DZ70 Upper Push Rod Replacement YSG7078 by YS Engine  [YSG7078]

Fit and function for DZ70 valve train

This upper push rod is an RC-scale spare crafted to match the DZ70 engine family identified by the YSG7078 model number. It operates as the linkage between rocker components and the valve train and is supplied for maintenance and replacement use rather than as a performance upgrade.

Installation notes: confirm correct orientation before securing, inspect the mating ends for wear, and ensure alignment with existing rocker arms and linkages to avoid binding. Use appropriately sized hardware and tighten to recommended torque for your model's valve train, checking movement through the full throw after fitment.

Service role: replace this component during routine valve train servicing and inspect adjacent items such as rocker pins and seals to maintain reliable engine timing and operation.
