Hey Guys,
Trying to figure out how to put this and of the motor back together. Was in pieces when I got it. Trying to restore a Columbia Standard X Front Mount phonograph. Not sure if there are a few spare gears in here or they are all needed? Hopefully one of you have put one together before. The end cap is on the bottom of phono to secure all the gears. Thanks for any assistance!

Well-- Not sure how much help this might be. It's hard to get pictures of the gears since most are sandwiched between the motor plates- But-- for what it may be worth, here are a few pics of one of my motors.
In the 2nd picture- where the bright reflection is--- The racthet pawl is mounted right below that gear and engages it to stop the backwind- You can see that wide-tooth gear in the 3rd picture.
In
your 1st picture you can see where it mounts- The larger shaft that has the hole in it- The ractchet gear is secured with the pin that is laying at the top right of your picture.
Hope this helps a little.

Aha!, your photos have answered a question I had about my Columbia AU motor (essentially the same as your motor).
It looks like, at some time in the past, the hook of the ratchet pawl had broken off and someone had added a blob of metal to the broken end and affixed a section of safety pin to push the non-hooked end of the pawl into the ratchet gear teeth. This worked, but the free end of the spring was wearing out the gear.
I couldn’t see a way an original spring could have been mounted, so I just improved the earlier modification and it works fine.
I do now see from your photos that the pawl is intended to rock on its pivot so that either end may engage the ratchet gear, with no spring necessary. A very neat design.
If I ever have the motor apart again, I will make a new, proper pawl and dispense with the spring.
It does look as though you have two of the large, pawl-carrying gears though, and I think you just need one.
See photos below, one of which is your unmodified gear and pawl.
