LUBRICATION
IMPORTANT: Because reducer is shipped without oil, it is 
necessary to add the proper amount of oil before running. 
Use a high-grade petroleum base rust and oxidation 
inhibited (R&O) gear oil - see tables. Follow instructions 
on reducer warning tags, and in the installation manual. 
Under average industrial operating conditions, the 
lubricant should be changed every 2500 hours of 
operating or every 6 months, whichever occurs first. Drain 
reducer and flush with kerosene, clean magnetic drain 
plug and refill to proper level with new lubricant. 
CAUTION: Extreme pressure (EP) lubricants are not 
recommended for average operating conditions. Failure to 
observe these precautions could result in bodily injury. 
CAUTION: Too much oil will cause overheating and too 
little will result in gear failure. Check oil level regularly. 
Failure to observe this precaution could result in bodily 
injury. 
Under extreme operating conditions, such as rapid rise 
and fall of temperature, dust, dirt, chemical particles, 
chemical fumes, or oil sump temperatures above 200°F, 
the oil should be changed every 1 to 3 months, depending 
on severity of conditions. 
CAUTION: Do not use EP oils containing slippery 
additives such as graphite or molybdenum disulfide in the 
reducer when backstop is used. These additives will 
destroy sprag action. 
Table 1 - Oil Volumes 
 
Consult DODGE for proper oil level for reducers with backstops and which are mounted in C-position or D-position.

 U.S. Measure: 1 quart = 32 fluid ounces = .94646 liters. 
Note: If reducer position is to vary from those shown in figure 1, 
either more or less oil may be required. Consult Dodge. 
If output is less than 15 RPM, consult Dodge. 
•  Below 15 RPM output speed, oil level must be adjusted to reach the 
highest oil level plug (P.).

Guidelines for TORQUE-ARM™ Reducer Long-Term 
Storage 
During periods of long storage, or when waiting for 
delivery or installation of other equipment, special care 
should be taken to protect a gear reducer to have it ready 
to be in the best condition when placed into service. 
By taking special precautions, problems such as seal 
leakage and reducer failure due to lack of lubrication, 
improper lubrication quantity, or contamination can be 
avoided. The following precautions will protect gear 
reducers during periods of extended storage: 
Preparation 
1. Drain the oil from the unit. Add a vapor phase corrosion 
inhibiting oil (VCI-105 oil by Daubert Chemical Co.) in 
accordance with Table 3. 
2. Seal the unit airtight. Replace the vent plug with a 
standard pipe plug and wire the vent to the unit.
