Rapid-Air SERVO FEED: 100C, 100D series - Manual (Page 21)


The servo motor is flanged mounted
and secured with four socket head cap
screws. The motor removal has to be
done in the sequence described below.
1) The exit side roll guard should
be removed. The reason for this
will become evident when
reassembly of the handle to the
shaft is being accomplished.
2) The motor release handle has to
be removed. The inner roll pin
holds the handle to the shaft. The
roll pin has to be driven out as it
is a very tight fit. Once this is
removed then the handle
should slide off the shaft.

3) The belt guard has to be removed.
It is fastened with four 1/4-20
socket head cap screws.
4) Remove the belt tension by
loosening the 2 motor bracket
screws and let the motor slide
down to the bottom of the slot in
the bracket. Remove the motor
belt and then the motor.
5) The new motor should already
have the belt sheeve installed,
so exchange the motors on the
mounting bracket.
6) Reassemble the unit in reverse
order of the previous instructions.
7) When reinstalling the belt, the
tension on the belt should be 1/64”
deflection per 1 inch distance be-
tween the center line of the pulleys
using 1.5 to 2 lbs. force to cause the
deflection. Tension the belt so that
there is no slack and then run the
servo feed for a few cycles. If you
get a high belt vibration which
causes the servo unit to hum loudly
when the unit is sitting idle after a
feed, then the tension will have to
be readjusted by either tightening or
loosening the belt. This operation
may have to be performed 2 to 3
times to get it right. Once the servo is
running satisfactorily, this operation
will not have to be performed again.
At this stage of disassembly, all field
maintenance components are
exposed and easily accessible.
No further field service should be
necessary on the roller and gear box
Roller And Gear Box Assembly
assembly unless the gear train is
suspected of a malfunction. The drive
rolls should be checked for erroneous
wear pattern while they are exposed
and cleaned before reassembly.
DAILY:
a) Wipe off feed rolls.
b) Clean any dirt from servo unit.
c) Clean any dirt from operators
keypad.
WEEKLY:
a) Check wear pattern of rolls.
MONTHLY:
a) Check oil level (100C).
b) Check cables for cuts or wear.
