Anything other than a proper clean, lube adjust is a stopgap at best. For instance, I have a Yashica screwmount SLR that sat for about 20 years. I did what you suggest with it, and guess what? It sounded - and worked - like new, for a while. The heat and activity moved some lube around. Now the camera still functions at the lower shutter speeds, 500 and 1000 are capping again. Warm it up, or take it out on a warm day, and it's OK.
