Have an EZ-Way RBZ-66 crank up tower that has 2 bearings in the upper
section. The top bearing is a bronze bushing on the mast and has about
3/32" clearance on a side. It requires a good quality grease pack.
About 4' lower is a regular type thrust bearing that uses ball bearings.
The million dollar question, should the bronze bearing be replaced with
a ball bearing type?
