What Causes The Connecting Rod to Break and Fix It?

Motorcycle — Welcome back to the blog that contains about the motorcycle, Which we will discuss the piston rod. Starting from the piston rod function? What is the symptom of the damage? What is the effect of the damage? And how to fix it?

Understanding Connecting Rods

Connecting rod is a component that serves to connect the piston with the crankshaft, the piston rod works with up and down motion caused by the impulse of the piston and forwarded to the crutch. Because the impulse of the piston with the pressure changes, that is, when the piston moves to the Top Dead Point (TMA) the connecting rod will work heavier as it gets pressure from the piston. Conversely, as the piston moves to the Lower Dead Point (TMB), the connecting rods will work much lighter.

A simple example when a motorcycle engine is at 6,000 rpm, the connecting rod will receive a load of 2440 grams as it moves towards TMA. But when going to TMB connecting rods will receive a load of 1300 grams, because the work is very heavy then the piston rods need to be made with high quality mixed steel material and not easily bent or twisted.

The cause of the Correction Rod is Damaged

Oil Engine Substitution

Engine oil is very important for motorcycle engine performance, so it is required to change engine oil regularly every 2,000 km or 2 months (priority has been achieved first). If it exceeds the above limit, engine oil capacity will usually decrease and the most dangerous is the engine oil is depleted, this often happens on motorcycle type scooter and motorcycle that use fake oil.

Motorcycle Out of White Smoke

For a 4-stroke motorcycle whose exhaust emits white smoke with a pungent odor, it is most likely the piston is damaged or may come from a cylindrical valve that causes damage. If it is left in a long time it will spread to the connecting rod, then if the motorcycle issued white smoke should be quickly repaired.

Break through Flood

During the rainy season a lot of riders are desperate and think easy floods that are high below the knee, do not get me wrong things will make a lot of money is depleted. Why waste money? The cause of the water hammer that often makes crooked connecting rods. Water hammer often occurs on motorcycles with high compression ratio, this happens when the driver breaks through the flood and with the position of the gas grip is half full or the speed 55 km / h then just seconds down the gas grip position or speed, then pull the gas grip again. At the moment the gas position goes down it will be the sound of the colliding iron and the motorcycle will die totally due to the position of the crooked connecting rod. We recommend that when the flood crash never lower the speed or position of grip gas because this will allow the occurrence of water hammer.

Engine Oil Mixed with Foreign Substances

Here we take samples of water mixed with engine oil, the water in question can be water due to flood or rain water that enter into the machine through the engine respiratory tract. Does every motorcycle engine have a respiratory tract? Clearly yes, and usually the engine's respiratory tract will enter into the air filter. So if your motorcycle has an air filter with a very close distance to the ground, so be very careful bro.

Age of Motorcycles

In conclusion that motorcycles routinely change engine oil and never hit the flood or engine oil is not mixed with foreign substances it can be ascertained cause the connecting rod broken because of age wear.

Engine Modification

For the likers speed often modify the machine is mandatory, but the components used are part innate motorcycle manufacturer is not a special part that is intended for the competition. Yet every manufacturer limits the speed and quality of materials on each component of the built-in motorcycle.

The Connector Bar effect is Damaged

Piston bearings, pistons, cylinder comp become damaged.

For damaged connecting rods, it will usually create a rough engine noise with a tech, tek, tek sound in the center of the motorcycle engine.

Engine power becomes reduced or not have energy when used.

The connecting rod is left in the absence of a blind then it will spread to other related components.

Connecting Rod Bending effect

If the connecting rod is bent then the piston will lock to the comp cylinder and the motorcycle will be totally dead.

How to Fix Corrective Connecting Rod

There is only one way to fix a broken linking rod that is by replacing a new part, but when doing a replacement there are two options to replace a separate or assembled. If the replacement separately excess cheaper price because the component is assembled in lathe workshop without replacing crank shaft, but the shortcomings sometimes not balance and most unlucky not last long.

If replacing the assembled the price of a more expensive part can be 3 times the price of the connecting rod apart, but the excess is more balance and for part more durable.

OK bro, so long ago make this article and hopefully useful do not forget to spread to people. Keep driving safety first and do not be arrogant on the highway.
