VEGE Remanufactured DCW7 3.1L 189ci Premium Grade Long Block Engine

Description

High tensile gray iron anchors the VEGE DCW7 Premium Grade Long Block Engine during your commercial long block repower. This 3.1L 189ci 6-Cylinder engine produces 140HP for light commercial transport. Install mechanics must verify intake manifold coolant crossover port gasket alignment because shifting gaskets cause external coolant leaks onto the transmission bellhousing.

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 AISI 1141 connecting rods. Austenitic 21-4N valves seat against hardened induction faces. The 12V starter draws 150A under cold crank tests. Bare dry weight measures 340 lbs across dimensions of 24in length, 22in width, 23in height, with 4.0 quarts oil capacity.

Key Features of VEGE DCW7

Plant supervisors buy VEGE DCW7 Premium Grade 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 3.1L 189ci displacement base delivers dependable power for municipal delivery 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 DCW7 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 DCW7 long block engine produces 140HP and 180 ft-lbs of shaft torque at 3,600 RPM. Testers sustain a 2,000 RPM continuous load while oil gallery pressure holds between 42 PSI and 58 PSI. Engine oil sump temperature reads 188°F and exhaust gas heat levels reach 1,150°F. Compression testing confirms 170 PSI across all six cylinders within 4% variance. Crankshaft journal runout measures 0.0002in TIR to verify true rotational alignment.

Field Installation Maintenance Protocols

Throttle linkage return springs must exert 4 lbs pull force to guarantee positive mechanical throttle closure. Do not drop this commercial replacement engine into high displacement pickup chassis or stationary woodchippers lacking radiator shrouds. Maintenance crews must carry out essential shop preventive routines.

• Perform break-in oil drainage and filter changeout at 500 miles or 20 operating hours.
• Verify rocker arm pivot torque values match 18 ft-lbs during post run inspection checks.
• 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.
