The internal combustion engines used in Clark forklifts are made up of several individual elements. The synchronized work of all these elements allows the engine to work efficiently, generating enough power to drive the forklift from one place to another according to their material handling demands. Among all these elements, ones of the simplest but, at the same time, ones of the most important are gaskets. Clark forklift gaskets protect the engine; if they deteriorate, the engine would be exposed to harmful agents that will make it work worse. With this in mind, at Lift Parts Warehouse, we want to expand a little more on the importance of these elements and the considerations that must be taken when buying their replacements.

What is a Clark Forklift Gasket?

Clark forklift gaskets are specially designed to fill the space between two or more mating surfaces on the Clark lift trucks, generally to prevent leakage from or into the joined objects while under compression. Gaskets for Clark forklifts are made from various materials, depending on their applications. These gaskets are also available in multiple sizes, shapes, and thicknesses to suit different Clark lift truck models.

Clark forklift's engine has a wide range of fluids and gasses constantly moving through, each aiding or performing certain critical functions. As these fluids circulate, Clark forklift engine's gaskets work as seals to maintain pressure, hold fluids, and prevent debris and dust from entering the engine.

Several types of gaskets are used in various parts of these engines. Some are located inside, while others connect the engine to other components, like the intake manifold. In order to perform their job, Clark forklift gaskets are designed to withstand extreme temperatures, tolerate a wide variety of chemicals, and mold themselves to imperfections on the surfaces they are sealing.

The Most Important Gaskets in Your Clark Forklift

On a Clark forklift, there are many seals and gaskets involved. But among all gaskets, the most relevant are those directly related to the engine. Below we describe these important Clark forklift gaskets and their role.

  • Head Gaskets. These Clark forklift gaskets provide the seal between the engine block and cylinder head(s). Their purpose is to seal the combustion gasses within the cylinders and prevent coolant or engine oil from leaking into the cylinders.
  • Intake/Exhaust Manifold Gaskets. The Intake manifold is the part of an engine that supplies the fuel/air mixture to the cylinders. In contrast, an exhaust manifold collects the exhaust gasses from multiple cylinders. The intake manifold gasket helps to regulate the temperature inside the chamber and helps to prevent any air from escaping during the combustion process. It also ensures that the correct mixture of fuel and oxygen is used to keep the engine running at peak performance. The exhaust manifold gasket has a similar job but is located between the cylinder head and the exhaust manifold. A failing intake or exhaust manifold gasket can lead to bad performance and decrease fuel efficiency.
  • Valve Cover Gasket. Valve cover gaskets for Clark forklifts serve as mechanical seals between the valve cover and the engine cylinder head. The valve cover is a casing found on the top of the engine. It covers the engine's valves, protects the machinery from the elements, and prevents oil leaks.
  • Camshaft Gaskets. The camshaft gaskets for Clark forklifts help to prevent oil from seeping from the camshaft and keep dirt from getting into the Clark forklift engines. A faulty gasket can lead to internal leaks, causing damage to the engine and all mayhem to break loose.

  • Contaminated Engine Oil. If the engine oil in your Clark lift truck has a clear and bright color, it means that the engine is in good condition. If you notice that the engine oil becomes dull or dirty in a short time, it may mean that the oil filter is probably damaged or clogged, or something is wrong with one of the main Clark forklift gaskets of the engine.
  • Bad Engine Performance. If engine gaskets for Clark forklift deteriorate, it can lead to different problems that will affect Clark lift truck engine performance. For example, some oil might get into the cylinders, making it difficult for the air and fuel mixture to ignite. Another possible loss of pressure is if the gas compression process fails because of a blown gasket, this will cause the vehicle to lose much of its efficiency.
  • Increasing Engine Noises. When the main gaskets on Clark Forklifts fail, the engine gets exposed to contaminants or abrasive elements that eventually cause it to fail. When these failures are severe enough, strange sounds may be heard when the engine runs.
  • Low Coolant Level. If the gasket between the engine block and cylinder head fails, some coolant fluid can leak into the cylinders or escape outside the engine. If this continues, the coolant level will be lower each time. It is important to take care of this issue since the lack of coolant will trigger an increase in temperature, eventually accelerating the deterioration of the engine components.
  • White Smoke From Exhaust Pipe. A faulty head gasket most often results in large smelling white smoke coming from the exhaust. This is because some coolant passes into the cylinders and turns into steam during the combustion process. We must watch this failure closely; the lack of coolant will make heat dissipation worse and negatively affect the lift truck's water pump.
  • Engine Overheating. When the cylinder head gasket fails, it can cause the engine to overheat because both the lubricating oil and coolant will leak out. This can often be accompanied by a strong burning smell, as the high temperatures affect soft components such as seals, hoses, or belts.

How to Choose the Right Clark Forklift Gasket

There are a few things you need to think about when buying Clark forklift gasket replacements. In the market, you can find different types of Clark forklift gaskets, whether it is in shapes, sizes, and materials. You can also choose between OEM or aftermarket replacements, each with advantages and disadvantages.

The first thing we need to do is find the right gasket for our Clark forklift. We don't want to buy a new gasket that won't fit. So we need to make sure that the gasket matches the engine model of our forklift truck. To do this, we can look in the manual for our truck. There, we will find a list of corresponding parts. Once we have found the part number of our gaskets, we can start looking for a replacement.

The next step is to decide if you want to buy an OEM or aftermarket replacement gasket. OEM parts are made specifically for their corresponding forklift model, but they tend to be more expensive. On the other hand, aftermarket parts are a lot more affordable and usually compatible with multiple models, but you have to make sure that they meet the same engine specifications before you buy them.
