Ford 83957379 Tractor Hydraulic Gear Pump Replacement

Model identity and its limits

The main identification for this entry is 83957379. The accompanying reference list is 83957379; D8NN600AC; E0NN600AB; E0NN600AC; compare the reference stamped on the removed body rather than relying on a generic seller photo.

The listed tractor applications include 5110, 5610, 6410, 6610, 6710, 6810, 7010, 7410, 7610, 7710, 7810, 7910, 8010, 8210. Confirm the exact tractor build and its previously fitted pump, especially when several series names share one catalogue row.

Technical specifications

Correcting a size mismatch

There is no published nominal displacement, pressure ceiling or shaft-speed range against 83957379. Quoting a number from a neighboring Ford pump would create a false specification; send the unit’s stamp or ask for a dimensional drawing first.

Until the displaced volume for 83957379 is documented, a parts quotation should refer to the exact reference 83957379, the pump drive and the application. A neighboring catalogue row cannot fill the missing capacity or pressure fields.

Flow-control behavior is not defined by this parts entry. Confirm the tractor valve and circuit characteristics independently.

There is no published shaft-speed band; do not assign a maximum rpm without an original specification.

Same family, different pump

The adjacent Ford 81871528 part has direction CW, while 83957379 is CW. Rotation is a hard constraint even if two supplier listings show comparable capacities.

The complete assembly should be assessed, including drive-end engagement and the supply port.

Shaft-end direction and port layout

For this part, the drive runs clockwise. Obtain an end-on shaft photo so the assembly orientation can be checked unambiguously.

The feed and discharge entries are not listed and not listed. Establish whether each is a plain port, a thread or a connection requiring a separate sealing element.

Hydraulic cleanliness and coupling fit

Confirm the tractor pump bracket is rigid and the shaft sits without axial force when 83957379 is installed. The original line arrangement should not load the aluminium body through unsupported fittings.

A repair should be assessed against the unknown pressure entry and the unlisted operating-speed specification, not simply whether the pump produces movement.

RFQ information that avoids rework

The enquiry for 83957379 should state expected order volume, required shipment term and any drawing that controls shaft projection. Mention whether this is a first sample or a repeat order.

If different pump types are required in one shipment, show quantities separately so the mixed-order arrangement can be priced correctly.

Two questions worth resolving

Does reference 83957379 guarantee that 83957379 fits?

No; the part number helps with identification, but the shaft, sealing face, ports and CW rotation need checking.

What does unlisted ml/rev mean for flow?

The nominal displacement is missing here and must be obtained before estimating output.

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.
