Bad tranny???

[Gofer]

I got a Sierra twist back today from a good customer whose pen will not retract. I tried it out and when it is extended the tip is about 1/4" past the nib. The Tranny rotates smoothly and works normally but the tip is still out when it is "retracted".

Not sure what happened but I am curious what kind of fix there is other than just replacing the tranny.

All help welcome.

Did you check if the spring was installed?

 

[Gofer]

Yes the spring is there, it looks normal but does not work right.

Did they just change the refill? I had a couple that the refill tip was just a hair too big for the hole in the nib. It wouldnt go back in unless you pushed it.

No everything is the way I assembled it....


OK found a problem, a skinny piece of black plastic about 1/4" long was in the way, where it could have broken off of I have no idea. The refill spins freely against the tranny but when assembled it works normally.

Not sure how this will stand up long term, where is a good place to get some spare trannies?

Ernie at Bear Tooth Woods had Sierra transmissions at one time, but I don't see them now . The Village Workshop has them listed but I've never done business with them. I would make sure the transmission length is what you need (2.72" or 2.37" -- tip to tip -- product photo looks like the 2.37"). I have "sierra" type pens with both lengths and not sure if consistent length from one vendor or not.
