Sorry, we couldn't find any existing installation instruction that matched.

Nose cone impact shaft bearing was worn and caused the bit holder to wobble.

Separated the two plastic housing halves, pulled the reduction gear/impact housing free of the motor, removed the captive rings from the bit-holder and output shaft and pulled the planetary gear set and impact shaft free of the old nosecone. Reassembly reversed the process but added new grease to the gearset and impact shaft.
