VEGE Remanufactured DC76 4.1L 250ci Premium Grade Long Block Engine

Description

Extended component longevity guides fleet mechanics toward the VEGE Remanufactured DC76 Premium Long Block Engine for high-uptime delivery vehicles. This 4.1L 250ci straight-six produces 115HP with upgraded valve metallurgy and strict balancing. The extended inline cylinder layout requires straight exhaust routing to clear steering shaft components in tight engine bays.

High-density ASTM gray iron construction reinforces cylinder walls against thermal distortion during stop-and-go driving. The 7-journal bottom end anchors a balanced nodular iron crank. Tailored for 12V electrical infrastructure, starter demand peaks at 165A under sub-zero cranking conditions. The unit weighs 445 lbs unrigged with a physical envelope of 31in length by 22in width and 28in height. The stamped steel sump holds 5 quarts of oil.

Key Features of VEGE Remanufactured DC76

Light transport operators buy VEGE Remanufactured DC76 engines to repower legacy route trucks that require exceptional operational reliability. This premium grade package features tighter component balance tolerances for extended commercial service life.

• Premium grade induction hardened valve seats withstand unburned fuel deposits under variable load.
• Balanced connecting rods reduce harmonic vibration through the entire 4,000 RPM range.
• Moly faced compression rings provide tight cylinder bore sealing with minimal ring land wear.
• High pressure oil pump pushes 50 PSI hot through rifle-drilled oil passages.
• Precision ground camshaft lobes optimize low-end torque production between 1,400 RPM and 2,600 RPM.
• Heavy duty steel timing gear train eliminates timing belt slack and chain stretch.
• 7 tri-metal main bearings protect journals from galling during cold dry start conditions.

Dynamic Dynamometer Thermal Analysis

Dynamometer runs establish 115HP at 3,800 RPM alongside 200 ft-lbs torque output at 1,800 RPM on standard commercial fuels. Oil pressure holds 48 PSI at operating temperature while coolant flow keeps operating temperatures at 182°F. Pyrometer gauges confirm exhaust manifold heat within 1,150°F during full load step tests. Compression measurements verify 150 PSI across all 6 cylinders within 2% deviation. Crankshaft total indicated runout checks below 0.0003in TIR with thrust float set at 0.004in.

Engine Bay Operator Limits

Throttle lever pull force requires 6 lbs to overcome dual throttle return springs. Do not install this premium grade inline-six in front-wheel drive platforms, boats, or vehicles without adequate front axle load capacity. Fleet maintenance teams must check transmission bellhousing dowel alignment to prevent input shaft pilot bushing binding.

• Renew 10W-30 motor oil and filter every 250 hours or 3,000 service miles.
• Inspect valve train rocker geometry and pushrod ends every 800 run hours.
• Verify intake manifold torque at 25 ft-lbs every 400 operating hours.

Verified Crate Manifest Warranty

VEGE protects this premium long block with a 3-Year or 100,000-mile commercial powertrain warranty. The wooden freight crate contains the remanufactured long block core, premium valve cover, oil pan, front timing cover, oil pickup tube, basic gasket set, and certified build inspection sheet.
