Case IH 2470, 2670 Tractor Service Pdf Manual (Serial No. 8762940 & Later)

Case IH 2470, 2670 Tractor Service PDF Manual (Serial No. 8762940 & Later)

Built for large-scale tillage, land preparation, and heavy drawbar applications, the Case IH 2470 and 2670 articulated four-wheel-drive tractors were engineered to deliver exceptional traction and dependable power in demanding field conditions. Their unique chassis design, heavy-duty powertrain, and high-capacity hydraulic system made them ideal for pulling large cultivators, chisel plows, discs, and air seeders across extensive acreage. This OEM Factory Service PDF Manual, covering 2470 tractors from Serial No. 8762940 and later and 2670 tractors from Serial No. 8763224 and later, provides the complete dealership workshop procedures required to diagnose, repair, overhaul, and restore these powerful machines to factory operating standards.

Rather than simply explaining routine maintenance, this factory manual walks technicians through systematic troubleshooting and complete component rebuilding. Whether repairing the RPS-34 powershift transmission, rebuilding the 504-series diesel engine, servicing the articulated steering system, or restoring hydraulic performance after years of heavy field work, every procedure follows original Case workshop specifications supported by detailed illustrations, hydraulic schematics, electrical wiring diagrams, inspection limits, and adjustment data.

Engineered for High-Draft Agricultural Operations

The 2470 and 2670 belong to the renowned Case articulated four-wheel-drive tractor family, developed for producers requiring maximum pulling power with excellent flotation and traction. These tractors feature a turbocharged 504 cubic-inch six-cylinder diesel engine, articulated 4WD steering, heavy-duty planetary final drives, an RPS-34 partial powershift transmission, and a high-capacity hydraulic system capable of operating today's demanding tillage and seeding equipment. Gross engine output ranges from approximately 213 HP on the 2470 to 256 HP on the 2670, making them among the most capable field tractors of their era.
