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 81863197 / 16 cc: tractor hydraulic gear pump replacement reference
The 16 ml/rev Ford pump is listed at 160 bar and 2000 rpm with an anticlockwise drive. Its 20 mm feed hole and 13.5 mm discharge hole distinguish it from nearby Ford entries that carry no performance table. The rotation note is as important as the displacement when looking for a drop-in replacement.
What the part number resolves
The catalogue associates this assembly with 81863197. It is a sourcing reference rather than a controlled installation drawing, so no unlisted dimensions are presumed.
No specific tractor serial ranges are established here for 81863197 / 16 cc. Use the parts manual and existing hardware to complete the application check.

What the rated values mean
The 16.0 ml/rev figure represents swept volume, not a constant litres-per-minute delivery. For a correct substitute, ask whether the hydraulic equipment was designed around the same shaft-speed band.
Within the comparison set, 83913537 / 33 cc lists 33.0 ml/rev and 200 bar. That is a useful limit check for the 81863197 / 16 cc hydraulic request, not permission to alter the tractor’s original pump rating.
No controlled-flow rate is specified for this item; please include duty conditions if that value is required in the RFQ.
The stated speed is 2000 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
One of the first installation checks is direction: this reference is CCW. Also check that the pump body can be seated without stressing the hoses.
The feed port is shown as Ø20; the discharge port as Ø13.5. Confirm the fitting seat and whether the opening is measured as a bore or a thread.

Close relatives are not identical
As a sanity check, compare this entry with Ford 83913537 / 33 cc. A near-identical picture is weaker evidence than distinct OEM numbers, connection shapes and the stated CCW rotation.
A hydraulic pump replacement is only correct when dimensional and operational compatibility are both demonstrated.
Preventing a repeat failure
Use the dismantling photographs to place 81863197 / 16 cc at the same mounting angle as the original. Verify that hoses reach naturally and that no connection has been cross-threaded or over-tightened.
Correct relief protection and uncontaminated oil matter more than the appearance of the replacement housing.
Complete the pump identification
Include the part 81863197, the delivery destination and any customization needs. Attach the removed pump’s outline dimensions rather than depending on an estimated scale from the catalogue image.
Please highlight any change from the original connection standard to avoid quotation assumptions.
Before you approve a replacement
Can I order 81863197 / 16 cc using just an equipment model number?
It is better to provide the original pump marking and photos, especially when a tractor has had earlier repairs or modifications.
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.
