YSF2128A Back Plate for DZ140 Engine Series by YS Engine  [YSF2128A]

Rear Back Plate for DZ140

This YS Engine back plate assembly is supplied for DZ140 engine series maintenance as a replacement rear cover designed to interface with the engine case and internal components. The part is supplied ready to fit and is identified by model YSF2128A.

The unit replaces the rear sealing surface and mounting features, helping to maintain correct alignment of exhaust outlets and drive interfaces. Before fitting, examine mating faces, seals and bearings for wear and confirm that the replacement reproduces the original clearances to avoid added load on the crankshaft or bearings.

Fitting the back plate is a routine workshop task for DZ140-powered models; follow the manufacturer's instructions for disassembly and reassembly. Hand-tighten fasteners first to locate parts, then apply the service torque values from the manual. Perform a bench rotation and leak check after installation to verify correct fit before running the engine in the model.

As an OEM spare, this back plate assembly provides a direct replacement route to re-establish rear-case integrity and mounting geometry on DZ140 RC engines.
