VEGE Remanufactured DC93 2.8L 173ci Heavy Duty Long Block Engine

Description

Crankshaft journal scoring under continuous cargo hauling and rocker stud pullout cease after installing the VEGE Remanufactured DC93 2.8L Long Block Engine. Generating 130HP from a 173ci 6-Cylinder commercial long block repower layout, this unit powers commercial fleet haulers. Installers must confirm rocker arm stud thread engagement depth in cylinder heads before setting final valve lash.

Dense ASTM A48 Class 35 gray iron forms the engine block, delivering massive structural strength to counter thermal bending under continuous delivery routes. The VEGE engine core utilizes induction-hardened nodular iron camshaft lobes paired with stellite-faced valves. Cranking starter demand requires 12V 150A. Engine dry weight measures 330 lbs inside a 22in length, 22in width, 24in height chassis envelope holding 4.5 quarts oil.

Key Features of VEGE DC93

Municipal highway maintenance fleets buy VEGE DC93 commercial long block configurations to eliminate recurring bottom-end bearing scuffing. Modern clean-room shops enforce verified industrial engine rebuild benchmarks throughout each production cycle.

• Cast nodular iron crankshaft features micro-polished journal surfaces with 0.0003in TIR runout tolerance.
• Threaded rocker arm studs replace pressed studs to eliminate thread pullout under high RPM cycles.
• Centrifugally cast iron cylinder walls receive fine diamond plateau honing for extended ring life.
• CNC milled deck surfaces ensure 0.0002in flatness to stop high-pressure cylinder head fire-ring blowby.
• High-volume internal oil pump maintains 50 PSI line pressure across demanding fleet highway duty.
• DC93 commercial core architecture incorporates reinforced main bearing web bulkheads for crankcase rigidity.
• Tri-metal copper-lead bearings establish 0.0014in running clearance to protect crank journals from wear.

Dynamometer Test Bench Load Limits

Dynamometer load trials verify 130 continuous BHP alongside 155 ft-lbs torque output at 4600 RPM continuous operational rating. Galley pressure maintains 50 PSI at 190°F oil sump temperature, while exhaust gas temp levels off at 1200°F during dyno load. Bench sensors record 180 PSI compression across all six cylinders within 3% balance. Crankshaft runout checks at 0.0003in TIR on the DC93 long block engine.

Installation Requirements Negative Filter Rules

Throttle spool return resistance measures 4 lbs force on the bracket return spring. This powertrain is NOT manufactured for marine salt-water inboard applications or heavy rear-wheel-drive commercial chassis. Plant technicians must execute these scheduled service steps without exception.

• Drain break-in engine oil reservoir and replace oil filter at 500 miles or 30 hours.
• Set hydraulic roller lifter preload depth between 0.030in and 0.040in before valve cover installation.
• Check lower intake manifold retention bolts after the initial two operating cycles.

Warranty Statement Shipping Pallet Inventory

All rebuilding procedures meet strict VEGE assembly standard metrics covered by a 3-Year 100,000-mile warranty. The wood transport container houses the long block core, stamped oil pan, aluminum front cover, stamped valve covers, oil pickup tube, and signed dyno run verification sheet.
