YS Engine YSF4128A Back Plate Assembly for DZ140 and DZ160 Engines  [YSF4128A]

Back plate assembly for DZ140/DZ160

The YS Engine YSF4128A back plate assembly is an RC-scale replacement component designed for the DZ140 and DZ160 engine families. It serves as the rear housing interface that secures the crankcase closure and aligns rear-mounted components during routine service or rebuilds.

This part is intended for model-scale engine maintenance and tuning. When replacing the back plate, inspect mating surfaces for wear, confirm gasket condition, and verify that fastener threads are clean to ensure a proper seal and alignment. The assembly supports standard teardown and reassembly workflows used in nitro engine servicing.

Fitment is limited to the DZ140 and DZ160 designations shown in the product name. Before installation, confirm the engine model and compare locating features to the original plate to avoid mismatches. The component is offered as a direct spare rather than an upgrade item, and it integrates into existing YS Engine mounting and sealing arrangements for these models.

Use this back plate assembly when servicing DZ140 or DZ160 engines to restore rear case alignment and sealing; verify parts before fitment and follow standard engine rebuild procedures.
