It creates a seal between the engine case and the transmission housing, helping keep dirt and moisture out of the drivetrain. As with many \u003ca href=\"\/collections\/gy6-50cc-parts\"\u003eGY6 50cc scooter parts\u003c\/a\u003e, it is best to swap in a new gasket any time the CVT cover is removed for service, since reusing an old one can let contaminants speed up wear.\u003c\/p\u003e\u003ch3\u003eLong Case Compatibility\u003c\/h3\u003e\u003cp\u003eAt 17 inches long, this gasket matches the long case version of the 139QMB engine, which is usually found on scooters with 12\" or 13\" rear wheels. The 10-bolt pattern is punched to line up with the factory mounting points, so it sits correctly and seals well when installed.\u003c\/p\u003e\u003ch3\u003eMaterial and Function\u003c\/h3\u003e\u003cp\u003eThe gasket is built from an oil-resistant composite. When the cover is tightened, the material compresses slightly to fill small irregularities on the mating surface, giving a snug fit. It works as a barrier against dust, moisture, and road debris, which helps protect the variator, rollers, and other transmission parts over time.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Oil-Resistant Composite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 17 inches length, 7 inches widest point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Hole Count:\u003c\/strong\u003e 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e 139QMB \/ 1P39QMB (Long Case only)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e 50cc and 80cc 4-stroke scooters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GY6 50cc and 80cc 4-stroke long case 139QMB engines (17-inch CVT cover, 10 bolts)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGY6 50cc 139QMB long case engines (scooters with 12\" or 13\" rear wheels)\u003c\/li\u003e\n\u003cli\u003eGY6 80cc 139QMB long case engines (4-stroke)\u003c\/li\u003e\n\u003cli\u003eTaoTao, Roketa, Wolf, Bintelli, ZNEN, Jonway, Keeway, Vento (139QMB long case engines)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHow to choose:\u003c\/strong\u003e Check your CVT cover.
