Model 60 sight change

[kelljor]

I got a new model 60, when adjusting the rear sights I noticed that I could not feel or hear clicks while adjusting the elevation. I contacted Smith, they sent me a whole new sight assembly. So when I checked it out before ripping the gun apart, I couldn't feel or hear any clicks on the new one while turning the elevation screw. I also noted that the underside of the screw, the bottom, has groves in it in an X pattern. What bothers me is that I can't feel the clicks while turning the screw on the new sight; just like the old one.
I searched the internet for any info; all I could find was info on just the leaf, which is not what I want to do.
Any advice/input/info would be greatly appreciated. TIA.

The clicks are made by a spring loaded plunger in the head of the windage and elevation screws. I would put some penetrating oil on them and let soak overnight, then turn the screw back and forth several times to get the plunger moving. Once the plunger is working freely, you will have clicks. You can do this on the original sight without changing anything. Can't hurt, might help.

UPDATE I took it apart and found the following; apparently the "indents" on the elevation part consists of a small "bar" built into the top of the frame and two intersecting grooves on the bottom of the sight adjustment screw (I am referring to the elevation ONLY). One line runs parallel to the screw slot, the other crosses the slot at an approximate 90 degree angle so when the screw is turned the groove drops onto the bar (that are the indentsReally simple. The grooves on the original seemed a tad narrower than the replacement; I replaced the whole sight assembly and now I can feel the indent.
Hopefully this can assist someone who runs across the same problem.
Can't say this works the same in the larger frame guns as I have never taken one apart.

It is not uncommon not to hear clicks. On the older models, the clicks were more prevalent, and on the newer ones they don’t always click. You need to turn them slowly with a small delicate screw screwdriver that fits properly, and you will feel when the plunger is pushed into the groove.



Another little trick would be approximate where you think the pin should click and turn the screwdriver slightly in the backwards or rewards direction. You will sometimes feel a little resistance, knowing that it has locked in. You need to rely on feel rather than an audible click sometimes.
