LUBRICATION
The Dodge Quantis MSM Gear Reducer is factory filled with ISO
220 EP type mineral oil to the correct oil level for the specified
mounting position. Changes in the mounting position will require
relocation of the oil level and vent plugs. Oil may have to be
added or drained to get to the correct oil level in the new mounting
position. See the Mounting Position Diagrams on Pages 4-9 for
the correct plug locations for various mounting positions of the
Quantis MSM unit. The oil level should be checked before startup
and frequently thereafter, preferably with the unit at operating
temperature.
The Dodge Quantis MSM gearbox is factory filled with lubricant.
The factory fill lubricant is suitable for use at all output speeds
and in ambient temperatures from +10°F to +105°F (-12°C to
+41°C). No initial oil change after break in is needed. The initial
factory oil fill is good for up to 10,000 hours or 3 years of service,
whichever comes first, in normal industrial environments.
Normal operating conditions are defined as steady loads not
exceeding normal ratings and running conditions as defined
in the Dodge Quantis MSM catalog. Oil quantity and levels
should be checked at frequent intervals, depending on usage.
Oil changes are required after 10000 operating hours, or three
years whichever comes first. The period can be extended to
20,000 operating hours, or six years, if a synthetic lubricant is
used. The lubricant should be changed more frequently if the
unit is operating in a hostile environment. For extremely hot, wet,
or dirty conditions consult Application Engineering at +1 864
284 5700. In those mountings that require grease lubrication for
specific bearings, relubricate the affected bearings every year
or every 2,000 operating hours, whichever comes first. Use a
grease with a lithium complex thickener and ISO 220 viscosity
mineral oil base lubricant. Use 15 pumps of grease for the first re-
greasing and 5 pumps of grease for subsequent re-greasing.
Dodge Quantis MSM Reducers are shipped with filling, oil level
and drain plugs in place. A separate breather is included with
the unit. Before putting the unit into service the filling plug must
be replaced with the breather. MW38 (2- and 3-stage gear units)
have one oil plug, ventilation is not necessary.
Approximate oil volumes for each Quantis MSM unit are listed
in the following tables in pints and liters. The oil volumes are
approximate and should not be used to determine correct
oil level. The correct oil level is defined as the bottom of the
appropriate oil level hole.
NOTE: Do not mix oils from different manufacturers. If a
change to another type or brand of oil is made, the existing
lubricant should be drained and the gearcase flushed with
a small quantity of the new lubricant before refilling with
the new lubricant. This is necessary to avoid possible
incompatibility problems between the two lubricants.
The list below gives approved alternative lubricants. This
is not an exclusive list. Equivalent lubricants from other
manufacturers may be used.
All reducers are factory filled according to the mounting position
indicated on the order. If the mounting position is changed from
the ordered mounting position, the oil level must be changed.
The oil volumes shown in the mounting position charts are
approximate. The correct oil level is determined by the oil level
hole in the housing except for size 38 reducers. If the reducer is
ordered with the standard mineral oil and the oil is later changed
to synthetic oil, it is recommended the shaft seals be changed to
Viton (FKM) material.
MSM is furnished with oil level, drain, and fill plugs except for the
size 38, which only has a fill plug. Before starting operation, the
breather must be located in the correct location.
Continued operation in cold ambient conditions requires special
modifications. Contact Dodge Industrial Inc. Gearing Application
Engineering, Simpsonville, SC for application assistance at +1

The density of the standard factory fill oil is 0.93 lbs/pint (1.98 lbs/
liter).
