Case 330B Articulated Dump Truck: B-Series 6x6 Heavy-Haul ADT
The Case 330B Articulated Dump Truck is a heavy-haul 6x6 ADT for high-volume earthmoving, mining edge, and large-scale construction. B-series refinement of the original 330 platform — Cummins diesel, ZF planetary transmission, fully articulated chassis with rear bogie.
Where the 330B fits in the Case articulated dump truck line
The Case 330B is the B-series refinement of the 330 platform — heavy-haul 6x6 ADT alongside the larger 340 in Case’s articulated dump truck range. ~30-ton payload class with the durable articulated chassis, rear bogie, and powerful diesel that the segment demands.

Engine, hydraulics, and drivetrain
The 330B runs a Cummins heavy-duty diesel through a ZF planetary automatic transmission into a 6x6 drivetrain with a front axle and a rear bogie (two driven rear axles). Articulated chassis pivots between the front truck and the rear bogie / dump body. Hoist hydraulics raise the dump body. The 845255 radiator is a direct-fit Case 330B service item.
Common service items on the 330B
- Engine internals: Cummins heavy-duty diesel pistons, rings, sleeves, bearings, head gaskets, full overhaul kits.
- Cooling system: 845255 radiator is the direct-fit Case 330B Articulated Truck radiator. Water pump, thermostat, fan, hoses, belts, charge-air cooler.
- Transmission: ZF planetary clutch packs, transmission filters and oil, torque converter service.
- Drivetrain / axles: Front axle, rear bogie axles, planetary final drives, driveshafts, U-joints. 8603527 axle cover O-ring cross-fits Case 521–1021 loaders and 325–330B trucks.
- Hoist hydraulics: Dump body hoist cylinder seal kits, hoist pump rebuild, control valve service, hoses.
- Articulation: Front-to-rear articulation pivot pins, bushings, steering cylinder seal kits.
- Brakes: Wet-disc heavy service brakes with retarder service. 8603163 brake pin cross-fits Case 521–921 wheel loaders and 335–340B ADTs (broad Case brake-pin cross-fit).
- Tires + wheels: Heavy off-highway radials, rim and wheel-bearing service.
- Cab and electrical: Cab HVAC, ECU, instrument cluster, sensors, wiring harness, telematics module.

Call our parts team with your serial number — we’ll match the right component to your machine.
Request a PartWhat to verify before ordering
- Serial number. Confirm the serial on the frame near the front articulation pivot before ordering year-specific parts.
- Engine serial. Cummins engine internal and aftertreatment parts are calibrated to specific engine serials.
- ZF transmission revision. ZF planetary transmissions saw revisions during production — confirm by serial before ordering clutch-pack components.
- Axle generation. 8603527 axle O-ring fits Case 521–1021 loaders + 325–330B ADTs — confirm front vs. rear bogie axle position before ordering.
- Brake pin specification. 8603163 brake pin cross-fits a broad Case range — confirm pin position and brake-pack revision.
Why the 330B still earns a paycheck
The Case 330B is the production-class B-series articulated dump truck for high-volume earthmoving operations — quarries, large construction sites, mining-edge, and any application where on-highway dump trucks can’t handle the terrain and rigid-frame trucks can’t handle the cycle-time turn-around. 6x6 articulation gives soft-ground capability that wheeled trucks don’t have.
Maintenance priorities on a 330B: clean fuel and quality filtration on the Cummins diesel, ZF transmission oil quality, hoist hydraulic system condition, articulation pivot lubrication, brake pin service (8603163 cross-fit), and the 845255 radiator service interval. Broken Tractor maintains parts coverage across the Case ADT line.
