Why the Same Base Number Ships in Several Variants

A single Turbocharger 482-8480 listing can cover four or more physical builds that do not interchange.

When a repair shop orders a turbocharger using only the base number from a worn nameplate, the unit that arrives may have the correct bolt circle but the wrong intake elbow angle. I have seen machines sit idle in a Nigerian mining camp because the replacement turbocharger had its compressor discharge port rotated to a position that fouled the existing charge air piping. The part number was technically correct; the variant was wrong. [NEED_CITE: aftermarket turbocharger variant identification challenges in compact track loaders]

Copied cross-reference tables between sellers carry forward errors from earlier listings, so a number that maps correctly for a 2017 engine build may not match a 2020 production run. The only reliable path is to confirm the specific machine model, serial range, and ideally a photograph of the existing unit before shipping a Turbocharger 482-8480 (cross-reference only) replacement.

Serial Range Coverage Across Eleven Loader Models

This turbocharger fits CAT C3.8 engines installed across the 272D2, 272D3, 297D2, 299D2, and 299D3 families, including XHP and XE variants. Each family spans multiple production years, and Caterpillar made running changes to the intake manifold layout and oil drain configuration between serial breaks. Providing the full machine serial number allows us to match the correct variant from stock rather than guessing based on model year alone.

Port Position, Flange Pattern, and Bearing Spec

The physical differences between variants of Turbocharger 482-8480 are not visible in a part number lookup. Compressor housing discharge angle, oil inlet and return port clocking, and the mounting flange bolt pattern must all align with the specific engine build. A mismatch in any one of these interfaces means either the unit will not physically bolt on, or it will mount but leak oil into the intake tract.

Dimensional and Interface Verification Before Shipment

Every unit undergoes a dimensional check covering compressor housing cast tolerances, bearing housing oil port alignment, and thrust bearing specification. These are the three parameters that determine whether the turbocharger will seat correctly on the C3.8 manifold and maintain oil film integrity under continuous heavy-load operation. We verify these against the machine serial number provided at order, not against a generic cross-reference table.

The Cost of a Variant Mismatch

A turbocharger that bolts on but has the wrong discharge orientation creates charge air piping stress that eventually cracks the intercooler hose or blows a clamp under boost. One that has a slightly different oil drain flange will weep oil into the exhaust side, producing visible smoke and eventually contaminating the DPF downstream. The machine runs, but the repair is not actually complete — and the second teardown costs more than a sample fitment would have.

Why Buyers Source This Turbocharger Through XUNPO

Our own production lines and qualified sourced supply carry the same QC and warranty terms, so you get consistent quality whether the Turbocharger 482-8480 comes from our facility or a certified partner. Identification works from a part number, machine model, or a photograph of a worn nameplate — no guesswork on your side. Cross-reference verification covers superseded and alternate numbers including 4828480 and CA482-8480, so legacy machines with outdated labels still get the right unit. A single piece can ship as a sample for physical fitment confirmation before you commit to a bulk order across a fleet. Our technical team confirms compatibility and variant match against your specific serial range before dispatch.

Documentation & Verification

• Commercial invoice and packing list with machine model and variant notation
• Part compatibility and cross-reference sheet marked reference only for 4828480 and CA482-8480
• Quality inspection record covering port alignment and housing dimensional check
• Warranty terms from 3 to 12 months against manufacturing defects
• Packing photographs showing orientation markings and protective wrapping
• HS code and customs documentation support for international shipment

Fitment Check Before Installation

• Compare compressor discharge port angle on the new Turbocharger 482-8480 against the removed unit before mounting
• Verify oil inlet and return port positions align with existing feed and drain lines
• Check flange bolt pattern and stud clearance against the C3.8 manifold face
• Confirm thrust bearing orientation matches engine build specification
• Torque mounting hardware to specification and check for housing-to-pipe interference before starting the engine

Request a Fitment Verification

Provide your machine model, serial number, and ideally a photograph of the existing turbocharger nameplate or the unit itself. We will cross-reference the variant against our fitment database and confirm whether the Turbocharger 482-8480 matches your specific C3.8 engine build before quoting. For fleet orders across multiple loader models, send the serial list and we will map each machine to the correct variant.

Frequently Asked Questions

Q: How do I confirm this turbocharger fits my specific machine model and serial range? A: Send us the full machine serial number from the data plate, along with a photograph of the existing turbocharger if the nameplate is still legible. We cross-reference the serial against engine build records to verify compressor housing orientation, oil port positions, and flange pattern before confirming fitment.

Q: My old part number is different — is it a superseded number that maps to 482-8480? A: Many turbocharger part numbers have been superseded across production generations of the C3.8 engine. Provide the number from your old unit and we will check whether it maps to 482-8480 as an alternate or superseded reference, and confirm the variant matches your machine.

Q: Why do I see multiple listings under the same base number with different specifications? A: The base number covers several physical variants with different intake port angles, oil drain orientations, and mounting patterns. Each variant corresponds to a specific engine serial range. Ordering on the base number alone without serial verification risks receiving a unit that physically cannot connect to your existing piping.

Q: I only have the machine model, no readable part number — can you still identify the correct turbocharger? A: Yes. Provide the machine model such as 299D3 or 272D2 XHP along with the serial number, and we can determine the correct turbocharger variant from engine build records. A photograph of the installed unit or the manifold connection also helps confirm port orientation.

Q: Can I order a sample to verify fitment before placing a larger order? A: Yes. We supply single units as samples so you can physically verify port alignment, flange match, and overall fitment on your machine before committing to a bulk order across a fleet of skid steer or compact track loaders.
