FIGURE A. Your GP/GL-Series loader is equipped with composite, greaseless bearings at all (12) pivot points. These high-quality bearings should not be confused with plastic bushings, sintered bushings, or metal-backed bearings. Composite bearings are made from an ultra-strong fiberglass composite that has twice the compressive yield strength of plain carbon steel. Their greaseless feature is due to a Teflon-impregnated liner that is interwoven to the bearing’s inside diameter. The bearings are de- signed to last the life of the loader and the pins that rotate in the bearings should exhibit practically no wear.

FIGURE B. Even though the composite bearings on your GP/GL-Series loader have excellent resistance to dirt particles, the (4) pivot points on the bucket have an added feature. The two lower bucket cylinder piv- ots and the two mainframe-to-bucket pivots are equipped with pin seals on each end of the bearing housing. It is these four pivot points that are usually down in the dirt and grime, but with a GP/GL-Series loader, you won’t have to worry about pin failures again!

FIGURE C. Should any of your bearings have to be re- moved, this photo shows the tool that is available to remove and install the bearings properly. They are available for pur- chase, you just need to tell your dealer or Miller Loaders the model of loader you have. If you’d prefer to make your own, here are a few things to remember:

•The nose should be 1/4” longer than the bearing

•A 1/4” bevel on the end of the nose

•The shoulder must be just slightly smaller than the out- side diameter of the bearing

•The diameter of the nose should be about 0.005 less than the inside diameter of the bearing
