Hello All.

I just picked up a very clean Turner Reich triple convertible in a Compound shut ter. The shutter was firing only at the fastest speed, so I took the face of th e shutter off to discover that the lever arm, and the pneumatic air retard pisto n, that governs the speeds, was stuck. I applied some pressure and it freed up. I then removed the cylinder and piston, cleaned and replaced them.

The shutter is working again, but the slow speeds are SLOW - too slow. The pisto n is moving freely in the cylinder, so what should I look at? Should I put a TIN Y bit of very light oil on the piston, or that I big NO-NO? Or would I be bette r off lightly oiling the joints/pivot points on the piston-lever-governor arm?

Thanks in advance. Sheldon
