Case 521F Wheel Loader Meets T4-F

February 25, 2016

The Case Construction Equipment 521F wheel loader is available with a standard Z-bar linkage for large operating loads, an XR linkage for extended reach and dump clearance, and a tool-carrier XT linkage for versatility and parallel lift.

It meets EPA Tier 4-Final emissions standards using SCR technology with a Fiat Powertrain engine that provides 131 net peak horsepower.

Case 521F Wheel Loader Specifications

  • Engine: Fiat Powertrain
  • Horsepower: 131
  • Operating weight: 22,948 pounds
  • Bucket breakout: 19,303 pounds
  • Bucket capacity: 2.3 cubic yards

Case says the SCR technology allows the machine to handle inconsistent engine loads while running at peak performance without compromising power. This is accomplished with a faster throttle response and acceleration, all while maintaining lower exhaust temperatures and improving fuel efficiency over machines using EGR technology and a DPF.

Additional fuel savings are achieved with a standard auto-idle feature that helps minimize excessive fuel burn during operator inactivity by further lowering engine rpm. Standard auto shutdown then shuts down the engine after an operator-selected length of time to further preserve fuel.

The SCR-only approach found on the new 521F also contributes to machine uptime, the company says, by eliminating the need for manual DPF regeneration and the associated downtime that can occur with wheel loaders that use EGR.

Additionally, SCR results in extended time between service intervals, as lower ambient exhaust temperatures result in slower degradation of engine components and less demand on the coolant system.

Spec-wise, the 22,948-pound wheel loader has a bucket breakout force of 19,303 pounds with 2.3-cubic-yard bucket capacity. The 521F is the smallest Case loader not considered part of its compact line.

Limited-slip axles for traction on slippery or uneven surfaces are standard, and optional heavy-duty axles with locking front differential are available to reduce tire wear when operating on hard surfaces. A wide variety of tires is also available, including snow tires.

Buckets for the 521F can be equipped with the optional SmartFit bucket tooth system. These heavy-duty self-sharpening teeth are installed with a hammerless fastener system and reusable locking pins.

An expanded selection of attachments include new buckets, rotary brooms and forks.

The Case Quiet Cab has a dual air filtration system, optional heated air-ride seat, and insulated cab mounts. Floor-to-ceiling windows, an improved lighting system, and optional rearview camera team to provide enhanced visibility.

The wheel loader also features a joystick steering option and an Advanced Instrument Cluster with four selectable power modes (Economy, Standard, Max and Auto).

Case’s mid-mounted cooling system is configured like a cube with all coolers facing fresh and cool ambient air. This improves the effectiveness and efficiency of the cooling system, according to the company, and also makes it easier to clean. The design moves the engine lower and more to the rear of the wheel loader, improving balance and access to daily service points.

Ground-level fluid gauges and a tilt-up rear hood complete the serviceability package. The 521F is covered under Case ProCare heavy machine support program. ProCare features a suite of product assurances that include a three-year Advanced Case SiteWatch telematics subscription, a three-year/3,000-hour full-machine factory warranty, and a three-year/3,000-hour planned maintenance contract.
