YS Engine YSF2084 Access Screw - Piston Wrist Pin Service Tool  [YSF2084]

Service tool: piston wrist pin access screw

The YS Engine YSF2084 piston wrist pin access screw is supplied as a replacement/service item to permit controlled access to the piston wrist pin and to hold it temporarily during disassembly and reassembly. It is intended for maintenance use and will not change internal engine performance characteristics.

Designed as a mechanical aid rather than an upgrade, this screw assists with pin removal, inspection, and positioning of the piston during servicing. Always check the part reference against your engine's service parts list to confirm compatibility before fitting.

Fitting notes: use the screw only to gain access or to briefly retain the wrist pin while working on the piston. Maintain a clean bench, follow standard teardown safety, and ensure correct alignment before tightening and final reassembly to avoid damage to engine components.
