Troubleshooting guide

The clutch-brake unit is designed with the bearing parts made from sintered metal that has been

impregnated with oil and normally do not need to be re-lubricated. In cases where there is severe

duty, the unit may be re-oiled or flushed out with minimal or no disassembly by using a light bearing

oil as used in manufacture (Shell Bearing Infusion Oil #33). If disassembly of the unit for cleaning

and oiling is necessary, follow the detailed disassembly instructions to the point needed, flush and

wipe parts in the oil to be used for re-lubrication. DO NOT USE SOLVENT to clean the parts. To

get more cleaning action for the oil, it may be heated while cleaning the components, but bring the

parts back to ambient temperature submerged in cool oil.

Lubrication

Place the Spring onto the Plunger with the narrow end towards the Actuator. Slide the Solenoid onto

the Actuator and Plate Assembly. Assemble the Solenoid to the Plate Assembly with the cap screws

and washers. DO NOT tighten more than finger tight.

Energize the Coil and adjust the gap between the Actuator and the top of the Collar Stop to 0.015"

to 0.030" by sliding the Solenoid assembly. Note: push the Collar toward the Actuator to allow for

Collar movement. Tighten the cap screws.

The stopping position of the head can be

changed if necessary by adjusting the position of

the stop cam on the control collar sleeve. Turn the

machine manually until the driver is in the desired

stopping position, the proceed as follows:

Work Retaining Ring "A" out of its groove and

slide it forward on Sleeve "C". Slide Cain "B" off

Splines, rotate to align Collar Stop with Actuator

and slide the Cam back on the Splines. The

Actuator Prawl will have to be held clear during

this operation. Slide the Retaining Ring back into

its groove.

Note: Make sure brake is locked up before

proceeding to insure getting the proper stop point.
