Case 580 Super N Backhoe Loader: Specs, Parts & Common Issues
Produced 2008 – present, the 580 Super N is the turbocharged N-generation Construction King — the current top-of-line small-frame Case backhoe loader. FPT NEF F4HE 4.5L Tier 3 at launch, transitioning through Tier 4 Interim (DPF + EGR) to Tier 4 Final F5BFL413C 3.4L (SCR + DEF). Wide-Track (WT) variant adds rear-end width and stabilizer reach. 61 verified service parts in our inventory across the Super N family.
The Case 580 Super N is the turbocharged version of the current-generation Construction King small-frame backhoe loader. It came to market in 2008 alongside the naturally aspirated 580N and continues in production today. The Super N runs FPT-family industrial diesels across three emissions tiers: Tier 3 (2008–~2011) with the FPT NEF F4HE9484 4.5L Common-Rail turbo, Tier 4 Interim (~2011–2014) with DPF and EGR added to the F4HE, and Tier 4 Final (2014–present) with the FPT F5BFL413C 3.4L paired with SCR and DEF. A Wide-Track (WT) variant runs alongside the standard machine, distinguished by a wider rear-end configuration that increases stability under heavy lifts.
For owners maintaining a 580 Super N today, the parts ecosystem is exceptionally deep. Top-volume service categories: stabilizer cylinders (the 84259227 stabilizer cylinder seal kit and 84421606 stabilizer cylinder), swing-tower pins and bushings (the 84326988 swing-tower-at-boom bushing and 84235607 swing-tower-at-frame bushing), and bucket and quick-coupler hardware (the 84229979 bucket quick coupler and 84223653 quick coupler pin).

Tier 3 → Tier 4 Interim → Tier 4 Final progression
The 580 Super N's most consequential parts-ordering fact is the emissions tier configuration:
- Tier 3 (2008 – ~2011) — FPT NEF F4HE9484 4.5L Common-Rail turbo. Same engine family that arrived on the 580 Super M Series III in 2008. No DPF, no SCR. Passive oxidation catalyst on the exhaust.
- Tier 4 Interim (~2011 – 2014) — F4HE 4.5L with cooled EGR plus DPF. Periodic active regeneration required. New ECU and harness. The CS-590SM-II-FK filter kit (labeled "Turbo Iveco") covers Tier 4 Interim Super N and 590 Super M machines.
- Tier 4 Final (2014 – present) — FPT F5BFL413C 3.4L Common-Rail with SCR and DEF injection. DEF tank, dosing module, and SCR catalyst all introduced as new service items. Displacement drops from 4.5L to 3.4L but power is maintained through higher injection pressures.
Identifying tier visually: short straight stack with muffler only = Tier 3; large DPF canister behind cab = Tier 4 Interim; separate DEF tank (blue-cap) plus SCR mixing hardware = Tier 4 Final.
How the 580 Super N differs from the 580N
The Super N and 580N share their chassis, transmission base architecture, axles, brakes, hydraulics, cab, and most loader and backhoe iron. Most service parts cross-fit cleanly between the two. The differences:
- Engine — Super N uses turbocharged variants; 580N uses naturally aspirated versions of the same FPT engines.
- Power output — Super N approximately 90–97 HP net; 580N approximately 79–88 HP net.
- Turbocharger — only on the Super N.
- Stabilizer cylinder — Super N uses the 84421606 stabilizer cylinder (Super N-specific casting). The 580N uses the 84421604 stabilizer cylinder. Different part numbers — confirm machine variant before ordering.
- Loader bucket tilt cylinder — Super N (including WT) uses the 91708357 loader bucket tilt cylinder. The 580N uses 84421600 rebuilt.
- Filter kits — turbo-specific filtration on the Super N.
Many chassis and hydraulic items cross. Pins, bushings, swing-tower hardware, cab glass — most of the high-volume parts label "580N, 580SN" because they fit both.
Wide-Track (WT) variant
The 580 Super N WT is the wide-track version of the Super N — same engine, transmission, cab, hydraulics, and loader iron as the standard Super N, but with a wider rear-end configuration that increases stability under heavy lifts and provides more stabilizer reach. Most parts cross between standard and WT, but a handful are WT-specific.
The 84159675 extension cylinder covers both 580SN and 580SN WT plus 580N EP and 580N. The 84259228 stabilizer cylinder seal kit is explicitly labeled for 580SN WT (and 590SN), making it the WT-specific seal kit.
FPT engine families on the Super N
The FPT NEF F4HE9484 4.5L Tier 3 launch engine carries forward from the 580 Super M Series III. Common-Rail Bosch injection, electronic engine management, four-cylinder direct-injection diesel. The Tier 4 Interim version adds cooled EGR and a Diesel Particulate Filter for emissions compliance — same engine block with after-treatment additions.
The FPT F5BFL413C 3.4L Tier 4 Final engine is a smaller-displacement four-cylinder paired with SCR (Selective Catalytic Reduction) and DEF (Diesel Exhaust Fluid) injection. Power output is maintained through higher injection pressures and more efficient combustion despite the displacement drop. This is the engine on current-production Super Ns.

Common issues and what to expect
Tier 4 after-treatment service
The Tier 4 Interim DPF and Tier 4 Final SCR + DEF systems are the most common sources of service complaints on Super N machines. DPF active-regeneration faults, DEF dosing module failures, NOx sensor faults, and SCR catalyst monitoring faults are all routine items. Most can be cleared with dealer service tools; some require sensor or module replacement.
Stabilizer cylinder wear
Stabilizers see hard service every time the operator sets down. The 84259227 stabilizer cylinder seal kit is our #1 Super N seller, and the 84421606 complete stabilizer cylinder is the replacement when the original casting is past rebuild.
Swing tower pin and bushing wear
The swing tower takes the full load of every dig cycle. Multiple Super N bushings and pins move in volume — the 84326988, 84235607, 84246051, and 84249275 all see consistent monthly traffic. Symptoms of wear: boom slop, audible knock during swing reversals.
Dipper cylinder wear
The dipper cylinder is the highest-cycle hydraulic component on the backhoe. The 84259222 dipper cylinder seal kit is the verified Super N rebuild path. Replace seals at the first sign of weeping.
Bucket and quick coupler wear
The 84229979 mechanical quick coupler, 84223653 coupler pin, and 84170654 bucket link bushing are routine bucket-hardware wear items.
Loader tilt cylinder wear
The 91708357 loader bucket tilt cylinder is Super N-specific. Different part number than the 580N — confirm machine variant before ordering.
Cab air filtration
The AF55774 cab air filter covers 580N, 580SN, 590SN, and 580EV. Replace at major service intervals to keep the cab HVAC clean.
Filter kit for turbo Iveco engine
For Tier 4 Interim Super N machines (and 590 Super M Series II), the CS-590SM-II-FK filter kit is the verified maintenance set.

Request a PartWhere the 580 Super N sits in the Construction King family
The 580 Super N is the N-generation turbocharged Construction King small-frame backhoe loader and represents the current state of the Case backhoe platform. It sits alongside the naturally aspirated 580N. Above it sits the larger-frame 590 Super N (same engine family, larger chassis). Before it came the 580 Super M with the Case 445T/M family. The 580EV electric variant (2024+) shares the Super N chassis with a 71 kWh battery in place of the diesel engine. The Super N's emissions and after-treatment evolution — Tier 3 to Tier 4 Interim to Tier 4 Final — represents the most consequential running update in the Construction King's modern history.
