Frequently Asked Questions

How does an excavator swing motor work on a Daewoo excavator?

On a Daewoo excavator, the hydraulic swing motor drives a planetary swing reduction gearbox, and that reduction rotates the upper house. Broken Tractor carries both complete hydraulic swing motor assemblies and planetary swing reductions, so you can rebuild the full swing system or replace only the failed component.

What swing motor fits a Daewoo S300LC-V excavator?

Broken Tractor offers swing motor SKU 401-00457B for the Daewoo S300LC-V. The same swing motor also fits the Daewoo S300LC-7A and the long-boom S300LL. Matching the part number on your current motor is the surest way to confirm fitment.

What swing parts are available for a Daewoo S220LC-V excavator?

For the Daewoo S220LC-V, we carry the swing motor under SKU 170303-00045 and the swing reduction under SKU 2404-1063. With both available, you can replace the motor, the reduction, or the complete swing drive. Note that the S225LC-V uses its own swing reduction, SKU 2404-1063I.

Which Daewoo excavator swing reductions does Broken Tractor carry?

We carry swing reductions for the Daewoo S130LC-V (SKU 2404-1066A), S140LC-V (SKU 404-00062), S170LC-V (SKU 404-00017C), DH220LC (SKU 2404-1051A), S220LC-III (SKU 2404-1059A), S220LC-V (SKU 2404-1063) and S225LC-V (SKU 2404-1063I). Each reduction is matched to a specific model. If you are unsure which one fits your machine, match the part number on your old unit or call the parts team at (800) 909-7060.

Should I replace the swing motor or the swing reduction on my Daewoo excavator?

Which part to replace depends on which component has failed. The hydraulic swing motor and the planetary swing reduction are separate assemblies on Daewoo excavators. Broken Tractor offers both, so you can replace only the worn component or both parts in a full swing system rebuild. Confirm your model and the existing part number before ordering.
