Mercedes injector puller

Types of Mercedes Injector Puller

If one is working on a Mercedes-Benz diesel engine, a Mercedes injector puller is a must-have tool. When shopping for this tool, there are various types to expect. The Mercedes diesel injector puller comes in different sizes and designs to accommodate various injector sizes and engine configurations. Below are the types of injector pullers.

• Slide Hammer Puller

  This tool uses a slide hammer mechanism to extract stuck or seized injectors gently. It consists of a slide hammer and a pulling attachment that connects to the injector. As the slide hammer is pulled back and thrusts forward, it creates a force that dislodges the injector from its seating. The process is repeated until the injector loosens and comes out. This tool is ideal for Mercedes-Benz models where the diesel injectors are known to get stuck, especially when removed after a long time.

• Forked Puller

  A forked puller has a forked end that fits around the injector body. Sometimes, the forked puller also has a hook or a claw that engages with the injector. The mechanic uses a ratchet or a wrench to turn the central bolt, which pulls the forked end upward. The upward force gradually loosens the bond between the injector and the cylinder head until the injector comes out. The forked puller is an ideal choice when removing short or compact injectors that have minimal space around them.

• Two or Three-legged Puller

  This tool has two or three legs that attach to the injector body or surrounding area. Once the legs are attached, a central bolt is turned. The mechanism draws the legs closer together, pulling the injector upward. The two-legged puller is ideal for deep-seated injectors, while the three-legged puller is used when the injector is broad and has a large diameter.

• Mercedes-Benz Special Injector Puller Tool Kit

  Some mechanics opt to buy a Mercedes-Benz injector puller tool kit. This is because the tool kit is designed specifically for removing and installing fuel injectors on Mercedes-Benz vehicles. The tool kit incorporates slide hammer pullers, forked pullers, two-legged pullers, and other specialized tools such as injector installation guides, and cleaning brushes all packed in one case. The tools are of different sizes to accommodate various diesel injector sizes. The injector puller tool kit saves time since all the needed tools are in one case. One can also work on other vehicle models by using the tools in the kit if they are compatible.

How to choose Mercedes injector puller

Choosing a Mercedes injector puller can be a daunting task, but it doesn't have to be. Here are a few things to note:

• Understand the task at hand:

  Before embarking on the process of choosing an injector puller, it is important to understand what an injector puller does. An injector puller is a tool designed to remove fuel injectors from an engine. Over time, fuel injectors can become stuck or seized in their respective engine cylinder head ports. When this happens, the injectors can be difficult to remove using traditional methods. The injector puller comes in handy in this scenario by forcing the injectors out of the cylinder head with controlled and precise pulling and lifting forces. The injector puller ensures the fuel injectors can be removed without causing damage to the injectors or the surrounding engine components.

• Know the different types of injector pullers:

  There are several types of injector pullers, each suited for a different situation. Knowing the different types and their applications will make the selection process easier.

• Consider the engine type:

  Different engines have different injector designs and layouts. When choosing a Mercedes diesel injector puller, the engine type is an important consideration. For example, the Mercedes Benz OM611 and OM646 engines have their injectors located under the cylinder head. This means that the injectors in these engines require a more complex and longer procedure for removal. The injector puller for Mercedes diesel engines should be able to remove the injectors from the cylinder head without causing any damage.

• Check the material:

  Like any other tool, the injector puller will be subjected to wear and tear over time. To avoid the situation where the tool becomes ineffective after a few uses, it is advisable to choose a puller made from high-quality materials. The most common materials used to make injector pullers are steel and aluminum. Steel pullers are more durable and can withstand more force. However, they are heavier than aluminum pullers and may not be suitable for all injector removal situations.

How to diy and replace the mercedes injector puller

It is essential to know that removing and installing fuel injectors requires some level of mechanical expertise. If, by any chance, the fuel injectors are damaged, they may cause the engine to run poorly or emit excessive pollutants. Therefore, if the damage is beyond repair, a replacement may be necessary.
