Looking for some information and pictures (if possible) on my BOYLE DAYTON 62 pump,

1. Two screws that go thru the jar lid (they both have three washers on them. Looks like they could have had a defector plate or something ?
2. need a picture of the linkage for the drain value. It has all linkage but the final one by the access door. In one of the support pipes it has a screw with something that rusted off.

Thanks for the help....Don
