VEGE Remanufactured VC25 6.0L 366ci Heavy Duty Long Block Engine

Description

Burnt exhaust valves and worn piston ring lands cause severe blowby and crankcase pressurization on heavy dump trucks. The VEGE Remanufactured VC25 Heavy Duty Long Block Engine cures commercial fleet downtime during an industrial engine rebuild project. This tall deck 6.0L 366ci 8-Cylinder brute generates 235HP. Technicians must confirm tall deck intake manifold spacer positioning before manifold torquing.

Massive ASTM A48 Class 35 cast iron forms the tall deck engine block and high nickel cylinder heads. A forged AISI 1045 steel crankshaft turns within tri-metal copper lead main bearings inside this VEGE engine build. Heavy duty 12V starter motors draw 190A during cold engine cranking. The unrigged dry package weighs 660 lbs with dimensions of 32in length, 28in width, 30in height. The extra capacity steel oil pan holds 7.0 quarts.

Key Features of VEGE Remanufactured VC25

Fleet directors buy VEGE Remanufactured VC25 Heavy Duty Long Block Engine units to rebuild severe service medium duty trucks. Every commercial long block repower integrates commercial grade heavy truck components that handle continuous governor limit operation.

• Tall deck iron block casting provides extra deck height for four ring commercial truck pistons.
• Forged steel crankshaft withstands severe torsional vibration under heavy gross vehicle weight loads.
• Sodium cooled exhaust valves resist heat deformation during hours of continuous full throttle pulling.
• The VC25 commercial core features induction hardened valve seats designed for heavy industrial use.
• 0.0020in rod journal clearances maintain ample hydrodynamic oil wedges under sustained grade climbing.
• Double roller steel timing sets prevent timing wander under continuous governor speed governing.
• Stellite valve face overlays prevent seat recession under severe commercial thermal loading.

Dynamometer Performance Test Benchmarks

Dynamometer cell testing rates this VC25 long block engine at 235 BHP and 385 ft-lbs of continuous torque at 2600 RPM. Main oil galleries deliver 60 PSI at 195°F oil pan thermal equilibrium. Exhaust gas thermocouple probes register 1210°F during sustained max load cycles on the water brake absorber unit. Compression testing confirms 175 PSI across all eight cylinders within 3% balance across both cylinder banks. Crankshaft total runout measures under 0.0003in TIR to preserve heavy duty main bearing shells under load.

Commercial Mechanical Chassis Parameters

Mechanical governor throttle linkage rods demand 6 lbs of return spring force for positive idle shutdown. This tall deck commercial engine is NOT compatible with standard deck passenger car big block intake manifolds, marine ski boats, or small chassis pickup trucks.

• Drain break-in motor lubricant and replace spin-on oil filter elements at 50 hours or 500 miles.
• Set adjustable hydraulic lifters to zero lash plus one-half turn down during initial valve adjustment.
• Retorque tall deck cylinder head fasteners after 50 operating hours to maintain fire ring clamping.

Crate Contents Commercial Warranty

Engineered to meet the stringent VEGE assembly standard, this heavy duty unit includes a 3-Year 100,000-mile parts warranty. The timber freight crate encloses the long block, deep commercial oil pan, cast timing cover, steel valve covers, pickup tube screen, and signed dynamometer test sheet.
