ORDERING THE RIGHT EXCAVATOR FINAL DRIVE THE FIRST TIME: THE INFORMATION CHECKLIST

ORDERING THE RIGHT EXCAVATOR FINAL DRIVE THE FIRST TIME: THE INFORMATION CHECKLIST

The most expensive final drive is the wrong one. When a travel motor is shipped, installed, and only then found to be a mismatch, you lose the part cost, the return shipping, the labor, and days of downtime. Almost every one of these mistakes traces back to incomplete information at the moment of ordering. This guide gives you the exact checklist to send Belparts so you get the correct final drive the first time.

Why "Send Me the Model" Is Not Enough

Two identical-looking excavators of the same model and year can carry different final drives. Manufacturers change suppliers mid-production, offer two-speed and single-speed options, and update spline counts or bolt patterns across production runs. Any supplier that ships a drive based only on "Cat 320, 2015" is guessing — and you are carrying the risk of that guess.

The fix is simple: give Belparts enough data points that only one part number can possibly match.

The Core Ordering Checklist

Send every item below that you can gather. The more you provide, the tighter the match

1. Final drive data tag
   Get under the machine and photograph the tag on the drive itself. It often carries the OEM part number and the drive manufacturer's own code — the most direct route to an exact match.
2. Motor / drive part number (if legible)
   Sometimes stamped on the housing separately from the tag. Even a partial number narrows the field dramatically.
3. Single-speed or two-speed
   Count the hydraulic ports on the old drive. A two-speed drive has an extra port (and line) for the speed-shift signal. Fitting a single-speed where a two-speed belongs — or vice versa — causes travel and speed faults.
4. Mounting bolt holes & pattern
   Photograph the mounting flange straight-on. Bolt-hole count and spacing must match the machine frame perfectly.
5. Sprocket details
   State whether you need the drive with or without a sprocket, and count the sprocket teeth. Photograph the sprocket bolt pattern as well.
6. Hydraulic port configuration
   Photograph the port face — number of ports, thread type, and their layout. This confirms the exact motor variant.

The Photo Set That Prevents 90% of Mistakes

Words get mistranslated; photos do not. Send this standard photo set with every inquiry to Belparts:

• The data tag on the final drive (close-up, in focus, all characters readable)
• The mounting flange face, shot straight-on
• The hydraulic port face, showing all ports clearly

Our team at Belparts can identify the correct unit from this set even when the tag is partly worn or faded.

What to Confirm Back From Belparts

Before you approve the order, our team will confirm all of the following in writing:

• The exact OEM part number(s) the unit replaces
• Whether it is new, remanufactured, or aftermarket specification
• Whether a sprocket is included
• Single-speed or two-speed configuration
• The warranty period and coverage details

If a supplier cannot answer these clearly, that is a warning sign — not a bargain. At Belparts, full transparency on every order is our standard.

A Note on Aftermarket Cross-References

Aftermarket suppliers often list one unit as fitting several OEM numbers. That is normal and usually fine — but at Belparts, we never stop at just "model fit". We always verify that your specific machine configuration falls within the fitment range, not just your general model. Fitment ranges have gaps, and we make sure your unit is a precise match.

Quick Pre-Order Checklist

• Final drive data tag photographed
• Single- vs two-speed confirmed (via port count)
• Bolt-hole pattern photographed
• Sprocket teeth counted, with/without specified
• Port face photographed
• Belparts has confirmed OEM number, condition, warranty, and core terms in writing

The Bottom Line

Ordering the right final drive is not luck — it is good information. Spend fifteen minutes under the machine gathering the data tag, port details, and a clean photo set, and you eliminate almost every cause of a wrong-part shipment. At Belparts, we welcome this level of detail because it protects both you and us.
