ridgid reciprocating saw failed 

Which part was it? My original one did that 3 or so times before they gave me a refurbished brushless. Now that's broken the same way and depot doesn't do repairs anymore. Closest place is 25 miles away

It's probably the "Gear Assembly" part which must be worn out

Same thing mine is doing got plaster in it opening to the motor needs a screen or something so is it the motor or gears

how did you repair it?
