Product Description
As a professional Caterpillar turbocharger manufacturer, Elecdurauto provides the T1238 heavy-duty turbocharger as a perfect OEM replacement for 6N7203 and 0R5841. Engineered for Caterpillar D8K and 583K with the D342 engine, this model ensures consistent boost performance, superior durability, and precise fitment for industrial-grade applications in mining, pipeline, and construction equipment.
Elecdurauto is more than a heavy-duty turbocharger manufacturer — it's a trusted partner for global distributors and construction equipment operators who demand durability, precision, and consistency. The turbocharger is built to perform under the toughest earth-moving and pipeline installation conditions, ensuring continuous power and reliability on site.
Elecdurauto's production base is purpose-built for construction-grade turbochargers.
Over $45 million USD invested in automated casting, CNC machining, and balancing lines.
Annual output: 1,000,000+ complete turbos and 2,000,000 CHRA units.
Equipment sourced from the US, Germany, Japan, and Switzerland, ensuring OE-level precision.
Each T1227 turbo undergoes dynamic VSR balancing and endurance simulation testing to replicate Caterpillar's real-world operating conditions.
The D8H turbocharger is engineered for the harshest earth-moving environments.
Uses Inconel turbine wheels and reinforced bearing systems to handle extreme vibration and heat.
Tested for 950°C–1100°C thermal stability and long-cycle durability under heavy load.
Boosts engine torque and fuel efficiency while reducing emissions — optimized for sustained performance in construction and mining.
Every Elecdurauto Caterpillar D8H turbocharger is built under globally recognized quality systems.
Certified to IATF 16949, ISO 9001, CE, and RoHS standards.
Each unit is traceable via QR code and digital batch records for full lifecycle tracking.
Includes free quality inspection reports and 1-year unlimited mileage warranty for complete buyer confidence.

From full turbo assemblies to individual CHRAs and core components, Elecdurauto delivers complete support to global B2B partners.
Yes. The Elecdurauto T1238 turbocharger directly replaces OEM 6N7203 and 0R5841 units used on Caterpillar D8K and 583K machines with the D342 engine.
No modification or adapter is required during installation.
The T1238 delivers improved boost pressure, better fuel combustion, and lower exhaust temperatures, resulting in:
More consistent power under load
Reduced black smoke emission
Extended engine life due to cleaner combustion
Check your existing turbo's data plate for:
Turbo P/N: 465032-0001
OEM NO.: 6N7203 or 0R5841
If your current turbo matches these numbers and your machine runs a D342 engine, the T1238 is a perfect fit.
Under proper maintenance and clean oil supply, the T1238 turbo typically lasts as long as OEM Garrett units, with over 5,000–7,000 working hours in earth-moving environments.
It's recommended to inspect or replace them to prevent contamination. A new turbo with dirty oil lines can cause bearing failure within hours.
Yes. Upon request, Elecdurauto provides a detailed installation guide including torque specs, oil priming procedure, and break-in recommendations for D342 engines.
Change engine oil and filter every 250 hours
Clean or replace air filters frequently
Avoid sudden shutdown after heavy use (let the turbo cool down)
No. Every Elecdurauto turbocharger is factory-balanced and flow-calibrated. You can install it straight out of the box.
Yes.
Complete Turbo Assembly: P/N 465032-0001 (Material Code: 200001180047)
CHRA Core: P/N 407505-0014 (Material Code: 300001180817)
