Procedure
8.
Inspect the wear plate for evidence of extrusion,
or marks caused by overheating. Remove the wear
plate from the body assembly. (fig C4356) Replace
if necessary. Remove the load ring, pre-load ring
and seal ring. (fig C4357) Do not use tools with
sharp edges to remove the seals, as damage to the
housing may result. Dispose of any damaged seals.
9.
Remove the shaft seal in the body assembly (if
applicable). Place the flange on the work surface.
Using internal snap ring pliers, remove the snap ring.
Check the seal quality and remove it if necessary. To
remove, pry the bottom of the shaft seal and force it
out while rotating the flange to lift it out evenly. Do
not use the flange pilot to gain leverage as damage
may result. Use a plastic rod or wooden dowel as a
fulcrum. After removal, dispose of the damaged seal.
