VEGE Remanufactured 551A 2.0L 1998cc Multi Purpose Long Block Engine

Description

High tensile aluminum alloy blocks anchor the VEGE 551A Multi Purpose Long Block Engine built for commercial long block repower projects in industrial utility machinery. This 1998cc 4-Cylinder assembly produces 160HP through dual overhead camshaft timing chain architecture. Riggers must verify timing chain tensioner unlock pins are retracted before final valve cover installation to ensure correct chain tension.

Cast from A356-T6 aluminum alloy with centrifugally spun ductile iron sleeves, the engine block connects to a high flow aluminum cylinder head. Each VEGE engine core undergoes magnetic particle crack testing, deck milling within 0.0002in flatness, and line boring. The 12V starter system draws 165A under cold cranking tests. Unrigged dry weight registers 280 lbs across a 25in length by 22in width by 24in height mounting stance. Sump holds 4.5 quarts of 5W-20 oil.

Key Features of VEGE 551A

Fleet operators buy VEGE 551A Multi Purpose Long Block units to execute an industrial engine rebuild with minimum mechanical downtime. Precision remanufacturing operations restore every moving component to tight factory manufacturing limits.

• 1998cc displacement produces 140 ft-lbs torque across standard industrial load cycles.
• Dual overhead camshaft chain drive controls 16 valves with precision ground valve faces.
• The 551A commercial core receives diamond cylinder hone processing for rapid ring seating.
• Forged steel crankshaft journals undergo micro polishing to reduce journal drag under load.
• Hypereutectic aluminum alloy pistons feature graphite coated skirts to eliminate cold scuffing.
• High strength multi layer steel head gaskets seal combustion chambers against blow by under load.
• Heavy duty timing chain guide rails maintain positive cam synchronization up to 6,800 RPM.

Dynamic Load Bench Tolerances

On the water brake dynamometer, the 551A long block engine produces 160 continuous BHP at 6,500 RPM and 140 ft-lbs torque at 5,000 RPM. Oil gallery pressure maintains 55 PSI under high operating heat with sump temperatures stabilized at 195°F. Pyrometer gauges measure exhaust gas heat levels below 1,240°F under sustained brake load. Compression testing confirms 190 PSI across all 4 cylinders with under 3% variance. Crankshaft journal runout remains below 0.0003in TIR, keeping main bearing oil clearances between 0.0010in and 0.0016in.

Field Service Maintenance Rules

Throttle cable action requires 5 lbs pull force to actuate the intake butterfly without stickiness. Do not install this 2.0L multi purpose replacement engine into high displacement marine drive applications or stationary prime power generator systems requiring continuous governor speeds.

• Change motor oil and spin on filters every 3,000 miles or 150 run hours with 5W-20 specification oil.
• Inspect timing chain tensioner travel and check valve lash every 15,000 miles to factory cold specs.
• Retorque cylinder head fasteners to 65 ft-lbs after the initial 50 operating hours of break in run.

Warranty Terms Crate Contents

VEGE assembly standard protection provides 3-Year or 100,000-mile limited warranty coverage on all internal components. The heavy duty palletized crate includes the complete long block core, cast aluminum oil pan, oil pickup tube, valve cover, timing chain cover, and signed factory test documentation.
