Fiat 480BH Tractor Hydraulic Gear Pump Replacement

Working back from the old part

Use FIAT as the initial parts-search term for Fiat 480BH. A cross-reference only narrows the candidate list; the sealing face, drive shaft and oil connections must agree with the machine being repaired.

No specific tractor serial ranges are established here for Fiat 480BH. Use the parts manual and existing hardware to complete the application check.

Technical specifications

Shaft-end direction and port layout

Fiat 480BH is marked counterclockwise rotation. Identify the shaft end before interpreting the arrow and compare the actual pump drive direction with the equipment drawing.

For hose matching, write down both port specifications: feed M18×1.5, discharge M16×1.5. Thread class and sealing face matter as much as nominal size.

Before choosing the nearest-looking pump

The adjacent Fiat Fiat 640BH part has direction CW, while Fiat 480BH is CCW. Rotation is a hard constraint even if two supplier listings show comparable capacities.

A hydraulic pump replacement is only correct when dimensional and operational compatibility are both demonstrated.

What the rated values mean

Fiat 480BH carries a 11.0 ml/rev displacement entry. This is not a stand-alone guarantee of a required lift speed; the working rpm and load-dependent losses remain system-specific.

Within the comparison set, Fiat 640BH lists 11.0 ml/rev and 160 bar. That is a useful limit check for the Fiat 480BH hydraulic request, not permission to alter the tractor’s original pump rating.

A separate controlled-flow line gives 6.0 L/min. Keep that figure distinct from an estimated geometric delivery based on displacement.

The stated speed is 500–3000 rpm. Before commissioning, verify the engine accessory drive ratio and that normal operating conditions do not exceed this listing.

Preventing a repeat failure

Before removing Fiat 480BH, mark each hydraulic hose with its original position and note how the drive coupling engages. Then check the condition of the drive teeth, mounting gasket and fasteners on the old unit.

Make the clockwise/counterclockwise check explicit in the workshop instruction: Fiat 480BH is CCW.

Complete the pump identification

Send model Fiat 480BH, the quantity and one legible photo of the part mark. For interface review, add the drive-shaft profile, bolt spacing and a drawing of the port locations.

Let the quotation identify any uncertainties in compatibility before manufacturing begins.

Technical questions from buyers

Is the Fiat tractor name sufficient for ordering?

No. Confirm the exact pump removed from the tractor, its drive-side rotation and its connection geometry.

How does Fiat 480BH compare with Fiat Fiat 640BH?

The comparison shows 11.0 ml/rev for the other part and 11.0 ml/rev here; rotation and mechanical interfaces must also be checked.

Ordering, samples and shipping terms

Order quantities are set according to pump type and total order value. A small order of 1–2 pieces can be considered at a higher unit price; new customers may request 1–5 samples when the item is suitable. Mixed-model orders are available, normally with a combined order value of approximately USD 1,500.

Typical production schedules are 10–25 working days for standard items, 20–45 working days for customized components, and 45–120 working days for project equipment. Usual delivery terms are EXW, FOB, CIF and DAP. FCA, CFR, CPT, CIP and DDP can be discussed for specific shipments. Confirm the final schedule and terms with the quotation.
