To Next PageTo Next PageWhy does my Doosan 7/26E Compressor engine not start?
Several factors can prevent your Doosan Compressor engine from starting: a discharged battery, bad cable connections, starter or starter switch failure, or a safety relay failure. Refer to Col4 for repair and diagnostic procedures.
What causes insufficient air intake volume in my Doosan 7/26E Compressor?
Insufficient air intake volume in your Doosan Compressor can be attributed to a clogged air cleaner or restricted air flow.
What causes battery over discharge in my Doosan 7/26E?
Battery over discharge in your Doosan Compressor can be caused by low electrolyte level (crack in battery body) or natural consumption. Check for a crack in the battery body.
What causes oil leakage in my Doosan 7/26E?
Oil leakage in your Doosan Compressor may stem from a damaged seal or turbocharger seal, loose joints or gaskets, or improper installation of the filter and piping.
What causes my Doosan 7/26E to have excessive white smoke?
Excessive white smoke from your Doosan Compressor can be caused by water mixing in the fuel, low compression pressure, incorrect injection timing, low coolant temperature, or a faulty turbocharger.
What causes low engine output in Doosan 7/26E Compressor?
Low engine output in your Doosan Compressor can stem from several issues: incorrect injection pump adjustment (incorrect injection timing), injection nozzle malfunction (incorrect injection pressure), insufficient fuel supply to the injection pump (lack of fuel in tank), air in injection pump, a clogged fuel filter, overflow valve malfunction, or governor malfunction (incorrect engine control adjustment) or deteriorated governor spring. Check for incorrect injection timing, incorrect injection pressure, and lack of fuel in tank.
What causes unstable engine running in my Doosan 7/26E?
Unstable engine running in your Doosan Compressor can result from unstable low idling (possibly due to a crack in the injection pipe), injection nozzle failure, engine stop solenoid return failure, or uneven compression pressure between cylinders. Check for a crack in the injection pipe.
Why is my Doosan Compressor engine burning oil?
If your Doosan Compressor engine is burning oil, it could be due to faulty piston rings or damaged cylinder bores, or a faulty valve stem seal.
What causes excessive fuel consumption in my Doosan 7/26E?
Excessive fuel consumption in your Doosan Compressor can be caused by fuel leakage due to damaged seals, improper component installation or tightening, or excessive injection volume due to a defective injection pump. Check for damaged seals.
What causes my Doosan 7/26E Compressor engine to overheat?
Engine overheating in your Doosan Compressor may be due to a cooling system defect, such as insufficient coolant volume, fan belt slippage, thermostat malfunction, radiator filler cap malfunction, a fouled cooling system interior, or a clogged radiator. Check for insufficient coolant volume.
