Blue Line GY6 Short Case CVT Engine Cover Gasket

Description

Stop gear oil leaks and protect your drivetrain with the Blue Line GY6 Short-Case Transmission Cover Gasket. Precision die-cut from oil-resistant sealing material, this OEM-equivalent gasket spans the final drive gearbox cover interface on short-case GY6 125cc, 150cc, and 169cc 4-stroke engines. An 8-hole mounting pattern aligned to factory casing tolerances ensures a flush, airtight seal that holds up to thermal expansion, mechanical shear, and modern synthetic gear oils.

Key Features

• Oil-Resistant Material: Formulated to resist degradation from gear oils, high operating temperatures, and road grit.
• Precision Die-Cut: 8-hole pattern matches factory casing tolerances exactly — no binding or tearing during assembly.
• Even Compression: Compresses uniformly under standard torque specs to seal minor surface imperfections on cast aluminum engine halves.
• OEM-Equivalent Fit: Direct drop-in replacement when factory parts are unavailable or during a full rebuild.

Technical Specifications

• Overall Length: 410mm (16.15″)
• Mounting Holes: 8
• Engine Type: 4-stroke GY6 air-cooled, short-case (10″ rear wheel)
• Position: Left crankcase / final drive cover interface
• SKU: 1100-1136

Compatibility

Fits short-case GY6 engines only (10-inch rear wheel platforms). Will not fit long-case engines (12–13-inch wheel setups). Always measure your transmission cover length before ordering.

Installation Tips

• Clean both mating aluminum surfaces completely — remove all old gasket material, silicone sealant, and oily film. Use a plastic scraper to avoid gouging the soft aluminum.
• Tighten gearbox casing bolts in a crisscross star pattern to factory inch-pound specs for uniform gasket compression.
