Back Plate Replacement for FZ70S & DZ70 Engines - YSG1044A from YS Engine  [YSG1044A]

Rear back plate for FZ70S and DZ70 engines

This back plate assembly functions as a like-for-like replacement for YS FZ70S and DZ70 RC glow engines. The write-up focuses on correct fit and the repair role of the part, not on delivering performance improvements, so it is aimed at hobbyists carrying out engine servicing or overhauls.

Compatibility is specified to the FZ70S and DZ70 engine codes named by the manufacturer; always verify the code on your engine prior to purchase. Standard installation sequences include removing the engine from its mount, opening the rear housing to access the original back plate, and transferring internal parts into the new assembly. Normal hand tools and standard bench practices are adequate for these steps.

Use this component when returning a YS FZ70S or DZ70 engine to serviceable condition or when replacing a degraded rear housing element during routine maintenance.
