PUMP HOUSING ASSEMBLY
Before assembly, make sure to clean the surface of all parts.
Assembly can be done reverse way against the disassembling procedure.
After replacing the old seals with new seals, put the
shims into shaft.
Assemble a rotor onto shafts. Make sure seal side first
into the shaft.
Tighten the first rotor bolt with a special tool to the
recommended torque. To tighten the second rotor place
the plastic dowel on the opposite side of the rotor and
tighten the second rotor bolt to the proper torque.
.
Excessive torque could make rotor bolts damaged or its
surface produced bur. If a bur is raised, it should be
removed by sander paper smoothly.
Install the cover and tighten the front cover bolts.
Use feeler gauges and depth micrometer to verify the back and redial clearances
between the rotors and the housing. A depth gauge should be used to verify the
front clearance
