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.
3. Remove the belt tension and then the belt sheave has to be removed. To
accomplish this, rotate the sheave until the large end of the tapered shaft is to the
bottom. A support then has to be put under the center of the sheave to stop any
deflection of the motor shaft when driving out the tapered pin that holds the sheave to
the motor shaft. Drive out the pin and remove the sheave and then the motor.
4. Install new motor and reassemble in reverse order of the previous instructions.
Note: Use the sheave support when reassembling the tapered pin.
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.
MANIFOLD ASSEMBLY
The manifold assembly was designed to give the customer easy access to the
components. The valve for the electric roll clamp and if supplied, the anti-backup valve
are 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.
