YS Engine YSF2133 Back Plate Screw Set for DZ140  [YSF2133]

Back plate screw set

This back plate screw set is an RC-scale replacement part listed by YS Engine under model YSF2133 and labeled for DZ140 use. It is intended as a direct spare for the rear plate fasteners on DZ140-class model engines where the original screws are worn, missing, or require renewal.

Functionally the set focuses on secure rear plate retention and straightforward part replacement. It supports routine maintenance tasks that restore correct clamping of the back plate to the engine housing and helps preserve component alignment during running and service.

Installation notes: the screws replace the existing fasteners on the engine rear plate and should be tightened to the same seating and torque practice used previously, checking alignment of the plate and any sealing surfaces before final assembly. The item is sold as a replacement screw set only and does not include gaskets or additional engine parts.
