Repairing a makita 6901d cordless impact driver, when under a heavy load,it smokes and smells burning,still works under a light load. would that be the motor?
It could be the motor or the switch. You can usually determine which one by opening up the drill and inspecting the parts. Quite often you can visually see which one has overheated and started to smoke. Sometimes you can identify the offending part by simply smelling it. Once you determine which one is the bad part you can replace it.
Repairing a Makita 6095D clutch Question by Charly Small 08/11/2009
The clutch will not work, broke or slipped out of place. Since the clutch will not work I can not take the chuck off. I took the screw out, put an allen wrench in the chuck, ran it in reverse to try to pop the chuck loose so I could get to the clutch. But the chuck slips since the clutch does not work...In between a rock and hard place here.
Unfortunately there is no easy fix for this problem. Your best bet is to sacrifice the change ring, part #410936-9. Carefully cut the ring off of the drill. Then you can open the housings. Clamp the spindle, with the chuck attached, in a vise with some soft jaws so that you don't damage the spindle. Now you can remove the chuck for reassembly after the clutch repair.
