from the pump housing. Use the
following procedure to remove the end
plate:
• Use a stiff bladed putty knife to pry the
cover away from the housing until there
is a small gap all around.
31
• Once there is a big enough gap behind
the end plate, use two blunt tipped pry
bars or two flat head screw drivers,
placed opposite each other, to pry the
cover (and bearing) free of the rotor
shaft.
`
NOTICE : Be careful not to damage the
O-ring between the end plate and the
pump housing.
„
IMPORTANT : The rotor bearing will
usually remain pressed into the end plate
upon removal. Be careful when pulling the
bearing free of the rotor shaft that the rotor
does not fall down inside the pump
housing. It may be necessary to provide a
means of support for the rotor, such as a
block of wood under the rotor shaft.
5. Remove the rotor vanes, one at a time,
by first rotating the rotor so as to position
a vane at the bottom of the housing. With
the vane placed downward, there will be
enogh clearance around the rotor to
grasp the vane and slide it out the end of
the rotor slot.
6. After removing each vane, simply slide a
new vane (that has been dipped in oil)
into the rotor slot.
„
IMPORTANT : Always replace vanes
in sets.
7. Before reassembling, inspect the rotor
bore, bearings, seals, and gaskets, and
replace as necessary. Seals should be
soft and pliable, gaskets should not be
torn, and bearings should turn freely.
8. Reassemble the vacuum pump in the
reverse order of disassembly. Finally,
reassemble the vacuum pump and
coupling assembly back onto the slide-in
unit. Be sure to replace the coupling
guard after assembly.
WARNING : Keep all shields in
place. Shields and covers are designed
to protect the operator from
entanglement in moving parts, which
can lead to serious injury or death. DO
NOT remove shields from the unit
except when servicing; then, replace
immediately.
„
IMPORTANT : Be sure to use the
correct size sleeve (one that fits against
the inner race of the bearing) when
installing the bearing back onto the rotor
shaft. Use a soft mallet against the sleeve
to press fit the bearing onto the shaft.
