Product Overview
The 87307839 cleaning fan sheave bushing is a high-compatibility aftermarket replacement part specifically engineered for Case-IH combine harvesters. It serves as a direct substitute for OEM part numbers 87307839 and 194665C1, among others. Designed with reliability and ease of installation in mind, this Case-IH fan sheave bushing replacement helps restore full functionality to your machine’s fan drive system without the premium price tag of genuine parts.
Role of the Cleaning Fan Sheave Bushing
Positioned between the fan pulley and the drive shaft, the cleaning fan sheave bushing ensures a secure, slip-free connection that transmits power efficiently while minimizing vibration and friction. During harvest, the combine operates in harsh, dusty conditions—making this small component vital for consistent airflow through the cleaning system. A worn or damaged bushing can lead to belt slippage, unusual noises, reduced fan speed, or even premature belt failure. Keeping this Case-IH replacement bushing in good condition directly supports overall machine uptime and cleaning performance.
Application Scenario: Real-World Use of the 87307839 Cleaning Fan Sheave Bushing Replacement
During the hectic harvest season with your Case-IH combine, the cleaning fan sits at the heart of the entire sieving system. It generates a steady, powerful airflow to blow away lightweight chaff and straw fragments from the plump kernels. If the fan drive starts acting up, that airflow turns erratic, and suddenly your grain quality takes a hit.
Picture this: You’re out in the wheat field, and you notice too much chaff mixing back into the grain coming off the sieves—or worse, good kernels getting blasted out as waste. On top of that, there’s a persistent “buzzing” noise from the fan area, and the drive belt is whipping around or wearing down fast. Nine times out of ten, the culprit is the sheave bushing in the fan drive. Working in dusty, vibrating conditions day after day has worn it out, creating unwanted play between the sheave and shaft. That tiny gap throws the whole cleaning setup off balance.
Swapping in our 87307839 replacement bushing fixes things right away, delivering a few key benefits on the spot.
It restores steady airflow: The new bushing eliminates any wobble in the fan sheave, letting it spin at the intended speed without a hitch. You’ll get uniform airflow back, separating grain from debris like it should. The result? Cleaner output in the tank, with far less wasted crop.
It quiets the noise and cuts vibration: A snug-fit bushing stops the rattling and belt flutter dead in its tracks. That means a smoother ride for you in the cab, plus it spares the belts and bearings from extra stress—no more chain-reaction breakdowns eating into your downtime.
It safeguards the whole drive train: Think of a solid bushing as the foundation holding everything together. It keeps power flowing smoothly from the engine to the fan, preventing overload on shafts, bearings, or belts. In the end, your fan system lasts longer with fewer headaches.
Bottom line: Popping in this part gets your combine seeing straight again—picking out every valuable kernel while running quieter, smoother, and more dependably through the field.
Advantages of This Aftermarket Replacement
Crafted from high-strength alloy steel, each 87307839 cleaning fan sheave bushing undergoes precision machining and heat treatment for enhanced durability.

Every unit passes rigorous quality checks—dimensional accuracy, fitment testing, and simulated load cycles—to meet or exceed real-world demands.
As a cost-effective Case-IH aftermarket part, it offers excellent value: full OEM compatibility, consistent availability, and significantly lower pricing than dealership counterparts. Ideal for operators managing tight maintenance budgets without sacrificing reliability.
How to Replace the Fan Sheave Bushing Properly
- Preparation: Shut down the combine, disconnect power, and clean debris around the fan pulley area.
- Removal: Carefully remove the old bushing. Inspect the shaft, keyway, and hub for damage—replace or repair if wear is evident.
- Installation: Clean the shaft thoroughly, apply a thin layer of high-quality grease, align the new 87307839 bushing with the keyway, and press it gently into place. Torque bolts evenly to spec.
- Testing: Rotate the fan by hand to check for smooth movement and no binding. Start the machine and monitor for abnormal vibration or noise during initial operation.
Pro Tip: Check bushing condition and reapply lubricant every 250–500 operating hours, depending on dust levels and workload.
Common Issues and Quick Fixes
Look out for these warning signs:
- Excessive fan pulley wobble
- Squealing or grinding noises
- Accelerated belt wear
- Noticeable play between hub and shaft
These symptoms usually stem from bushing wear due to prolonged load, poor lubrication, or dust ingress. Installing a fresh cleaning fan sheave bushing replacement restores smooth power transfer, reduces system stress, and helps avoid costly downtime. If slippage or noise persists after replacement, inspect the belt tension, pulley alignment, and shaft condition.
