TM 5-3895-374-10CHAPTER 3MAINTENANCE INSTRUCTIONSI.LUBRICATION INSTRUCTIONS3-1Lubrication InstructionsThe lubrication section illustrates and lists items of the M081 Asphalt Mixing Plant which require lubrication checks andservice. Detailed lubrication instructions are listed for each major assembly of the asphalt mixing plant.1.Electric motors should never require re-lubrication, motors are pre-lubricated for life. Factory grease is ChevronSRI, which is a polyuria grease that conforms to MIL-G-3545C. In the event that re-lubrication is necessary,(bearing replacement) the same grease, or compatible, should be used. Alternately, the existing grease could bereplaced with a non-polyuria grease. Select a grease specified for electric motors (suggest Precision EMB orequivalent).2.NTN ball bearings are sealed and greased for extended life with SHELL Alvania No. 3 by bearing manufacturer.In event that they do require re-lubrication Alvania No. 3 (or compatible Lithium based NLGI #3 grease) should beused, (DOD-G-24508, and NLGI #2, may be sufficient).NOTEGrease all sealed bearings sparingly to ensure seals are not damaged. If seal Is broken byevidence of large grease leak, grease more often or replace.3.Other bearings require a Lithium NLGI #2 grease; suggest Petro-Canada Precision EP-2 or a Lithium NLGL #2grease that meets DOD-G-24508.4.A general multipurpose grease can be used on pivot points, kingpin (only if required), and suspension instead ofPrecision EP-2 if desired. Precision EP-2 (DOD-G-24508), is specified to reduce the number of lubricant productsrequired for maintenance.5.For high temperature bearings (drum drive and trunnion) Precision EP-2 is still compatible, however military greaseDOD-G-24508 must be used instead of DOD-G-24508.page 3-1
