Mercedes Hex Bolt - Genuine Mercedes 910105008014

Product Information

An engine crankshaft main bearing cap bolt is a high-strength fastener that secures the main bearing caps to the engine block. These caps hold the crankshaft in place and keep the main bearings properly aligned, allowing smooth rotation under heavy loads. The bolts must maintain precise torque and clamping force to prevent movement of the crankshaft, ensuring durability and performance.

• Knocking or deep engine noises, if the crankshaft shifts due to loose or weakened bolts.
• Loss of oil pressure, caused by bearing misalignment or damage.
• Severe engine damage or seizure, if a bolt breaks or stretches, allowing the crankshaft to move out of position.

About Genuine Mercedes

The original parts used by Mercedes Benz to build your car are available as replacement parts under the “Genuine Mercedes Benz” brand. Manufactured under the direction of Mercedes Benz, expect excellent quality and a premium price since these parts are exclusively available through the Mercedes Benz Dealership network.

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz. No cause for concern, as Mercedes-Benz designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
