Sounds like something isn't sitting right and when you tighten things it locks up . Who did the assembly on the trans itself ? you buy it that way or build it ?

 

Yes, this can be very dangerous, I'm pretty sure this is how my friend lost his finger while working on his FX starter...be very careful. I would disconnect the battery for sure! He said it hurt like hell, somehow he got his finger somewhere
where it shouldn't have been, and chopped it clean off!! Index finger too!
Yikes!

 

I bought it assembled. They said the gears were good, and they changed the throw out bearing I did look in it from the top cover and the gears did look really good, they left that cover loose so I could look, not that I really knew what to look for

Its hydraulic clutch tranny btw if that might matter...

Maybe its in between shifts or something? that kinda not sitting right maybe?

I did have to file a spot on the threads of the shaft cause there was a ding. Maybe in shipping it got dropped on the shaft and jammed something?

geez maybe I should just hammer it with the impact....

When I took the clutch off the old 4 speed, I used the impact but the nut came off without much trouble. The clutch wasnt hard to get off the shaft either. I wonder if the last guy left it not so tight too. It is "fairly" tight where it will still move ok when I push the kicker, maybe thats good enough with the lock tab on the nut, and its a lefty nut too...?

 

The gears in there looked really good.
Im going to remove the tranny and have a look inside. has to be something inside jamming up.
It seems torquing on the main shaft has made it jam. That bothers me... hopefully it will be something just needs simple adjusting. I checked out some youtube videos on dissasembly, and it accually looks fairly strait forward. Ill let u know if I find it

 

guess I'm showing my age but when I was working on my old Pan or Shovel, whenever trying to remove or tighten the clutch hub nut I used a homemade tool that me and everyone I knew had.

We would take and old clutch friction disc and a 18" piece of flat steel. Drill two holes in the "Handle" and the clutch disc and bolt them together. Now slip the improvised tool over the clutch hub fingers and rotate the hub until the handle rested on the ground. Install your socket and wrench (or impact) and have at it. I still have my clutch hub nut tool in my tool box.

 

What he said! I used to have one of those also.

 

Went to my Dealer and asked to purchase the 'primary locking tool.' Was asked how many people I thought asked for that in last year. I shrugged my shoulders. "One," he stated. "You." "Use an impact wrench." I did and have had no problems with nut.

 

ok I took the tyranny back out. Looks like there were 2 different issues. I opened the top, and turned the shift drum, and it isnt locked up anymore.
I could see on the sprocket side of the inner primary some small scrape marks where the sprocket nut looked like it was hitting. There are grinder marks there where someone had ground away some material so the sprocket wouldnt touch and bind up with the 4 speed. It must not be the original primary cover. I ground it down a little more where the marks were and tightened everything up with the impact. Working great now. (oh yeah I glued in the key)

Thanx guys for all the think tank
