Fiat 5179722 / Fiat 480: tractor hydraulic gear pump replacement reference
For Fiat 480, the 5179722 listing is the clockwise partner to 5129478. Both are shown at 11 ml/rev, 160 bar, 500–3200 rpm and 20 mm/13.6 mm holes. That near-match makes a direction check essential; a common capacity figure must not decide a replacement by itself.
Working back from the old part
The most helpful evidence for identifying 5179722 / Fiat 480 is an original part mark and a clear shaft view. Port position and flange outline should be supplied at the same time.
No specific tractor serial ranges are established here for 5179722 / Fiat 480. Use the parts manual and existing hardware to complete the application check.

What the rated values mean
The 11.0 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, 5129478 / Fiat 640 lists 11.0 ml/rev and 160 bar. That is a useful limit check for the 5179722 / Fiat 480 hydraulic request, not permission to alter the tractor’s original pump rating.
A separate controlled-flow line gives 16.0 L/min. Keep that figure distinct from an estimated geometric delivery based on displacement.
The stated speed is 500–3200 rpm. Before commissioning, verify the engine accessory drive ratio and that normal operating conditions do not exceed this listing.
Selection checkpoints within the series
The part Fiat 5129478 / Fiat 640 is similar enough to deserve a check, not similar enough to presume interchangeability. Differences in CCW/CW handedness or 11.0/11.0 displacement can affect both installation and operation.
When two options remain, request front and side views of the actual units rather than treating parts-list overlap as a full approval.
Hose connection checks
Even a correct cross-reference can fail if the drive turns the wrong way. The 5179722 / Fiat 480 listing indicates clockwise, so trace the machine’s drive direction before use.
The feed port is shown as Ø20; the discharge port as Ø13.6. Confirm the fitting seat and whether the opening is measured as a bore or a thread.

Hydraulic cleanliness and coupling fit
Inspect the hydraulic reservoir and filter when changing to 5179722 / Fiat 480. Recording the original failure symptoms and checking a blocked feed line may prevent an immediate second failure.
Correct relief protection and uncontaminated oil matter more than the appearance of the replacement housing.
The dimensions needed to quote
For 5179722 / Fiat 480, the most useful RFQ attachments are a shaft-end image, a drawing of the fastening pattern and the existing hose connector specification.
Please highlight any change from the original connection standard to avoid quotation assumptions.
Two questions worth resolving
Can I order 5179722 / Fiat 480 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.
How does 5179722 / Fiat 480 compare with Fiat 5129478 / Fiat 640?
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.
