wingless’ Milwaukee 0224-1 Magnum 3/8″ 0-1,200rpm Hole Shooter Gear Lubrication

The gear lubrication in my Milwaukee 0224-1 Magnum 3/8″ 0-1,200rpm hole shooter was over 30 years old.

The Product Support Bulleting TIY #383 specifies that the correct lubricant for this tool is Type E grease.

A one pound tub, part number 49-08-4122 was purchased.

The gear case was opened by removing the front three screws. The old grease was removed. New grease was forced into all the bearings by hand, then deposited around the case in a manner similar to the old grease. The case was then reassembled.

The tool has a very nice feel now.

Nice work 👍 what did you use to clean out the grease? It is good to see quality tools cared for. I recently repacked my metabo cordless 5″ brushed grinder housing also. Funny enough the grease seems to mostly spin off and leaves almost nothing on the gears but I doubt that would be an issue as all it really needs is a film, which probably melts on and off with heat. I used high temperature/pressure moly grease which we use on our excavators/trucks and after a few minutes of letting it run it feels brand new again (also sanded the armature, cleaned out the motor which was packed full of magnetic dust which kept putting it into overload protection mode)

Photos are of when I had just opened it all up. You can see how the gears look as if they have been wiped clean.

Thanks. Nice job on yours too.

The old grease was scooped out with a small, flat screwdriver. A paper towel was used to wipe the surfaces clean.

A toothbrush (I used the wife’s) was used to clean the bearings, the gear teeth and the entire housing interior.
