Expert Maintenance Review
The bubble up auger gearbox is a critical wear point that facilitates the vertical lift of grain into the tank. Over time, internal gears and seals suffer from constant abrasion and heat-fatigue, leading to oil leaks and ultimate tooth failure. We recommend inspecting the gearbox oil levels and checking for input shaft play during every preventative maintenance check to identify worn components before they fail mid-harvest.
Upgrading to this high-performance gearbox set is a strategic choice to save money on major downtime. Replacing the complete set ensures both drive units are matched in wear and performance, keeping your grain handling system in top condition and providing a significantly longer service life for your loading circuit.
Installation Tip: Spline Lubrication
When installing the new 87721343 gearboxes, ensure the 19-spline auger shafts are thoroughly cleaned and coated with a high-pressure anti-seize lubricant. This prevents "fretting" corrosion between the shaft and the gearbox hub, ensuring a high-strength connection. This is the ideal time to check your bubble up auger flighting for wear to maintain maximum loading capacity.
