The lubrication section illustrates and lists items of the M081 Asphalt Mixing Plant which require lubrication checks and
service. Detailed lubrication instructions are listed for each major assembly of the asphalt mixing plant.
Electric motors should never require re-lubrication, motors are pre-lubricated for life. Factory grease is Chevron
SRI, 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 be
replaced with a non-polyuria grease. Select a grease specified for electric motors (suggest Precision EMB or
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 be
used, (DOD-G-24508, and NLGI #2, may be sufficient).
Grease all sealed bearings sparingly to ensure seals are not damaged. If seal Is broken by
evidence of large grease leak, grease more often or replace.
Other bearings require a Lithium NLGI #2 grease; suggest Petro-Canada Precision EP-2 or a Lithium NLGL #2
grease that meets DOD-G-24508.
A general multipurpose grease can be used on pivot points, kingpin (only if required), and suspension instead of
Precision EP-2 if desired. Precision EP-2 (DOD-G-24508), is specified to reduce the number of lubricant products
required for maintenance.
For high temperature bearings (drum drive and trunnion) Precision EP-2 is still compatible, however military grease
DOD-G-24508 must be used instead of DOD-G-24508.
