It appears to be a reversing starter (run forward or run reverse). The coil circuit for forward will series through a NC contact on the reverse contactor. The coil circuit for reverse will series through a NC contact on the forward contactor. The power wiring jumpers, on the line side, will swap two phases going from the forward to the reverse contactor to allow the motor to run opposite directions. The overload relay(s) will be as any other starter and if tripped will drop out the contactors and prevent motor operation until reset. This is the basics.

It probably has a mechanical interlock in the back under the mtg plate. They can get gummed up and not allow things to move freely.

If you are really going to fix that thing, you need to make your own wiring diagram, take a lot of pictures, tear it apart so you can clean it and bench test it.
Once that's all done, put it back in service and be the hero.

Looks to me like a new starter would be in order. Go ahead and put in for a new disconnect too.

The only thing worse than keeping that POS for one more day is to keep it for two more days.
Rip it out and replace it. Today.

I would guess it is unlikely you would get replacement coils, contact or heaters for that thing if there was a problem with any of that stuff.

Cheers
John

If you can't find it on Fleabay you do not need it.

The actual wiring diagram for that particular starter is somewhat irrelevant. Westinghouse has been gone 25 years now (since 1994), that version of their starters goes back to the 50s or earlier so nothing is going to be available to fix it that itself is not 60+ years old. What you will want to do, as the others have suggested, is just replace it with something new from a trusted supplier and use the diagram of that new starter. The control devices are the only thing in question, so take a look at what they are using (i.e. push buttons, selector switch or relays) and adapt it as necessary using the diagrams from whatever new reversing starter you find.

Yep, that is the black arms at 45 degrees between the coils.

Just get a premounted panel with all the item in one panel (starter, overload, disconnect,...) Any panel builders or motor shop could do it.

It looks to me like that baby needs replaced and also needs to be in a stainless enclosure.

Build your own. Why pay somebody else to do basic stuff.

Doesn't look like that place likes to pay for much.

I'd have planned replacement for that piece the first time I saw it.

That's what I was thinking. I wouldn't get into any long conversations with the management about that starter. Some things are shot on sight.

Yeah, it's dead!

It needed a new one years ago!

You need to look at our preventive maintenance contracts so this doesn't happen to you again.
