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....
UTB PRD 54 T-00 / UTB 650: tractor hydraulic gear pump replacement reference
UTB PRD 54 T-00 is associated with the UTB 650 manufacturer reference. Its 11 ml/rev capacity, 160 bar rating and 12.0 L/min controlled-flow entry should be considered together with anticlockwise rotation. Matching the 20 mm inlet-side hole and 13.6 mm discharge-side hole is the first step, followed by checking the flange drive interface.
Working back from the old part
When an original unit has been changed before, the tractor badge can be misleading. Use the physical unit carrying PRD 54 T-00 and its drive-end photograph as the starting point.
No specific tractor serial ranges are established here for PRD 54 T-00 / UTB 650. Use the parts manual and existing hardware to complete the application check.

Preventing a repeat failure
For a unit marked PRD 54 T-00, 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.
Correct relief protection and uncontaminated oil matter more than the appearance of the replacement housing.
How to compare pump sizes
The 11.0 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, 5129478 / Fiat 640 lists 11.0 ml/rev and 160 bar. That is a useful limit check for the PRD 54 T-00 / UTB 650 hydraulic request, not permission to alter the tractor’s original pump rating.
A separate controlled-flow line gives 12.0 L/min. Keep that figure distinct from an estimated geometric delivery based on displacement.
The stated speed is 500–3200 rpm. Before commissioning, verify the engine accessory drive ratio and that normal operating conditions do not exceed this listing.

Ports and drive-side orientation
The directional entry is CCW, viewed using the catalogue’s shaft orientation. A correct replacement should use the same viewing convention rather than assuming clockwise from the engine side.
The feed port is shown as Ø20; the discharge port as Ø13.6. Confirm the fitting seat and whether the opening is measured as a bore or a thread.

Close relatives are not identical
A search may surface Fiat 5129478 / Fiat 640 alongside this reference. Check the pressure annotations (160 bar versus 160 bar), gear-end view and port layout before accepting the suggestion.
A hydraulic pump replacement is only correct when dimensional and operational compatibility are both demonstrated.
How to specify this replacement
Please identify the tractor or engine installation for PRD 54 T-00 / UTB 650, together with the serial number if available. A sketch showing the Ø20 and Ø13.6 connections will shorten the matching process.
Please highlight any change from the original connection standard to avoid quotation assumptions.
Two questions worth resolving
Can I order PRD 54 T-00 / UTB 650 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.
