Expert Maintenance Review
To keep your storage and unloading system in top condition, we recommend inspecting the shaft bkeys and shaft wear whenever these sprockets are replaced.
Because these sprockets drive critical clean grain and tailings elevators, using a precision-machined 1045 billet sprocket ensures a much longer service life compared to standard cast alternatives. Standard preventative maintenance suggests that replacing drive sprockets when installing new chains will significantly improve extended wear and prevent premature chain "climbing."
Recommended Maintenance Upgrade
To ensure maximum grain handling efficiency, we highly recommend inspecting your Elevator Chains and Head Bearings for wear whenever new drive sprockets are installed.
