PISTON ROD ASSEMBLY
Check for scoring. Replace if the scoring can be felt with
the finger nail (Fig. 13.1).
Repair if the rod has light scoring. They can sometimes be
smoothed out with 220 grit or fine emery cloth.
Check for uneven rod wear. Replace if an uneven surface
is felt (make sure to inspect the whole rod surface,
sometimes the wear is located on a small area) (Fig. 13.2).

PISTONS
Replace if the surface where the O-Ring seats shows
wear (Fig. 14.1).
NOTE: Check the outside surface where the O-Ring and
backup are placed. Check surface for an O-Ring groove.
