Auto Wrench Belt Replacement?

Wed 13 September 2017 by pj

Some years ago I received a gift of a Black and Decker AAW100 Type 1 'Auto Wrench'. It's nice for the lazy man (which is definitely me).

I recently pulled it out of the toolbox, only to find that it didn't work. A screwdriver and 5 minutes later and it seems that the issue is that the belt is broken. Searching on the internet, it's a common complaint, with no real good solution.

First job is to figure ou what needs replacement: Some specs:

  • Tooth width: .05" = 20
  • Belt width: .1160"
  • Belt length : 1.1165 + 1.2440 = 2.3605"
  • grooves = teeth = 19 *
