Important Compatibility Notes
DI and CR Fuel Systems Are Different: V2607-DI and V2607-DI-T use mechanical direct injection, while V2607-CR-E4 and V2607-CR-E5B use electronic common rail. These systems do not share pumps, injectors, ECU, or harness components.
Multiple Output Ratings: Output varies from ~36 kW (V2607-DI-T-ET22e) to 49.2 kW (V2607-T). Different calibrations serve various machines and emission tiers identified by ET09e, ET21, ET22e, EW08M, E3B, E4, and E5B codes.
Cat C2.6 Equivalence: The Cat C2.6 shares identical 2.615L displacement and 87 x 110 mm specifications with the V2607, cross-referenced as part number 380-1781 for Cat 307 machines.
V-Series Engine Range: The V2 and V3 series includes six displacements (V1505 1.5L, V2203 2.2L, V2403 2.4L, V2607 2.615L, V3300/V3307 3.3L, V3600/V3800 3.8L). These engines do not interchange despite appearing in combined listings.
Product Core Advantages
- Mechanical DI and electronic CR builds clearly separated
- Four distinct output ratings matched to specific build codes
- Cat C2.6 equivalence properly identified from machine plates
- Clear condition tier declaration - new, reconditioned, or used
