Kubota V1505-T-E4B Common Problems This Manual Covers
Hard starting or poor running
Hard cold starts, low power, or rough running on the V1505-T-E4B call for a structured diagnosis of compression, fuel, and glow circuits. The Servicing section opens with a troubleshooting chart, then the servicing specifications to check against.
Manual Section: Servicing p. 61Low oil pressure
Low oil pressure at idle or rated speed threatens the engine and needs checking against the factory figures. The Servicing section covers the lubricating system checks and the oil pressure specifications for this engine.
Manual Section: Servicing p. 61DPF or after treatment faults
Poor regeneration, warning signals, or emissions faults involve the after treatment hardware rather than the base engine. The Mechanism section explains the diesel oxidation catalyst, diesel particulate filter, and the temperature and differential pressure sensors.
Manual Section: Mechanism p. 55Overheating
Running hot points to the cooling system, thermostat, or coolant level, all of which need checking before further damage. The Servicing section covers cooling system checks and the related servicing specifications.
Manual Section: Servicing p. 61Loose fan belt or weak charging
A slack fan belt causes a squeal, a weak charge, and overheating together. The General section covers the maintenance check list and the fan belt deflection specification to set the belt correctly.
Manual Section: General p. 14Valve clearance drift
Clearances that fall out of spec cause noise, hard starting, and lost power over time. The Servicing section gives the cold valve clearance limits and the checking and adjusting procedure.
