HX25W Turbo 4038790 4089714 Turbocharger for PC128US PC130 PC160 Excavator SAA4D102E Engine
Product Overview
High-Response HX25W Turbocharger for PC128/PC130/PC160 Excavators
- Precision 4-Cylinder Optimization: Specifically engineered for the SAA4D102E and SAA4D95LE 4-cylinder engine platforms. Restores original factory boost response and fuel efficiency essential for the agility and digging power of mid-size excavators.
- Direct "Drop-In" Fit: A 1:1 mechanical match for original Holset HX25W units. Fully compatible with factory air intake manifolds, oil feed lines, and exhaust flanges—ensuring a seamless, zero-modification installation for site mechanics.
- K18 Nickel-Alloy Turbine Wheel: Features a premium K18 Nickel-Alloy turbine wheel, designed to withstand sustained high thermal loads (up to 950°C) common in high-frequency load switching environments without blade deformation.
- VSR Precision Balancing: 100% dynamic balancing tested on a Vibration Sorting Rig (VSR) at full operational RPMs (180,000+). Technical Benefit: This eliminates shaft vibration, ensures whisper-quiet operation, and maximizes the bearing service life in dusty environments.
- Heavy-Duty Wastegate System: Equipped with a pre-calibrated wastegate actuator to prevent over-boost conditions, providing reliable engine protection and a stable torque curve during heavy excavation.

Q1: How do I verify fitment for my PC128US-2?
Please check the nameplate on your old turbocharger for the part number 4038790 or the Holset code 4089714. Since mid-size excavators can have several manifold variations, matching the specific 7-digit number is the only way to ensure 100% compatibility.
Q2: My excavator is losing boost and blowing black smoke. Is it the turbo?
Yes. Black smoke often indicates a boost leak or a worn compressor wheel. Our HX25W ensures your engine receives the precise air-to-fuel ratio, restoring factory digging force and fuel economy while eliminating excess smoke.
Q3: Does the turbo include the required gaskets?
Yes. This unit typically includes a premium industrial mounting gasket kit to ensure a perfect, leak-free seal for the oil and exhaust connections.
Q4: Is this an "Outright Purchase" or a Reman unit?
This is a 100% Brand-New Outright Purchase. No core charge is required, and there is no need to return your old unit, saving you time and international shipping costs.
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.
