Would not hammer
Watched U tube videos. Guy in Europe repairs tools and makes great videos. Got parts breakdown drawing from Mfr website. Broke down tools, found broke parts, ordered all needed from eReplacementParts and put tools back together according to video. Tools broke due to user not following recommended maintenance of grease every 6-months.
Note: lock ring pliers are not the same as snap ring, and really help with this tool.
