Review on πŸ”§ Supco TB123B Spanner Wrench: Ultimate Tool for Plumbing and HVAC Systems by Richard Marriott

Revainrating 5 out of 5

Used this to remove a whirlpool wrench 21366

. Removing a wrench nut is PITA, you really need that wrench so you can hit it with a hammer. One trick to removing the nut: not only do you need to spray penetrating oil on the threads you see on the 389140 drive block the wrench nut is screwed in, but you also need to spray oil under the wrench nut where it meets the top tab on the inner pan . The bottom of the wrench is flared to fit the internal tank expander and it will likely get stuck there due to corrosion so you'll have to break it up and also try to get into the invading oil. Hit the top of the wrench around the nut and then try hitting it with a hammer to turn it alternately and it should loosen.

Pros
  • . Wrench
Cons
  • . Was damaged.
