DEUTZ BF6L913 Crankshaft 0293 1058 | Engine Exporter – China Direct

As a factory-direct exporter of DEUTZ BF6L913 series rotating assemblies, we supply the crankshaft 0293 1058 – a six-throw, fully counterweighted forging that serves as the structural backbone for 6.0L naturally aspirated and turbocharged variants commonly installed in coastal fishing trawlers, 40-tonne heavy haulage trucks, and irrigation pump stations. Our production adopts a multi-stage induction hardening process on all main bearing journals (Ø100mm) and crankpins (Ø80mm), achieving a hardened depth of 3.5–4.5mm with a consistent 52–56 HRC surface to resist abrasive wear from high-soot lubricants. Critically, we machine this crankshaft with precision-phased index grinding, holding runout within 0.02mm and mass imbalance below 8g·cm – parameters that directly correlate with vibration-free operation at sustained 2200 RPM. For overhaul shops, we offer both standard-size and service undersize variants (0.25mm, 0.50mm, 0.75mm) for reground bearings, accompanied by a matched fillet radius chart to avoid stress-riser fractures during reassembly. Unlike traders who resell mixed foundry batches, we apply individual serial-number engraving on the front counterweight, enabling full traceability back to our heat-treatment furnace logs. We also package each crank in a custom wooden crate with anti-rust VCI film and end-cap protectors, ensuring zero transit damage even for LCL sea shipments to remote port destinations.
