FAQ

Q1: How do I confirm this crankshaft will fit my engine?

First, verify that your engine is a Quanchai 4D26 model. Then, locate the part number on your old crankshaft. The primary number to match is 2409000500401. If your existing part number matches this, the part is a direct fit. If you are unsure, please contact us with your engine serial number and old part number for verification.

Q2: What other parts should I replace when installing a new crankshaft?

For a professional rebuild, it is strongly recommended to replace the following components simultaneously: main bearings, connecting rod bearings, thrust washers, and front/rear crankshaft oil seals. This ensures proper oil clearance and prevents future leaks. The crankshaft itself is ready to install, but these associated wear items should be renewed for maximum engine life.

Q3: What is the lead time for international orders?

Lead times vary based on stock levels and shipping destination. Typically, orders are processed within 1-3 business days. For express courier services (DHL/FedEx), delivery to major international cities usually takes 5-10 business days. Sea freight to major ports typically takes 20-35 days. We recommend contacting us for a precise lead time quote based on your location and preferred shipping method.
