Section
III
— Lubrication
INTRODUCTION
Carefully follow instructions on the drive nameplate,
warning tags and installation manuals furnished with the
drive. Failure to follow instructions will void warranty.
Lubricants listed in this manual are typical products
ONLY and should not be construed as exclusive
recommendations. Industrial type extreme pressure (EP)
or industrial type micropitting resistant gear lubricants are
the required gear lubricants. They can be formulated using
petroleum or synthetic base stocks.
Summary of allowable lubricant types by unit size can be
found in Table 1
The section on food grade lubricants provides guidance
in selecting lubricants for applications needing this class
of lubricants. Food grade lubricants are formulated using
petroleum or different types of synthetic base stocks.
WARNING : Failure to use extreme pressure or micropitting
resistant type lubricants in Planetgear Neptune, Neptune
Plus, Orion Plus, Saturn Plus, & Titan Plus size units will
void warranty.

LUBRICANT SELECTION PROCESS
1. Refer to Tables 4 and 5 for proper lubricant viscosity
grade based on ambient temperature range.
2. Refer to Table 2 for summary of lubricant type.
3. Using proper lubricant table and viscosity grade, select
desired lubricant manufacturer and name.
4. Refer to Table 3 for approximate oil capacity to
purchase
VISCOSITY (IMPORTANT)
The proper viscosity grade for petroleum-based lubricants
is found in Table 4. For synthetic lubricant viscosity grades,
refer to Table 5 and the “Synthetic Lubricants” paragraphs.
Viscosity grade is determined by ambient air temperature
in the immediate vicinity of the gear drive. Lubricant
selections must have a pour point at least 10°F
(5.5°C) below the expected minimum ambient starting
temperature.

LUBRICANT TYPES
PETROLEUM-BASED LUBRICANTS (TABLES 6A &
6B) – Industrial type petroleum-based extreme pressure
(EP) lubricants are common and readily available general
purpose gear lubricants.
SYNTHETIC-BASED LUBRICANTS (TABLES 7A & 7B) —
Synthetic lubricants of the polyalphaolefin (PAO) type are
recommended for cold climate operation, high temperature
applications, extended temperature range (all season)
operation and/or extended lubricant change intervals. The
proper viscosity grade of lubricants is given in Table 5.
Usable temperature ranges can sometimes be widened if
specific application conditions are known.
WARNING : Polyalkylene glycol (PAG) based synthetic
lubricants cannot be used in Planetgear units.
EXTREME PRESSURE (EP) LUBRICANTS (TABLES 6A
& 7A) — EP lubricants are manufactures from petroleum or
synthetic base lubricants. Anti-scuff is another term used
to describe EP lubricants.
MICROPITTING RESISTANT LUBRICANTS (Tables 6B
& 7B) — Micropitting resistant lubricants are specially
developed for surface hardened earing commonly used
in modern industrial gear drives. These lubricants contain
additives to resist formation of micropitting and other
conventional forms of gear wear.
WARNING: LUBRICANTS IN FOOD PROCESSING
INDUSTRY — Generally, conventional gear lubricants are
classified as H2 by NSF (National Sanitation Foundation)
since they contain harmful substances and should not
be used in the food processing industry. Lubricants
registered as H1 by NSF are suitable for food processing
applications.
CLIMATE CONDITIONS — Ambient temperature in
immediate vicinity of gear drive is very important for
determining viscosity grade. Table 4 provides viscosity
grade selections for petroleum-based lubricants. See
Table 5 for synthetic lubricants.
