust your balls , but if you have the steering sector there , and you can not figure out what size the threads are , we are doomed. this is actually very basic stuff that you would learn in high school shop cl***...if you were in high school in the 50\'s or 60\'s

i don\'t know you , but if you are of the MTV generation , i apologize

 

Hey Twevor, not to bust YOUR balls, but there are NO threads on the 55 pickup sector. It takes a through-bolt to pinch the pitman arm. (Open mouth, insert your foot)

 

O.K. Boys: Settle Down: It's a 7/8"-14 and right the original WAS a clamp down BUT I,m running a '41 pitman arm. SOO --EVERYBODY is right! Thanks Guys

 

i\'m not gonna do that , but i do know where i\'d like to put it

 

So, it was a trick question then? Or does a '41 sector shaft fit in a '55 steering box?

 

That is an interesting question. If the early sector shafts will indeed fit into the F100 steering box, it does open up more choices for a pitman arm. Does anyone know for sure?

 

Early cross steer sector shafts for in 48-52 F-1 boxes.

every hot rodder should have tools. every toolbox should have a set of tap and dies. within that complete set, there should be thread guages....how can you even start to work on cars without these basic tools?

not trying to offend, but working on suspension indicates some advanced mechanical ability - it doesn't make sense that you don't have a way to cut threads, or thread holes.

Yeah, a lot of the old pitmans will fit. I just used a SMALL triangle shape file and filed some flats on it to index the arm on the sector shaft.

 

I'm thinking Butch has an F-1 box, not a '55 F-100 box. Show us a picture Butch.
