Page 30 Ê G eneral Requirements Maintenance procedures require: • A hand operated grease gun. • The correct lubricants (see “LUBRICANTS FOR MILNOR MACHINES,” in the Table of Contents). Ê L ubricant Requirements ® To achieve the optimum performance and service life from the Milnor machine and as a warranty require- ment, the machine must be lubricated in strict accordance with the instructions in this section.
Page 31 CRUSH/SEVER HAZARD—Tilting machines with tilt wheels/cradles may lunge forward or rearward and even fall over if the tilt wheels at the non-tilted end are raised out of their cradles—killing/injuring personnel and/or damaging prop- erty. NEVER manually tilt (lift) both ends of the machine at the same time. One end must always be seated in its cradle.
Page 41 <BB<!&#04(&" 0E Most of the information in this document is taken from the Baldor Electric Company Instruction, Operation, and Maintenance Manual, and provides a means of more accurately determining motor lubrication requirements based on local conditions. Inspect, clean, and test motors at regular intervals— approximately every 500 operating hours or every three months, whichever comes first.

“short circuit” exhaust connection near the clutch. The quick release valve is necessary for the clutch used on ® Milnor washer-extractors, and is furnished as original equipment. The air supplied to the clutch must be free of oil and moisture.
Page 90 It is essential when removing the gear reducer, to record the positions of these shims so that they may be replaced in the exact same position later. Bearing this in mind, carefully remove the gear reducer mount- ing bracket (with the reducer attached) from the drive base. Note that the clutch tire, attached to the reducer output shaft, must be allowed to slip out of the clutch drum as the reducer is removed.
Page 91 3. Temporarily disconnect the internal air line to the gear reducer and connect an external, valve-controlled air line to the reducer, but do not inflate the tire yet. 4. Loosen but do not remove the bolts that attach the gear reducer mounting brackets to the drive base. (On 64" machine models, check to be sure the jacking bolts under the input shaft side of the reducer are resting on the drive base then loosen the bolts and remove the dowel pins if they were reinstalled.) 5.
Page 92 To replace the jackshaft, reassemble all components in reverse order of their removal. Make certain that the jackshaft is properly oriented with the clutch end of the shaft to the front of the machine and that all shims are returned to their original positions. Install all jackshaft mounting bolts hand tight. Lift each end of the jackshaft with a pry bar (one end at a time) then tighten the bolts on that end, so that the jackshaft will sit as high as possible in the housing.
Page 93 Ê C entrifugal Switch Ë C oncept of Operation —After an extraction, the centrifugal switch will signal the Miltrol as soon as the washer cylinder has slowed sufficiently to permit the wash speed clutch to re-engage. Also, until this low speed has been attained, the Miltrol circuits prevent the opening of the shell door, thus providing safety interlocking.

Page 118 Carrier), Seal Sleeve, and Seals (Front or Rear) ® These procedures require the use of a pulling fixture and guide rods available from the Milnor factory. With the bearing cover (or shaft seal holder) and the bearing removed, proceed as follows: 1.
Page 119 NOTE: Step 2a or 2b below will cause the bearing housing to slide away from the shell. Shims were placed under one or more of the three bearing housing pads during factory assembly to align the housing and insure its being exactly parallel with the shaft. When removing the bearing housing, be sure to keep these shims separate and identified so that they may be returned to their proper location, otherwise the bearing and seal will be out of line and may be damaged after a short operating period.
Page 120 Ê R eplacing the Bearing Housing, Seal Sleeve, and Seals (Front or Rear) 1. With the seal sleeve removed, press all old seals out of the bearing housing. Remove the large o-ring from the outside of the housing. Thoroughly clean the bearing housing and flush out all grease passages to make cer- tain they are unblocked.
Page 121 6. With two of the three temporary guide rods in position on the shell, place the bearing housing onto the guide rods and install the seal sleeve setting fixture on to the bearing housing as shown in FIGURE 7. The seal sleeve setting fixture prevents the seal sleeve from being pushed out of the housing as the housing is in- serted into the shell.
