Fiat 5129488 / 19 cc: tractor hydraulic gear pump replacement reference
Fiat reference 5129488 increases the listed displacement to 19 ml/rev at the 160 bar rating of the earlier 11 ml/rev models. Its 20 mm/15 mm port values also change. Assess circuit demand and input torque before replacing a smaller pump with this unit merely because its housing appears similar.
Identify the original unit
When an original unit has been changed before, the tractor badge can be misleading. Use the physical unit carrying 5129488 and its drive-end photograph as the starting point.
No specific tractor serial ranges are established here for 5129488 / 19 cc. Use the parts manual and existing hardware to complete the application check.

Reading the hydraulic specification
5129488 / 19 cc carries a 19.0 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, 11 cc clockwise lists 11.0 ml/rev and 160 bar. That is a useful limit check for the 5129488 / 19 cc 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.
What must mate to the original pump
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.
For hose matching, write down both port specifications: feed Ø20, discharge Ø15. Thread class and sealing face matter as much as nominal size.

Selection checkpoints within the series
A search may surface Fiat 11 cc clockwise alongside this reference. Check the pressure annotations (160 bar versus 160 bar), gear-end view and port layout before accepting the suggestion.
It is often worth checking the original pressure-line location before discussing any adapter or revised hose.
Hydraulic cleanliness and coupling fit
For a unit marked 5129488, 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.
Make the clockwise/counterclockwise check explicit in the workshop instruction: 5129488 / 19 cc is CW.
RFQ information that avoids rework
Please identify the tractor or engine installation for 5129488 / 19 cc, together with the serial number if available. A sketch showing the Ø20 and Ø15 connections will shorten the matching process.
Let the quotation identify any uncertainties in compatibility before manufacturing begins.
Frequently checked details
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 5129488 / 19 cc compare with Fiat 11 cc clockwise?
The comparison shows 11.0 ml/rev for the other part and 19.0 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.
