Why the Same Base Number Ships Across Multiple Engine Variants

Water Pump 4131A062 for Perkins 1104D-44T fitment & cross reference requires serial-level verification because the Perkins 1104 family spans more than a dozen sub-models with physical differences behind the same casting number.

The 1104A-44, 1104A-44T, 1104C-44T, 1104C-E44T, 1104C-E44TA, 1104D-44T, and 1104D-44TA all share the 4131A062 base identifier in most aftermarket catalogues. But inlet port position, gasket surface profile, and impeller configuration differ across these sub-models. Copy-pasted cross-reference tables between sellers mean errors travel fast — and a single wrong variant keeps the machine on the hardstand.

When a worn nameplate leaves only the machine model as a starting point — say a Massey Ferguson 593 or a Landini Trekker 85F — identification by physical inspection of the old pump becomes the only safe path. Port angle, shaft length, and flange hole spacing need measuring before committing to a replacement order.

Engine Serial Matching Across the Perkins 1104 and A4-Series Family

The Water Pump 4131A062 covers engines from the older A4.236 and A4.248 through the 1000.4WT, 1000.3WTI, 2160, and 2200 families, right up to the modern 1104D-44TA. Each transition point between sub-generations introduced machining changes to the cylinder block water jacket opening. Our technical team verifies your specific engine serial against documented variant changes so the pump you receive matches the block you have — not just the base number on a lookup table.

Port Position, Flange Pattern, and Shaft Interface Verification

Installation fitment depends on three physical interfaces: the inlet and outlet port orientation relative to the block, the gasket mating surface flatness, and the shaft seal engagement depth. The machined surface on this pump is finished to Ra 0.8 μm, which aligns with OEM service manual tolerances for the Perkins A4-series cylinder block face. Shaft runout is held to ≤0.03 mm under ISO 1940-1 G6.3 balance standards. Before you order, compare your old pump's port clocking position and flange bolt hole spacing against the incoming unit — even a few degrees of rotation difference can prevent hose routing in tight engine bays like the McCormick F75 or Landini Rex 75F.

Flow and Seal Specifications That Matter at Operating Temperature

The high-silicon aluminum alloy impeller (A-Si12Cu1Mg) resists cavitation erosion better than standard cast aluminum under sustained high-rpm operation typical in agricultural harvesting and quarry loading. Flow rate is rated at ≥28 L/min at 2,200 rpm, sufficient for the thermal load of turbocharged 1104 variants running under continuous load. The dual-carbon/ceramic mechanical seal with Viton O-rings holds pressure at ≥1.8 bar for 10 minutes — critical because coolant system pressure in these engines peaks under full load at high ambient temperatures. The Viton O-rings carry a 200°C temperature rating, providing margin well above typical coolant operating temperatures.

What Happens When a Variant Mismatch Reaches the Machine

A pump that is dimensionally close but not variant-correct creates two failure paths. The first is immediate: ports do not align, hoses refuse to seat, and the pump goes back in the box while the machine stays down and the return freight clock starts ticking. The second is delayed and worse: the pump bolts on but the impeller sits slightly too far from the volute, reducing flow just enough that coolant temperature creeps upward under load, eventually warping the head or cracking the block. Both outcomes trace back to the same root cause — ordering by base number without serial-level confirmation. [NEED_CITE: coolant flow deficiency effects on diesel engine cylinder head integrity]

Why Sourcing Through This Channel Reduces Fitment Risk

Our own production lines and qualified sourced supply carry identical QC standards and a single warranty, so you do not track which batch came from which source. The eight-category catalogue means a complete cooling system refresh — pump, thermostat, hoses, coolant filters — ships as one consignment rather than splitting across multiple suppliers with mismatched lead times. We hold stock in our Guangzhou warehouse for fast dispatch on common items. Identification works from part number, machine model, photograph, or nameplate image. Cross-reference verification covers both the 4131A062 and the superseded 4225069M91 number against service documentation, not copied third-party tables. A single sample unit is available for bench fitment before you commit to fleet-level quantities. Our technical team confirms compatibility and variant matching within hours of receiving your engine serial or pump photograph.

Documentation & Verification

• Commercial invoice and packing list referencing engine serial and variant confirmed
• Fitment and cross-reference sheet for 4131A062 and 4225069M91 (reference only)
• Dimensional check on port spacing and shaft runout before dispatch
• 6-month warranty terms with 12-month extension available per application
• Packing photographs showing anti-rust coating and foam protection
• HS code and customs documentation support for international shipments

Fitment Check Before Installation

• Compare inlet and outlet port clocking positions between old and new pump before removing the old unit from the block
• Verify gasket mating surface is clean and free of old sealant residue to maintain the Ra 0.8 μm finish contact
• Check shaft seal engagement depth and confirm the Viton O-rings seat without pinching
• Hand-rotate the impeller to confirm free movement and ≤0.03 mm shaft runout before torquing flange bolts
• Pressure-test the assembled cooling system to 1.8 bar minimum to validate the mechanical seal before returning to service

Confirm Your Variant Before Placing an Order

Send us the engine serial number from the Perkins data plate, the full machine model, or a clear photograph of the existing pump showing port orientation and flange pattern. If the nameplate is gone, a photo of the block casting number and the old pump from two angles is enough for our team to verify the correct variant and issue a cross-reference sheet for your records.

Frequently Asked Questions

Q: How do I confirm this pump fits my specific engine serial variant? A: Send the engine serial number from the Perkins data plate. Our technical team cross-references it against documented variant differences in port position, gasket profile, and impeller configuration across the 1104A-44 through 1104D-44TA range, then confirms fitment before you commit to an order.

Q: My old pump has a different number — is 4131A062 a valid replacement? A: The 4225069M91 number is a verified superseded reference for this pump. Send us the number cast or stamped on your existing unit and we will confirm whether it maps to the same variant interface. Never rely on cross-reference tables copied between sellers without independent verification.

Q: Why does the same base number show up with slightly different configurations? A: The Perkins 1104 family evolved across multiple sub-generations — 1104A, 1104C, 1104D — with machining changes to the block water jacket opening at each transition. The base identifier remained the same while port positions and gasket surfaces shifted, making serial-level confirmation essential.

Q: I only have the machine model, no readable part number — can you still identify the right pump? A: Yes. Provide the machine model such as Massey Ferguson 5460 or Landini Rex 105F along with any visible engine markings. We cross-reference against known build configurations and, where ambiguity remains, ask for photographs of the old pump mounting face and port orientation to narrow the variant.

Q: Can I get a sample to test fit before ordering in bulk? A: A single sample unit ships for bench fitment against your engine block. This lets you verify port alignment, flange pattern, and hose routing in your specific machine configuration before committing to fleet-level quantities for a rebuild program.
