Old Zenit shutters stick after sitting for decades, but a CLA changes everything

Honestly, I've noticed a huge before and after with vintage Zenit cameras that come in from estate sales. The shutter curtains often feel like sandpaper and the speeds run slow because the old grease turns to glue. I did a full clean and relube on one from the 70s last month, took about 2 hours, and the difference was night and day. It went from a paperweight to firing at 1/500 with a crisp snap. Anybody else see these Soviet cameras respond that well to just a basic CLA?

Honestly, the 2-hour mark is pretty close to what I've seen too, but that 1/500 speed sounds a bit fast for a stock Zenit after just a CLA. Most of the ones I've worked on top out around 1/250 reliable, even after a full relube, since the spring tension just gets tired after 40 years. Still, you're right that the change is massive, it goes from a brick to something you can actually shoot with.

Read in a repair group that the Zenit springs were never that strong to begin with, even new. One old Soviet camera tech swore they tested them at the factory at 1/400 but set them to 1/500 just for the marketing numbers. After a few decades of sitting around, that tension just droops. Makes sense that you'd see more consistency around 1/250 after a good service. Either way, you're spot on about the transformation. A tuned Zenit is still a heavy, clunky thing, but at least the mirror doesn't slap like a loose door and you can finally trust the shutter for street shots.
