400915-00269A Engine Oil Pump for Doosan D34 3.4L Diesel Engine

   The 400915-00269A is a high-flow gear-driven oil pump engineered to meet the strict lubrication requirements of the Doosan D34 platform. This engine is commonly found in Tier 4 Final Bobcat and Doosan machinery. Because the D34 utilizes a turbocharger, the oil pump must not only lubricate the block but also provide a steady stream of oil to cool the turbo bearings. This pump is manufactured to precision tolerances to maintain peak oil pressure even at low idle speeds.

Q&A Section

Q1: What are the symptoms of a failing 400915-00269A oil pump?

A: Common indicators include a flickering oil pressure warning light, increased engine noise (ticking or knocking), and higher-than-normal engine temperatures. If you see the "Low Oil Pressure" code on your Bobcat/Doosan monitor, stop the engine immediately to prevent a total seizure.

Q2: Should I replace the oil pump pickup tube gasket at the same time?

A: Yes. A leaking or brittle gasket at the pickup tube can allow air to be sucked into the pump, leading to oil aeration and a loss of pressure. Always use new seals and gaskets during installation.

Q3: Can a clogged oil cooler affect the performance of the new pump?

A: Definitely. If you are replacing the oil pump due to a previous engine failure, it is mandatory to flush or replace the oil cooler. Metal debris from the old pump or bearings can lodge in the cooler and migrate into your new 400915-00269A, destroying it instantly.
