Rear main crankshaft seal seepage and plastic valve cover warping cause chronic oil loss across older work trucks. The VEGE Remanufactured DA21 4.2L 258ci High Output Long Block Engine terminates crankcase oil drip throughout this commercial long block repower. This 6-Cylinder 130HP inline engine demands careful distributor gear tooth mesh alignment during initial static ignition timing.

ASTM A48 Class 30 dense gray iron forms both the long-block inline crankcase and 12-valve cylinder head. A heavy cast nodular iron 3.895in stroke crankshaft spins within copper-lead tri-metal bearings inside line-honed main webs. This VEGE engine core requires a 12V 155A starter draw under cold crank conditions. Dry weight reaches 440 lbs, spanning a 34in length, 20in width, 26in height stance with 5.0 quarts oil capacity.

Key Features of VEGE Remanufactured DA21

Field mechanics buy VEGE Remanufactured DA21 High Output Long Block Engine packages to keep municipal utility fleets moving. Every industrial engine rebuild receives diamond line-bored main bearing saddles to preserve crankshaft oil film under heavy low-RPM pulling.

- Cylinder bores measure 3.750in with diamond plateau honed surface finishes.
- Main journal oil clearance holds at 0.0015in across all seven main bearings.
- Viton dual-lip rear main seals prevent persistent flywheel housing oil leaks.
- Induction-hardened cast iron camshaft lobes resist flat-tappet lifter wear.
- Multi layer steel cylinder head gaskets maintain combustion seal across long decks.
- This DA21 commercial core features cylinder head deck resurfacing flat to 0.0003in.
- Heavy-duty pushrods maintain true concentricity under full spring compression loads.

Dynamometer Load Station Records

Automated brake cell test records certify that this DA21 long block engine generates 130 continuous BHP and 210 ft-lbs of torque at 2400 continuous load RPM. Internal oil gallery pressure measures 50 PSI while oil sump temp levels at 190°F under sustained brake loads. Exhaust gas temp stabilizes at 1200°F down the test manifold runner. Cylinder compression registers between 165 PSI and 172 PSI across all six cylinders. Crankshaft center journal runout holds within 0.0003in TIR.

Chassis Placement Excluded Usages

Carburetor throttle linkage return springs need 5 lbs of pull force to ensure positive idle drop. This long-stroke inline motor is not engineered for high-RPM circle track racing, marine inboard use, or stationary sawmill saw drives.

- Drain break-in motor oil and replace filter element after 500 miles or 25 operating hours.
- Inspect non-adjustable hydraulic lifter preload between 0.020in and 0.060in cold.
- Torque cylinder head fasteners to 85 ft-lbs in three successive rotational stages.

Commercial Protection Crate Manifest

Certified under the VEGE assembly standard, this engine carries a 3-Year 100,000-mile parts protection warranty. Each wood shipping container houses the remanufactured long block core, steel oil pan, front timing cover, stamped valve cover, oil pickup tube, and signed dyno load sheet.
