Royal Enfield Genuine Exhaust Cam Gear Assembly with Auto-Decompressor for UCE Models – Part No. 570309/D

Product Description

The Genuine Exhaust Cam Gear (570309/D) is a sophisticated internal engine component that manages the exhaust valve timing. This specific assembly features an integrated automatic decompression mechanism, which slightly lifts the exhaust valve during the compression stroke at low RPMs. This reduces the effort needed to turn the engine over, preventing “kick-back” and reducing strain on the starter motor and battery. Manufactured to rigid OEM standards, the gear is precision-machined to mesh perfectly with the timing gear train, ensuring quiet operation and long-term reliability.

Key Features:

• Integrated Auto-Decompressor: Essential for modern UCE engines to ensure easy starting and to protect the sprag clutch from damage during startup.

• High-Strength Steel Alloy: Crafted from hardened steel to resist tooth wear and ensure the decompressor pin/weight mechanism remains functional over thousands of cycles.

• Precision Timing Teeth: Engineered for a perfect fit to maintain exact exhaust valve opening and closing intervals, critical for engine performance.

• Noise Reduction: Balanced and polished gear surfaces minimize mechanical clatter within the timing chest.

• Genuine Factory Quality: 100% original Royal Enfield spare, ensuring the spring tension and weight of the decompressor are calibrated to factory specs.

• Authenticity Guaranteed: Packaged in official Royal Enfield branding with a security hologram and verified part number.
