Why does my final drive become slow after warming up?

Does your excavator travel normally when cold, then slow down after it warms up? That detail matters. A heat-related change can be associated with internal leakage or another hydraulic condition, but the symptom alone is not enough to identify the failed component. Continuing to guess can waste time and parts. Record how long the machine runs before the problem starts and whether other functions change at the same time. Send those details, the make and model to Arena by DM for assessment guidance.

One excavator track moving slower than the other does not automatically mean the final drive has failed. Track tension, undercarriage resistance and hydraulic issues can create a similar symptom. Before replacing parts, note whether it happens cold or warm, travelling straight or turning, and with or without load. That information gives the workshop a much better starting point. Send Arena a DM with the machine make, model and a short video of the problem for the next step.

Could this Hitachi ZX260-5 final drive be repaired—or was replacement the smarter option?

When the unit arrived at Arena’s Hallam workshop, the gearbox had completely failed. Sam’s inspection revealed a worn gearbox shaft, a worn hydraulic-side shaft, and bearings and gears that were no longer serviceable.

Instead of automatically replacing the complete final drive, Sam identified a more economical solution: retain the serviceable hydraulic section and install it into a replacement gearbox.

For this customer, that approach saved approximately $3,500 compared with replacing the complete final drive.

Watch the video to see the damaged components and the replacement gearbox Sam selected for the rebuild.

When was the last time you checked the sprocket beside the final drive? Wear in the undercarriage can change how forces are transferred through the track system. A new or repaired drive should not be treated as an isolated component while the surrounding wear is ignored. Inspect the sprocket and track condition as part of the wider maintenance check, following the machine manufacturer’s limits. Save this post for your next undercarriage inspection. 🕣 8:30am to 5:00pm

This Sumitomo SH235 swing device had completely stopped working, but the failure wasn’t limited to just one section.

When the unit arrived at Arena’s Hallam workshop, Sam carried out a detailed inspection and discovered problems on both the hydraulic and gearbox sides. Several internal components had failed, while heavily worn and deformed seals had caused a hydraulic oil leak.

Sam fully disassembled the unit, replaced the damaged shafts, seals and other necessary parts, and thoroughly cleaned the remaining components to prevent dust or contamination from entering the hydraulic system.

After reassembly and fresh hydraulic oil, the swing device was tested on Arena’s test bench. Once Sam confirmed that every section was operating correctly and working in sync, the unit was ready to return to the customer and go back into service.

Watch the full video to see what Sam discovered and how the swing device was rebuilt and tested.

Save these questions before requesting your next quote.

"New, aftermarket, reconditioned or used final drive. which should I buy?"

New, aftermarket, reconditioned or used, those labels do not tell you everything about a final drive. Ask what is included, how compatibility is checked, what testing has been completed, what the warranty covers and whether parts support will be available later.
Also compare the cost of freight, installation and possible downtime, not only the unit price.

For an Arena product enquiry, send the machine details by DM or visit the link in our bio.

No readable part number on the final drive? Don’t order by appearance alone. Start with the exact machine make, model and serial details. Then take clear photos of the complete unit, mounting face, sprocket side, hydraulic ports and any remaining markings. These details can help narrow down the correct configuration. Save this checklist for your next parts enquiry, or send the details to Arena by DM for identification support.
