VEGE Remanufactured DFY5 5.4L 330ci High Output Long Block Engine

Description

Camshaft phaser advance vane chatter and roller rocker needle bearing release cease after installing the VEGE Remanufactured DFY5 5.4L Long Block Engine. Generating 310HP from its 330ci 8-Cylinder commercial long block repower layout, this unit drives commercial service trucks. Installers must check variable cam timing solenoid screen cleanliness before securing front timing covers to prevent oil passage clogging.

An ASTM A48 Class 35 cast iron block provides rigid cylinder wall stabilization under high thermal loading. The VEGE engine core integrates induction-hardened nodular iron crankshaft journals and stellite-faced valves. Cranking starter demand requires 12V 190A. Engine dry weight measures 530 lbs inside a 28in length, 27in width, 28in height stance holding 7.0 quarts oil.

Key Features of VEGE DFY5

Municipal utility fleets buy VEGE DFY5 commercial long block packages to restore long-distance route fleet dependability. Modern clean-room shops enforce verified industrial engine rebuild benchmarks throughout each production cycle.

• Forged micro-alloy steel crankshaft maintains 0.0003in TIR centerline runout across all main journals.
• Precision-machined cam phaser internal lock pins prevent cold-start valvetrain chatter.
• Plateau-honed cylinder liners establish immediate compression ring seal during break-in running.
• Precision CNC surfaced block decks yield 0.0002in flatness to preserve cylinder head fire ring integrity.
• High-capacity internal oil pump sustains 60 PSI line pressure across demanding fleet highway duty.
• DFY5 commercial core layout uses structural webbing along the lower crankcase to arrest chassis vibration.
• Tri-metal copper-lead bearings deliver 0.0015in clearance to control severe hydrodynamic bearing stress.

Dynamometer Calibration Bench Load Data

Automated test cells indicate 310 continuous BHP and 365 ft-lbs torque output at 3750 RPM continuous sweep testing. Instrumentation logs 58 PSI oil gallery pressure at 195°F oil sump temperature, while exhaust gas temp records 1260°F under dyno pull. Gauge checks verify 180 PSI compression across all eight cylinders within 4% variance. Center journal deflection clocks at 0.0003in TIR on the DFY5 long block engine.

Field Service Guidelines Operating Boundaries

Accelerator lever actuation demands 5 lbs pull force on the return spring pivot assembly. This power plant is NOT engineered for transverse vehicle platforms or vehicles equipped with mechanical flat-tappet conversion systems. Field mechanics must follow our strict commercial service maintenance schedule.

• Empty initial break-in lubricant reservoir at 500 miles or 30 run hours.
• Inspect hydraulic lash adjusters for proper oil priming before starting the engine.
• Verify cylinder head bolt clamping torque using factory angle-gauge procedures after initial run.

Warranty Statement Crate Manifest Contents
