This main timing chain 13506‑75050 is core power‑transmission component of Toyota 2TR‑FE 2.7L gasoline engine timing system. It connects crankshaft and camshaft, transfers rotational power, accurately controls intake and exhaust valve opening‑closing timing to guarantee normal engine combustion cycle. It is aftermarket replacement for Toyota Hilux, Fortuner, Prado, Hiace and Innova from 2004‑2015。
Adopts high‑grade heat‑treated alloy steel, roller surface nitriding hardening process. Improve tensile strength, fatigue resistance and wear‑resistance, adapt to long‑time high‑speed reciprocating working condition of off‑road and commercial engine. Strict pitch tolerance ensures stable meshing with sprockets.
Common failure symptoms: timing chain elongation & stretch, obvious cold‑start rattling noise from engine front cover, timing angle deviation, rough idle, insufficient power, engine misfire, even risk of valve‑piston collision. Normally replaced together with tensioner, guides and sprockets during timing‑system overhaul. Every timing chain passes tensile‑strength inspection before shipment, matches original link pitch dimension, no modification required for installation. Key single spare‑part for 2TR‑FE engine timing maintenance.
