The 3791290 turbocharger (Model HX40G) is a direct‑replacement turbo unit for Sinotruk‑Weichai WP7 diesel engine. It delivers stable compressed‑air supply for highway haulage and harsh construction‑site operating conditions. Customers shall cross‑validate spare‑part identity by assembly number 3791290, with factory customer number 610800110869 for internal reference only. Note that slight differences in actuator calibration and spring preload may exist, do not interchange directly without verification of engine OE number.

Overview

Product Details

The HX40G turbocharger is a next‑generation heavy‑duty turbo platform engineered for heavy‑duty trucks and construction machinery. It delivers class‑leading boost response, stable pressure output and export‑ready reliability for fleets and repair shops for replacement and upgrade.

Designed around mature turbocharger development experience, the HX40G integrates precision aerodynamic design, high‑strength material and proven bearing‑sealing technology to help operators reduce total maintenance cost while maintaining strong performance under heavy‑load.

Product Advantages

Strong Boost Performance

Reliable mid‑low‑speed boost response for WP7 heavy‑duty diesel engine
Adequate air flow delivery for full‑load climbing and heavy‑haul scenarios

Intelligent & Stable Operation

External wastegate actuator accurately controls boost pressure and prevents over‑boost
Optimized flow‑path geometry reduces compressor‑surge risk under variable load
Maintains steady power output during long‑time continuous running

Safe and Reliable

High‑temperature resistant turbine wheel alloy withstands severe exhaust thermal shock
Optimized bearing‑sealing assembly lowers oil‑leakage failure probability
Strict full‑scale high‑speed dynamic balance testing to extend service lifespan
