The spindle is pressed into the bearing in the nose of the gear case. You usually need a hydraulic press to get them out. If the spindle gear, woodruff key and spacer come out easily (it may need a little prying pressure) you may be able to tap the spindle out with a dead blow/rubber hammer or with a piece of wood on the end of the spindle. If you hit the spindle directly with a metal hammer you can mushroom the end and it won't fit in the needle bearing in the service diaphram.

Its Look likes you have already unmount pos 35 from pos 34 gear case
now first remove pos 55 bearing cap front unter gear case white or black cap on the drawing remove that first then you set(fixate) the small protruding part of the drive gear pos 45 in a bench vice. and then you can remove the pos 5 spinlock hex nut and then the wobble gear comes free. then the rest is to see that all parts have its positions beware of that .
There is the parts list for position neccesary zoom in if you want to see something in the drawing . IMPORTANT if you will now or in future replace the armature then replace also the great gear pos 45 and carbon brushes. if only spindle pos 51 then also replace pos 65 tube chassis. and pos 53 , 60, 61 ,66 , if you will choice the grease a good multi purpose grease and there should be quite a lot of fat inside the machine , replace also little o-rings which have not yet been mentioned concerning lubrication felt and o-rings.

Chuck will only turn side to side after repair of gears box after

I need more information to answer your problem.
The chuck normally has movement turning because of the clutch gear.
It is possible if you had a gear strip or spindle break that there are pieces of metal in the grease that have jammed your new gears. I would recommend tearing down completely, remove all the grease, thoroughly clean gearcase, regrease & reassemble.

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.

Chuck broke on my hole hog how i fix it

The back needs to come off, you need to remove the spindle, press it off the gear, replace it by pressing the gear back on and reassembling. You will need to have your serial number then go to and look up the parts diagram. It looks like the part number is 38-50-5076 which also comes with a new chuck. I just looked at the kit as I actually have one in stock.

I want to know the steps needed to replace a 1/2" keyed chuck.on a Milwaukee 0234-6 Magnum Drill

they make a service fixture for that BUT if you can find a thin wall open end wrench that will fit behind the chuck on the hex of the spindle you can still do it. What you will need to do is remove the left hand chuck retaining screw, put the wrench or similar item over the hex and then put the chuck key in a hole that is about a 30 degree so that you can strike it counter clockwise to remove. That chuck is on tight and there no easy way to remove it like you can do on cordless items.

The motor runs (Milwaukee 1670 1 Drill) but the chuck does not rotate. This is true with both low and high gear. I suspect the gears are stripped but never had one apart before. I removed the top cover...

Hi, chances are the spindle driving the check is snapped. This is quite common. At the same time you might (probably) have some broken teeth on one of the intermediate gears and the narrow gear closest to the motor. I have just dissasembled three Hole hwags for a plumber friend of mine and they all have the same damage issues. The cover should come off fairly easily. Give it a couple of taps with a hammer to loosen it. The cost of replacement parts if the issues are the same is at least $100. Some of the spindles are more (the threaded ones) and will bring the cost closer to $170. remove all the grease as broken teeth will be hidden in there. The only thing I have not been able to find is proper grease to put back into the tool. Hope this helps.

How do you remove chuck?

There is usually a bolt inside the center of the chuck in addition to it screwing on the spindle. The bolt may be an Allen or Torx.

Milwaukee Polisher model 5460. Gear Case Replacement

you need to remove the pad first and then you will find 2 torx screws about a 25, remove them and the plate next if you have a dead blow hammer tap on the side of the gearcase where the screws were and the spindle assembly and bearings will jump out of the housing, then remove the 4 screws holding the gearcase to the motor housing and it will come apart. To reinsert the spindle assembly gently tap back into place with the hammer to reset the gears. Let me know if you need more assistance.
