Timing question
« on: February 10, 2016, 07:43:27 PM »
Took possession of a new Pietta Eliminator "C". When dry firing with snap caps everything works fine. When lowering the hammer by hand the cylinder unlocks and moves slightly counterclockwise.
Any suggestions? Is this a warranty problem or an easy fix?

Thanks

Are you going to full cock before lowering the hammer?  If you are lowering the hammer from the half-cock position that is your problem.

Negative. Going to full clock, cylinder is locked in place, then if hammer is lowered by hand the cylinder moves slightly backward.

I would go with the warranty fix, a pistol in that price range should work. Sounds like a weak bolt spring and perhaps poor fitting of parts.

Sounds like the gun wasn't locked up in the first place.  Rather, the hand (rather than the bolt)  is indexing the cylinder and it is falling away when the hammer is lowered.

Get a light on the bolt to see if it is, in fact, locking up.

I'm sure there are different opinions on this, but many feel it is satisfactory to have inertia carry the cylinder to full lock when the timing of the secondary ratchet falls short.

So, Does it lock up when run at normal speed???  Does the failure to lock up only occur during very slow operation?  Once again, are you certain that it locks up at all?

If this is new I would send it back.  Is it an easy fix?  Yes if the person knows what he is doing.  NOOOOO if he doesn't.  To check bolt lockup slowly cock the hammer until the trigger catches the full cock notch.  Then reach up and twist the cylinder clockwise.  If it moves a bit and you hear the bolt drop the timing is off a bit.  One other thing to try.  Cock the gun and then try turning the cylinder COUNTER clockwise.  Sometimes Pietta bolts are just a tad wide and don't fully engage the locking notch.
