METAL DEGREE WHEEL FOR 4-STROKE ENGINES

PRECISION TOOL FOR ENGINE ASSEMBLY AND CAM TIMING

The Degree Wheel for 4-Stroke Engines is a precision measuring tool designed to accurately perform engine timing and camshaft degreeing, allowing precise synchronization between the crankshaft, camshaft and valve train.

It is an essential instrument for engine builders, performance shops, racing teams and enthusiasts who demand reliable, repeatable results when assembling or tuning high-performance engines.

TWO KEY FEATURES THAT MAKE THE DIFFERENCE

1) LARGE DIAMETER = REDUCED READING ERROR

A larger diameter improves scale resolution: as the radius increases, small angular variations become easier to detect, significantly reducing reading error and allowing more accurate and repeatable measurements.

This makes the degree wheel ideal for precise cam timing and detailed valve event analysis.

2) CENTRAL HUB WITH LOCK NUT = SOLID AND ACCURATE MOUNTING

The degree wheel features a central hub with locking nut, designed to mount firmly and concentrically to the crankshaft.
Once fixed, the graduated disc rotates smoothly over the hub, preventing unwanted movement during setup.

This ensures consistent measurements and safer, more accurate engine timing.

The central hub can be machined internally to match the diameter of the crankshaft bolt used on each specific engine.

MAIN FUNCTION

  • Precise measurement of crankshaft rotation angles

  • Accurate reference for camshaft and valve timing

  • Monitoring of valve events (opening and closing points)

  • Essential tool for engine assembly, verification and fine tuning

MAIN FEATURES

  • Available in multiple diameters to suit different applications

  • High-visibility, easy-to-read graduated scale

  • Designed for 4-stroke engines

  • Allows precise work at Top Dead Center (TDC)

  • Robust, durable metal construction for workshop use

  • Suitable for street, performance, racing and Pro Touring engines

APPLICATIONS

  • 4-stroke engines

  • Stock and performance engines

  • Camshaft degreeing and timing verification

  • Engine assembly and rebuilds

  • Professional workshops, engine builders and DIY projects

BENEFITS

  • Improved accuracy during engine timing

  • Reduced assembly and setup errors

  • Repeatable and reliable timing configurations

  • Essential tool for professional-level engine work

TECHNICAL NOTE

For correct use, it is recommended to combine the degree wheel with a piston stop and a dial indicator, ensuring an accurate reference of the engine’s true Top Dead Center (TDC).
