Fiat 480 Tractor Hydraulic Gear Pump Replacement – 5179722

GBC-5179722 — Fiat 480 Tractor Hydraulic Gear Pump Replacement – 5179722

The Fiat 480 is a compact row-crop tractor in the 45–50 hp range, making it one of the smaller models in the Fiat agricultural series. Its narrow track width and low ground clearance made it particularly suitable for work between grapevine rows, in olive groves, and in other close-planted orchard configurations where larger tractors cannot operate without causing crop damage. In Australia, small-frame Fiat tractors including the 480 are found on boutique wineries, small fruit orchards, and intensive market gardens — farms where hydraulic reliability is essential but the tractor fleet size does not justify a large parts inventory.

The {sku} is an aftermarket replacement hydraulic gear pump matched to OEM reference 5179722 for the Fiat 480 and closely related compact series models. It delivers correct hydraulic flow for the 3-point hitch, remote cylinder, and auxiliary implement circuits on these compact tractors.

OEM Reference and Compact Fiat Series Fitment

The 5179722 OEM reference identifies the specific hydraulic pump for the Fiat 480 compact series. The Fiat compact tractor range of this era used several different pump displacements matched to the output requirements of the specific model’s hydraulic circuit — confirm that 5179722 appears on your existing pump body before ordering.

Technical Specifications

Small Fiat Tractors in Orchard and Vineyard Work

Orchard and vineyard tractors like the Fiat 480 are specifically selected for their ability to operate in confined inter-row spaces without damaging root zones or canopies. The hydraulic system on these compact tractors must deliver reliable performance for side-mount mower positioning, spray boom height control, and 3-point hitch implement depth adjustment — all of which require precise, responsive hydraulic control. A worn gear pump on a vineyard tractor is not merely a maintenance issue; it directly affects the quality and precision of cultural operations during the growing season.

Compact Fiat tractors in vineyard and orchard service typically accumulate hours in a seasonal pattern — high utilisation during pruning, spraying, and harvest, lower use in off-season. This cyclical pattern can accelerate seal degradation on hydraulic pumps because the seals experience repeated heat-up and cool-down cycles during the high-utilisation season. Monitoring for early signs of pump seal failure — oil weeping around the shaft or pump body — allows planned replacement of the {sku} during the off-season rather than emergency replacement mid-harvest.

Installation and Compact Tractor Pump Care

On compact Fiat tractors like the 480, pump accessibility is generally good due to the compact layout of the transmission and hydraulic block. Take care when removing hydraulic hoses — residual fluid pressure may be retained in the circuit even after engine stop. Use a clean drain pan and cap all open connections immediately to prevent contamination of the small-capacity hydraulic sump.

After fitting the {sku}, pre-fill through the inlet port and start the engine at low idle. Cycle the 3-point hitch and any connected remote cylinder circuit to bleed air from the system. Check fluid level and top up as required. Visit our contact page for ordering or About Us for our sourcing credentials.
