Connecting Rod Assembly for Weichai WP12 Engine — OEM 612630020017 (Shacman / Sinotruk)
This connecting rod assembly (OEM part number 612630020017) is manufactured for the Weichai WP12 12-liter heavy-duty diesel engine, one of the most widely deployed commercial vehicle powerplants in the world. The WP12 powers the Shacman X3000/F3000, Sinotruk HOWO, and Hongyan heavy trucks, as well as large-tonnage forklifts, wheel loaders, and construction machinery. Each cylinder in a WP12 engine produces immense torque — and the connecting rod is the component that converts that explosive downward piston force into crankshaft rotation, experiencing alternating tension and compression loads that can approach 200 kN at rated power. A WP12 connecting rod failure — whether from fatigue cracking at the beam, big-end bolt stretch, or bushing seizure — results in a ventilated engine block and total engine loss. Quality replacement rods are mandatory for any WP12 engine overhaul or rebuild.
Forged from premium heat-treated alloy steel (typically 40CrNiMo or equivalent grade) in a closed-die forging process, this connecting rod achieves optimal grain flow orientation along the highly stressed beam section for maximum fatigue resistance under millions of load cycles. The big-end bore, small-end bushing bore, and bolt holes are CNC-machined to Weichai factory tolerances, ensuring precise bearing crush, correct bushing interference fit, and accurate bolt clamping load. The cap-to-rod interface is fracture-split for perfect alignment and positive engagement under load, while the beam is shot-peened to induce compressive surface stress for improved fatigue life. Each rod is individually magnaflux-inspected for surface cracks and weight-matched to ensure balanced engine operation.
Direct replacement for Weichai WP12 engines in Shacman X3000/F3000/M3000, Sinotruk HOWO, Hongyan Genpaw, and large forklifts and construction equipment. Also fits Weichai-powered generator sets, marine engines, and industrial power units using the WP12 platform. Always install with new big-end bearing shells, new rod bolts with proper angle-tightening, and assembly lubricant on all bearing surfaces.
