Olympus OM-4 Service Manual

Olympus OM-4 factory repair manual.

This is for the original OM-4. but those servicing the OM-4Ti will also find it useful. The OM-4Ti service manual (see Related Items below) is actually an addendum to this manual, since in most respects the two cameras are mechanically the same.

There is also an Exploded View of the OM-4. Find it in the Related Products below.
