Fix a broken chuck assembly on a Milwaukee 5303-20 rotary

On a lark I purchased a Milwaukee 5303-20 rotary hammer drill that was missing some parts behind the chuck. I am purchasing the missing parts, (collar, rings, ball bearings, springs, etc.) but now wondered if it is hard to assemble the quick change parts I just ordered. Would this operation require special tools or skills?
Thanks. The chuck itself is fine, just what it attaches to needs fixing.

Quick change clutch is locked


Push the rubber sleve off the drill bit and up the drill bit then the plastic ring. release the clip around the spindle. Slide the clip and chuck sleve forward and remove the ball sitting in the spindle. You should then be able to pull the bit from the machine. If it does not want to come hold the bit in a vice and tap the spindle off the end of the bit using a suitable punch. Rebuild chuck in reverse.

How do I remove the sds chuck to fit the standaed chuck


The SDS chuck is an intergral part ot the rotary hammer drill assembly. You can get a standard chuck that has an SDS fitting on it and that will fit into your drill and give you standard drilling capabilities.

The chuck on my Hilti TE 24 hammer drill keeps falling off. I doesnt appear to be anything broken. Either there is a missing snap ring or I am just not putting it back on correctly. Any suggestions?


the header list 2 different drills, if yur chuck has a colllar with a quick release, I would suggest thoroughly cleaning and then using a lubricant, usually there are steel balls that lock into detents in the spindle and they might be stuck the collar should move freely.

Put drill in revcerse and the chuck comes loose dropping the bit out


Yup, that is what happens. You can lessen that by really cranking it down, but it is an issue with most hand tightened chucks, and does not indicate a mechanical failure. I sometimes miss my old, heavy Milwaukee wrist-breaker with the keyed chuck. If it is just too much to live with, you could get a drill with the click in hex chuck or put a Jacobs keyed chuck on your hammer drill.
Anyway, I hear where you are coming from and share your frustration.
