HYDRAULIC LIFT ASSEMBLY
Note: Visually inspect spool outside surfaces
for scratches. Deep scratches are
unacceptable and the spool needs to
be replaced. Scratches that are deep
enough to catch the fingernail are also
unacceptable, and the spool needs to be
replaced.
Before replacing the spool, clean and
inspect the inner bore for damage. Check
the condition of the o-rings, particularly
for metallic particles embedded in the o-
ring surface. Damage to o-ring grooves,
particularly on the sealing surface,
is unacceptable. In the event that an
unacceptable condition occurs, the valve
needs to be replaced (Fig. 378).
