How to Check an Excavator Final Drive Nameplate

1. Why the nameplate matters

The same excavator model can leave the factory with different final drive configurations across serial ranges and markets. A model name alone is not an identifier. The nameplate on the drive itself — together with the machine serial number — is what separates a confident match from an expensive guess.

2. Where to find it

• On most excavators the final drive sits inside the track frame at the rear of each side, behind the drive sprocket.
• The nameplate is usually a small metal tag riveted or stuck to the drive housing — often on the outer face of the gearbox or on the travel motor casing.
• Expect grease and mud. Clean the area with a rag and degreaser; a wire brush helps on corroded tags. Do not sandblast or grind the plate.
• If the plate is missing or illegible, photograph the mounting face, the sprocket interface and the motor ports instead — bolt pattern and port layout still narrow the identification.

3. What to record

4. Photo checklist

1. Whole machine from the side (shows model and configuration).
2. The machine ID plate with the serial number, in focus.
3. The final drive nameplate, close and sharp — wipe it first.
4. The mounting face / sprocket side of the old drive.
5. The travel motor port side, if visible.

Tip: shoot in daylight, tap to focus on the stamped characters, and take one angled shot — stamped text often reads better with shadows.

5. Send it with your RFQ

Attach the photos to your quote request together with any part numbers you have. We confirm the match technically — catalog cross-references, serial breaks and the nameplate — before anything is ordered.
