The XRAY 338540 Flywheel Collar is made to fit Novarossi engines that use a 7mm collar, delivering a tight, accurate fit that stabilizes the crank assembly. Its precise machining helps reduce vibration and supports consistent engine running for both track and backyard use.
This 7mm collar from XRAY seats securely on the crank, minimising slop and helping to protect adjacent components from premature wear. It is a practical maintenance part for hobbyists wanting a simple, effective way to keep Novarossi engines running smoothly.
