Doosan S55-V Final Drive (Travel Motor)

Description

The Doosan S55-V Final Drive is a complete hydraulic travel motor built to power the tracks of Doosan Solar S55-V mini excavators. If your S55-V is losing tracking power, travelling unevenly, or leaking gearbox oil, a replacement Doosan S55-V final drive can restore full travel speed and responsive steering control.

Doosan’s compact excavator range was previously sold under the Daewoo brand. This model is often listed as Solar S55-V or Daewoo Solar S55-V, and shares its final drive configuration with the base S55. It’s worth noting the closely related S55-VC variant uses a different final drive setup, so confirming your exact model helps ensure the right part is supplied. The final drive combines a hydraulic travel motor with a reduction gearbox, and is commonly fitted with a two-speed motor for higher torque under load with a faster range for repositioning across site.

Common signs you need a Doosan S55-V final drive replacement:

• Weak or uneven travel on one side
• Reduced tracking power
• Grinding or clicking noise during travel
• Hydraulic or gearbox oil leaks
• Excessive vibration when moving
• Difficulty shifting between travel speeds

These symptoms can also stem from hydraulic, undercarriage or control-system faults. It’s worth checking the wider travel system before replacing the final drive itself.

Confirming the Right Fit for Your Doosan S55-V

Because the S55-V shares a platform with the S55 but differs from the S55-VC variant, final drive specifications should always be confirmed rather than assumed. Send us your model, serial number, plus photos of the existing unit with its hydraulic connections, so Arena Hydraulic and Machinery can confirm the correct fitment before you order.

FAQ

Q: Does this final drive fit every Doosan S55-V excavator?

A: Not necessarily. The S55-V shares its final drive configuration with the base S55, but the closely related S55-VC variant uses a different setup. The machine serial number should be checked before ordering.

Q: Is this the same as a Daewoo Solar S55-V final drive?

A: Yes — Doosan acquired Daewoo’s construction equipment division, so this model is commonly listed under both names. It refers to the same machine platform.

Q: Will a standard S55 final drive fit my S55-V?

A: Often yes, since these two share the same final drive configuration — but this should always be confirmed with your serial number and photos rather than assumed.

Q: What information is needed to confirm compatibility?

A: Provide the complete model, serial number, identification plate and clear photos of the existing final drive, mounting points and hydraulic connections.
