VEGE Remanufactured DFBF 6.8L 415ci Industrial Grade Long Block Engine

Description

Regain sustained hauling power through the VEGE DFBF Long Block Engine, designed for severe commercial long block repower needs in medium duty commercial chassis. This 6.8L 415 cid Triton V10 produces 310HP at 4,250 RPM. Installers must inspect exhaust manifold mounting surfaces on the cylinder head because broken factory studs require precision extraction.

Dense ASTM A48 pearlitic gray iron casts the deep skirt 10-cylinder block. A nodular iron split pin crankshaft with counter rotating balance shaft reinforces this VEGE engine core. Starter draw measures 185A on 12V commercial circuits. Dry weight scales at 640 lbs across dimensions measuring 32in length by 28in width by 29in height. Oil capacity holds 7.0 quarts.

Key Features of VEGE DFBF

Municipal contractors buy VEGE DFBF Long Block Engine units to restore heavy duty trucks during an industrial engine rebuild cycle. Remanufactured cylinder heads receive full thread spark plug inserts to prevent plug thread blowouts under load.

• Cast aluminum cylinder heads feature revised combustion chambers that optimize heat transfer away from valves.
• Single overhead camshafts actuate roller follower arms to minimize frictional drag on cam lobes.
• Hypereutectic pistons resist thermal growth to eliminate bore scuffing under full payload towing.
• The DFBF commercial core holds 0.0016in rod bearing oil clearances for steady hydraulic film support.
• Hydraulic chain tensioners eliminate slack across long dual primary timing chain runs.
• An internal balance shaft neutralizes primary vibration harmonics across odd cylinder firing orders.
• Multi layer steel head gaskets stop combustion blow by across the deck under heavy mechanical strain.

Dynamometer Bench Testing Thermal Ratings

Dynamometer pulls certify 310HP at 4,250 RPM and 425 ft-lbs torque at 3,250 RPM for this DFBF long block engine. Pressure transducers indicate 55 PSI oil gallery pressure at 2,000 RPM while maintaining 195°F coolant operating temperature. Combustion chamber compression balances at 175 PSI across all ten cylinders within 4% variance. Crankshaft dial indicators verify 0.0003in TIR total runout. Exhaust pyrometers register 1,220°F under sustained full brake load.

Field Usability Preventive Maintenance Schedules

Electronic throttle body harness plugs require secure clip engagement to prevent sensor signal dropouts. Fleet mechanics must avoid this heavy duty replacement engine for light vehicle chassis lacking structural crossmembers for 640 lbs engine blocks or vehicles with low capacity cooling cores.

• Drain break in crankcase oil after 500 miles or 30 run hours then install fresh 5W-20 mineral oil.
• Inspect spark plug torque to verify 25 ft-lbs in full thread cylinder head inserts.
• Check cylinder head fasteners in proper sequence reaching 85 ft-lbs following initial thermal cycles.

Crate Inclusions Verified Warranty Terms

The VEGE build standard includes a 3-Year or 100,000-mile limited manufacturer warranty. The heavy wooden crate holds the remanufactured long block core, oil pan, timing cover, valve covers, oil pump pickup tube, plus certified remanufacturing inspection sheets.
