Has anyone drilled and tapped a CAT composite roller with a grease fitting? Im getting tired of replacing squeaking bearings or rollers that popped off due to dry bearings falling apart so Im about to tap each roller with a grease fitting and set screw. Remove the set screw fill with grease until it comes out the set screw hole. I know they arent sealed but if you could at least keep them greased should last a little longer. Thoughts?
Go to "Lawn Site", then heavy equipment, then rc 30 drive train issues, there is a guy who has done what you are thinking. Lots of good pictures too!
