FAQs

Q1: How do I verify fitment for my EC700B excavator? 

Please check the nameplate on your current turbocharger for the part number 2839679 or the Volvo number 11053884. Since the MD16 series has several Tier configurations, matching these numbers is the only way to ensure 100% compatibility.

Q2: My old turbo part number is 4031134H. Is this the same? 

Yes. The "H" or "HX" suffix indicates a Holset service or exchange unit. Our 2839679 is the latest-revision, brand-new direct replacement for these numbers, providing improved internal seals and bearing longevity.

Q3: Does the turbo include the heavy-duty gasket kit? 

Yes. We typically include a high-temperature mounting gasket kit to ensure a perfect, leak-free seal for the oil and exhaust connections. We strongly recommend using new gaskets for these high-displacement engines.

Q4: What is the most important installation tip for Volvo 16L engines? 

Cleanliness and Pre-Lubrication. Before starting the engine, fill the oil inlet of the new turbo with fresh engine oil and rotate the shaft by hand. On 16L engines, we also recommend replacing the Oil Feed Line to ensure the heavy-duty HE551W bearings receive maximum lubrication immediately.

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.
