Maintenance
Coupling Element Replacement
The coupling element is designed to last for the life of the scroll
pump. If replacement does become necessary, remove the coupling
guard to gain access to the coupling rubber element (4). The photo
below shows the coupling guard separated from the assembly.
Before performing service, lock out and tag any
electric power source. Vent all air pressure from
the system and lock out and tag any other air sources.
Do not loosen the hexagon screws that secure the
motor adapter plate to the faceplate.
1. Loosen the screws that secure the coupling rubber element
radially to the drive hubs.
2.
DO NOT LOOSEN THE SETSCREW THAT SECURES THE DRIVE
HUB TO THE MOTOR SHAFT.
Do not use liquid thread lockers or adhesives. Do
not allow the element to become twisted while
tightening.
3.
Loosen the hex head screws that hold motor adapter plate 1
to motor adapter plate 2 (see image below). The motor must
be supported during this process to prevent damaging the
assembly. Pull the motor straight back to disengage.
6. Insert the Powerex supplied screws with pre-applied Inbus Plus
thread locker into the coupling element holes and tighten the
element securing screws to 37 ft-lbs.
4.
Now the axial bolts securing the rubber coupling element to
the compressor drive hub can be removed. Do not remove
or reposition the drive hubs.
Do not move or reposition the
motor mounting plate.
Installation is the reverse of removal.
Tightening torque for the bolts that secure the rubber coupling
element to the hubs is 37 ft-lbs.
5.
To install coupling insert, lightly lubricate the body and
underside of the element securing bolts with light oil or a clean
grease.
Do not lose the 4 alignment pins installed in the
two motor adapter plates. These pins are required
to maintain alignment between the motor and the pump.
