22) Install new mechanical seal (76) into seal housing (91), and

press in lip seal (13).

23) Install mating ring (76) onto drive shaft.
24) Install assembled seal housing.
25) Install free end cover (7) following the same procedure used to

install the gear cover.

26) Apply sealer and install both port fittings (38 or 48).
27) Install all necessary cooling water lines.
28) Prior to putting booster into operation, follow Installation and

Operation instructions. Observe the oil level frequently during
the initial hours of operation. A badly installed or damaged oil
seal will result in oil loss.

Problem

Possible Cause

Solutions

Knocking or rapping

Unit out of time from worn
bearings or gears

Rotors making contact from
excessive temperature

Replace worn parts

Reduce temperatures by lowering
differential pressure

Excessive operating
temperatures

Pressure differential too high Reduce pressure across booster by

lowering cut in pressure

Check blank-off pressure of
forepump, and system for leaks

Lack of volume

Worn clearances

Reduced speed

Reestablish clearance

Check motor

Abnormal bearing and
gear wear

Inadequate lubrication

Maintain correct oil levels.
Improve oil change frequencies
Initiate oil sampling program

Loss of oil

Worn seals

Replace seals
