The Legacy of the Case 580 Super E
The Case 580 Super E was introduced in the early 1980s as part of Case Corporation’s long-standing 580 series, which began in the 1960s and became one of the most widely recognized backhoe loader lines in North America. The Super E model marked a significant upgrade over its predecessors, offering improved hydraulic performance, enhanced operator comfort, and a more robust drivetrain. With a diesel engine producing around 60 horsepower and a digging depth exceeding 14 feet, the 580SE was designed for versatility in construction, agriculture, and utility work.
Case Corporation, founded in 1842 and later merged into CNH Industrial, has built a reputation for durable and serviceable equipment. By the mid-1980s, Case had sold hundreds of thousands of backhoe loaders globally, with the 580 series accounting for a large portion of that success. The Super E model, in particular, became a favorite among small contractors and municipalities due to its reliability and ease of maintenance.
Initial Condition and Assessment
The restoration project began with the acquisition of a 580SE in visibly rough condition. The machine exhibited multiple hydraulic leaks, a large weld repair on the boom tower, and a host of missing or damaged components. The most urgent issue was the inability of the boom and dipper cylinders to hold pressure, causing the backhoe arm to collapse within seconds of activation.
Other notable problems included:
The hydraulic system required immediate attention. The dipper cylinder was outsourced to a mobile hydraulic technician, while the boom cylinders were rebuilt on-site. Seal kits were sourced from reputable suppliers, with prices ranging from $20 to $25 per cylinder. The process involved:
Torque Converter and Drain Plug Mystery
A missing drain plug initially raised concerns about fluid loss and internal damage. However, experienced mechanics clarified that the torque converter housing on dry systems is vented and does not require fluid. The plug hole is designed for access during maintenance and can be sealed to prevent debris intrusion. The thread size was estimated to be ½" or ¾" NPT.
Braking System and Parking Brake Clarification
The grabby brakes were attributed to improper fluid or contamination. It was emphasized that the brake master cylinders should be topped with the correct hydraulic fluid, not standard brake fluid, to avoid seal degradation. The broken bracket on the transmission was identified as part of the parking brake assembly, which had been bypassed by using the outriggers as a makeshift brake.
Electrical and Instrumentation Repairs
The tachometer and hour meter were non-functional, likely due to a failed sensor or broken wiring. These components are essential for tracking maintenance intervals and engine performance. Replacement parts were sourced from Case’s online catalog, which had become more accessible in recent years.
Structural and Cosmetic Fixes
The boom tower had a previous weld repair, which was inspected for integrity. A missing engine shroud was noted, with advice to monitor coolant temperature closely until a replacement could be fabricated. A bent pad bracket and broken cotter pins were repaired using proper hardware, replacing improvised solutions like nails and tack welds.
Operator Experience and Learning Curve
The owner, new to backhoe operation, quickly adapted to the controls and spatial awareness required for digging. After years of using a mini-excavator, the transition to a full-size backhoe offered increased capability and reduced manual labor. The first digging session revealed the machine’s potential, despite its initial flaws.
Environmental Considerations and Improvisation
To prevent hydraulic fluid from contaminating the soil, especially on properties with well water, a drip chute was constructed from salvaged fluorescent light reflectors. This creative solution demonstrated the importance of environmental responsibility in equipment maintenance.
Advice for Cylinder Removal and Rebuild
For those tackling similar projects, the following tips were shared:
Restoring a Case 580 Super E is a rewarding endeavor that combines mechanical skill, resourcefulness, and historical appreciation. Despite its age and wear, the 580SE remains a capable machine with a strong support network and readily available parts. With careful attention to hydraulics, structure, and safety, this backhoe loader can return to productive service and continue its legacy in the field. The project serves as a testament to the enduring value of well-built equipment and the satisfaction of hands-on restoration.

The most urgent issue was the inability of the boom and dipper cylinders to hold pressure, causing the backhoe arm to collapse within seconds of activation.
Other notable problems included:
- Poor hydraulic line routing and missing clamps
- A missing drain plug on the torque converter housing
- A smashed oil pan and questionable oil pickup integrity
- Grabby brakes and missing auto-leveling linkage
- Non-functional tachometer and hour meter
- Broken pin retainers and a missing boom lock pin
- Damaged differential bracket and conversion from 4WD to 2WD
The hydraulic system required immediate attention. The dipper cylinder was outsourced to a mobile hydraulic technician, while the boom cylinders were rebuilt on-site. Seal kits were sourced from reputable suppliers, with prices ranging from $20 to $25 per cylinder. The process involved:
- Removing cylinders using a shop crane
- Draining fluid with a custom-made drip chute to protect groundwater
- Disassembling cylinders with breaker bars and gland wrenches
- Peening the cylinder ends with a hammer to loosen stubborn glands
- Replacing seals and reassembling with care to avoid scoring

Advice for Cylinder Removal and Rebuild
For those tackling similar projects, the following tips were shared:
- Use a cherry picker or compact tractor to lift heavy cylinders
- Dig a trench to lower the boom for easier access
- Leave the cylinder tube mounted and remove only the rod when possible
- Expect to lose several gallons of fluid during disassembly
- Budget two hours for the first cylinder, with faster times on subsequent units
