VEGE Remanufactured DA07 4.2L 258ci Premium Grade Long Block Engine

Description

Persistent oil leaks along two-piece rear main seals and flat tappet camshaft lobe rounding cripple classic utility four-wheelers. The VEGE Remanufactured DA07 Premium Grade Long Block Engine cures internal oil starvation during a commercial long block repower overhaul. This 4.2L 258ci 6-Cylinder inline pushrod motor outputs 115HP. Mechanics must verify distributor drive gear tooth engagement depth before installation.

Rugged ASTM A48 Class 30 gray iron forms the heavy inline cylinder block and overhead valve combustion head. A precision balanced nodular iron crankshaft turns inside tri-metal bearings inside this VEGE engine build. Cranking starter draw pulls 145A across standard 12V electrical systems during cold winter ignition. Package unrigged dry weight reaches 440 lbs across dimensions of 33in length, 20in width, 26in height. The stamped steel sump holds 5.0 quarts.

Key Features of VEGE Remanufactured DA07

Shop managers buy VEGE Remanufactured DA07 Premium Grade Long Block Engine units to power vintage utility fleet vehicles. Every industrial engine rebuild pairs upgraded valvetrain components with resurfaced iron heads to deliver dependable pulling torque under tough route conditions.

• Heavy duty flat tappet camshafts deliver high low-end torque profiles tuned for utility work.
• 0.0014in connecting rod journal clearances provide continuous hydrodynamic oil cushioning during slow crawling.
• Upgraded silicone rear main seals eliminate chronic oil drips behind the flywheel mounting flange.
• The DA07 commercial core features induction hardened exhaust valve seats for unleaded fuel durability.
• Plateau honed cylinder walls allow cast iron rings to seat fast without bore scuffing.
• Double roller timing chains eliminate camshaft timing slack across thousands of hard work hours.
• Precision ground steel pushrods maintain structural rigidity during sudden transmission downshift events.

Continuous Load Dynamometer Ratings

Shop dynamometer sweeps measure this DA07 long block engine at 115 BHP and 210 ft-lbs of gross torque at 2400 RPM continuous test loading. Main gallery oil pressures register 45 PSI at 190°F oil pan thermal stabilization. Exhaust runner probes reach 1180°F during sustained continuous test runs on the water brake absorber unit. Dynamic compression testing displays 165 PSI across all six cylinders within 4% balance across the block. Crankshaft center journal runout measures under 0.0002in TIR to avoid bearing babbit wear under load.

Field Usability Shop Guidelines

Carburetor or throttle body linkages require 4 lbs of return tension for crisp throttle return. This 4.2L inline six pushrod engine is NOT engineered for high RPM circle track racing, overhead cam computerized platforms, or marine inboard pleasure hulls.

• Dump initial break-in mineral oil alongside the spin-on filter at 500 miles or 30 engine hours using high zinc oil.
• Adjust hydraulic flat tappet rocker pivot bridge bolts to 19 ft-lbs during cold bench pre-assembly setup.
• Retorque cylinder head bolts in proper circular progression sequence following initial thermal warm up cycles.
