VEGE Remanufactured VFZA 6.8L 415ci Custom Series Long Block Engine

Description

High tensile gray iron anchors the VEGE VFZA Custom Series Long Block Engine. This 6.8L 415ci V10 heavy engine delivers 310HP for high tonnage commercial long block repower requirements. Fleet mechanics must check balance shaft drive timing alignment inside the front timing casing because incorrect gear mesh creates severe secondary cabin vibration.

Deep skirt ASTM Class 35 pearlitic gray iron provides exceptional block rigidity on this VEGE engine core. A balanced micro alloy forged steel crankshaft uses ground journals to handle extended fleet duty cycles. Starter amperage requires 190A on standard 12V circuits. Total dry weight reads 640 lbs within physical dimensions of 32in length by 28in width by 29in height holding 7.0 quarts oil capacity.

Key Features of VEGE VFZA

Fleet maintenance directors buy VEGE VFZA Custom Series Long Block Engine packages to avoid extended chassis downtime during an industrial engine rebuild. Computerized deck machining ensures true surface plane alignment to avert coolant leaks.

• Large 415ci displacement supplies exceptional pulling force across mountainous haul routes.
• Single overhead camshaft design eliminates pushrods and reduces moving valvetrain mass.
• Stellite faced exhaust valves stop seat face erosion under persistent lean fuel delivery.
• Hypereutectic aluminum alloy pistons control thermal expansion to prevent bore scuffing under load.
• The VFZA long block engine features hydraulic timing chain tensioners for silent cam operation.
• Multi layer steel head gaskets seal high combustion pressures against iron block decks.
• Viton valve stem seals stop oil ingestion into combustion chambers during downhill engine braking.

Dyno Bench Output Standards

Bench testing subjects the VFZA commercial core to full dynamometer absorption sweeps. The dynamometer records 310 continuous BHP with 425 ft-lbs shaft torque at 3,000 RPM. Hot gallery oil pressure maintains 58 PSI at 195°F operating temperature. Exhaust gas probes measure 1,360°F maximum temperature under sustained throttle. Cylinder compression delivers 185 PSI with under 3% variance and crank runout within 0.0003in TIR.

Shop Handling Routine Servicing

Drive by wire throttle actuators or mechanical linkages move smoothly against 4.5 lbs pull tension. Do not install this modular V10 platform into shallow vehicle engine bays that lack 32in front-to-back clearances.

• Drain crankcase oil and install new spin-on filter canisters every 4,000 miles.
• Inspect cam timing chains and composite guide wear every 50,000 operating miles.
• Verify cylinder head bolt clamp loads during scheduled major fleet overhauls.

Warranty Inclusions Product Manifest

Remanufacturing follows the exhaustive VEGE assembly standard to deliver peace of mind on the road. The engine includes a 3-Year or 100,000-mile parts warranty against material faults. Inside the heavy crate sits the fully dressed long block core, oil pan, front timing cover, rocker covers, oil pump pickup tube, and quality checklist.
