Frequently Asked Questions (FAQ)

Product Selection

Q: What types of turbocharger spare parts do you offer?

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.

Q: How can I ensure I choose the correct part for my turbocharger?

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.

Q: Is there a minimum order quantity, or can I order samples for testing?

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.

Warranty Policy

Q: What is the warranty on your turbocharger spare parts?

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.

Q: What does the warranty cover and what are the exclusions?

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.

Performance Specifications

Q: Are your aftermarket spare parts as reliable as the original OEM parts?

Absolutely. Our aftermarket turbocharger spare parts are engineered to meet or even exceed OEM performance and reliability. We partner with experienced manufacturers who use high-grade materials equivalent to OEM standards. For example, our turbine shafts and wheels use heat-resistant alloys; our compressor wheels are precision-machined from strong aluminum or titanium alloys.

We also ensure all parts match OEM specifications in design and dimensions, so when you install one, it fits and works like the original. Many professional turbo remanufacturers already use our parts for their reliability. In short, when installed correctly, your turbo should deliver the same boost performance, efficiency, and endurance as with the OEM component.

Q: How do you ensure the quality and performance of each part?

We maintain rigorous quality control for every part. During production, critical components go through precision machining to achieve exact tolerances. For rotating parts — CHRAs, turbine shafts, compressor wheels — we perform high-speed balancing tests. Every CHRA, for instance, is balanced on a VSR (Vibration Sorting Rig) at operational RPM to minimize vibration and extend bearing life.

We also measure dimensions carefully, verify clearances and seals, and inspect each part for material or machining defects before packaging. We even sample-test batches (e.g. journal bearings) for hardness and accuracy. Our processes align with strict automotive industry standards, ensuring that each part shipped has passed multiple quality checks. You can trust that when you receive it, it’s ready for reliable performance in your turbo rebuild.

Troubleshooting

Q: Do you provide technical support if we encounter issues during installation or operation?

Yes — we’re here to help. If you run into problems during installation or after the turbo is operating, our team is available. We have engineers experienced in turbo assembly and common failure modes.

If your rebuilt turbo doesn’t deliver expected boost or makes odd noises, reach out. We’ll guide you through symptom diagnosis — checking oil flow, actuator calibration, or engine-side factors that may affect turbo performance.

We understand time is valuable for remanufacturers and repair shops, so we’ll respond promptly with actionable advice. If it seems one of our parts might be at fault, we may request detailed photos or descriptions, and examine the part if needed. Our goal is to support you until things run smoothly.

Q: What are common causes of turbocharger failure, and how can they be prevented?

Turbocharger failures can result from many causes — and often the fault is not the part itself. Being aware of common causes can help prevent them:

• Oil Starvation or Contaminated Oil: Lack of clean, pressurized oil leads to bearing wear or seizure. Always maintain proper oil level, use recommended oil, replace filters, ensure feed lines are free, and prime the turbo before startup.
• Foreign Object Ingestion: Debris entering the compressor or turbine side can damage blades. Clean intake/exhaust paths, ensure good filter condition, and inspect manifolds/intercoolers before installation.
• Improper Installation: Mistakes such as not priming the turbo, reusing gaskets, misalignment, or improper tightening can cause early failure. Follow proper procedures: pre-oil the turbo, use new gaskets, align lines correctly, and let engine idle initially.
• Extreme Operating Conditions: Running the engine or turbo beyond design limits (overspeed, excessive temperatures, frequent hot shutdowns) strains components. Keep operations within design specs, avoid aggressive tuning unless turbo is rated, and allow cooldown after heavy use.
• Underlying Engine Issues: Sometimes a failing turbo is only a symptom. Problems like clogged DPF, exhaust restriction, engine leaks, or combustion issues can stress the turbo. Always investigate the engine system as a whole and fix root causes.

By managing oil quality, correct installation, conservative operation, and addressing engine-side problems, you can greatly extend turbo life. When you rebuild using our parts, we’re glad to provide best-practice guidance to help you maximize durability.

Shipping and Return Policy

Q: Do you ship internationally? What shipping methods and trade terms do you offer?

Yes, we ship globally. We generally use standard Incoterms — defaulting to EXW (Ex Works) or FOB (Free on Board) from our facility. Under EXW/FOB, we either make goods available at our location or deliver them to your appointed forwarder at the port. If needed, we can also work with terms like CFR, CIF, DAP, or DDP — just let us know your preference.

Shipping options depend on urgency and order size:

• Express Courier (Air Express): For small or urgent orders (e.g. DHL, FedEx, UPS). Delivery typically takes 5–10 days globally.
• Air Freight: For medium shipments, air cargo to your nearest airport (5–10 days plus customs clearance).
• Sea Freight: For large or bulk orders, sea is more economical — transit typically 3–6 weeks depending on destination.

You may use your own forwarder or let us recommend one. We pack items securely (cartons, padding, pallets/crates) and handle export documentation (commercial invoices, packing lists, etc.). Note: under most Incoterms, import duties or taxes at arrival are the buyer’s responsibility — unless we agree otherwise (e.g. DDP). We coordinate shipping to fit your needs.

Q: How long does it usually take to process and deliver an order?

Processing time depends on stock status:

• In-Stock Items: Typically shipped within 3–5 business days after payment confirmation and order details finalized.
• Out-of-Stock / Made-to-Order: Usually requires 2–4 weeks for production or procurement; we’ll inform you of the lead time.

Once shipped, delivery time depends on method: express (~1 week), air freight (1–2 weeks incl. customs), sea freight (3–6 weeks). We’ll provide tracking or bill of lading so you can monitor shipment.

Q: What if my order is damaged during shipping?

We pack carefully (foam, bubble wrap, crates/pallets) to minimize damage risks. Once the package is in carrier hands, responsibility depends on the agreed Incoterms. Under EXW/FOB, risk passes to buyer once goods are handed over to the carrier.

We strongly recommend you insure the shipment, especially for high-value or fragile parts. Insurance covers unforeseen damage during transit.

If you receive a damaged package: document everything (photos, notes on delivery receipt). Contact the carrier immediately to initiate a claim, and also inform us. While transit damages may fall under carrier responsibility per the shipping terms, we’ll assist you with paperwork and communication to help resolve it.

Q: What is your return and exchange policy for spare parts?

We understand returns may sometimes be needed, and we aim to be reasonable. Here's how we handle them:

• Wrong / Defective on Arrival (DOA): Notify us within 7–14 days. We'll verify and arrange replacement or refund, and cover return shipping for the wrong/defective item.
• Ordered the Wrong Part: Contact us promptly. If the part is unused and in original condition, we may accept exchange. Buyer typically covers return shipping; a restocking fee may apply depending on situation, which we’ll communicate in advance.
• Other Cases (Project Changes, etc.): If non-defective items need return due to changed plans, get in touch. We don’t usually offer open-ended returns for non-defective parts (especially given international shipping costs), but will consider reasonable requests case by case. Possible solutions include limited returns or credit toward future purchases.

In all cases, please **obtain Return Authorization** from us before sending anything back. This ensures we can track and process the return properly. Our goal is to resolve issues in good faith — whether by replacement, refund, or other arrangement. We want you to feel confident we’ll treat you fairly and work through any problems together.
