Remove the basket from the spindle. The basket is held to the spindle with a locknut on the inside of the basket, and the shaft and basket are fitted together with a taper. The basket may be removed from the spindle by "jolting" it off of the spindle or, if the extractor has been in service for a long period of time, you may have to press the basket off of the spindle. Next, remove the pulley, loosen the packing nut, and remove the bearing housing assembly with its shaft and bearings, after which new rubbers may be installed and the extractor assembled in reverse order. When installing new rubbers, be sure to place the flat face of the rubbers so they face the flange on the bearing housing; this will ensure that the concave side of the rubbers is down on the lower rubber and up on the upper rubber.

Ensure the extractor is lubricated at all points recommended by the manufacturer. Also, use lubricants approved by the manufacturer. As for the frequency, lubricate every 30 days or as experience dictates.

Troubleshooting

In troubleshooting the extractor, you must be able to recognize common troubles and know the possible causes of the trouble. Obviously, a lot of time may often be saved if the cause is found before any corrective action is started. Table X of appendix II will be useful to you as a guide in finding the sources of troubles in Milnor extractors.

TUMBLER

The tumbler, also called the "drying tumbler," is the machine used in Navy laundries to remove moisture from materials. The efficient removal of moisture by the tumbler provides material that can be ironed properly. There are various brands of tumblers manufactured by such companies as Cissell and Huebsch.

The Huebsch Loadmaster model 42-inch tumbler is often used at Navy activities. This is a commercial type of tumbler with a drying capacity of 100 pounds (dry weight) of laundry per hour. A two-motor drive system provides independent fan and cylinder operation. A one-way cylinder rotation and a door safety switch are standard.
