Once you got the center spacer out you might have wondered to yourself....self, how is the grease actually going to reach the bearings? Here's the trick. You cut some grooves in the spacer as shown in the photo from Old Sarge (left).
The specs are: A ½-inch band around the middle of the spacer 1/32-inch deep. Two slots, 180-degrees from each other, end-to-end, 1/32-inch deep.
The combination of grooves allow grease to move through the zerk fitting then 'around' the spacer until it finds the horizontal slot. It'll flow along the horizontal slot then down between the center and outer spacers and into the bearings. Cost of having a machine shop do this work for you should be around $35. Some shops have a minimum charge so be sure and get up front pricing so there are no surprises. |
