Keep your CVT housing sealed and your drivetrain protected with this Universal Parts CVT Cover Gasket for 139QMB long case engines. Designed specifically for the larger "long case" 50cc and 80cc 4-stroke 139QMB engine platform, this gasket provides a precise, debris-free seal between the crankcase and transmission cover. Replace it every time you open the CVT for belt or variator service to prevent road grime, moisture, and dust from entering the housing and causing premature wear.
Key Features
- Long Case Fitment: 17-inch length matches the long case 139QMB engine found on scooters with 12" or 13" rear wheels.
- 10-Bolt Pattern: Accurately punched bolt holes align with factory mounting points for a wrinkle-free, uniform seal.
- Oil-Resistant Composite Material: Durable gasket paper compresses on installation to fill minor surface imperfections in the metal casing.
- Debris & Moisture Barrier: Seals out dust, water, and road salt to extend the life of your variator, rollers, and drive belt.
Technical Specifications
- Overall Length: 17 inches
- Widest Point: 7 inches
- Bolt Hole Count: 10
- Engine: 139QMB / 1P39QMB (Long Case only)
- Application: 50cc and 80cc 4-stroke scooters
Fits Long Case 139QMB-based engines (engine codes: 139QMB, 1P39QMB, 139QMA, YN139QMB, JJ1P39QMB, BD1P39QMB, BN139QMB among others).
If your CVT cover is approximately 17 inches long, this is the correct gasket. Compatible with a wide range of Chinese 50cc scooter brands including TaoTao, Roketa, Wolf, Bintelli, ZNEN, Jonway, Keeway, Vento, and many others using the 139QMB long case engine platform.
Mechanic's Note: This is for the Long Case 139QMB only (typically found on scooters with 12" wheels). If your CVT cover is approximately 16 inches long, you need the Short Case version.
Do not use RTV silicone on a CVT gasket — it makes future belt changes extremely difficult.
