Overflow tank for Doosan
This overflow tank is a direct replacement part developed for Doosan. It is built to OEM dimensional specification, so it installs in the original position without any modification to the surrounding assembly.
Part number / cross reference
OEM and interchange reference: DX350-9 | DX300 | DX520LC-9C | DX380-9C | DX480-9C
Use the number from your parts book to confirm interchangeability. If your number is not listed, send it to us — we cross-check against the parts manual and confirm in writing before you pay, because a wrong part costs far more in freight and downtime than the part itself.
Why this part fails — and what we do differently
Inside an engine, tolerance is everything. This overflow tank is machined to OEM dimensional specification, with surface finish and concentricity checked piece by piece, because a small deviation here turns into oil consumption or premature bearing wear on Doosan machines. Material and heat-treatment certificates can be supplied on request.
Ordering, packing and warranty
Single pieces ship for urgent breakdowns; consolidated container or air freight is available for stock orders. Each part is packed individually in a carton with the part number labelled, and we send photographs of the actual goods plus a measurement report before shipment. Warranty: 6–12 months against manufacturing defect under normal operating conditions.
