5.3.3 Input PTO shaft - Bearing Ring Replacement
Plastic wear bearing rings are found inside the PTO assembly to give a replaceable wearing surface between
the metal PTO shaft and the outer plastic safety shield/cone. Due to the parts design aim, the wear rings inside
the PTO assembly will be required to be replaced over the working life of the PTO shaft to ensure that the
outer plastic safety shield/cone does not wear through and expose the rotating PTO shaft found inside.
