VEGE Remanufactured DFX8 3.0L 181ci Compact Car Long Block Engine

Description

High tensile gray iron anchors the VEGE DFX8 Compact Car Long Block Engine during your commercial long block repower. This 3.0L 181ci 6-Cylinder engine produces 150HP for commercial fleet transport. Install mechanics must verify camshaft position sensor drive gear tooth wear on the oil pump drive shaft because worn gears cause erratic spark timing and backfires.

Heavy duty ASTM A48 Class 30 gray iron casting creates the rigid 60-degree V6 cylinder block. This VEGE engine core features an induction hardened nodular iron crankshaft and forged steel connecting rods. Austenitic 21-4N valves seat against hardened induction iron faces. The 12V starter draws 150A under cold crank tests. Bare dry weight measures 340 lbs across dimensions of 24in length, 23in width, 24in height, with 4.5 quarts oil capacity.

Key Features of VEGE DFX8

Plant supervisors buy VEGE DFX8 Compact Car Long Block Engine packages to complete a severe industrial engine rebuild with minimum equipment downtime. Precise computerized horizontal line honing ensures main bearing alignment to eliminate crankshaft journal binding under transit loads.

• A compact 3.0L 181ci displacement base delivers high flat-plane torque for municipal routes.
• Two-bolt wide stance main bearing caps anchor the bottom end to stop journal deflection under load.
• Plateau honed cylinder walls allow fast compression ring seating within initial engine run hours.
• The DFX8 commercial core camshaft profile maximizes low RPM pulling force for fleet utility beds.
• High volume oil pump gears deliver constant fluid pressure to overhead rocker arm assemblies.
• Premium elastomer front and rear main seals stop motor oil leakage across extreme fleet shifts.
• Deep thread cylinder head bolt bosses prevent thread distortion under severe combustion pressure.

Dynamometer Verification Operational Thresholds

Dyno load cell verification proves this DFX8 long block engine produces 150HP and 180 ft-lbs of shaft torque at 4,800 RPM. Testers sustain a 2,200 RPM continuous load while oil gallery pressure holds between 42 PSI and 58 PSI. Engine oil sump temperature reads 190°F and exhaust gas heat levels reach 1,180°F. Compression testing confirms 170 PSI across all six cylinders within 4% variance. Crankshaft journal runout measures 0.0003in TIR to verify true rotational alignment.

Field Installation Maintenance Protocols

Throttle linkage return springs must exert 5 lbs pull force to guarantee positive mechanical throttle closure. Do not drop this commercial replacement engine into lightweight passenger coupes without front suspension upgrades. Maintenance crews must carry out essential shop preventive routines.

• Perform break-in oil drainage and filter changeout at 500 miles or 25 operating hours.
• Adjust mechanical rocker arm pivot bolts cold to establish 24 ft-lbs clamp torque down.
• Retorque cylinder head bolts to factory specifications following initial operating thermal cycles.

Crate Manifest Coverage Terms

All rebuilding methods comply with the VEGE assembly standard backed by a 3-Year 100,000-mile parts warranty. The timber shipping crate houses the sealed long block core, steel oil pan, front timing cover, stamped valve covers, oil pickup tube, and the inspector verification sheet.
