FAQs

Q1: How do I verify if this RHF4 turbocharger fits my Shibaura tractor or CAT loader? 

Please check the nameplate on your current turbocharger's compressor housing for the part number 135756180 or 238-9349. Since the N844L engine is used by multiple brands (Shibaura, Cat, New Holland), matching the specific 9-digit or 7-digit OEM part number is the most reliable way to ensure a correct fit.

Q2: Is this turbocharger compatible with the Caterpillar 238-9349 / 10R-9578 Reman unit? 

Yes. This unit is a direct "drop-in" replacement for the CAT 238-9349 and the remanufactured 10R-9578. It is manufactured to the same precise dimensional and performance specifications as the original factory unit, making it ideal for CAT-powered loaders.

Q3: What are the primary maintenance tips for agricultural turbochargers? 

Since farm work involves high levels of dust, ensure your Air Filter is replaced regularly. Additionally, always use high-quality engine oil and allow the engine to idle for 2-3 minutes before shutting down after heavy use. This prevents "coking" in the bearing housing and significantly extends the turbo's life.

Q4: What type of warranty do you provide for heavy-duty agricultural use? 

We understand that agricultural machinery often operates in high-dust and high-vibration environments during planting and harvest seasons, which is why we stand behind our quality with full technical support for our global customers.

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.
