ZENA™ Power Generator Testing (all models) Belt Drive Proper belt drive efficiency is key to insuring long term trouble free generator operation. This is achieved by having three things in balance -- drive pulley size, drive pulley belt wrap, and proper belt tension. Not too loose and definitely not too tight. If things are in balance, belt tension will be correct and the belt will not slip. - Page 6 typically an indication that grease, or some similar material may have caused “fouling” or glazing of the brushes and/or internal slip-rings. Cleaning can be accomplished in the field, if necessary , but is best done under factory (dust free) conditions. Disconnect the generator’s output terminal from any load, and check in the electrical resistance between each of the terminals and the case of the Power Generator.

the generator to its normal operating speed to allow the cooling fan to remove most excess moisture from inside the case.

Then, using a properly sized, unworn, Allen wrench, loosen first one pair of opposing bolts – then the second pair. When all four bolts have all been loosened, remove all four bolts from the case and set them aside. Locate the point where the front case and the iron lamination of the stator assembly meet. With a small screwdriver, working around the case perimeter, gently pry the front case assembly away from the stator assembly. -

Step Four – Reassembly Place the rear generator case on the bench top – orienting the generator case so that the rotor assembly can be gently lowered into the case until the end of the rotor shaft enters the rear needle bearing. At this time take particular care that the output terminals are positioned, in relation to the generator mounting foot and tensioning tab so as to meet the needs of your particular installation. -
