I disassemble, clean, lubricate and re-assemble a Stanley 1/2″ Drive Pear Head Quick Release Ratchet Wrench (model 89-819 Cr-V). I bought this wrench for $5 at a thrift shop. It worked fine. But I love taking things apart. And I am always interested in seeing the different mechanisms in these ratchet wrenches. So I took the opportunity to make a video. I will probably be keeping an eye out for more ratchets as they are kind of fun to work on. I used Super Lube Synthetic Grease to lube the main drive parts, and Tri Flow spray oil to lube the quick release.
Old, dried grease is the main cause for ratchet wrenches to start slipping or stop working well. And lack of lubrication causes the small ball that holds the sockets on to fail.
