Maintenance
Dodge Gear Reducer
Use the information that is on the gear reducer nameplate, the warning tags and the Dodge instruction
manual that is included with the Chain Loop manual to determine specific maintenance instructions for the
gear reducer used on the system. When referring to the dodge manual, note that the reducer is mounted
in the “D” position on the Chain Loop.
NOTE: The gear reducer is shipped dry and must be filled to the proper level before use.
Use a high-grade petroleum base rust and oxidation inhibited SAE 90 weight gear oil for ambient
temperatures from 15°F to 125°F (-10°C to 52°C). Oils with an “EP” additive are not recommended for
average conditions (see the lubrication section of the dodge manual). Use the check oil plug for
determining the correct amount of oil; too much oil will cause overheating and too little will cause bearing
and gear failure. The approximate quantity of oil for each reducer size is:
The oil should be changed at the beginning of every harvesting season if the Chain Loop is used for
seasonal grain handling. It should be changed after 2500 hours of operation or every 6 months if used
under average industrial conditions. The oil should be changed more frequently if used under extreme
operating conditions such as large changes in ambient temperatures, dust, dirt, chemical particles,
chemical fumes or oil sump temperatures above 200°F.
Drain the reducer, clean the magnetic plug and flush with kerosene before refilling with new oil.
Drive Belts
Check to make sure that drive belts are tensioned and aligned properly. Use a straight edge to check the
alignment with the motor and reducer sheaves. Adjust all the motor tensioning rods equally to keep the
motor shaft parallel to the reducer shaft.
