I realize off the bat this runs the risk of doubling my problems but here goes. I currently have a z1j-hda-13t 450w impact drill which motor seems to be seized.
I was wondering aside from being less powerful, would it be feasible to replace the 450w with the 400w motor from another drill? Or would the drive chain having been setup for a 450w create to much torque on the 400w and just burn it out?
I know someone will say why not just use the 400w drill and I have been. But the overall size of the drills is marginally different such that some of the attachments won't fit in the 400w's head and the head from the 450w won't fit in the housing of the 400w. Hence the above question.
Just as a p.s. Both drills have a a hammer and screw option.
