VEGE Remanufactured 861A 3.5L 3456cc Car Truck Long Block Engine

Description

Valvetrain clatter and variable timing camshaft phaser rattle disappear after installing the VEGE Remanufactured 861A 3.5L Long Block Engine. Engineered for demanding duty, this 3456cc 6-Cylinder commercial long block repower outputs 270HP for fleet vehicles. Technicians must inspect oil delivery banjo bolt filter screens prior to final assembly to preserve unobstructed oil feed to cam gears.

An ASTM A356-T6 aluminum block casting houses spiny cast-iron cylinder sleeves for exceptional heat transfer. The VEGE engine core utilizes micro-finished forged steel camshafts paired with stellite-faced exhaust valves. Starter current demands 12V 165A draw under load. Total dry weight measures 375 lbs across a 25in length, 24in width, 26in height mounting stance holding 6.1 quarts oil capacity.

Key Features of VEGE 861A

Municipal fleet maintenance hubs buy VEGE 861A commercial long block packages to stop recurring camshaft gear breakdown across transport vans. Dedicated technicians execute certified industrial engine rebuild standards during each assembly phase.

• Forged 4140 steel crankshaft maintains 0.0003in TIR total indicated runout across all main journals.
• Tri-metal copper-lead bearings establish 0.0014in clearance for superior hydrodynamic protection under full throttle.
• Diamond-honed cylinder liner walls promote rapid compression ring seating without excess cylinder wall friction.
• Precision CNC surfaced block decks yield 0.0002in flatness to preserve cylinder head fire ring integrity.
• Dual high-pressure oil control solenoids receive dynamic flow testing to prevent cam advance lag.
• 861A commercial core architecture incorporates reinforced crankcase cross-bolting to stop high-RPM block distortion.
• Moly-graphite skirt coatings reduce piston friction across severe stop-start urban delivery routes.

Dynamometer Calibration Bench Load Data

Automated dynamometer validation records 270 continuous BHP with 248 ft-lbs torque output at 4700 RPM continuous test load. Fluid sensors confirm 50 PSI oil gallery pressure at 195°F oil sump temperature, while exhaust gas temp checks at 1250°F during full pull. Testing confirms cylinder compression at 185 PSI across all six cylinders within 3% variance. Center journal deflection measures 0.0003in TIR on the 861A long block engine.

Chassis Fitment Operational Maintenance Directives

Throttle cam return spring pull effort registers 5 lbs force on the accelerator lever bracket. This motor is NOT engineered for longitudinal rear-wheel drive trucks requiring deep front-sump steel oil pans. Mechanics must follow standardized maintenance intervals during initial engine operation.

• Drain initial break-in engine oil reservoir at 500 miles or 30 operating hours.
• Check cold bucket tappet clearance at 0.007in intake and 0.011in exhaust before installation.
• Retorque water crossover pipe bolts after the initial engine warm-up cycle.

Warranty Coverage Packaged Core Manifest

Manufacturing adheres to VEGE assembly standard metrics covered by an extensive 3-Year 100,000-mile parts warranty. The timber transport enclosure holds the assembled long block engine, aluminum lower pan, front timing gear cover, dual valve covers, oil pickup screen, and verified dyno report.
