VEGE Remanufactured VFW2 6.8L 415ci Premium Grade Long Block Engine

Description

Spark plug blowout and roller follower needle bearing ejection disable heavy municipal motorhomes and Super Duty utility trucks. The VEGE Remanufactured VFW2 Long Block Engine resolves valvetrain breakdown through an industrial engine rebuild specification. This 6.8L 415ci 10-Cylinder powerplant produces 310HP. Technicians must check balance shaft drive gear timing alignment within the front engine cover prior to final torquing.

Engineers construct the crankcase from ASTM A48 Class 35 cast iron with cross bolted main bearing caps. The VEGE engine core utilizes a counterweighted split pin nodular iron crankshaft, forged connecting rods, and an overhead balance shaft. Cranking circuits draw 185A through 12V starter motors. Engine dry weight reaches 640 lbs with exterior proportions of 31in length, 28in width, 29in height, holding a 6.5 quarts oil pan.

Key Features of VEGE VFW2

Fleet maintenance supervisors buy VEGE VFW2 Long Block Engine packages to keep heavy emergency vehicles on active service. Precision CNC thread inserts reinforce spark plug wells to eliminate blowout risks during each commercial long block repower.

• 10-Cylinder cross bolted iron block provides lower end rigidity under continuous towing strain.
• 20-Valve heads feature full length steel spark plug thread inserts in every chamber.
• 6.8L displacement delivers 425 ft-lbs torque for transporting loaded commercial chassis cabs.
• 0.0015in rod journal clearance ensures fluid lubrication under continuous load cycles.
• Internal balance shaft cancels uneven V10 rocking couples to smooth driveline operation.
• Cast iron timing tensioners replace plastic units to ensure positive chain control.
• VFW2 commercial core assemblies arrive with high volume gerotor oil pumps preinstalled.
• Multi layer steel head gaskets maintain combustion seals under extreme thermal loads.

Dynamometer Heavy Duty Test Benchmarks

Hot cell brake tests establish 310BHP and 425 ft-lbs torque at 4250 RPM on the VFW2 long block engine. Gallery pressure sensors verify 55 PSI continuous oil delivery at 195°F oil bath operating temperature under load. Cylinder compression gauges show 185 PSI across all ten bores with variance held under 3% between cylinder banks. Pyrometer probes record 1220°F peak exhaust temperature under dyno brake loads. Precision bench indicators confirm crankshaft journal runout remains below 0.0003in TIR across finished surfaces.

Field Installation Directives Exclusions

Mechanical throttle cable linkage brackets demand 6 lbs pull effort to stroke the throttle body mechanism during pedal travel. This engine is not built for passenger sports coupes, light front drive minivans, or compressed natural gas conversions without hardened valves.

• Drain initial break-in motor oil at 500 miles and replenish the crankcase with API approved 5W-20 mineral oil.
• Stationary hydraulic lash adjusters set zero lash without manual shims or periodic maintenance service intervals.
• Main cap side cross bolts require specific sequence torquing to prevent crankcase skirt distortion during service.

Warranty Protection Shipment Manifest
