Kubota RTV500 Common Problems This Manual Covers
Engine overheating
An RTV500 worked hard in hot weather can run over temperature from a clogged radiator, a weak water pump or low coolant. The Engine Servicing section covers troubleshooting and oil pressure checks to find the cause.
Manual Section: Engine Servicing p. 99Weak or no drive from the HST
Loss of drive, creeping in neutral or sluggish travel usually points to the hydrostatic transmission or its linkage. The Transaxle Servicing section covers HST troubleshooting, specifications and assembly.
Manual Section: Transaxle Servicing p. 168Hard starting or rough running
Starting trouble and stumbling under load can come from the electronic control fuel injection or the engine body itself. The Engine Servicing section includes troubleshooting for both the engine body and the fuel injection system.
Manual Section: Engine Servicing p. 99Spongy or weak brakes
A soft pedal or long stopping distance often means worn pads, low fluid or air in the lines. The Brakes Servicing section covers bleeding, the 3.94 mm pad wear limit and pedal free travel adjustment.
Manual Section: Brakes Servicing p. 218Dead battery or no charge
A battery that keeps going flat points to the charging system, a faulty alternator or the IC regulator. The Electrical System Servicing section covers charging troubleshooting and component testing.
Manual Section: Electrical System Servicing p. 302Loose or wandering steering
Play at the wheel and vague tracking usually mean worn steering linkage or loose fasteners. The Steering Servicing section covers troubleshooting, tightening torques and disassembly.
Manual Section: Steering Servicing p. 274Frequently Asked Questions
