VEGE Remanufactured 561 2.4L 144ci Heavy Duty Long Block Engine

Description

Facing recurring bottom end knock? Install the VEGE 561 Heavy Duty Long Block Engine for commercial long block repower projects in tough commercial route trucks. This 2.4L 144ci 4-Cylinder assembly produces 142HP through dual overhead camshafts and 16 valves. Mechanics must check transmission bellhousing dowel sleeve alignment during setup because misaligned pins bind the input shaft pilot bearing.

Cast from heavy ASTM A48 Class 35 gray iron, the engine block connects to an A356 aluminum alloy cylinder head. Each VEGE engine core undergoes hot chemical immersion cleaning, line boring, and deck milling to 0.0002in flatness. A 12V starter system draws 180A under cold cranking tests. Total dry weight measures 345 lbs inside a 26in length by 23in width by 26in height mounting stance. Sump reservoir holds 5.0 quarts of 10W-30 lubricant.

Key Features of VEGE 561

Fleet managers buy VEGE 561 Heavy Duty Long Block assemblies to complete an industrial engine rebuild with zero tolerance for downtime. High capacity commercial remanufacturing brings each internal wear surface back to exact factory dimensions.

• 144ci displacement produces 160 ft-lbs torque across demanding commercial route cycles.
• Dual overhead camshaft gear and chain drive actuates 16 valves with hardened stellite seats.
• Cast iron deep skirt cylinder block provides maximum bore rigidity under severe hauling cycles.
• The 561 commercial core receives precision diamond honing on all 4 cylinder walls.
• Forged steel crankshaft journals undergo induction hardening to prevent journal galling under sustained loads.
• Multi layer steel head gaskets maintain high cylinder pressure containment under elevated operating temperatures.
• Heavy duty valve springs prevent valve float past 5,800 RPM operational limits.

Dynamic Load Bench Tolerances

Tested on an automated dynamometer, the 561 long block engine produces 142 continuous BHP at 5,000 RPM and 160 ft-lbs torque at 4,000 RPM. Crankcase oil gallery pressure stabilizes at 58 PSI with sump temperatures regulated at 195°F. Exhaust gas pyrometers read under 1,220°F during full load continuous pull cycles. Compression test gauges verify 185 PSI across all 4 cylinders with less than 3% variance. Crankshaft journal runout measures 0.0003in TIR, while main bearing oil clearance measures between 0.0012in and 0.0018in.

Field Service Maintenance Rules

Mechanical throttle linkage needs 6 lbs pull force for positive accelerator control without binding. Do not install this 2.4L heavy duty replacement engine into lightweight passenger compacts or chassis configurations lacking adequate engine bay width for the wide cast iron block.

• Change engine oil and spin on filters every 3,000 miles or 150 run hours with 10W-30 oil.
• Inspect valve lash and timing chain tension every 15,000 miles, setting valve clearances cold.
• Retorque main cylinder head bolts to 78 ft-lbs after the initial 50 operating hours under load.

Warranty Terms Crate Contents

VEGE assembly standard warranty coverage includes 3-Year or 100,000-mile limited protection. Each palletized shipping crate contains the remanufactured long block assembly, heavy duty steel oil pan, oil pickup screen, front timing covers, cast valve cover, and signed factory inspection verification sheets.
