Locksmithing/Older Yale Doorknob Assembly


QUESTION: I have an older (30-40?)Yale push-button exterior doorknob that has been removed due to excessive play in the knob.  Inside the assembly there are numerous plates and springs.  I'm attempting to reassemble the knob to reinstall it and cannot figure out how the multiple plates and springs go back together.  Any advise or parts diagrams available?  I live in an extremely remote area so running to the store (400 miles away) for a new knob is not an option.

ANSWER: Yale made a boatload of different locks over the yearw.

Any chance you could post a pic or two?

If I can ID the model, I should be able to find you a service manual.

QUESTION: Thank you for the prompt response!  Here are the pics.  I couldn't find any model number on any of it, nor could I find a pic online that closely resembled it.

I have the Yale 5300 lock service manual for levers, which are substantially the same as the knobs.

Or send my your email address and I'll send you the pdf.

It basically shows how all the parts fit together. You should look at the entrance lock version.
