Back Plate Assembly for DZ140

This YS Engine back plate assembly is an RC-scale spare part intended for DZ140 engine series maintenance and repairs. It provides the structural rear cover that interfaces with the engine case and related internal components, and is supplied as a ready-to-fit replacement part bearing the manufacturer model number YSF2128A.

As a direct spare, the assembly's role is to restore the rear sealing surface and mounting points on the engine, helping to maintain proper alignment for muffler outlets and drive interfaces. When replacing the back plate assembly on a DZ140 engine, inspect mating surfaces, gaskets, and any seals for wear before installation, and verify that alignment and clearances match the original part to avoid stress on the crankshaft and bearings.

Installation is a routine service task on RC models using the DZ140 engine family; follow the engine manufacturer's service steps for disassembly and reassembly, hand-tighten fasteners to seat components, then apply the specified torque values from the engine manual. After fitment, perform a bench check of rotation and verify there are no binding points before returning the engine to the model.

This back plate assembly is supplied as an OEM spare part for routine service and repair of DZ140 RC engines, offering a direct replacement path to restore rear-case integrity and mounting features.
