I took the right angle drill assembly apart by listening the bolts on the side , took the broken rev coupling out and replaced it with the new rev coupling that I ordered from ereplacementparts . Put the rightangle attachment on the drill and tightened the two bolts back into place . Took about 4 minutes all together ..
