HYDRAULIC COMPONENT REPLACEMENT
WARNING
!
Before removing any components as discussed in the following sections, trip the
impact valve, and remove power to the submersible pump for the product in question
to prevent fuel spillage. Failure to do so could cause a possible fire hazard that may
result in serious injury or death.
WARNING
!
Drain the fuel into an appropriate container and pour it into an underground tank to
prevent fuel drainage under and around the dispenser. Failure to do so could cause a
possible fire hazard that may result in serious injury or death.
7.2.1.
Diaphragm Replacement (Non-Blenders Only)
1. Remove the four (4) bolts and the diaphragm cover.
2. Remove the diaphragm and discard. The center section and cover will be
reused. Note of the position of the disc and spring as they are removed so
they can be installed the same way.
3. The spring must be seated squarely in the spring cup so that it will stay in
place when the valve cover is installed.
4. Hand tighten the four (4) bolts, using a crisscross pattern until the bolt heads
just contact the valve cover. Continue this pattern increasing torque until all
bolts are fastened to a torque of 9-11 ft. lbs. This torque must not be
exceeded in order to keep the gaskets from deforming and covering the
ports.
5. Check operation and inspect for leaks.
