Restore continuous high RPM valvetrain output with the VEGE 555A High Output Long Block Engine built for commercial long block repower projects in performance fleet machinery. This 1998cc 4-Cylinder assembly produces 200HP through dual overhead camshaft variable valve lift geometry. Installers must prime the secondary rocker arm oil circuit prior to ignition to prevent high cam wear.

Cast from heat treated A356-T6 aluminum alloy with ductile iron sleeves, the engine block joins a high velocity aluminum cylinder head. Each VEGE engine core undergoes magnetic particle crack testing, deck milling within 0.0002in flatness, and CNC line boring. The 12V starter system draws 175A under cold cranking tests. Unrigged dry weight registers 285 lbs across a 25in length by 22in width by 24in height mounting stance. Sump holds 4.8 quarts of 5W-30 oil.

Key Features of VEGE 555A

Fleet operators buy VEGE 555A High Output Long Block engines to complete an industrial engine rebuild requiring high output reliability. Modern remanufacturing operations restore all reciprocating internal components to original factory blueprint specifications.

- 1998cc displacement produces 142 ft-lbs torque across high RPM speed ranges.
- Dual overhead camshaft valvetrain features variable valve lift lobes for maximum intake airflow.
- Ductile iron cylinder sleeves provide maximum bore stability under sustained high output operation.
- The 555A commercial core receives precision diamond hone finishing across all 4 cylinder bores.
- Forged steel crankshaft journals undergo micro polishing to maintain hydrodynamic oil wedges under load.
- Multi layer steel head gaskets eliminate combustion blow by under aggressive throttle settings.
- High performance valve springs prevent valvetrain float up to 8,200 RPM operational limits.

Dynamic Load Bench Tolerances

On the water brake dynamometer, the 555A long block engine produces 200 continuous BHP at 7,400 RPM and 142 ft-lbs torque at 6,000 RPM. Crankcase oil gallery pressure stabilizes at 62 PSI during high cam engagement with sump oil held at 195°F. Exhaust pyrometer probes measure heat under 1,280°F under continuous full throttle pulls. Compression gauges verify 200 PSI across all 4 cylinders with less than 3% variance. Crankshaft journal runout measures 0.0003in TIR, holding main bearing oil clearances between 0.0010in and 0.0015in.

Field Service Maintenance Rules

Throttle linkage calls for 5 lbs pull force for crisp butterfly valve response across the complete travel arc. Do not install this 2.0L high output replacement engine into heavy low speed industrial tractors or continuous load irrigation pumps that lack high RPM cooling airflow.

- Change engine oil and spin on filters every 3,000 miles or 150 run hours with 5W-30 synthetic lubricant.
- Inspect valvetrain lash and timing chain tensioner travel every 15,000 miles cold.
- Retorque cylinder head bolts to 65 ft-lbs after the initial 50 operating hours under load.

Warranty Terms Crate Contents

VEGE assembly standard terms back every long block with a 3-Year or 100,000-mile limited warranty. The heavy wooden shipping crate holds the assembled long block core, cast aluminum oil pan, oil pickup tube, valve cover, timing chain cover, and factory dynamometer inspection verification sheets.
