Part Number: 3780648 (Holset)
Cross-Reference / Interchange Numbers:

3780649
Also cross-referenced across a large family of related Holset TD02/TD03-series turbos: 3584122 / 3584123, 3786102 / 3786109/3786100 / 3786130, 3788661 / 3788662 / 3788663 / 3788664, 3789166 / 3789167, 3792702, 4031463 / 4031464 / 4031519 / 4031520, and others — these share common internal components (shaft/wheel, heat shield) with 3780648 but are not necessarily direct full-unit substitutes without confirming your specific model

Turbo Model: HX20 (Holset)
Engine/Application: Tractor and generator set (genset) diesel applications

(Note: This part number also appears cross-referenced in some parts catalogs to the TD02/TD03 small-turbo family used on various passenger car and agricultural diesel engines — e.g., listed alongside Hyundai Accent 1.5 TD02 turbo parts. This suggests 3780648 may correspond to a shared internal component (shaft & wheel assembly) used across multiple turbo models rather than being exclusive to one single application. We’d recommend confirming the exact machine/engine this is for before finalizing your listing.)

Product Overview:

This is an HX20 turbocharger from Holset, engineered to OEM specifications for tractor and generator set diesel applications. It restores factory boost pressure and combustion efficiency for engines showing signs of turbo wear — reduced power, excessive smoke, unusual noise, or oil leaks — helping keep agricultural and power-generation equipment running reliably.

Key Features:

OEM-Matched Fitment: Manufactured to match the mounting configuration and flange dimensions of the original 3780648 turbocharger for a direct bolt-on replacement.
Genuine Holset HX20 Platform: A compact, well-established turbo design suited to small-to-mid displacement diesel engines used in tractors and gensets.
Durable Construction: Turbine and compressor components built to withstand sustained heat and pressure cycles typical of agricultural and industrial power equipment.
Restores Lost Power & Efficiency: Addresses common failure symptoms — reduced power, smoke, unusual noise, and increased fuel consumption.
Improved Fuel Efficiency: As with most properly functioning turbochargers, restores optimal air/fuel combustion, helping maintain fuel economy.
Warranty: Typically 1-year manufacturer warranty (confirm specific terms with your supplier/listing).

Before You Buy:

Please confirm the part number stamped on your original turbocharger (3780648 / 3780649) against your exact tractor or genset model and engine serial number, since this part number is referenced across a broad family of related Holset TD02/TD03-series turbos used in different engine applications. Let us know your equipment model and engine details if you’d like help confirming exact compatibility before ordering.
