The 6506-21-5010 KTR90-232E Turbocharger is a premium aftermarket replacement engineered for Komatsu PC400-7 hydraulic excavators powered by the Komatsu SAA6D125E diesel engine. Designed to meet or exceed OEM performance standards, this turbocharger provides reliable air compression, efficient combustion, and consistent engine output for demanding heavy-duty applications.
Turbochargers play a vital role in modern diesel engines by increasing airflow into the combustion chamber. This allows the engine to generate more power while maintaining fuel efficiency and reducing emissions. A worn or damaged turbocharger can lead to power loss, excessive exhaust smoke, poor fuel economy, increased oil consumption, and costly engine damage.
Our 6506-21-5010 KTR90-232E Turbocharger Replacement is manufactured using premium turbine materials, precision-machined compressor wheels, and high-temperature resistant bearing systems. Every unit undergoes rigorous balancing and performance testing before shipment, ensuring dependable performance in construction, mining, quarry, and infrastructure projects.
Whether you are an equipment owner, repair workshop, parts distributor, or OEM replacement supplier, this turbocharger offers an economical and dependable solution for restoring machine productivity.

We provide a wide range of turbocharger spare parts to support both remanufacturing and repairs. Our product lineup includes practically everything you might need. Here are some of the key parts we offer:
These spare parts cover most major turbocharger brands and models for commercial diesel engines as well as passenger vehicles. If you’re looking for something specific, just let us know the turbo model or the OEM part number, and we’ll quickly check if we have it available.
Making sure you get the right part is really important. The best way is to use the original equipment manufacturer (OEM) part number or your turbo’s model number as a reference when you order. Every turbocharger usually has an ID tag or an engraved number on it — if you give us that info, we can find the exact spare part you need.
Our sales engineers are also ready to help. If you let us know your engine model, the turbo’s model (or serial number), and maybe what problem you’re trying to fix or which component you’re replacing, we can cross-check and guide you to the right part. This way you’ll have a correct match and avoid any mix-ups.
We can also provide product catalogs or technical datasheets if you want to double-check the specifications yourself before buying. Just let us know, and we’ll get those to you.
Generally, we don’t have a strict minimum order for our standard parts — you can even order just one piece if that’s all you need. We know remanufacturing shops sometimes want to test a part’s quality first, so small sample orders are totally fine with us.
If you’re looking to buy in bulk, we can certainly discuss volume discounts. The only time we might have a minimum order is if it’s a very specialized or custom-made component, due to the production requirements. In those cases, we’d let you know upfront if any minimum applies.
In most situations, whether you need a single item or a large batch, we’re happy to accommodate. We pride ourselves on being flexible and building long-term relationships with our clients.
We offer a standard 12-month warranty on all our turbocharger spare parts. The clock starts from the date we ship them out, unless we’ve made a different agreement (for example, starting from the installation date in some cases). In short, if any part fails due to a manufacturing defect within those 12 months, it’s covered under our warranty.
If you do encounter a problem that you believe is our fault within the warranty period, just let us know. We’ll typically ask for some details about what happened (maybe a report or photos) so we can understand the issue. Once we’ve confirmed it’s a warranty case, we’ll send you a replacement part or offer you a full refund/credit for that item. We stand behind our products, so if there’s a genuine quality problem, we’ll make it right as quickly as possible.
Our warranty covers failures that result from defects in our parts (materials or workmanship) under normal use. For example, if a compressor wheel had a casting flaw or a cartridge assembly wasn’t balanced properly at the factory and it causes a premature failure, that’s on us and would be covered.
However, there are some situations that are not covered by our warranty. Here are the main exclusions:
In essence, if a part fails because it had a defect, it’s covered. But if it fails due to misuse, external factors, or normal wear, it’s not. If you ever need to claim warranty, we’ll review what happened (often via photos or a failure report) and may examine the part. That ensures we handle claims fairly and transparently.
We will arrange for a specialist to contact you immediately.
