VEGE Remanufactured VD58 5.2L 318ci Heavy Duty Long Block Engine

Description

Intake plenum belly pan gasket blowout and premature valve guide wear disappear after installing the VEGE Remanufactured VD58 5.2L Long Block Engine. Generating 230HP from a 318ci 8-Cylinder commercial long block repower layout, this engine powers fleet delivery trucks. Mechanics must verify distributor drive gear backlash against the intermediate shaft drive gear before torquing down the distributor hold-down clamp.

Heavy-duty ASTM A48 Class 35 gray iron forms the engine block, providing lasting structural resistance against chassis vibration under payload. The VEGE engine core employs induction-hardened nodular iron camshaft lobes paired with stellite-faced exhaust valves. Starter current demands 12V 175A draw under load. Total dry weight measures 485 lbs across a 27in length, 26in width, 27in height mounting stance holding 5.0 quarts oil capacity.

Key Features of VEGE VD58

Municipal utility fleets buy VEGE VD58 commercial long block assemblies to end chronic intake oil ingestion across aging service vehicles. Dedicated technicians execute certified industrial engine rebuild standards during each assembly phase.

• Cast nodular iron crankshaft maintains 0.0003in TIR total indicated runout across all main bearing journals.
• Heavy-gauge steel belly pan plates replace stamped factory pans to eliminate crankcase vacuum oil leaks.
• Diamond-honed iron cylinder sleeves establish immediate compression ring seal during initial break-in running.
• Precision CNC surfaced block decks yield 0.0002in flatness to preserve cylinder head fire ring integrity.
• High-volume internal oil pump sustains 50 PSI line pressure across demanding fleet highway duty.
• VD58 commercial core casting includes reinforced main bearing web bulkheads 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 230 continuous BHP and 295 ft-lbs torque output at 4000 RPM continuous sweep testing. Instrumentation logs 52 PSI oil gallery pressure at 195°F oil sump temperature, while exhaust gas temp records 1220°F under dyno pull. Gauge checks verify 175 PSI compression across all eight cylinders within 4% variance. Center journal deflection clocks at 0.0003in TIR on the VD58 long block engine.

Field Service Directives Maintenance Rules

Mechanical throttle lever operation takes 5 lbs pull force through the linkage bracket assembly. This motor is NOT engineered for marine salt-water applications or light front-wheel drive passenger car conversions. Certified technicians must carry out standardized shop procedures during initial checkout.

• Drain break-in crankcase oil supply and replace filter element at 500 miles.
• Set hydraulic lifter preload depth between 0.035in and 0.045in before valve cover installation.
• Verify cylinder head bolt tension values following manufacturer sequences after 50 operating hours.

Warranty Statement Crate Manifest Contents

All rebuilding procedures meet strict VEGE assembly standard metrics covered by a 3-Year 100,000-mile warranty. The banded transport pallet holds the assembled long block, steel oil pan, aluminum timing cover, composite valve covers, oil pickup screen, and verified dyno run card.
