VEGE Remanufactured DDH1 3.7L 226ci Heavy Duty Long Block Engine

Description

A 226 cid displacement baseline defines the VEGE DDH1 Long Block Engine, built to conquer heavy commercial long block repower demands in municipal fleet vehicles. This 3.7L PowerTech V6 produces 210HP at 5,200 RPM and 235 ft-lbs torque. Technicians must check cylinder head casting revision codes because combustion chamber volumes changed across model years.

Solid ASTM A48 Class 30 gray iron forms the deep skirt V6 block casting. A precision ground nodular iron crankshaft pairs with powdered metal connecting rods inside this VEGE engine core. Starter draw measures 150A on 12V shop circuits. Dry weight scales at 395 lbs across dimensions measuring 25in length by 25in width by 27in height. Sump holds 5.0 quarts.

Key Features of VEGE DDH1

Fleet repair facilities buy VEGE DDH1 Long Block Engine packages to avoid machine shop queues during an industrial engine rebuild turnaround. Remanufacturing operations install new lifters and lash adjusters to ensure quiet valvetrain operation.

• Combustion chamber designs promote rapid flame propagation to eliminate low speed spark knock.
• Single overhead camshafts reduce valvetrain reciprocating mass to minimize parasitic drag.
• Coated piston skirts prevent cylinder wall galling under high thermal engine loads.
• The DDH1 commercial core maintains 0.0015in main journal bearing clearances for steady oil film retention.
• A heavy duty dual chain timing set maintains precise camshaft timing events over extended run times.
• Cross bolted main bearing caps lock the rotating assembly into the rigid bottom end cradle.
• Multi layer steel head gaskets seal high combustion pressures against block deck faces.

Dynamometer Bench Validation Load Ratings

Dynamometer testing confirms 210HP at 5,200 RPM plus 235 ft-lbs torque at 4,000 RPM for this DDH1 long block engine. Pressure sensors track 50 PSI oil gallery pressure at 2,000 RPM while maintaining 195°F coolant operating temperature. Combustion chamber compression balances at 175 PSI per bore with variance below 3%. Crankshaft journal runout measures 0.0002in TIR. Exhaust collector pyrometers record 1,220°F during full load pulls.

Field Installation Preventative Maintenance Directives

Drive by wire throttle actuators demand unbent electrical terminal pins during harness mating. Fleet mechanics must avoid this commercial replacement engine for vintage non-OBD2 platforms or conversions without factory computer controlled ignition timing.

• Replace initial break in oil after 500 miles or 30 run hours then install fresh 5W-30 motor oil.
• Inspect oil pickup tube screen seating to prevent oil aeration under high engine RPM sweeps.
• Retorque cylinder head bolts in three progressive stages reaching 90 ft-lbs final setting.

Crate Manifest Warranty Protection Coverage

Supported by the VEGE build standard, this long block includes a 3-Year or 100,000-mile manufacturer warranty. The rugged wooden crate contains the remanufactured long block core, oil pan, timing cover, valve covers, oil pump pickup tube, plus certified dyno inspection paperwork.
