The Takeuchi TB250 and Its Global Footprint
The Takeuchi TB250 is a 5-ton class compact excavator known for its smooth hydraulics, operator comfort, and reliability in tight job sites. Manufactured in Japan, the TB250 was introduced in the early 2010s and quickly gained popularity in North America, Europe, and Asia. However, many units were imported through unofficial channels—commonly referred to as “grey market” machines—which complicates parts sourcing due to regional differences in components and serial number tracking.
One of the most common issues with aging TB250s is final drive leakage, particularly from the floating seals. These seals are critical for keeping hydraulic oil in and contaminants out of the planetary gear housing and motor assembly.
Terminology Notes
In one case, both final drives on a TB250 began leaking at the floating seals. The OEM dealer quoted $744 per seal set, with two sets required—one for each side. This brought the parts cost alone to nearly $1,500, not including labor. For a machine still mechanically sound, this raised the question: repair, replace, or wait for used parts?
Alternative Sourcing and Repair Options
Owning a grey market Takeuchi TB250 doesn’t mean you’re out of options when final drives fail. With accurate identification and a willingness to explore aftermarket or used parts, operators can restore functionality without overspending. Whether you choose to repair or replace, understanding the drive’s specifications and sourcing channels is key to keeping your machine productive and profitable.

Terminology Notes
- Final Drive: The planetary gear and hydraulic motor assembly that powers each track.
- Floating Seal: A two-piece mechanical face seal used to prevent oil leakage in high-pressure, high-contamination environments.
- Grey Market Machine: Equipment imported outside of the manufacturer’s official distribution network, often lacking local support or parts compatibility.
- MAG-26V-P-310: A KYB-manufactured final drive model used in some TB250 variants.

Alternative Sourcing and Repair Options
- Aftermarket floating seals: Some suppliers offer compatible seal sets for under $100 per side. These are often identical in dimensions and materials to OEM parts but sold under generic or house brands.
- Complete final drive replacements: FDC-brand or other aftermarket drives compatible with the MAG-26V-P-310 can be sourced for under $3,000 per side, including the motor. These are sold outright with warranties and may offer better long-term value if the original drives are worn internally.
- Used final drives: Salvage yards or online marketplaces occasionally list low-hour drives from parted-out machines. Compatibility depends on bolt pattern, sprocket fitment, and hydraulic port orientation.
- Repair is viable if the internal gears and motor are in good condition and only the seals are compromised.
- Replacement is preferred if the drive shows signs of internal wear, excessive noise, or metal contamination in the oil.
- Labor costs matter: Replacing seals requires disassembly and careful reassembly with proper tools. If labor is outsourced, the cost may approach that of a new unit.
- Document your drive model: Look for tags or cast numbers like MAG-26V-P-310 to identify the exact unit.
- Cross-reference seal dimensions: Measure inner and outer diameters and thickness to match aftermarket options.
- Establish a parts supplier network: Contact independent final drive specialists who stock grey market-compatible components.
- Keep spare seals on hand: For machines in active use, having a backup set of floating seals can prevent downtime.
- Inspect for internal damage: If the drive is leaking, check for metal shavings or burnt oil—signs of deeper issues.
