Product Description

K03 Turbo 7256748 53039880659 Turbocharger for Skid-steer Loader D34 Engine

Replacement K03 turbocharger for D34 diesel engines, compatible with S740, S750, S770, S850, T740, T750, T770, T870 and A770 loaders. Replaces 7256748, 150105-00344 and 53039880659. Designed for reliable boost response, stable engine power and demanding skid-steer loader applications.

Product Overview

High-Performance K03 Turbocharger for Skid-Steer & Compact Track Loaders

  • Designed for the D34 Engine: This K03 turbocharger is developed as a replacement for the turbocharger used on D34 diesel engines. It helps restore proper boost pressure, engine response and working power on loaders used for construction, landscaping, agriculture and material handling.
  • Suitable for Heavy Loader Work: Skid-steer and track loaders often operate under sudden load changes when digging, lifting or pushing. This turbocharger is designed to provide steady airflow during these working conditions, helping the engine maintain consistent performance when hydraulic demand increases.
  • Direct Replacement Design: The turbocharger is manufactured to match the original mounting position, oil connections and air outlet arrangement used on the listed D34 applications. Always compare the original turbocharger, part number and mounting details before ordering.
  • Stable Boost Response: The K03 design provides a practical balance between low-speed response and airflow capacity. This is important for compact loaders, which require usable torque at low and medium engine speeds rather than power only at high RPM.
  • Suitable for Construction and Agricultural Equipment: The unit can be used for replacement applications across skid-steer loaders, compact track loaders and other equipment equipped with the D34 engine. Replacing a worn turbo can help address low power, slow response, excessive smoke and unusual turbo noise caused by turbocharger wear.

Frequently Asked Questions (FAQs)

Q1: Does this turbocharger fit all S-Series and T-Series loaders?
No. This turbocharger is intended for models equipped with the D34 engine. Model names may use different engines depending on the production year and market. Please compare the engine code and the original turbocharger part number before ordering.

Q2: Can 7256748 replace 53039880659 and 150105-00344?
These numbers are commonly listed for the same K03 turbocharger application. To confirm compatibility, check the identification plate on your original unit and compare the compressor housing orientation, mounting flange and oil line positions.

Q3: What are the common signs that the turbocharger needs replacement?
Typical signs include reduced engine power, slow acceleration, black smoke under load, increased oil consumption, abnormal whistling or excessive shaft play. The air intake, exhaust system, oil supply line and engine condition should also be inspected before replacing the turbocharger.

Q4: What should be checked before installing the new turbocharger?
Replace the engine oil and oil filter, inspect or replace the oil feed line, clean the air intake system and check the intercooler for oil or debris. Prime the turbocharger with clean engine oil before starting the engine, then allow the engine to idle briefly and check for oil, air and exhaust leaks.

Q5: Do you provide worldwide shipping?What is the delivery timeframe?

We ship globally via premium carriers like DHL,FedEx,and UPS,as well as sea freight for bulk orders.In-stock items are typically dispatched within 24-48 hours. Express delivery to North America and Europe usually takes 5-7 business days.
