The Cessna manual linked in my other wheel thread had a diagram for the Goodyear 5.00 X 5 wheel for tube tires. Unfortunately the bearings that were in mine did not match those in the diagram. Mine are Bower LM67048s that have an attached seal on the outer edge vs. using the separate felt seals as shown in the diagram. The installed seal covers what would ordinarily be the wider opening at the end of the rollers where grease would be applied. Is this seal removable? I was unable to find any seals or bearings online that match, and am hesitant to attempt removing the seal if that is not in the design. Otherwise, how do I grease the bearings?
