Anyone injecting Isoflex into the PTO port? Have a pretty fresh motor, just broken in and worry about the bearing. I heard some people inject 10-15cc isoflex into the port every season for maintenance and peace of mind. Bearing was packed with isoflex when rebuilt. I heard some say the grease stays in the bearing when looking during a teardown, other say little grease was left, so seems to be both ways. Any thoughts?
