Perfect Shaft Fit in Minutes!

“Perfect fit and exactly what was needed to adapt an older pulley to a new engine. Installation was quick and made the upgrade fast, clean, and hassle-free.” – Kyle Ferome
Why Get Our Crankshaft Sleeve Adapter for Gas Engine Pulley?
✅ Fast Shaft Size Conversion: Engine upgrades often stall when pulley or clutch bores do not match the new crankshaft diameter. This sleeve adapter converts a 1 inch crankshaft to a 1-1/8 inch outer diameter, allowing compatibility with a wide range of pulleys, clutches, sprockets, and gearboxes. It supports engine swaps, belt speed changes, and clutch reuse without altering existing components.

✅ Precision CNC Machined Fit: The adapter is CNC machined to precise tolerances for consistent concentric alignment and smooth power transfer. A 1/4 inch integrated keyway ensures secure torque transmission, reduces vibration, and maintains stability during continuous operation. Designed for gas engine crankshafts used in lawn equipment, go-karts, utility machines, and select snow plow applications.

✅ Durable Stainless Steel Construction: Constructed from stainless steel 304 for superior strength and corrosion resistance in outdoor and high-moisture environments. The hardened, rust-resistant material protects crankshaft surfaces from wear, deformation, and galling while extending the service life of both the engine shaft and drive components.

📓FREQUENTLY ASKED QUESTIONS
Q: Which engines and equipment is this compatible with?
