Frequently Asked Questions
What swing bearing fits a Doosan DX140LC-3?
The Doosan DX140LC-3 uses swing bearing SKU 140109-00016A. The same bearing also fits the DX140LC-5, DX140LCR-3, DX140LCR-5, DX160LC-3 and DX160LC-5. Match the part number on your machine before ordering to confirm fitment.
Is the swing bearing the same on Doosan -3 and -5 series excavators?
Some Doosan swing bearings cover both generations, but not all of them. For example, SKU 140109-00017B fits both the DX180LC-3 and DX180LC-5, and SKU 140109-00003A fits both the DX530LC-3 and DX530LC-5. Other models use their own bearing, so always check the fitment list for your exact model and suffix.
What swing bearing fits a Doosan DX300LC?
The Doosan DX300LC, DX300LCA and DX3000LL use swing bearing SKU 109-00181A. The DX300LC-3 uses a different bearing, SKU 140109-00001B, so confirm your model suffix before ordering.
What swing bearing fits a Doosan DX340LC or DX350LC?
Broken Tractor carries swing bearing SKU K1006604, which fits the Doosan DX340LC, DX340LCA, DX340LC-3, DX340LC-5, DX350LC, DX350LC-3 and DX330LC-5. For the larger DX480LC, DX490LC-3, DX500LC, DX530LC-3 and DX530LC-5, the correct bearing is SKU 140109-00003A.
Does the Doosan DX140W-3 use the same swing bearing as the DX140LC?
No, the wheeled DX140W-3 uses a dedicated swing bearing that is specific to its wheeled undercarriage configuration. Do not substitute the DX140LC bearing. To confirm the right part for your machine, call our parts team at (800) 909-7060.
