Bush Hog Seal Kit OEM #3677105

Restore factory-correct sealing performance and stop costly fluid leaks on your Bush Hog equipment with this Genuine OEM Seal Kit (Part #3677105). Precision-manufactured to exact Bush Hog factory specifications, this authentic seal kit provides all the correct factory-specified sealing components needed to rebuild and restore the sealing integrity of compatible Bush Hog hydraulic cylinders or gearbox assemblies — delivering the correct seal geometry, material compounds, and dimensional tolerances that aftermarket kits often cannot replicate.

Why Genuine OEM Seal Kits Matter:
Seal kits are among the most specification-sensitive replacement parts in agricultural equipment maintenance. Each seal in a hydraulic cylinder or gearbox assembly must be the correct cross-section profile, inside diameter, outside diameter, and durometer for its specific application. Rod seals, piston seals, wiper seals, and O-rings in the same cylinder can each be made from different rubber compounds — nitrile, polyurethane, or PTFE — optimized for different positions and functions within the assembly. An incorrect seal compound, cross-section, or size leads to immediate or accelerated seal failure, fluid leakage, cylinder bypass, or gearbox contamination. The genuine Bush Hog OEM seal kit contains all components pre-selected to the factory specification for their specific application — eliminating the risk of misidentification or incorrect material substitution.

What a Seal Kit Typically Contains:
Bush Hog hydraulic cylinder seal kits typically include the rod seal (wiper and main rod seal), piston seal assembly, O-rings for end caps and ports, and backup rings where required. Gearbox seal kits typically include the input shaft oil seal, output shaft oil seal, and related gaskets or O-rings. The complete OEM kit ensures every sealing point in the assembly is addressed in a single service operation.

Signs Your Seal Kit Is Needed:

• Hydraulic fluid leaking from the cylinder rod end — worn or damaged rod seal
• Cylinder drifting or failing to hold position under load — worn piston seal allowing internal bypass
• Hydraulic fluid or gear oil leaking from gearbox input or output shaft seals
• Hydraulic cylinder moving slowly or spongy despite correct fluid level and pressure
• Contamination (dirt, water, crop residue) entering the cylinder or gearbox through a failed wiper or lip seal
• Routine scheduled maintenance — replace seals proactively at recommended service intervals
• Cylinder or gearbox being disassembled for any reason — always install fresh seals on reassembly

Key Features:

• Genuine Bush Hog OEM kit — not aftermarket or generic
• Factory-correct seal profiles, dimensions, and material compounds for the specific application
• Complete kit format — all sealing components for a thorough, one-operation rebuild
• Eliminates seal misidentification risk — every component is pre-selected to factory specification
• Restores cylinder holding performance and eliminates fluid leakage for full equipment productivity
• Durable seal materials engineered for agricultural hydraulic fluid, operating temperature ranges, and field pressure cycles

Compatibility:
This seal kit fits select Bush Hog equipment. Always confirm fitment using your Bush Hog equipment model and serial number — found on the equipment identification plate — and cross-reference against your unit’s parts manual to verify this is the correct seal kit for your specific cylinder assembly or gearbox model. Note the cylinder or gearbox part number stamped directly on the component housing when ordering seal kits — this is the most reliable way to identify the correct kit.
