MOTOR SERVICE
The servo motor is flanged mounted and secured with four socket head cap screws.
The motor removal has to be done in a sequence as described below.
1. The manual roll release handle has to be removed. The inner roll pin holds the
handle to the shaft. Once this is removed the handle should slide off the shaft.
2. The belt guard has to be removed. It is fastened with four 1/4-20 socket head cap
screws on the 100 & 200 servos and five 5/16-18 socket head capscrews on the 300B.
3. Remove the belt tension then remove the motor.
4. Install new motor and reassemble in reverse order of the previous instructions.
5. When reinstalling the belt, the tension on the belt should be 1/64” deflection per
inch distance between the center lines of the pulleys using 1.5 to 2 lbs. force to cause
the deflection. The best way is to tension the belt and try running the servo for a few
cycles. If you get a high vibration on the belt when the feed stops then you have to
readjust the belt tension. It will have to have more or less tension to stop the vibration
of the belt.
MANIFOLD ASSEMBLY
The manifold assembly was designed to give the customer easy access to the
components. The valve for the electric roll release and if supplied, the anti-backup
valve is mounted on the side of the feed. The air regulator and pressure gauge is
mounted on the input side of the feed. All can be easily replaced if needed.
ROLLER AND GEAR BOX ASSEMBLY
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
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.
