YS Engine YSG7040 Push Rod DZ70 replacement pushrod for DZ70 RC engines  [YSG7040]

YS DZ70 push rod replacement

This is a replacement push rod intended for RC-scale YS DZ70 glow engines, supplied as a single service part to restore proper valve actuation. The component is described as a push rod for the DZ70 family and is intended to match the original function in the engine's valvetrain linkage.

Use this push rod when the original shows wear, bending, or excessive endplay that affects valve timing. It transfers cam or rocker motion to the valve lifter, so correct fit and straightness are important for reliable engine running and precise valve clearance during setup.

Installation is straightforward at a component level: remove the rocker/valve linkage retaining hardware, withdraw the old push rod and replace with the new unit, then reassemble and verify valve clearance and movement through the full travel range. After installing, check for smooth operation without binding and confirm clearances before running the engine.

Compatibility: For DZ70 series YS RC glow engines.
