YS Engine YSF2084 Piston Wrist Pin Access Screw for RC Engine Maintenance  [YSF2084]

Access screw for piston wrist pin - quick overview

The YS Engine YSF2084 piston wrist pin access screw is a service spare made to give controlled access and secure temporary retention of the piston wrist pin during disassembly and reassembly. It is intended as a practical maintenance aid so you can handle the wrist pin area without modifying internal engine components.

This item is supplied as a mechanical convenience rather than a performance upgrade. Use it to steady the piston for pin removal or inspection, to hold piston alignment while servicing, or as a helpful aid during routine teardown. Always confirm fitment by checking the part reference against your engine's service parts list before fitting.

Installation notes: the screw is for access and temporary retainment only while working on the piston wrist pin. Observe normal engine teardown precautions, work on a clean bench, and verify correct alignment before final reassembly to avoid damage to the piston, wrist pin, or connecting rod.
