Lycoming LRT23381 Hydraulic Roller Tappet Assembly – Genuine OEM (very low Time 40 hrs since new)

Original Lycoming hydraulic roller tappet body assembly, part number LRT23381. This is a genuine OEM aircraft engine component, removed from a low-time factory remanufactured engine that was disassembled following aircraft decommissioning (PA-23 platform, Europe).

This unit represents the modern roller tappet configuration introduced by Lycoming to significantly reduce camshaft and lifter wear compared to legacy flat tappet designs.

The assembly is in excellent used condition, with approximately 40 hours since new, showing only minimal, uniform contact patterns consistent with normal operation. No abnormal wear, scoring, pitting, or mechanical play observed.
