CLEANING AND INSPECTION CONTINUED
CAUTION
Listed below are instructions that must be followed to insure correct assembly and
effective sealing of O-rings. Failure to follow these instructions may result in damage to
equipment.
Seal counter bores must be thoroughly cleaned.
O-rings, plungers, and counter bores must be lubricated with clean oil (WP 0018) on
assembly.
O-rings must be free of molding defects and handling damage.
O-RINGS MUST NOT BE STRETCHED beyond yield point. (Wrap a stiff paper around
plunger to protect O-ring passing over sharp machined edges.)
EXTREME care must be taken to avoid "ROLLING" O-ring into counter bore. (A twisted
O-ring is not likely to straighten itself after installation, and is almost certain to leak.)
Care in handling of parts and hydraulic system cleanliness cannot be over stressed.
Use ONLY oil type and viscosity ranges specified (WP 0018).
