ESL Intensifier
Inspect the parts
11. Inspect the low-pressure hydraulic cylinder, end
bells, and related parts.
12. Remove the snap ring, spacer, and seal from the end
bell, but do not use a sharp tool—it will damage the
parts. Remove the o-ring and back up ring from the
end bell.
Repeat step for the other end bell.
13. Clean and inspect the end bells, seal spacers, and
snap rings.
Check the end bells for damaged threads,
•
damaged or out-of-round shift pin hole, and
damage to the sealing surfaces and grooves.
Seal spacers must not be warped or nicked.
•
Snap rings must not be bent and must have
•
the appropriate tension.
14. Apply clean hydraulic oil or Parker Super O-Ring
Lube (200006) to a new oil seal and install it in an
end bell with the spring insert visible. Place the
spacer on top of the seal and install the snap ring.

15. Lay the end bell flat. Apply clean hydraulic oil or
Parker Super O-Ring Lube to the new backup ring.
Locate the molding marks and install the backup
ring with the molding marks facing the end bell.
Lubricate the new o-ring and place it in the groove
on top of the backup ring. The o-ring must be out-
side the backup ring, facing the low-pressure
cylinder.
Repeat Steps 14 and 15 for the other end bell,
•
then set the end bells aside and cover with a
lint-free cloth.

Questions and answers
the red lights on side of sensors when pump is off only bottom two are illuminated
The bottom two red lights on the Flow ESL Intensifier sensors are illuminated when the pump is off because the system is not pressurized, and no hydraulic movement is occurring. These lights likely indicate a default or standby state when the pump is not actively generating high-pressure water.
