ABOUT THIS MANUAL
MHP30RM1AE/9541AV (1 of 1)
Scope
—This instruction manual is intended to provide preventive maintenance procedures, service procedures, and mechanical parts identification for all Milnor® 30015, 30020, and 30022 model rigid mount
washer-extractors. Measurements are in commonly used US and metric units unless otherwise noted.
See the appropriate programming, operating, and troubleshooting manual for inform ation on the control
system. See the schematic manual for electrical parts identification and electrical troubleshooting.
Manual Number/Date Code (When To Discard or Save)
—The manual number/date code
is located on the inside front cover, upper right corner just above the manual name. Whenever the manual is
reprinted with new information, part of this number changes. If the date code after the “/” changes , the new
version applies to all machines covered by the old version, but is improved— thus the old version can
be discarded. If the manual number before the “/” changes, the new manual covers only new machines.
Example: Discard MATMODELAE/8739CV when MATMODELAE/8739DV is received (minor improvements). Also, discard MATMODELAE/87
V when MATMODELAE/87
39D
V is received (major im-
46A
provements). But keep MATMODELAE/8746FV when MATMODELBE/8815AV is received, since the
new manual no longer applies to machines originally shipped with the old manual.
Documents and Change Bars
—The individual documents comprising this manual use the same
revision criteria as the manual. Text documents also display change bars. Example: When section
MSOP0599AE/9135BV becomes MSOP0599AE/9135CV, change bars with the letter “C” appear next to all
changes for this revision. For a major rewrite (e.g., MSOP0599AE/92
For Assistance

ÈFASTENER TORQUE REQUIREMENTS
The specifications in this section apply to 1/4 inch and larger Unified National fine and coarse fasteners used on
Milnor® machines. This information is to be used only when torque specifications are not stated in the installation
or service instructions.
When tightening applicable fastener, abide by the follow-
ing precautions:
1. Always use new fasteners. Replace bolts, nuts, flat wash-
ers, and lock washers in the order shown on the parts
drawing.
2. Unless otherwise specified, use:
• Loctite® 271 threadlocker or equivalent for bearing
housing mounting bolts from one half to one inch in di-
ameter.
• Loctite® 277 threadlocker or equivalent for bearing
housing mounting bolts of one inch diameter or larger.
• Loctite® 242 threadlocker for all other fasteners
requiring thread locking compound.
3. Use a torque wrench to assure proper tightness.
4. Never lubricate fasteners. The values specified herein are
maximum recommended torques and are calculated from
published ASTM and SAE data. Actual allowable torques
are application dependent and can vary for many reasons,
(joint types, gaskets, etc.). Use these values as a guide.
5. Although FIGURE 1 depicts hex head bolts, the table applies to all head types.
ÎFIGURE 1
ÎFastener Grade Markings
(MSSM0101CE)
ÊFasteners and Threadlocker
ËHow Fasteners Loosen
bly. With the fastener at the proper torque, 85% of the tightening torque is absorbed in the threads and under the
fastener head. The remaining 15% provides t he fricti on t hat prevents the t hread from sl ippi ng. When thi s frict ion is
overcome (by bending, thermal expansion, internal pressures, functional loads, or impact) the thread slips and loosens. Although higher torques reduce the likelihood of thread slippage, if slippage occurs, the threads unwind and
the fastener loosens. Once thread slippage begins, vibration increases the rate of loosening.
ËPreventing Loosening
cation of a threadlocking compound. Threadlocker provides lubrication during assembly, then hardens to seal the
threads against corrosion and provide resistance to thread slippage.
—Standard threaded fasteners are manufactured with a clearance fit for easy assem-

MSSM0101CE/9906AV (2 of 19)
ÊApplying Threadlocker
NOTE: The following threadlocker information and
illustrations are excerpts from the Loctite® User’s
Guide and are used with permission.
For maximum strength, threadlocker must fill the thread
voids completely, as shown in FIGURE 2. Organic or petroleum solvent will remove excess uncured adhesive from
joints. Consult information below for the specific fastener application.
ËBolts and Nuts
—See FIGURE 3.
1. Clean all threads (bolt and nut) with cleaning solvent.
2. Spray all threads with Loctite® Primer N. Allow to dry.
3. Insert bolt into through hole assembly.
4. Apply several drops of threadlocker onto bolt engage-
ment area.
5. Assemble and tighten nut to correct torque for the
threadlocker.
ËBlind Holes
—See FIGURE 4.
1. Clean all threads (bolt and nut) with cleaning solvent.
2. Spray all threads with Loctite® Primer N. Allow to dry.
3. Squirt several drops down female threads into bottom of
hole.
4. Apply several drops to bolt.
