DZ140 Back Plate Screw Set for RC Engines - YSF2133 by YS Engine  [YSF2133]

Rear plate screw kit

This rear plate screw kit is an RC replacement listed by YS Engine as model YSF2133 and specified for DZ140 use. It provides direct spare fasteners for the rear plate on DZ140-design engines when original screws are corroded, missing, or need renewal.

The set is intended to restore secure rear plate clamping and simplify routine maintenance. Proper fastener seating helps preserve alignment of the plate and adjacent components during running and service.

Installation notes: these screws replace the existing rear plate fasteners and should be tightened to the same seating and torque practice previously used, checking plate alignment and any sealing faces before final assembly. Sold as a replacement screw set only; gaskets and other engine parts are not included.
