YS Engine YSF2128A Replacement Back Plate for DZ140 Engines  [YSF2128A]

Rear Cover for DZ140 Engines

Designed for the DZ140 engine range, this YS Engine back plate assembly is a maintenance spare that reinstates the rear case cover and interfaces with the engine internals. The unit is supplied as a ready-to-fit component and is identified by model number YSF2128A.

This spare restores the rear sealing surface and attachment points, helping to maintain correct alignment for exhaust outlets and drive components. Before installation, check mating surfaces, seals and gaskets for wear and ensure the replacement reproduces the original part's clearances to prevent unwanted bearing or crankshaft loads.

Fitting the back plate is a routine service step for DZ140 engines; adhere to the engine manufacturer's disassembly and reassembly instructions. Begin by hand-tightening fasteners to locate parts, then set final torque values per the service manual. Complete a bench rotation test to confirm free movement before refitting the engine to the model.

Offered as an OEM spare, this back plate assembly provides the direct replacement needed to restore rear-case function and mounting geometry on DZ140 engines.
