BBE wrotePete is correct. You might try obtaining an older catalog as they used to have an explanation of how the cylinders worked in the front.
BBE.
Thanks for the input.
Regarding a Yale retail catalog; I’ve looked in the local library, the internet and Ebay without any success. The most success I’ve had is from you guys sharing some pages here and there. Any suggestions where I might find an entire catalog? Even if it was just basically a transcript would be fine.
As I spend time with these Lever Tumbler and Push Key locks;
I keep thinking that there must have been a manual to describe the repair process and identify the correct tools. However, your comment helped remind me that back in the day, many specialized skilled occupations were learned in the process of Apprentices to Journeyman to Master. So it would make sense that Yale would not bother with printing a locksmith repair manual.
Different times require a different mind set.
Have a great weekend.
