If you've ever tried to order parts for a Case 580 and thought, "It's a 580 — that's all I know" — you're not alone. And if you've ever ordered the wrong part because of it, you're really not alone.

Here's the issue: "580" is the family name, not the full identity. Case built this machine in a long, continuous line from 1966 all the way through the 2000s, and they changed a lot from one series to the next — and sometimes within the same series. Transmissions, hydraulic cylinder designs, steering components, axle configurations, pins, bushings, electrical setups — none of it is universal across the family.

The fastest way to stop guessing is to use your machine's serial number. This guide walks you through matching that number to the year of manufacture, so you can confirm part compatibility before you order — and avoid the frustration of a return.

One Important Thing Before You Start

Serial Numbers (S/N) refer to the tractor (machine frame) only.

The loader, backhoe, engine, ROPS, and attachments each carry their own separate serial numbers. If your machine has had a loader or backhoe assembly swapped over the years — which is common on older equipment — those tags will identify the attachment, not the tractor. When you're ordering hydraulic seal kits, pins and bushings, or any tractor-specific component, the tractor serial number is your source of truth.

Don't confuse the ROPS plate inside the cab for the tractor serial number plate. They're different plates and the ROPS number won't help you identify the machine.

Where to Find Your Case 580 Serial Number

The plate location shifted over the decades, so here's where to look by era:

Older models (580B, 580C, 580D): Left side of the dash, just inside the left cab door — or under the left door on the side of the frame rail.

Later models (580E through 580M): Left side of the dashboard inside the cab, or the left cab door frame area. On some machines the plate may also appear near the left lift arm base.

How Serial Number Formats Changed Over Time

Case's numbering system evolved significantly across the production run:

• Up through the E series — 7 or 8 digits starting with 8 or 9 (example: 9879000)
• E series through early K — 8 digits often starting with 17 (example: 17044575)
• Late 1980s K series onward — 10-digit numbers with a JJG prefix (example: JJG0213787)
• 2004 and later — 9-digit numbers with an N5C prefix, where the second digit encodes the year of manufacture (example: N5C415308 = 2004)
• 2014 and later — 17-digit VIN-style numbers (example: JJGN580NCDC581129)

Serial Number Ranges by Series and Year

580CK — "Construction King" (1966–1971)

The original. Open operator station, no cab. This machine established the 580 nameplate. Parts availability is limited but some components still carry over.

Year	Beginning S/N	Ending S/N
1966	8279001	8307000
1967	8307001	8332500
1968	8332501	8356500
1969	8356507	8650000
1970	8650001	8674000
1971	8674001	8697900

All 580-series machines through this era carry "CK" in the model name, standing for Construction King. For example, a 580C CK = Model 580, Series C, Construction King.

580B — Series B (1971–1976)

The 580B introduced more refinement and is still widely used today. You may see a serial number overlap with the CK in 1971 depending on transition timing at the factory. Browse 580B parts and specs →

Year	Beginning S/N	Ending S/N
1971	8674001	8691900
1972	8691901	8712000
1973	8712001	8736600
1974	8736601	8770000
1975	8770001	8797500
1976	8797501	8809950

Common service areas on the 580B: brake failure is a known weak point; hydraulic leaks around cylinders are frequent. Use split-piston style seal kits for this era — the piston design is different from later machines, and ordering the wrong kit is a very common mistake.

580C — Series C (1975–1980)

Note that the 580C overlaps with the end of 580B production — Case ran both simultaneously for a period. The C introduced a more refined hydraulic system and remains a popular machine with solid parts availability. Browse 580C parts and specs →

Year	Beginning S/N	Ending S/N
1975	8950001	8950151
1976	8950152	8957500
1977	8957501	8969419
1978	8969420	8980715
1979	8980716	9002749
1980	9002750	9011940

Important for 580C hydraulics: The C was produced with both split (two-piece) pistons and one-piece pistons late in production. Check the gland face — a number stamped there starting with G1 indicates a one-piece piston. No G1 stamp = split-piston style. Use 580C/D/E seal kits for this machine.

580D & 580 Super D (1980–1983)

The D series brought updated powerplant options and improved loader geometry. The Super D added turbocharged power. Full serial number guide for CK through D →

Year	Beginning S/N	Ending S/N
1980	9050041	9051569

1982	9062065	9081280
1983	9081281	9863699

580E & 580 Super E (1983–1987)

The E series marked a significant evolution — new cab design, updated hydraulics, and the introduction of the extendahoe option on Super E models. Serial numbers in this range shift from the 9-prefix style to the 17-prefix format.

Model Year	Beginning S/N	Ending S/N
1983	9705919	9868199
1984	9868100	17025399

The 580E and Super E share hydraulic cylinder seal kits with the 580C and 580D. Shop 580C/D/E/Super E seal kits →

Why Case skipped F, G, and H: The 580F was built in France, the 580G in France, and the 580H in Brazil — international market machines. The next domestic model became the 580K.

580K (1986–1991)

A major update to the platform. The K introduced the JJG serial number prefix partway through production, which can cause confusion — some early K machines still carry 17-prefix numbers.

Year	Beginning S/N	Ending S/N
1986	17417801	17417849
1987	17417850	JJG0006900

1990	JJG0022285	JJG0030517
1991+	JJG0030518+	—

Phase III note: 580K machines built from serial number JJG0020000 onward are considered Phase III. This matters for transmission and axle parts — Phase I and Phase III use different components in some cases.

580 Super K (1991–1994)

The Super K replaced the standard K and ran through 1994. It's a popular machine for small contractors — durable, straightforward to service, and parts are still widely available.

Year	Approximate S/N Range
1992	Up to JJG0164348
1993	JJG0164349 – JJG0171539
1994+	JJG0177307 and beyond

580L (1995–1999)

The L series brought a more modern cab and updated hydraulics. It was produced in two series — Series I and Series II — which used different components in certain areas. Knowing which series you have matters when ordering hydraulic seal kits.

Year	Beginning S/N	Ending S/N
1995	JJG0218894	JJG0221531

580 Super L / 580SL (1995–1998)

The Super L ran alongside the standard 580L and offered a higher-horsepower engine and additional capacity. It transitioned to the Super L Series II in 1998.

580M & 580 Super M (2001–2006+)

The M series came in three sub-series, each with different engine configurations:

• Series I — Cummins 4B and 4BT engines
• Series II — Iveco engines
• Series III — Iveco engines (continued)

This distinction matters for engine-related parts, filters, and injection system components.

580M Series I (2001–2003)

Year	Beginning S/N	Ending S/N
2001	JJG021318	JJG026127
2002	JJG026128	JJG041827
2003+	JJG041828+	—

580M Series II (2003–2006+)

Serial numbers shift to the N5C prefix format with the Series II.

Year	Beginning S/N	Ending S/N
2003	N5C411001	N5C415307
2004	N5C415308	N5C420059
2005	N5C420060	N5C425035
2006+	N5C425036+	—

Decoding N5C numbers: On 2004-and-later machines, the second digit of the serial number encodes the year of manufacture. N5C415308 — the "4" = 2004. Faster than digging through a chart.

Why This Matters When Ordering Parts

Two machines can both be called "Case 580" and still require completely different parts. Serial number breaks affect:

• Transmission and clutch setups
• Hydraulic cylinder piston style (split vs. one-piece)
• Steering components
• Axle and driveline parts
• Pins and bushings
• Electrical system variants
• Engine and fuel system components

Your serial number is the one thing that cuts through all of that. Have it ready when you call or order — it's what our team uses to confirm fitment and make sure what ships to you actually fits.
