Tractors, like other vehicles, can experience various engine failures due to wear, poor maintenance, or mechanical issues.
Do you know what the most common ones are for each engine part? Let us tell you:
Block
Breakage or perforation of the engine block due to a connecting rod breaking. A broken connecting rod allows the piston connected to it to exit its housing during the explosion and perforate the block after colliding with the crankshaft.
Cylinder Head
Deformation due to engine overheating, which damages the seal and causes loss of compression in the cylinders or causes oil or coolant to mix.
Cylinder Head End
Breakage or crack that allows cylinder pressure to escape to the outside, to the coolant circuit, or to the oil circuit.
Rocker Cover
Oil leakage through the cover seal. This is not a very serious fault and is usually easy to fix.
Camshaft
Wear of the camshaft due to lack of lubrication produces imperfect valve openings and closings, resulting in power loss and can seriously damage the engine. In extreme cases, this can lead to the seizure of the camshaft rotation, necessitating a very costly repair.
Intake and Exhaust Valves
Valve floating. This occurs when the timing of the valve opening and closing is lost, and one of them remains open when the piston is closing at the end of its stroke. This results in a piston-valve collision that breaks or bends the valve and can perforate the piston or the cylinder head.
Cylinders
Engine seizure due to lack of lubrication and overheating of the cylinders. Friction between the piston and cylinder without lubrication causes heat expansion and locks the pistons' movement.
Pistons
Loss of compression due to piston ovality. Over time, in very worn engines, pistons may adopt an oval shape due to erosion of two of their support walls in the cylinder, and this deformation allows compression to escape during explosions, resulting in power loss.
Rings: Compression and Oil Scraper
Damage from foreign objects that scratch the cylinders can cause compression loss and oil burning. This occurs when air or fuel filters do not function properly, allowing sand or other particles to enter the combustion chamber.
Oil Pan
Breakage due to impact can cause the loss of engine oil and can lead to an even more serious fault. If this is not detected in time then the engine continues to operate without proper oil pressure.
Pin
Premature wear of the pin due to lack of lubrication, causing vibrations and noises during engine operation. In severe cases, if not addressed, it can lead to its breakage.
Connecting Rod
Breakage of the connecting rod bushing. This fault is caused by lack of lubrication or overexertion. The part itself is not expensive, but the labor for its replacement, due to the complexity of the disassembly, greatly increases the total cost.
Crankshaft
Breakage due to material fatigue or hydrolock (entry of water mixed with fuel that fills the cylinder and, being unable to burn, abruptly stops the piston's ascent).
Flywheel
Noises and vibrations due to wear that can affect the clutch. They occur due to the accumulation of stresses or aggressive driving.
Turbocharger
Turbo breakdown due to lack of lubrication of the shaft bearings. This can occur due to failures in oil pressure or by frequently turning off the engine without letting it idle for a few seconds after high engine effort. Lack of oil or its burning inside the turbo affects the bearings, which over time seize up and damage the rotation of the compression and exhaust turbines.
