Fiat 480 Tractor Hydraulic Gear Pump Replacement – 480BH

GBC-FIAT-480BH — Fiat 480 Tractor Hydraulic Gear Pump Replacement – 480BH

The Fiat 480 BH-series hydraulic pump is the left-hand (anti-clockwise) rotation variant with 11.0 ml/r displacement and M18×1.5 / M16×1.5 metric port threads. It is the counterpart to the Fiat 640BH, fitted to the smaller 480 frame. Like all external gear pumps on aged equipment, it is subject to wear that manifests as reduced hydraulic flow, noisy operation, and eventual loss of system pressure. When these symptoms appear, a direct-replacement pump is the most reliable and cost-effective repair.

The GBC-FIAT-480BH replaces the original Fiat 480 BH-series pump with a precision-manufactured aftermarket unit. Specification: 11.0 ml/r, 160 bar, anti-clockwise (left-hand) shaft rotation, M18×1.5 feed port, M16×1.5 discharge port. No machining, port adapters, or hose modifications are required for installation. For the complete GBC range, visit the GBC homepage.

MOQ: flexible. Minimum order value USD 1,500; mixed orders and trial quantities welcome.

OEM Reference Numbers and Fitment

The 480BH is the left-hand rotation, M18/M16-ported pump. Before ordering, verify: (1) shaft rotates anti-clockwise when viewed from the drive end; (2) feed port is M18×1.5 (not 5/8-18 UNF — that is the 480SH); (3) displacement is approximately 11 ml/r. If all three match, GBC-FIAT-480BH is the correct replacement. Contact us for any fitment queries.

Technical Specifications

Identifying the Correct Fiat 480 Pump Variant

The Fiat 480 was produced with at least two hydraulic pump configurations — the SH-series (13 ml/r, UNF feed port) and the BH-series (11 ml/r, M18 feed port). These are not interchangeable. The BH-series left-hand variant covered here (GBC-FIAT-480BH) differs from the right-hand 640BH in rotation direction only — the body, ports, and displacement are identical. Confirm rotation before ordering.

If your workshop handles multiple Fiat models, keeping a cross-reference of pump variants against machine serial numbers will streamline future ordering. Our sales team can assist with building that cross-reference — contact us with your fleet list.

Quality and Supply Chain

GBC tractor hydraulic gear pumps are manufactured to tight dimensional tolerances with hardened steel gears, close-tolerance housings, and quality shaft seals. Each pump is dimensionally inspected before dispatch. We supply directly to importers, agricultural parts dealers, and hydraulic workshops.

Commissioning After Pump Replacement

After fitting the GBC-FIAT-480BH, always perform a proper commissioning procedure: fill the pump housing with clean hydraulic oil via the inlet port before initial start; run at low engine idle (1,000 rpm) for the first five minutes; cycle the three-point linkage slowly and check for smooth, responsive operation; inspect all connections for leaks; and change the hydraulic filter after the first ten hours of operation to remove any residual installation debris.

Following these steps protects the new pump and gives it the best chance of a full service life. Contact us if you have any questions.
