I'm not sure but after taken both retainer pins out try to pick the lock to open, hold it open and them see if plug housing come out. It sound like to me the shackle bolt may keep it from coming out.....Timothy.......

Attachment 17731Attachment 17732regular 870 on left 872 on right . where circle is you can see keeper, they possibly forced keeper in at angle, but no way to remove. the keeper will go thru the hole,doesn't make sense. i have 2 of them so i will drill and tap the open one and then hope it's master keted and make key off the drilled one.
Anyone keying a corbin like this one ? if you do not have a blank a 1a1a1 best blank fits very well. just some fyi

keeper removed, used 1/16 punch ,drilled for 6/32 screws,tip of a key stuck in plug ?

I just noticed that your lock has the old style plug retainer with the screw into the side and the long adjustment screw that limits plug rotation. I thought they switched to a pin that rides in a groove milled into the plug sometime in the 50's or 60's--I have a 850 made by Yale & Towne that has a pin which has to be drilled and pulled to rekey the lock. All the 870 locks I have are also Yale & Towne, but they have the same plug retainers as your 872. Since yours has a lowercase Yale logo, it is much more recent, at least the Eaton years or later. Are they still producing these today?
i think they changed to the pin holding the plug in very late 60's early 70's. After they removed the lubricate with graphite words in the late 60's.
Maybe Pete or BBE would know,i'm just guessing. If you or anyone else knows where i could purchase 4-6 of the 870 plugs ,with the older screw retainer
i am interested or trade i have new plugs with ge keyway for the screw retainer 850,840 yales. i think they both use the same plug ? As long as the keyway is not to restricted so i can get blanks for them.

plug info--it could be the 6 or 7 pin, maybe someday. Think i'll just make up a longer driver,that should work
Attachment 17747Attachment 17748Attachment 17749 THANK YOU GENTLEMEN,APPRECIATE THE HELP

should not have to take another apart, unless there is a problem,like the first one.
thank you,gentlemen,your help was appreciated
When you say restricted, was it one of the G, S or T family multiplex sections or something different? Please see thumbnail attached.

thank you ,Pete, i even tryed 2 times on the gst and just wasn't enough meat. they kinda came apart. i did make the driver up and it works.
still have not figured out how they got these padlock 9/16 shackles in and with the same keeper as the 870's.
