Fiat 5180271 / 14 cc Tractor Hydraulic Gear Pump Replacement

Identification before quotation

The main identification for this entry is 5180271 / 14 cc. The accompanying reference list is 5180271; 5135887; 5167392; 5180275; compare the reference stamped on the removed body rather than relying on a generic seller photo.

No specific tractor serial ranges are established here for 5180271 / 14 cc. Use the parts manual and existing hardware to complete the application check.

Technical specifications

Hydraulic plumbing and rotation

Checking rotation for 5180271 / 14 cc requires a known viewpoint. Record whether the shaft was observed from the coupling face, as the listing gives counterclockwise.

Installation hardware must suit Ø20 on the supply side and M18×1.5 on the discharge side. A port-size match alone does not prove the mount will align.

Compared with a neighboring listing

As a sanity check, compare this entry with Fiat 5131170 / 14 cc. A near-identical picture is weaker evidence than distinct OEM numbers, connection shapes and the stated CCW rotation.

Only the relevant tractor variant and mounting geometry can settle a close call between two replacement choices.

Correcting a size mismatch

The nominal size of 5180271 / 14 cc is 14 ml/rev. The user should confirm both required pressure and expected duty cycle; a part that spins and bolts on can still perform poorly if incorrectly sized.

Within the comparison set, 5131170 / 14 cc lists 14 ml/rev and 200 bar. That is a useful limit check for the 5180271 / 14 cc hydraulic request, not permission to alter the tractor’s original pump rating.

Controlled flow is shown as 18 L/min for this listing. Its circuit function should be reviewed before specifying a valve or control setting.

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.

Workshop checks before installation

Before the first start, rotate the drive in the correct direction by the approved maintenance procedure and verify 5180271 / 14 cc receives oil. Run unloaded initially and monitor for abnormal sound or leakage.

If the application uses the printed 18 L/min controlled-flow value, check the existing priority/control valve setting as a separate step.

What the sales engineer should receive

If replacing a failed Fiat unit, share its stamped identifier, gearbox or engine-side drive photo and port measurements. The listed 200 bar pressure is not a substitute for the machine’s actual relief setting.

Ask for an outline drawing when a tight installation envelope leaves little room for adapters.

What buyers ask about this model

Which information distinguishes 5180271 / 14 cc from adjacent entries?

The OEM number, CCW handedness and the listed feed/discharge values should be checked together with the flange.

Can the opposite counterclockwise pump be fitted?

No interchangeability is implied. The supplied listing is CCW and the shaft-end reference direction must be confirmed.

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.
