Case 480F Construction King: Specs, Parts & Common Issues

Produced 1992 through 1995 — the final model in the Case 480 Construction King series. Same Cummins 4-390 (4B 3.9L) engine as the 480E, mechanical and power shuttle drivetrains, 2WD and Carraro 4WD configurations, and a 480F LL Landscape Loader variant offered alongside.

The Case 480F is the last model in the Case 480 Construction King series. Produced from 1992 through 1995, the 480F carried the Cummins 4-390 engine forward from the 480E and was effectively the same machine with refined hydraulics and cosmetics. When 480F production ended, Case did not replace it directly — the small-frame Construction King role was absorbed by the 580K and 580 Super L families on the larger platform.

This guide covers the verified specifications, the engine and drivetrain options, the 2WD and 4WD front axle configurations, the 480F LL Landscape Loader variant, the failure modes 480F owners report most often, and the parts we stock with confirmed 480F fitment.

At-a-glance specifications

Where to find the serial number plate

The 480F carries its tractor serial on a stamped data plate riveted to the left side of the tractor frame rail, near the clutch housing under the left loader tower. By the 480F era, all serials carry the JJG prefix (Burlington, Iowa plant code). The Cummins 4-390 engine has its own block-stamped serial below the cylinder head.

Production years

The Case 480F was built from 1992 through 1995 — the 480F LL Landscape Loader variant continued slightly later, with some sources extending its production through 1997 or 1999 for tail-end deliveries. When the 480F line ended, Case did not introduce a 480G or other direct successor; the small-frame Construction King role was rolled into the 580K and later 580 Super L families.

A single, publicly authoritative Case-published year-by-serial table for the 480F is not in the open record. Read the serial off the frame plate and verify through a Case dealer database before ordering anything tied to engine, drivetrain, or front-axle internals.

Engine and powertrain

The 480F is powered by the Case 4-390 — Case's catalog name for the Cummins 4B 3.9L four-cylinder naturally aspirated diesel. 239 cubic inches, 69 HP gross at 2,200 rpm, 186 lb-ft of torque at 1,200 rpm. This is the same engine carried over from the 480E and used across the late Case 580 Super E, 580K, and several dozer and skid steer models from the same era. Parts availability is excellent — Cummins 4B consumables are everywhere.

Fuel system varies across the production run. Early 480Fs typically use a Roosa Master / Stanadyne rotary injection pump; later builds switched to a Lucas / CAV rotary pump. The injector lines differ between the two — verify your IP type before ordering injector lines or pump seal kits.

Two transmission options were offered factory:

• 4-speed mechanical shuttle — single dry clutch, four gears forward and reverse, manual shuttle lever.
• 4-speed power shuttle — torque converter coupled, hydraulically actuated forward/reverse clutch pack. This is the popular factory configuration and the source of most documented drivetrain failures.

Loader and backhoe capacities

4WD front axle and the 480F LL variant

The 480F was offered with an optional Carraro 4WD front axle using planetary hub reduction — same architecture as the 480E, with king pin assemblies on each spindle and stud-mounted hubs that share parts with the 580K, 590 Super L, and other Carraro-equipped Case backhoes of the era. 2WD remained the base configuration. The 4WD upgrade is the source of several documented high-hour wear items (planetary gears, king pins, hub bearings) listed in the parts table.

Case 480F LL (Landscape Loader)

Case also offered the 480F LL as a loader-only Landscape Loader configuration — same powertrain and front axle options as the standard 480F, but no backhoe attachment and a different rear frame. Used in landscape, light utility, and skip-loader applications. Production of the 480F LL extended slightly beyond the standard 480F. The 480F LL has its own filter service kit and decal set in our catalog.

Common problems documented by owners

The following failure modes reflect what 480F owners report most often. Diagnose in order before replacing major components.

Power shuttle forward clutch burn-up

The most-reported 480F drivetrain failure. Symptoms include the machine driving in reverse but slipping or dropping out in forward, with metal and clutch material in the shuttle pan strainer. Root cause is usually upstream — low Hytran fluid, wrong fluid in the shuttle, or a plugged oil-cooler line starving the clutches of cooling. Inspect the oil cooler line and pan strainer before condemning the clutch pack.

Power shuttle "kick-out" solenoid

Documented intermittent failure of the 2-wire kick-out solenoid on the left side of the shuttle housing. Symptom: the machine drops out of gear under load or won't engage from neutral consistently. Replacement solenoid is a straightforward service item.

Brake master cylinder failure (dual under-dash masters)

The 480F uses two separate master cylinders under the dash, one per side, feeding hydraulically actuated bonded discs in drum-style housings. Spongy pedal, one-side-only operation, and pedals that won't hold are usually internal seal failure in one or both master cylinders. The bleed sequence is sensitive — work the side that's farther from the cab fluid reservoir first.

Cummins 4-390 head gasket weep

Common at high hours, especially on machines that have run overheated or with over-advanced injection timing. Symptom: coolant in the oil or external seepage at the deck, typically between cylinders 3 and 4. Replace with a Cummins 4B head gasket set and re-torque to spec.

Cummins 4-390 injection pump fade

Hard hot starts, weak power, and stalling under load on high-hour units trace to the rotary injection pump. Lucas / CAV and Roosa Master / Stanadyne builds have different rebuild paths — confirm pump type before ordering parts.

4WD Carraro axle wear

On 4WD-equipped 480Fs, the Carraro planetary hubs, king pins, planetary gear pins, and tie rod ends are documented high-hour wear items. Common symptom: clunking from the front end during turns, eventually progressing to leaking grease at the planetary hub.

Pin and bushing wear

Same as the rest of the 480 family — wallowed-out lift cylinder rod-end pins, loader tower pivot pins, backhoe boom-to-dipper pin, bucket-link bushings, and swing tower pins. Hardened replacement pins and bushings, plus full bucket-link assemblies that fit the 480D/E/F generation, are in stock.

Frequently asked questions

What years was the Case 480F made?

1992 through 1995. The 480F LL Landscape Loader variant continued slightly longer, with some references extending production through 1997.

What engine is in a Case 480F?

The Case 4-390 — Case's name for the Cummins 4B 3.9L four-cylinder naturally aspirated diesel. 239 cubic inches, 69 HP gross at 2,200 rpm, 186 lb-ft torque at 1,200 rpm. The same engine as the 480E.

Does the 480F have a power shuttle?

Both options were offered factory. Synchronized mechanical shuttle (4F/4R with dry clutch) and power shuttle (hydraulic clutch pack with torque converter) were both standard configurations. Power shuttle is the more common factory choice and the source of most documented drivetrain failures.

Does the 480F have 4WD?

4WD with a Carraro planetary front axle was offered as a factory option. Confirm 2WD vs. 4WD before ordering any front-end parts.

Does the 480F have wet-disc brakes?

No. The 480F uses hydraulically actuated bonded discs inside drum housings, with two separate master cylinders under the dash. Same architecture as the 480E and 480D. True wet-disc multi-plate brakes appeared on the 580 Super L generation but were never used on the 480-series.

What is the 480F LL?

The 480F LL (Landscape Loader) is the loader-only configuration without a backhoe — same engine and drivetrain as the standard 480F, used in landscape, skip-loader, and light-utility applications.

Was there a Case 480G?

No. The 480F is the last model in the Case 480 series. After 1995, Case did not produce a 480-series successor; the small-frame Construction King role was rolled into the 580K and 580 Super L families.
