   When you took it apart, were any of the screws loose before you started?  If so, simply putting it back together may fix it.

   Otherwise, you'll have to figure out how the gears work.  Pay attention to "slop" in the bearings, either running loose or sliding side-to-side.  Work the gears by hand, simulating a load on them, and see which ones seem to be "on the edge".  Also consider that maybe the high/low switch isn't latching fully into "low".

   Like Dan, I'm thinking it may not be a gear problem. Rather, it's likely a crushed or worn bearing that's letting the gears separate while running.

   Thanks guys, later that evening I thought it could be worn out bearings too!

   Looking at the diagram there are a LOT of gears in there and I can't easily figure out which combination is low and which is high. (when i opened it i didn't remove anything further so i didn't see the deeper sets of gears.)

   I do a teardown this weekend.....

   Cool.... post some pics if you can. Never seen the guts of a Hole Hawg....

   In fact, take several pictures for your own use, to aid in reassembly if necessary.

   Stuck chuck prevents disassembly...

   Unfortunately you can't remove the spindle (third gear shaft) without removing the chuck first.

   I followed the proceedure for chuck removal (remove 3/16" LEFT HAND THREAD cap screw inside chuck, place chuck body on solid surface (short length of railway track), mount 3/8" allen wrench in chuck and strike ccw with hammer (2.5 lbs sledge) - repeatedly). No luck, its on there for good!

   So I couldn't remove and inspect the low speed clutch. Based on the frequency of the skipping I observed the problem is in the final end drive somewhere (not the x many thousand rpm motor end of the drive assembly). All other gears looked fine and there wasn't much play in the bearings.

   I guess it remains a single speed hole hawg.

   (You can download the parts diagram from Milwaukee's website - and see all the inards.)

   I seem to recall someone had success on a stubborn chuck by chucking some rod in it and an impact driver and letting the driver do its thing.

   Are you sure that's the right direction?

   ccw

   I am sure that's what the video on youtube showed. (I can see the guy now putting the drill in the vice and whacking the allen wrench ...)

   Did you check carefully -- I seem to remember that some chucks have a set screw in addition to the left-hand screw in the center.
