Re: Makita 8406C Gearbox oil
It uses grease to lube the gearbox. makita supply their own grease so you should be able to get a small tube from your local dealer. You don't have to use Makita grease though, just general grease should be fine. Not too thick and heavy, or too oily and light. I know that sounds a bit vague. Do you have other machines that you have grease for? SDS hammer drills, saws, any small power tool like that will use a similar type of grease.

Hi Mike, how old is the drill and how much have you used it? Hopefully it is only the brushes, it is carbon rods with a piece of copper braid connected to it, there might be a spare set (2) in the original box. These parts do wear out and is replaceable. Check your manual on how to replace them. Hope this helps.

This is a light weight cordless screw driver, so it all depends on what material you are trying to drill. It will probably drill small holes in wood and possibly in softer metals. It is made for light duty work, so again, it depends on what the material is, so if you are reffering to wall board such plaster board or sheet rock, it will drill smaller diameter holes.
Unless you have the part in hand, which you could take to a specialized machinery or spring supplier to see if they could match it up, the only other way to get the correct part is to contact ryobi direct and talk to their parts department. They will be able to tell you the part number, and if available, send you one out direct from their warehouses.
You will need 2 spanners ( the size vary's from differant models) and A screwdriver (generally phillips/star). Remove the screw that is inside the mouth of the chuck (it screws throough the back of the chuck and into the chuck shaft). Then get your 2 spanners - One goes on to the chuck and the other goes onto the shaft that the chuck attaches to. Turn the chuck anti Clockwise. This may be vary hard to do as somtime they rust and cease and you may need to brace the second spanner in a bench/table vise and use a hammer to gently tap away at the 1st spanner (the one holding the chuck). I find that spraying a litlle penatrating oil on the screw and the shaft an hour before attemting helps about 80% of the time.
OK I assume that by chuck snapped off the spindle is broken and if so there are 2 the low side spindle is part #324170-4 and the high side is 3241699. I believe the gears are a press fit on the spindle. the complete RAD part# is193316-1 and if the chuck only is damaged that number is 193319-5 and from what I can see it is a taper fit on the spindle, I didn't see a chuck retaining screw. If you would like to view the tool go to Makitausa.com and type in your model number and you can get a breakdown and also a list of Makita dealers in your area. Good luck and let me know if you still have any problems
Before connecting a drill press to a power source be sure that the voltage supply is the same as that specified on the nameplate of the tool. A power source with a voltage greater than that specified for the tool can result in serious injury to the user, as well as damage to the tool. Using a power source with a voltage less than the nameplate rating is harmful to the motor. Also, when operating the drill press, use safety equipment including safety goggles or shield, ear protection and protective clothing including safety gloves; Keep the area free of tripping hazards; Periodically check that all nuts, bolts and other fixings are properly tightened; Never use your hands to remove dust, chips or waste close by the drill bit.
If adjustments are necessary, follow the this procedure: Spindle side-play can be minimized by adjusting the locknut located on the left side of the motor unit 1-1/2 inches behind the spindle and towards the bottom of the motor unit. While moving the feed handle up and down, tighten the lock nut until the play is minimized, but not so tight so as to restrict free movement of the spindle. The spindle should return by itself to the full up position. The drive belt tension may be adjusted by removing the top cover and then loosening the two nuts on either side of the motor pulley. Adjust the motor position and tighten the nuts so that moderate finger pressure against the belt causes it to deflect 3/16" to 1/4" (see Figure 6). Excessive belt tension may result in damage to the bearings. Note: Belt tension can also affect the generation of "noise" in the drill press. Although it does not affect drilling accuracy, it may be desirable to adjust the tension for minimum noise. The spindle has been generously oiled at the factory. You may have to periodically wipe off oil that makes its way down the spindle.
