Scooterworks USA, LLC
Description
This Scooterworks USA Crankcase Oil Seal is the high-quality, reliable fix for QMI and QMJ engine cases. Precision-engineered to maintain a tight vacuum and fluid seal, it ensures your oil stays where it belongs: inside your engine.
Technical Performance Features:
Nitrile Butadiene Rubber (NBR): High-grade synthetic rubber offers superior resistance to engine oil, heat, and friction.
Double-Lip Design: Features a secondary dust lip to prevent road grit from entering the seal and scoring the crankshaft.
Precision Sizing: Exact 20mm (ID) x 30mm (OD) x 5mm (Width) dimensions for a perfect press-fit without specialized machining.
Internal Tension Spring: Includes a garter spring to ensure consistent radial pressure on the shaft even as temperatures fluctuate.
