Assembly

When assembling parts, refer to the Illustrations and
Parts Lists for correct orientation and placement of parts.
Clean all parts with solvent and then dry thoroughly. Do
not expose O-rings or other packing components to
solvent for long periods of time.
Inspect all parts as they are assembled for signs of
damage, wear, cracks, etc. Do not install any parts
which appear to be damaged.
Apply hydraulic fluid or O-ring lubricant to all O-rings and
all metal surfaces which O-rings must slide over. When
installing an O-ring over a sharp edge, use a rolling
action to avoid damage to the O-ring.
Wherever assembled parts cause metal-to-metal
contact, coat the surfaces with hydraulic fluid or O-ring
lubricant.
