VEGE Remanufactured DCD4 3.1L 189ci Heavy Duty Long Block Engine

Description

A 3135cc displacement baseline powers the VEGE DCD4 Heavy Duty Long Block Engine during critical commercial long block repower projects. This 3.1L 189ci 6-Cylinder unit generates 140HP for municipal service fleets. Field mechanics must inspect front accessory bracket mounting bolt thread pitch because metric and imperial castings vary across model vehicle production years.

Solid ASTM A48 gray iron forms the deep skirt engine block for rigid crankshaft support under transit stress. Every VEGE engine core incorporates a balanced nodular iron crankshaft and heat treated forged steel connecting rods. Premium silicon aluminum pistons transfer heat into the cooling jacket. The 12V starter motor pulls 150A during cold engine testing. Total unrigged weight registers 340 lbs within space constraints of 24in length, 22in width, 23in height with 4.0 quarts oil capacity.

Key Features of VEGE DCD4

Fleet supervisors buy VEGE DCD4 Heavy Duty Long Block Engine setups to finalize an industrial engine rebuild without costly machine shop delays. Strict robotic boring centers each cylinder axis perpendicular to the main bearing centerline for maximum piston ring seal.

• A compact 60-degree V6 block architecture fits tight transverse and longitudinal commercial chassis bays.
• Micro polished rod journals reduce friction to maintain 0.0012in hydrodynamic oil film thickness.
• Heat treated valvetrain pushrods resist deflection during rapid engine deceleration cycles.
• The DCD4 commercial core cylinder heads receive vacuum decay testing to prove zero port valve leakage.
• Multi layer steel head gaskets eliminate coolant leaks around lower intake coolant crossover ports.
• High strength main cap bolts hold bearing shells in true circular geometry under high load.
• A balanced dampener hub absorbs torsional crankshaft vibrations across all road speeds.

Dynamometer Verification Operational Thresholds

Dyno load cell testing proves that each DCD4 long block engine delivers 140HP and 180 ft-lbs of shaft torque at 3,600 RPM. Testers subject the assembly to continuous 2,000 RPM operation while oil gallery pressure stays firm between 42 PSI and 58 PSI. Engine oil sump temperature reads 188°F and exhaust gas heat levels peak at 1,150°F. Dynamic compression checks show 170 PSI across all six cylinders with variance under 4%. Crankshaft journal runout measures 0.0002in TIR to ensure minimum bearing friction.

Field Installation Maintenance Protocols

Accelerator cable brackets must yield 4 lbs pull force to guarantee immediate throttle plate closure. Do not install this commercial replacement engine into high performance forced induction race cars or industrial stationary woodchippers lacking radiator fans. Plant mechanics must apply standard shop preventive care steps.

• Flush and replace the initial engine break-in oil and spin-on filter after 500 miles or 20 hours.
• Verify rocker arm pivot torque values match 18 ft-lbs during post run inspection checks.
• Check ignition timing marks with a diagnostic strobe light to confirm base advance at 10° BTDC.

Crate Manifest Coverage Terms

Production matches the strict VEGE assembly standard supported 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 pump pickup screen, and the bench inspection sign-off document.
