O ring
Broke off the locking pin on my Dewalt chopsaw. Ordered a new pin and O ring. Parts arrived slowly due to supply shortage, but they work perfectly in my saw.

, On board blade changing tool is all you need
Parts Used
Loosen the blade guard to swing it out of the way to remove the broken pin and installed the new one with a new O ring (lost the O ring so had to get a new one). The blade removal wrench is right with the saw so no addition tools are needed :o)
This is the third time I have had to replace the locking pin so it gets easier and faster each time
