H.5 SPECIAL TESTING INSTRUCTIONS
After pump has been reassembled with major kit, it is recommended that a break-in
test be performed to allow idlers to polish into babbitt housing bores. For test, pump
should be run to maximum required working pressure starting from 300 psig (20.7
Barg), in 200 psig (13.8 Barg) increments, holding each pressure five minutes.
