VEGE Remanufactured VF43 4.9L 300ci Heavy Duty Long Block Engine

Description

Restore legendary inline gear drive durability with the VEGE VF43 Long Block Engine, built for commercial long block repower needs in medium duty delivery trucks. This 4.9L 300 cid Inline-6 produces 150HP at 3,400 RPM. Installers must inspect fiber or steel cam drive gear mesh backlash because incorrect gear clearance causes severe front geartrain whine.

Solid ASTM A48 Class 35 cast iron shapes the massive 6-cylinder inline block. A forged steel crankshaft pairs with heavy beam connecting rods inside this VEGE engine core. Starter draw measures 165A on 12V commercial circuits. Dry weight scales at 515 lbs across dimensions measuring 34in length by 21in width by 28in height. Oil capacity holds 6.0 quarts.

Key Features of VEGE VF43

Fleet supervisors buy VEGE VF43 Long Block Engine units to restore delivery truck reliability during an industrial engine rebuild cycle. Direct gear to gear camshaft drive eliminates timing chain stretch and breakage over hundreds of thousands of hours.

• Cast iron cylinder heads house heavy duty valve seats to withstand high thermal exhaust gas heat.
• Direct gear driven camshaft design eliminates timing chain stretch across severe fleet usage.
• Hypereutectic pistons resist ring land micro welding under severe stop and go delivery cycles.
• The VF43 commercial core holds 0.0016in connecting rod bearing clearance for dependable oil films.
• Seven main bearing saddles provide complete crankshaft support against heavy torque loads.
• High volume oil pumps circulate lubricant through internal galleys to prevent journal wear.
• Multi layer steel head gaskets stop combustion blow by across the deck under heavy mechanical strain.

Dynamometer Bench Testing Thermal Ratings

Dynamometer pulls certify 150HP at 3,400 RPM and 260 ft-lbs torque at 2,000 RPM for this VF43 long block engine. Pressure transducers indicate 52 PSI oil gallery pressure at 2,000 RPM while maintaining 195°F coolant operating temperature. Combustion chamber compression balances at 170 PSI across all six cylinders within 4% variance. Crankshaft dial indicators verify 0.0002in TIR total runout. Exhaust pyrometers register 1,180°F under sustained full brake load.

Field Usability Preventive Maintenance Schedules

Mechanical throttle linkages require 4 lbs pull force to sweep from idle stop to wide open throttle. Fleet maintenance shops should not choose this heavy duty replacement engine for light vehicle chassis lacking length clearance for 34in inline 6 engine blocks or vehicles with low capacity cooling cores.

• Drain break in crankcase oil after 500 miles or 30 run hours then install fresh 10W-30 motor oil.
• Inspect cam gear timing index marks before installing the stamped steel timing cover.
• 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 cover, oil pump pickup tube, plus certified remanufacturing inspection sheets.
