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....
Ford 81836736: tractor hydraulic gear pump replacement reference
The 81836736 entry relates to numerous compact and utility Ford tractor references, including several 2810–5030 designations. The unusually broad application spread makes serial-range checking especially important. No numerical flow or pressure rating appears in this entry, so sizing must be confirmed from the original pump or machine manual.
Identification before quotation
The catalogue associates this assembly with 81836736. It is a sourcing reference rather than a controlled installation drawing, so no unlisted dimensions are presumed.
The listed tractor applications include 2810, 2910, 3230, 3400, 3420, 3430, 3610, 3900, 3910, 3930, 4100, 4110, 4130, 4600, 4610, 4630, 4830, 5030. Confirm the exact tractor build and its previously fitted pump, especially when several series names share one catalogue row.

Shaft-end direction and port layout
Rotation is specified as clockwise for 81836736. The sign of this dimension is decisive even when the housing and gear-drive arrangement appear nearly identical.
Installation hardware must suit the unlisted inlet on the supply side and the unlisted outlet on the discharge side. A port-size match alone does not prove the mount will align.

Selection checkpoints within the series
Ford 83928509 appears in the same broad product range. Compared with its unstated ml/rev displacement, the unlisted ml/rev for 81836736 is not enough to establish replacement suitability.
A hydraulic pump replacement is only correct when dimensional and operational compatibility are both demonstrated.

Correcting a size mismatch
A numeric specification sheet has not been established for 81836736. Obtain displacement and maximum permitted pressure from the actual component record before making a comparison.
Until the displaced volume for 81836736 is documented, a parts quotation should refer to the exact reference 81836736, 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.
Commissioning considerations
Cleanliness is particularly important while servicing 81836736. 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.
Circuit operating flow remains unquantified in this row, so a controlled functional check is needed once the pump is installed.
The dimensions needed to quote
Quote the complete cross-reference 81836736 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.
Ask for an outline drawing when a tight installation envelope leaves little room for adapters.
Two questions worth resolving
Which information distinguishes 81836736 from adjacent entries?
The OEM number, CW handedness and the listed feed/discharge values should be checked together with the flange.
Can the opposite clockwise pump be fitted?
No interchangeability is implied. The supplied listing is CW 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.
Third-party brand names and trademarks are used only for product identification and cross-reference. They remain the property of their respective owners; such references do not imply affiliation, sponsorship, authorization or endorsement.
