How do I make sure a part fits my machine?

Compatibility is our priority. Before ordering, please provide one or more of the following:

🏗️Machine Model & Year
🔖Original OEM Part No.

Email help@liuchuangparts.com or contact us via WhatsApp and our technical team will verify fitment before you order — free of charge.

Q
Are your parts original OEM or aftermarket?

We supply high-quality aftermarket replacement parts that meet or exceed original factory specifications. We are not an authorized OEM dealer and do not sell OEM-branded original parts.

All product listings clearly state the part type and condition. If you have any questions about a specific product, contact us before ordering.

ECM Programming & Technical Support

Q
Do you provide ECM / ECU programming services?

Yes. We provide professional ECM/ECU programming for compatible Caterpillar, Cummins, and Volvo engine control modules. Simply provide your Engine Serial Number (ESN) or software version when ordering, and we will pre-program the unit before shipping so it is plug-and-play when it arrives.

Custom-programmed ECMs are built specifically to your machine and cannot be returned for ordering errors. Please verify your ESN carefully before ordering. If the unit arrives defective, we will replace or refund it in full.

My machine is showing an error code. Can you help?

While we are primarily a parts supplier, our team has extensive hands-on experience with heavy equipment electronics. Contact us via WhatsApp (+86 150 8800 2493) or email with your error code and machine model and we will do our best to provide technical guidance — free of charge.
