What causes insufficient compression and leaking valves in Kubota D1703-M-E?
If the Kubota Engine is experiencing insufficient compression due to leaking valves, it may be caused by a bad valve or excessive wear of rings, pistons, and liners. Replace with new parts and grind the valves.
Why does Kubota Engine revolution suddenly decrease or increase?
If the Kubota Engine revolution suddenly decreases or increases, check the adjustments, injection timing, and the fuel system.
What to do if Kubota D1703-M-E makes unusual sound?
If the Kubota Engine suddenly makes an unusual sound, carefully inspect all moving parts.
What causes moving parts to overheat in Kubota Engine?
If the moving parts of your Kubota Engine are overheated due to a shortage of lubricating oil or improper lubrication: * Check the amount of engine oil using the oil level gauge. * Inspect the lubricating oil system. * Replace the oil filter cartridge every two oil changes. * Ensure the engine bearing clearances are within factory specifications.
Why does the exhaust of my Kubota D1703-M-E suddenly turn dark?
If your Kubota Engine exhaust suddenly turns dark, inspect the fuel injection system, especially the fuel injection nozzle.
