Works smoother now than it ever has
John, Where do we send our OMs for repair? Should John H. and Clint look
for part time work at the 7 Eleven? Were I attempting this I'd still be
look for that ball bearing. Great to hear of your success. Bill Barber
Thanks Bill . . .
Before starting the "surgery" I had visions of trying to find the ball
bearing . . . or the spring and pin . . . during/after disassembly. The
spring almost got away as I was reassembling it.
Looked at the exploded parts view (thanks to Mark Dapoz) and made a
reassembly risk assessment. Disassembly isn't usually that hard; proper
reassembly can be very difficult. Akin to falling from a ladder; not the
fall that hurts; it's the sudden stop at the end. Took the risk as I want
three 35mm bodies on hand this next weekend for a wedding shoot; having a
fourth body as a spare makes me feel better.
Used a ring-light large magnifier on a stand and worked in a shallow tray
to limit things rolling off very far. The only tools required were a pair
of forceps (handling the pin and spring) and very small jewelers philips
driver. The critical part was watching the pin and spring, and ensuring
the registration of the shutter speed gear train at the bottom didn't get
out of whack.
The SS Ring only has the detents and a slot for a tab that mates with and
turns another ring under it . . . the second ring under the SS Ring has the
teeth that drive the SS gear in the bottom of the camera . . . and
fortunately it doesn't have to be removed (but it is loose at that point
and can fall out). Were it any deeper than removing the flange and SS
ring, or if cleaning and very judicious lubrication of the detent
bearing/surfaces hadn't solved the problem, it would have gone to one of
them. It's about as deep as I want to dig into one and [seriously]
**don't** want to do this routinely.
John H. has overhauled two bodies for me (he's closer than Clint) . . . did
great work on both.
Thanks,
-- John
