The 318632 S400 Turbocharger Replacement is engineered for use in various Komatsu diesel engine applications commonly found in heavy-duty industries.
Because Komatsu engines are used across multiple machine platforms, customers are strongly encouraged to verify turbocharger part numbers, engine models, and equipment specifications before ordering.
The S400 turbocharger is specifically designed to withstand harsh environmental conditions and extended operating cycles.
The compressor wheel is engineered to optimize airflow delivery into the engine, improving combustion efficiency and power generation.
Benefits include:
The turbine housing is manufactured from heat-resistant materials capable of handling extremely high exhaust gas temperatures generated during heavy-duty operation.
This helps:
Turbocharger shaft assemblies operate at extremely high rotational speeds. Every 318632 S400 turbocharger is dynamically balanced to reduce vibration and improve reliability.
Advantages include:
The journal bearing system provides stable lubrication and long operational life for demanding industrial applications.
Proper lubrication helps:
Turbocharger reliability heavily depends on proper lubrication. Dirty oil, oil starvation, or contaminated oil lines are among the most common causes of turbocharger failure.
Before installation:
Foreign object damage can severely damage compressor wheels and turbine assemblies.
Always inspect:
for contamination or debris before installation.
Before initial startup, pre-lubricate the turbocharger using clean engine oil to prevent dry startup conditions.
Failure to properly prime the turbocharger may result in premature bearing damage.
Heavy-duty diesel engines generate extremely high exhaust temperatures during continuous operation.
Operators should:
These practices help maximize turbocharger service life.
A failing turbocharger may produce several noticeable performance problems.
Ignoring these symptoms may lead to further engine damage and costly repairs.

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.
