Fiat 480SH Tractor Hydraulic Gear Pump Replacement

Matching the machine history

If the existing machine’s service documentation lists Fiat 480SH, check the full cross-reference FIAT. The serial range and original pump details still determine the final match.

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

Technical specifications

How to compare pump sizes

The 13.0 ml/rev figure represents swept volume, not a constant litres-per-minute delivery. For a correct substitute, ask whether the hydraulic equipment was designed around the same shaft-speed band.

Within the comparison set, Fiat 640SH lists 13.0 ml/rev and 160 bar. That is a useful limit check for the Fiat 480SH hydraulic request, not permission to alter the tractor’s original pump rating.

The flow-control annotation reads 6.0 L/min. Keep it with the original pump record rather than treating it as a measured output at 500–3000 rpm.

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.

Cross-reference comparison

Fiat Fiat 640SH appears in the same broad product range. Compared with its 13.0 ml/rev displacement, the 13.0 ml/rev for Fiat 480SH is not enough to establish replacement suitability.

A supplier can review alternatives after the damaged part is identified by its original drawing or measurements.

Hydraulic plumbing and rotation

Checking rotation for Fiat 480SH requires a known viewpoint. Record whether the shaft was observed from the coupling face, as the listing gives counterclockwise.

The feed port is shown as 5/8-18 UNF; the discharge port as M14×1.5. Confirm the fitting seat and whether the opening is measured as a bore or a thread.

Hydraulic cleanliness and coupling fit

Before the first start, rotate the drive in the correct direction by the approved maintenance procedure and verify Fiat 480SH receives oil. Run unloaded initially and monitor for abnormal sound or leakage.

Correct relief protection and uncontaminated oil matter more than the appearance of the replacement housing.

Information to put on the purchase enquiry

If replacing a failed Fiat unit, share its stamped identifier, gearbox or engine-side drive photo and port measurements. The listed 160 bar pressure is not a substitute for the machine’s actual relief setting.

Please highlight any change from the original connection standard to avoid quotation assumptions.

Frequently checked details

Can I order Fiat 480SH using just an equipment model number?

It is better to provide the original pump marking and photos, especially when a tractor has had earlier repairs or modifications.

What does 13.0 ml/rev mean for flow?

It describes displacement per revolution, not a guaranteed service flow; compare actual shaft rpm and pump efficiency.

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.
