a. Place square end of piston on bench and hold
down firmly. Pull on end of shoe with other
hand and note end play. A good piston/shoe fit
will have no end play, but the shoe may rotate
and pivot on the piston ball. Inspect each shoe
face for nicks or scratches.
b. Measure shoe thickness (the part held between
retainer (27, Figure 6-14) and cradle. All shoes
must be equal within 0.0001 in. (0.003 mm). If
one or more piston/shoe assemblies (13)
needs to be replaced, all piston/shoes assem-
blies must be replaced.
c. Inspect cylinder bearing (26) and matching
cylinder barrel bearing mating surface for gall-
ing, pitting or roughness. Replace if necessary.
