Model 66-8 cylinder revolves with resistance

[mi4]

Just bought a SW model66-8 (with internal lock) through ppt. It is still in jail. When inspecting it, I noticed that the cylinder does not revolve as smoothly as my other SW revolvers. It felt like some resistance. Does anyone have the same model and experience the similar issue? Thanks.

To clarify, I meant revolving the cylinder after opening it. The timing and lockup of the cylinder looked fine.

It's likely the ejector rod being loose. It needs to be tightened and it should have reverse threads. Righty LOOSEY, Lefty TIGHTY.
If it's tight, then it's likely debris/powder caught underneath the ejector 'star'. Clean underneath the star and where the star seats on the cylinder.
Oughta fix it.

Thanks Mike! I will try tightening it and cleaning it when I get it home.

It could just have dried up oil in it.
Clean it and add new oil and it might free right up.
In some cases, you might need to pull the crane and cylinder off to get the old oil cleaned out.

mine was sluggish before taking it home. The extractor rod itself has machine marks. but cleaning it and relubing the extractor rod and and cylinder has slicked it up.

What Revoman said and oil it.

By the way, there is a gunsmith specialty tool to use for the ejector rod. I highly recommend buying one as you will likely use it on and off (no pun there....) throughout the revolver's lifetime.

I just clamp the rod in the jaws of a hand drill, and turn it BY HAND.

NEVER USE POWER.

My experience with my 66-8 has been more fouling due to no gas ring causing cylinder to not spin as freely. A range trip of 100+ round requires a thorough cleaning involving removing yoke and cylinder.

Thank you gentlemen for very helpful information.
