Ê C ylinder Speeds Machines covered by this section have four cylinder speeds. Slowest to fastest, these are wash, drain, low ex- tract speed (E1), and high extract speed (E2).
  • Page 44 Ë D rive Train Precautions Do not subject the drive train to stress by instantaneous transitions from stop or wash to extract speeds, nor from extract to wash speeds. To avoid damaging the mechanical components and hazardous conditions, the motors and clutches gradually accelerate and decelerate the cylinder. These gradual speed changes are inherent in all control systems and must not be bypassed through manual operation or programming modifications.
  • Page 45 SEVERE MACHINE DAMAGE—Severe machine damage can result if the low speed drive engages during or at the end of extract. Immediately lock OFF and tag out power at the wall disconnect if any of the following occur: The machine makes a sound like skidding automobile tires as it comes out of extract; The wash or drain clutch does not disengage or prematurely engages during extract;...

  • Page 61: Replacing Main Bearings And Seals On 30015

    Replacing the entire bearing housing assembly or a major bearing housing compo- nent requires removal of the shell. Maintenance procedures require: • Cylinder puller kit P/N PK33-008 (or equivalent) available from Milnor ® on a rental or purchase basis.
  • Page 62 Ê R eplacing Seals with Bearing Housing In Place NOTE: See the appropriate bearing assembly drawing. If no water or metal particles are present in drained oil, replace seals and o-rings as follows. If bearing oil contains water or metal particles, see “Replacing Bearings with Bearing Housing in Place” below. 1.
  • Page 63 Ë R emoving the Shell NOTE 1: 30015 front bearing housing bolts are provided with self-locking nuts. NOTE 2: 30020 and 30022 shell back clamp rings have three push-off holes to aid in removal. Replace the three plastic set screws with three bolts then tighten evenly to separate the ring from the shell.
  • Page 64 Grind off the alignment washers as shown in FIGURE 3 and discard old alignment washers. Î F IGURE 3 (MSSM0708BE) Î A lignment Washers 4. Grind the rear console smooth in preparation for 30015 Models (see Note 2 above) main bearing re-installation.
  • Page 65 NOTE 3: Install a new NYLTITE washer and nut gasket on each new shell bolt (see FIGURE 5). On 30015 Machines—Replace the four J-type nuts along the rim of the front console with new clips. 1. Determine that all threaded holes are clean and in good condi- tion by screwing a new bolt into each hole (if necessary, tap out any damaged threads).
  • Page 66 9. Tighten bolts. Insure there is approximately .0625 inch (1.6 mm) clearance between the alignment washers and the console as shown in FIGURE 7. Add or subtract shims as required to obtain the specified clearance. Weld the new alignment washers to the console. 10.
  • Page 67 Ê I nstalling the Cylinder and Shell Front 1. Screw two new allen screws into the cylinder puller mounting holes; do not obstruct the shaft retainer spacer seat. 2. Determine that the main shaft is clean and free from any foreign material and that the key is properly seated. Failure to properly install cylinder may cause it to loosen during machine operation.

  • Page 79 3. Thoroughly clean all parts with solvent. The bearing housing and shaft must be absolutely clean and free of dirt and ad- hesives. 4. Install a new inner retaining ring inside the housing and apply a small amount of retaining compound (Loctite 271 or similar) around the bearing seating surface of the bearing housing as shown in FIGURE 2.

Use a high quality digital voltmeter (Fluke model 77 or similar) for measuring voltages.
  • Page 93 ELECTROCUTION HAZARD—Machine power is ON and covers are removed for the following procedures. You can be killed or severely injured by contact with exposed components which are energized at 120VAC or higher. DO NOT touch any components while adjusting output voltage. See FIGURE 2 during the following procedures: 1.
  • Page 94 Ê F or MARK II Models Ë R eplacing the Power Supply The Mark II power supply mounts inside of the Mark II control box atop the machine. After replacing the power supply, see “Adjusting Output Voltage” in this section. ELECTROCUTION HAZARD—High voltage is present inside electric boxes, mo- tors, and many other components.
  • Page 95 2. Touch the positive meter probe to the rear of pin 3 (+5VDC). Voltage must be between 4.95 and 5.06VDC. If not, turn the 5VDC potentiome- ter slowly until the meter displays the correct value. The microprocessor will not oper- ate if this voltage is not within tolerance.
  • Page 98 MSFD0501BE/9273AV È A BOUT THE COIN COUNTER Ê D escription NOTE: Ensure that the machine is level for proper coin counter operation. The coin counter can be adjusted to count from 1 to 63 coins without tools or extra parts (for further informa- tion see “HOW TO SET REQUIRED NUMBER OF COINS”...
  • Page 99 Ê T roubleshooting If the coin reject solenoid buzzes when energized, dirt is preventing it from seating fully. If the coin counter mechanism is rejecting all coins, the solenoid should be replaced. The coin switch is factory adjusted and does not require field adjustment.

  • Page 102: Vibration Safety Switch

    When the machine leaves Milnor , the actuator arm is tie-wrapped to prevent damage (except on 30015, 30020, and 30022 models). This tie wrap must be removed after the machine is set into position but before the machine is op- erated.
  • Page 103 that it has reset. In the released position the arm should rest lightly but definitely against the stop on the micro-switch case that prevents any further arm movement to the left. For machines with rigid mounted shells, where the machine is bolted to a very substantial foundation, very little machine movement will occur for a given degree of out-of-balance.
