Product Description
10BF11-05020 Crankshaft is the primary rotary core fitted within DFCV EQ4H diesel engine block. Working in coordination with connecting rods, it translates the linear thrust released by cylinder combustion into continuous rotational torque to drive the gearbox and auxiliary attachments. This aftermarket crankshaft resolves fluctuating oil pressure, recurring metallic rattle and premature bearing failure caused by journal scuffing, out-of-tolerance bending and subsurface fatigue cracks accumulated under frequent variable loads. Fine surface finishing preserves stable oil film and smooth power delivery, lowering breakdown risks for medium-heavy trucks assigned to regional distribution and hilly-area hauling tasks.
Product Advantages Fabricated from high-grade forged alloy steel with customized thermal treatment workflow. Main journals and crank pin surfaces receive hardening treatment to combat abrasive wear. Counterweights are carefully profiled to counteract inertial force from reciprocating assemblies. Each crankshaft passes non-destructive crack scanning and dynamic balancing calibration before packaging, matching OEM journal diameters and flange hole layout for seamless engine reconstruction.

FAQ
Q1: What signals indicate surface damage or hidden cracks on crankshaft journals?
A1: Erratic engine oil pressure, metallic debris trapped inside oil filter and noticeable vibration under acceleration.
Q2: Why is dynamic balancing such a critical procedure for this crankshaft?
A2: Imbalanced mass generates persistent resonance, which accelerates journal wear and loosens connected components.
Q3: Which parts should be inspected or replaced alongside the new crankshaft?
A3: Main bearing shells, thrust washers and front/rear oil seals should be prepared for matched overhaul.
Q4: What measurement needs finishing once assembly completes?
A4: Check crankshaft end play and runout value strictly to eliminate hidden alignment issues.
