FAQs

Q1: How do I confirm if this GT2556S turbo fits my Perkins generator? 

Please check the nameplate on your current turbocharger for the part number 2674A404 or 879657-5001S. Since Perkins engines have many build variations, confirming the 8-digit Perkins part number is the most reliable method. If unsure, provide your Engine Serial Number (ESN) to our support team for a free fitment audit.

Q2: Is this turbocharger built for 24/7 continuous operation? 

Yes. We use genuine K18 nickel-alloy wheels and heavy-duty bearing housings designed to handle the constant load and heat associated with Prime and Continuous power generation modules.

Q3: What are the benefits of choosing Zhongke’s turbo for my Genset? 

Stability is key for generators. Our turbochargers undergo VSR high-speed balancing to ensure they deliver smooth, vibration-free boost, which protects your engine components and ensures a stable power output.

Q4: What type of warranty do you provide for industrial power units? 

As a direct manufacturer with nearly 30 years of experience, we stand behind our quality and provide full technical support for power plant managers and maintenance teams worldwide.

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.
