Has anyone experimented with rubber type wheel bearing seals? Cleveland supposedly came out with a new rubber seal about a year ago, but so far no one has them in stock. Finally in frustration, I purchased Timken seals, PN 472737 to try. They are dimensionally correct, but their secondary dust seal does not contact the spacer ring. So the next ones I will try are the Timken seal PN7486S, which are single lip seals. So far, after about 20 takeoffs and landings the #472737 seals seem to be working fine, and there is far less dirt on the wheel nut and wheel, indicating less seepage of grease . Since the seal drag is higher than the felt-type dust shields, I LockTited the inner spacer ring to the axle with blue LockTite, and drilled a tiny hole in the outboard spacer and the wheel nut so that an "anti rotation" pin could be installed to prevent rotation of the outer spacer. I will continue to report as more time is put on the seal system. By the way, SkyGeek shows a price (no stock) for the Cleveland seal #154-13000 of $33.00. The Timken #472737 seal cost about $3.00 from Motion Incorporated.
If anyone has experience with rubber seals, I would appreciate your thoughts.
