Stiff Parker twist mechanism

[Kwestter]

I have a Sierra Vista that I just assembled and the twist mechanism is very stiff, as in hard to turn.

Any ideas of how to loosen this up without disassembling the pen? I didn't try it before assembly so I don't know if it was already tight or got that way when it was put together.

Thanks,

Ken

The sierra and sierra vista are both very sensitive to any glue inside the tube. Check there first. Glue will cause the barrel to bind when twisting.

Sometimes the internal "grease" gets less effective when stored. "Exercise" the transmission for a few minutes and see if it clears up.

I've added a little of WD-40 and it's done the trick.
