Dual-Code Confirmed: XCMG 253100711 = 800KII.8.5 Rocker Pin | OEM Spec, In Stock

This XCMG Rocker/Linkage Pin 253100711​ (Drawing No. 800KII.8.5) adopts a dual-code design where the numeric P/N and structural drawing No. cross-verify for easy procurement and traceability. As a high-load pivoting part in the linkage system, the pin is made from quenched & tempered 40Cr (or 42CrMo per OEM drawing) with surface hardening and chrome plating, then precision ground on the OD. Critical dimensions, geometric tolerances, and hardness gradient are inspected piece by piece, with surface roughness controlled to OEM spec. Chamfers and lubrication hole (if applicable per drawing) match the original exactly. When installed at the rocker-linkage pivot with bronze bushings, it resists shear and reciprocating wear to prevent loosening and noise during long-term operation. Assembly dimensions follow OEM drawing for drop-in fit with no machining, suitable for various XCMG host machine linkage pivots. Available by batch with bulk inquiry welcome.
