Don't bother unless you plan to make lens repair a sideline business. It's a
PITA and this lens (the Zuiko 50/1.8) is commonly available for $20-$30.
Instead, save it for viewing slides. It makes an excellent loupe, altho' it
is necessary to move it or the slide around a bit to view the entire frame.
By pure serendipity, I discovered that a UV filter plus a generic
collapsible rubber lens hood provides the perfect slide-to-lens distance for
sharp focus, with the lens hood collapsed. And you can snug the corners of
the mounted slides into the lens hood for easier viewing.
Generic advice, not Zuiko-specific: If you decide to disassemble the lens
and don't want to buy special tools, look for small slots, notches and holes
where makeshift tools such as small screwdrivers or pin punches can be
inserted. Use these to loosen the threaded retaining rings that hold the
elements in place. Most lenses can be disassembled down to the diaphragm
without special tools. It's easier to leave the diaphragm in place and
flush it clean with a solvent.
Personally, tho', I can no longer think of many lenses I'd bother with
myself. If it's worth salvaging, it's worth doing right - which means
sending to an expert like John Hermanson. The last exception for me is a an
old Canon FD breechlock lens which has a switch on the rear which
facilitates manual diaphragm operation with the lens mounted on a bellows,
manual extension tube or reversing ring. The lens isn't commonly available
anymore, takes great pictures and it wouldn't be cost effective to have
someone else repair. So I'm doing this one myself. But never again.

...the 50mm f1.8 lens has sticky
diaphragm blades...I've managed to get the back off, but now I'm stymied.
How do I get the
rear elements out so I can get to the blades.
