Case TX170-45 Telehandler: Heavy-Duty Telescopic Handler

The Case TX170-45 is the heavy-duty member of the Case Telehandler line - 17,000 lb (TX170) class load capacity paired with 45-ft boom reach in the TX170-45 designation. Built for agriculture, construction, and industrial applications where reach and lift capacity beat compact telehandlers, the TX170-45 is the right tool when a hub-class telescopic handler is what the job demands.

Where the TX170-45 fits in the Case telehandler line

The Case TX170-45 is the heavy-duty member of the Case Telehandler family - sitting above compact siblings like the TX742 in both lift capacity and reach. 17,000 lb class load capability paired with 45-ft boom extension puts the TX170-45 into the working envelope that handles feed bunk filling, second-floor framing, stacked yard storage, and industrial material handling jobs that smaller telehandlers cannot reach.

The TX170 platform was engineered for high-cycle production on ag, construction, and industrial sites where reach and lift capacity together are non-negotiable. The -45 designation specifies the 45-ft maximum boom extension - the long-reach variant within the TX170 family.

Engine, transmission, and boom hydraulics

The TX170-45 runs a turbocharged diesel through a powershift transmission into a 4WD driveline with selectable 2WS, 4WS, and crab steering modes. The multi-stage telescopic boom carries the load through a multi-stage extension cylinder and a heavy-class lift cylinder; a tilt cylinder controls fork angle at the carriage. Stabilizer outriggers (where equipped) extend lateral reach beyond what wheel-only stability allows.

The boom, chassis, axles, and hydraulic components on the TX170-45 are heavier class throughout than what you find on the compact TX-series telehandlers - this is the production-grade end of the Case telehandler line, engineered to lift and reach near the upper limit of what a wheeled telescopic handler can do.

Common service items on the TX170-45

• Engine internals: Turbocharged diesel pistons, rings, sleeves, bearings, head gaskets - full overhaul kits matched to the production engine.
• Cooling system: Radiator, water pump, thermostat, fan, hoses, belts, charge-air cooler, hydraulic oil cooler.
• Powershift transmission: Heavy-class powershift clutch packs, transmission filters and oil, torque converter service.
• Drivetrain - axles: 4WD front and rear axle service, planetary final drives, driveshafts, steering joints - all heavy-class.
• Boom hydraulics: Multi-stage extension cylinder, heavy-class lift cylinder, tilt cylinder seal kits. Multi-stage cylinder service is more involved than single-stage.
• Boom wear pads: Multi-section wear pads (side, top, bottom on each boom stage). High-volume wear-pad service on a multi-stage boom - inspect routinely.
• Carriage / forks: Heavy-class quick-attach carriage hardware, fork tine wear, fork retention pins, side-shift carriage option service.
• Stabilizer outriggers: Outrigger cylinder seal kits, outrigger pivot pins and bushings, outrigger pad replacement.
• Steering: Steering valve with mode selection (2WS / 4WS / crab), steering cylinder seal kits, mode actuator valve.
• Brakes: Heavy-class wet-disc service brakes, brake oil filters, park brake actuation.
• Cab and electrical: Cab HVAC, ECU, instrument cluster, sensors, wiring harness, alternator, starter, mirror assemblies.

Parts we carry for the Case TX170-45

What to verify before ordering

• Serial number. Confirm the serial on the chassis rail or cab data plate before ordering year-specific boom or transmission parts.
• Engine serial. Turbo diesel internal parts are calibrated to specific engine serial groups.
• Boom-section wear-pad position. Multi-stage boom has multiple wear-pad positions on each section - confirm boom section, position (side / top / bottom), and current pad thickness before ordering.
• Multi-stage extension cylinder. Multi-stage boom extension cylinders have multiple seal positions; confirm bore, rod diameter, and which stage needs service.
• Stabilizer outrigger equipped. Not all TX170-45 units have stabilizer outriggers - confirm before ordering outrigger-specific seal kits or pivot hardware.
• Side-shift carriage option. Side-shift carriage is an option - confirm whether the unit is side-shift equipped before ordering carriage service parts.

Why the TX170-45 still earns a paycheck

The Case TX170-45 stays in service because heavy-class telehandlers with long reach do work that nothing else can - feed bunk filling on ag operations, second-floor framing on residential and light commercial construction, stacked yard storage, industrial material handling. 17,000 lb capacity with 45-ft reach covers the working envelope that makes this category of machine indispensable on the right job site.

Maintenance priorities on a TX170-45: clean fuel and quality filtration for the turbo diesel, powershift transmission oil quality, boom-wear-pad inspection on every boom section (multi-stage means more wear points), boom hydraulic cylinder seals (multi-stage extension is a higher-service item than single-stage), stabilizer outrigger pivot lubrication and seal condition where equipped, and steering-mode valve health.
