Fiat 640SH: 13.0 ml/rev, 160 bar, clockwise (CW). Flexible MOQ by model and order value; 1–2 pcs can be considered at a higher unit price.
The Fiat 640SH pump is recorded at 13 ml/rev with a 5/8-18 UNF feed and an M14×1.5 discharge connection. These mixed thread standards are a key ordering detail. It is clockwise, while the similarly sized 480SH version runs counterclockwise; never select by the 13 ml/rev figure alone.
Use FIAT as the initial parts-search term for Fiat 640SH. A cross-reference only narrows the candidate list; the sealing face, drive shaft and oil connections must agree with the machine being repaired.
No specific tractor serial ranges are established here for Fiat 640SH. Use the parts manual and existing hardware to complete the application check.

Rotation is specified as clockwise for Fiat 640SH. The sign of this dimension is decisive even when the housing and gear-drive arrangement appear nearly identical.
For hose matching, write down both port specifications: feed 5/8-18 UNF, discharge M14×1.5. Thread class and sealing face matter as much as nominal size.

Fiat 640SH carries a 13.0 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, Fiat 480SH lists 13.0 ml/rev and 160 bar. That is a useful limit check for the Fiat 640SH hydraulic request, not permission to alter the tractor’s original pump rating.
In addition to displacement, the table provides 6.0 L/min controlled flow. This is a separate selection datum and needs its own confirmation in the machine.
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.
Cleanliness is particularly important while servicing Fiat 640SH. Keep the hydraulic ports capped and check for swarf or grit in the suction line; contamination can damage a replacement before its first working cycle.
Make the clockwise/counterclockwise check explicit in the workshop instruction: Fiat 640SH is CW.
Consider Fiat Fiat 480SH only as a reference to compare: it is designated CCW and has 13.0 ml/rev. Fiat 640SH is designated CW, so any departure in direction or shaft style must be resolved.
When two options remain, request front and side views of the actual units rather than treating parts-list overlap as a full approval.
Quote the complete cross-reference FIAT and include the existing pump’s mounting view. If there is an unusual fitting, supply a close-up with a ruler or a thread gauge reading.
Let the quotation identify any uncertainties in compatibility before manufacturing begins.
No. Confirm the exact pump removed from the tractor, its drive-side rotation and its connection geometry.
Yes. It confirms how the existing pump is connected and whether a controlled-flow or tandem function needs separate attention.
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.
