Product Description

?

This is a Genuine OEM Approved replacement part used on a variety of Milwaukee Power Tools. This Ball Bearing has multiple applications based on your tool. Ball Bearings are used to reduce friction between rotating parts. The balls or rollers take the load and spin, distributing the weight evenly while the minimal contact area of the ball reduces friction. This reduces wear on the tool and allows it to run smoothly. Bearings experience constant wear when the tool is in operation from pressure, heat, vibration and friction. Because of this, many Bearings need periodic maintenance or replacement. This part is made out of Metal and it is Sold Individually. To replace this Bearing you would need a Screwdriver and Pliers.

Removed the nose section from the tool. Removed the internal split ring from the nose of the unit. Tapped the old shaft out from the nose end. Using a long small diameter punch, knock the old nose bearing out. Apply a small amount of additional grease to the inside of the new bearing. Tap the new nose bearing into place & replace intern al split ring. Using the Collet nut without the internal teeth, drive the new shaft into the new nose bearing. Taking the new gear end bearing & the drive gear you removed from the old shaft, drive them firmly onto the shaft. Check for ease of rotation & put some new grease in the cup where the gears mesh. Attach the rebuilt nose section to the body of tool, Tighten the 4 screws firmly. Replace Collet jaws in Collet nut and spin shaft , making sure there are no binds in the rotation. Plug tool in & check for any vibrations. You\'re ready to get back to work now.

Screw drivers, Wrench set

Removing die grinder head easy 4 screws, should have proper tool for screws and a
spanned to remove recessed nut. The problem is there is no way to pull gear you have to heat
and drive the shaft out of the gear. Easy to remove bearings and replace, again the problem
in assembly is heating the gear and seating.
