Hi Folks:

I have had trouble with the Parker- style twist transmissions on some higher end kits. When turning them to retract the point, they simply screw off. I also, less frequently, experience a similar issue with extending the point - apparently something is not grabbing whatever it is within the mechanism that pushes the refill forward. I would think the source of the problem is the same.

Any ideas as to how to fix?


Thank you!

You need to turn them on to get a tighter latch when you screw the finial on. If the transmission is tight enough when you start it will work ok unless you over turn when extending or retracting the point.
 
Thank you Smitty. I have done that at the risk of over tightening them. I will tighten even more.... thanks.
 
Which pen kits are you working with, Tony ?

PM sent - no specific kit identified. Single-tube, twist-top.

Maybe it just requires more tightening. We will see. Thanks!

Usually you turn them to a point where they "latch" then turn back slightly. After that when you extend then retract they shouldn't turn far enough to unscrew the next time you try to extend unless you force them while retracting. At least that's how my Royales seem to work.

I always take a pair of pliers and give it a hardy twist. when I sell a pen like that I inform the person that is how I did it and show them how to change and reinstall.
 
I have had the same problem with customers unscrewing the transmission, when they don't know which way to turn them. I just put a small dot of blue loctite on the threads, when I install them.

Then how do they replace the refill:confused::confused::confused:
 
Thanks Dan. I was thinking of doing that, but "feared" not being able to unscrew the transmission to replace the ink refill. I know the blue LT is less permanent than the red, but how did you overcome having to replace the refill? It is likely that I don't completely understand how the transmission works. Thanks for the reply.
 
Sorry, for the confusion with my post. I only do this with component sets that the refill is changed by unscrewing the tip of the pen.
