Some Of The Causes Of Jeep Rocker Arms Failure

By Amy Kelly


Over the years, there has been the optimization of the rocker arm in its design and material so that it could perform better. The reasons for the optimization of this product are toughness, durability, resistance to wear, the cost of the material and strength. However, this has not succeeded and here is what you need to know about Jeep rocker arms failure.

One of the most dominant failures of the mechanism is the having a fracture occurring at the hole of the rocker arm. This is mainly as a result of fatigue from multiple origins. When this happens, there is the spheronization of the cementite that is found in the pearlite that results to having lower fatigue strength when the hardness of the product used in making the arm reduces.

Most of the times, we take good care of our engine to protect it from any damages or fracture. But no matter how hard we try it might get a fracture, and if it occurs in the neck of the arm, then it is bound to bring failure. The fracture will prevent the rocker arm from running, and this will lead to failure.

When you are loading your machine, you should be very careful to look the limits which the machine can take. When you overload it, this may lead the machine to bend and cause failures. When you do not consider the striation spacing and the factor of the range of stress the load will bend leading to failures of the machine.

If you do not maintain and check your engine regularly, the arm pads of rockers may experience tear and wear. This is caused by the corrosion of menthol, a chemical reaction. When the silicon nitrates, pads for LPG taxi wear out there is excess calcium and phosphorus which comes into conduct with oil lubricated surfaces. This produces zinc dialkyl dithiophosphate which causes the menthol chemical reaction.

The other thing that you should do is to avoid carbon gas building up at the valve stem. This gas can cause wear to the inner part of the diameter putting into consideration that this part is in line with the rocker arm-centric line. Ensure that there is a way provided for the gas to exit.

The other element that can cause failure is friction. Having continuous interaction with the valve stem and pushrod will result in friction. This mainly happens due to the cheap formation, and it is another cause for the device to fail.

The rocker arm is an essential part of an engine, and when it fails, it makes the engine useless. The replacement and repair are costly, and that is the reason that the designers are trying to come up with a device that will not fail. The engineers are working to make a lightweight product that is strong enough so that the failure can be reduced.
