What Does a Final Drive Rebuild Cost in 2026?
Final drive rebuild cost depends heavily on machine type, brand, and what the tear-down finds inside the case. Below are the actual pay ranges Ames Hydraulics quotes on final drive rebuild work in 2026, broken out by machine category. These are real shop numbers from a shop that rebuilds finals every week.
Final Drive Rebuild Cost by Machine Type
Compact track loader (CTL) final drive rebuild — $2,400 to $4,200
The biggest single category of final drive rebuild work at Ames Hydraulics. CAT 259/279/289/299, John Deere 331G/333G/335G, Bobcat T650/T770/T870, Case TR-series, Kubota SVL-series, Takeuchi TL-series, ASV RT-series all in this range. Final drive rebuild cost includes duo-cone seal replacement, hub bearing service, brake pack rebuild, planetary inspection and matched-set gear replacement if needed, piston motor rebuild, and pressure test on the bench.
Skid steer (wheeled) chain-case final drive rebuild — $1,400 to $2,800
Wheeled skid steers use a different final-drive design — a hydraulic drive motor bolted to the frame that drives the wheels through a chain in an oil-bath case. Final drive rebuild cost covers chain case seals, drive motor rebuild, chain and sprocket replacement if worn, wheel bearings, and axle seals.
Mini excavator final drive rebuild — $2,200 to $4,000
Kubota KX-series, Bobcat E-series, Takeuchi TB-series, John Deere G-series compact excavators, Cat 3-8-ton mini ex. Similar rebuild scope to compact track loaders — the mini ex final drive is essentially a smaller version of the same design. Final drive rebuild cost on mini ex typically runs slightly less than CTL because parts are smaller.
Full-size excavator final drive rebuild — $4,500 to $9,000+
The higher final drive rebuild cost tier. Parts are physically larger, planetary gear sets are more expensive, and pressure-test setups require more powerful bench equipment. Common on Cat 320/330/336, Komatsu PC200/300, Deere 200G/240G/350G class machines.
Dozer and wheel loader final drive rebuild — $3,500 to $8,500
Similar range to excavators. Dozer final drives take heavier shock load; wheel loader finals see high-speed rotation. Both benefit from bench pressure-testing after rebuild.
What Drives Final Drive Rebuild Cost Higher
- Contaminated case — a final that ran with metal debris in the oil damages every downstream component. Full inspection and cleaning adds hours.
- Piston motor damage — if the seal leaked and dry-ran the piston group, that adds a full piston motor rebuild ($800-$1,600) on top of the planetary and seal work.
- Case machining — if a mount boss or bearing bore is worn, sleeving adds machining time and parts.
- Rush service — construction and rental fleets often need turnaround under two weeks. Rush turn possible when the crew is stopped.
Final Drive Rebuild Cost Versus Exchange Unit
For common families where exchange units are available, exchange is often the honest answer when the machine is on a critical timeline. Exchange price runs comparable to rebuild plus a core credit for your unit. Rebuild wins when the timeline allows and the case is in good condition — you get a warrantied final with known history.
The Difference Between “Final Drive” And “Travel Motor”
Some customers ask about final drive rebuild cost when they actually mean travel motor rebuild. The distinction matters:
- Final drive = the whole assembly (travel motor + planetary gears + hub + brake). Rebuild covers all four sections.
- Travel motor = the hydraulic motor piston group only. Cheaper to rebuild alone ($800-$1,600) but only makes sense if the planetary, hub, and brake are still healthy.
We typically recommend a full final drive rebuild when the case is opened because debris from any failed section damages every other section over time.
Ship-In Final Drive Rebuild — Fleet Accounts Welcome
Rental fleets and out-of-state construction contractors ship final drives to Ames every week. Pull the final from the machine, drain the oil, cap the ports, strap to a hardwood pallet, ship LTL. Include your name, callback number, and machine make and model. Standard turn is two weeks from receipt.
Common Failure Modes That Change Final Drive Rebuild Cost
Most final drive rebuild cost jobs start with a customer describing one of a handful of predictable failure patterns:
- Oil leaking at the sprocket or hub — the cheapest final drive rebuild cost tier when caught early. Duo-cone seal and shaft seal replacement.
- Howling or grinding under load — planetary bearing wear. Mid-range cost — bearings, gears if pitted, seals.
- One track not driving — piston motor failure inside the final drive. Higher cost tier because motor rebuild is added.
- Brake will not hold on slope — brake pack contamination or spring pack fatigue. Mid-range cost.
- Metal chips on the drain plug — full teardown required regardless of what specifically failed, because debris that traveled damages everything downstream.
How Ames Hydraulics Quotes Final Drive Rebuild Cost
Every final drive rebuild cost estimate at Ames follows the same process. First: photograph the outside of the unit for record. Second: drain the case oil and inspect the drain sample for metal, water, and burn smell. Third: disassemble the planetary, hub, brake pack, and motor sections. Fourth: measure every wear surface against the service manual. Fifth: write the estimate. Nothing gets ordered until you approve the number.
Frequently Asked Questions About Final Drive Rebuild Cost
Why is final drive rebuild cost so much lower than a new final?
A new OEM final drive typically runs $8,000-$15,000+ depending on machine class. Rebuild cost is 30-50% of that because the case, mounting hardware, and heavy castings are reusable — only the wear parts (bearings, seals, gears, piston group) get replaced.
Is final drive rebuild cost worth it on an older machine?
For most machines under 10,000 hours where the case is not worn past service limit, yes. Above 10,000 hours we help you compare rebuild against exchange or used-final honestly.
How long does final drive rebuild take?
Two-week standard from receipt. Emergency and rental-fleet priority work turned faster. Some Kubota SVL planetary gear sets have longer parts lead time than standard.
Do you rebuild both sides of the machine at once?
Yes, and rental fleets and construction operations usually do. Matched-pair rebuilds run at the same time on the bench so tolerances land within a tight window between the two sides. Prevents one side wearing faster than the other after reinstall.
Do you warranty final drive rebuild work?
Yes. Written warranty on parts and workmanship. Terms print on the invoice.
