Audi VW Crankshaft Main Bearing Set - Glyco 078198491

Product Information

An engine crankshaft main bearing is a crucial component that supports the crankshaft in the engine block and allows it to rotate smoothly. These bearings are typically metal shells lined with a soft, durable material (like babbitt or a copper-lead alloy) and sit between the crankshaft journals and the engine block, and helps maintain proper oil clearance for lubrication.

• Knocking or Thumping Noise from Engine (Rod Knock or Main Knock): Often heard at low RPM or under load; a classic “engine knock” indicates excessive bearing clearance.
• Low Oil Pressure: Worn bearings increase oil clearance, causing a drop in oil pressure readings.
• Metal Shavings in Oil: Bearing material can wear off and contaminate engine oil.

About Glyco

Glyco is part of Federal Mogul and has been a leading manufacturer of bearings and bushings for over 30 years. Glyco offers over 2,500 different varieties of bearings, including Main Bearings, Connecting Rod Bearings, Intermediate Shaft Bearings, Wrist Pin Bushings and Piston Pin Bushings. These bearings can be found in more than 10,000 different engine applications.

Glyco creates bearings that have several layers of self-lubricating material, which means that they don't need to be lubricated at all after the initial installation. This means the bearings will last longer without maintenance than regular brands. Modern day engines are designed to lower CO2 emissions while also being more powerful and utilizing less gas. Traditional bearings may wear down under the extreme pressure and temperature. Glyco's lightweight bearings and bushings are designed to perform well under these conditions.
