Product Introduction
This crankshaft is the core power transmission component of Weichai WD615.47 371HP engine for Sinotruk HOWO heavy-duty trucks, responsible for converting the reciprocating motion of piston and connecting rod into rotary motion to output engine power. It bears huge alternating stress, friction and high temperature during engine operation. Made of high-grade forged steel with precision machining and strict balance detection, it guarantees excellent mechanical properties and operational stability, effectively avoiding engine failures such as bending and breaking, and is a key spare part for engine overhaul and maintenance.
Applicable Models
Suitable for all Sinotruk HOWO heavy-duty trucks equipped with Weichai WD615.47 371HP diesel engine, including HOWO A7 Series, HOWO 7 Series, dump trucks, tractor trucks, concrete mixer trucks, sanitation trucks and other engineering special vehicles.
