Stainless steel gearboxes are widely used in industrial transmission fields due to their high strength and corrosion resistance. However, in actual use, stainless steel gearboxes may still malfunction due to improper design, installation, lubrication or maintenance....
Fiat 5131170 / 14 cc: tractor hydraulic gear pump replacement reference
Fiat 5131170 is the clockwise 14 ml/rev member of the 200 bar group. Its listed controlled-flow figure is 18 L/min, with a 20 mm feed hole and M18×1.5 discharge. The 5180271 part is close in capacity and ports yet opposite in rotation, making the full part reference essential.
Distinguishing a service variant
The most helpful evidence for identifying 5131170 / 14 cc 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 5131170 / 14 cc. Use the parts manual and existing hardware to complete the application check.

Same family, different pump
One comparison point is Fiat 5180271 / 14 cc, where the record shows 14 ml/rev and 200 bar. The present 5131170 / 14 cc specification (14 ml/rev, 200 bar) should be kept separate.
If the machine has been modified, the fitted pump is more useful evidence than a legacy tractor model number.
Displacement and duty considerations
The catalogue prints 14 ml/rev for this pump. When replacing it, avoid enlarging displacement on appearance alone: the input drive and relief protection were chosen around the original hydraulic demand.
Within the comparison set, 5180271 / 14 cc lists 14 ml/rev and 200 bar. That is a useful limit check for the 5131170 / 14 cc hydraulic request, not permission to alter the tractor’s original pump rating.
The flow-control annotation reads 18 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.

Commissioning considerations
For a unit marked 5131170, compare the housing register and drive stub before connecting pressure lines. A distorted mounting face or damaged coupling should be corrected rather than forcing the new pump into place.
Document any adaptor or hose changes so future replacements are not ordered against outdated dimensions.
Shaft-end direction and port layout
The directional entry is CW, viewed using the catalogue’s shaft orientation. A correct replacement should use the same viewing convention rather than assuming clockwise from the engine side.
Do not machine pipework from the illustration. The two connection callouts are feed Ø20 and discharge M18×1.5; check the physical unit first.

RFQ information that avoids rework
Please identify the tractor or engine installation for 5131170 / 14 cc, together with the serial number if available. A sketch showing the Ø20 and M18×1.5 connections will shorten the matching process.
For serial-sensitive machines, an equipment parts-list extract is especially helpful.
Common selection questions
What matters beyond the 5131170 / 14 cc cross-reference?
Look for a matching shaft profile, mounting flange and pressure-side connection; a parts number alone cannot settle every revision.
Is the 18 L/min controlled-flow value the total pump flow?
Not necessarily; controlled-flow information is separate from geometric displacement and actual delivery.
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.
