High-Performance 174193 S200AG047 Turbocharger for Caterpillar 3126 & C7 Diesel Engines

The 174193 S200AG047 turbocharger is a durable and high-efficiency turbocharger designed for GMC trucks and Caterpillar diesel engines, including the CAT 3126 and CAT C7 engine series. Engineered for demanding commercial and industrial applications, this turbocharger delivers reliable boost pressure, improved fuel economy, strong low-end torque, and long-lasting durability under heavy operating conditions.

For diesel engine rebuilders, fleet maintenance companies, heavy-duty truck operators, and aftermarket turbocharger distributors, the S200AG047 turbocharger provides a dependable replacement solution that restores engine performance and improves operational efficiency.

Whether used in medium-duty GMC trucks, commercial transport fleets, construction equipment, or industrial diesel applications, the 174193 turbocharger is built to support stable engine operation and maximize productivity.


Why the S200AG047 Turbocharger Matters

Turbochargers play a critical role in modern diesel engine performance. By compressing intake air and increasing oxygen flow into the combustion chamber, the S200AG047 turbocharger helps engines produce more power while maintaining efficient fuel consumption.

For CAT 3126 and C7 engines commonly used in trucks and industrial equipment, maintaining proper turbocharger performance is essential for:

  • Engine power output
  • Fuel economy
  • Exhaust efficiency
  • Load carrying capacity
  • Emission performance
  • Engine longevity

A worn or damaged turbocharger can lead to reduced power, excessive smoke, increased fuel consumption, and even severe engine damage if not replaced promptly.

The 174193 S200AG047 turbocharger is designed as a reliable replacement option to restore engine efficiency and operational reliability.

Frequently Asked Questions

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:

  • CHRA (Core Assemblies): Complete cartridge core units for various turbo models.
  • Turbine Wheels & Shafts: Turbine wheel-and-shaft assemblies available in different sizes and materials.
  • Compressor Wheels: High-precision compressor wheels made from durable high-strength alloys (aluminum or even titanium, depending on the application).
  • Bearing & Seal Kits: Overhaul kits with journal bearings, thrust bearings, seals, and rings for rebuilding turbos.
  • Actuators & Components: Wastegate actuators (mechanical) and electronic actuators, plus related small parts.

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:

  • Improper Installation or Misuse: If the part was installed incorrectly or used incorrectly — e.g. not priming the turbo with oil before startup, wrong gaskets, misassembly.
  • External Factors (Oil Starvation or Contamination): Failures caused by inadequate or dirty oil (e.g. blocked feed lines or poor oil quality).
  • Foreign Object Damage: Debris entering the turbo (intake or exhaust) and damaging parts.
  • Operating Outside Design Limits: Engine or turbo run beyond design parameters (overspeed, excessive exhaust temperatures, etc.).
  • Normal Wear and Tear: Gradual wear of consumables (e.g. seals) under regular usage.

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.
