VEGE Remanufactured 547T 3.5L 3475cc High Output Long Block Engine

Description

A 3475cc displacement profile defines the VEGE 547T High Output Long Block Engine during commercial long block repower projects in heavy transport fleets. This 6-Cylinder assembly produces 255HP through aggressive camshaft timing and a 24-valve configuration. Technicians must check intake plenum gasket port matching during assembly because high velocity airflow paths require perfect flange alignment.

Formed from high tensile A356 aluminum alloy with iron cylinder sleeves, the block joins dual high flow aluminum heads. Each VEGE engine core undergoes sonic wall thickness verification, deck milling to 0.0002in flatness, and CNC line boring. The 12V starter motor pulls 200A during cold turnover. Dry unrigged weight measures 390 lbs across a 28in length by 27in width by 26in height mounting stance. Sump capacity holds 5.0 quarts of 5W-20 oil.

Key Features of VEGE 547T

Fleet operators buy VEGE 547T 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.

• 3475cc displacement produces 250 ft-lbs torque across high demand speed ranges.
• Single overhead camshaft per bank drives 24 valves with induction hardened seat faces.
• Heavy duty iron liners provide maximum bore stability under sustained high output operation.
• The 547T commercial core receives precision diamond hone finishing across all 6 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 6,500 RPM operational limits.

Dynamic Load Bench Tolerances

On the water brake dynamometer, the 547T long block engine produces 255 continuous BHP at 6,000 RPM and 250 ft-lbs torque at 5,000 RPM. Crankcase oil gallery pressure stabilizes at 62 PSI 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 6 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 3.5L 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-20 synthetic lubricant.
• Inspect valvetrain lash and timing belt tension every 15,000 miles cold to ensure timing accuracy.
• Retorque cylinder head bolts to 76 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 covers, timing belt cover, and factory dynamometer inspection verification sheets.
