CFMoto Oil Seal 40*55*8

OEM Part Number 30500-040800N

🔩 Oil Seal · Seal · 40×55×8 mm

OEM quality · Direct replacement · Prevents fluid leakage

This is a genuine OEM-spec CFMoto Oil Seal, part number 30500-040800N, size 40mm (ID) × 55mm (OD) × 8mm (Thickness). Oil seals are used on rotating shafts or reciprocating components (e.g., crankshaft, transmission input/output shafts, differentials) to retain lubricants and prevent the ingress of dirt, water, and other contaminants. This direct replacement part effectively prevents leaks and protects internal precision components. Fits various CFMoto UForce series UTV models.

This Oil Seal (30500-040800N) fits the following CFMoto UForce series UTV models:

• OEM OE Quality: Manufactured to original specifications, ensuring identical dimensions and material.
• Premium Rubber Material: Made from oil-resistant, heat-resistant, and age-resistant synthetic rubber (e.g., NBR, FKM) for long-term reliable sealing.
• Precision Metal Case: Features a precision-formed metal case for rigidity and dimensional stability during installation.
• Spring-Loaded Lip: The sealing lip typically includes a self-tightening spring to maintain consistent radial force against the shaft, even with minor wear or runout.
• Direct Replacement: Designed for a perfect fit in the bore and on the shaft – no modifications required.
• Prevents Leakage: Effectively retains engine oil, gear oil, or grease, protecting internal precision components.

🛑 The Importance of the Oil Seal

Though a small component, oil seals play a vital sealing role throughout the vehicle. They prevent lubricant leakage from the engine, transmission, differential, and wheel hubs, while blocking dirt, dust, and water from entering. A hardened, cracked, or damaged seal leads to fluid leaks, causing inadequate lubrication, accelerated wear of internal gears and bearings, and potential environmental contamination. In severe cases, fluid loss can lead to component seizure and failure. Regularly inspecting and promptly replacing leaking seals is essential maintenance to keep these critical assemblies healthy and prevent major breakdowns.
