Ron you can get fresh seals through a bearing house or auto/truck parts outlet.
SKF/Chicago Rawhide 6119 (or 6120) or National/Timken 253747 for the PTO side.
Timken/National 471551 for the FW side.
Those numbers are for the seals that work with most 10-series, including these 82cc versions. The PM10-10S and a few others take a different FW side seal.
Thanks, Aaron. You got any interchange numbers for the bearings? Ron
