Product Description
Main Engine Bearing Set, 0.010" Over, Complete Set Per Engine (17465.19) by Omix-Ada®. The only thing between your main bearings and crankshaft is a thin film of pressurized oil. If dirt or metal particles enter this small space, the crankshaft and bearings can become scored. Enough wear and scoring and soon the oil clearance is too great to fill with the oil pressure developed by the oil pump. The result is metal-to-metal contact, which can cause expensive engine damage like a ruined crankshaft, spun bearings or worse. Replace your worn main bearings before expensive damage can occur with these OEM spec quality units from the Jeep experts at Omix-Ada.

In fact, that thin film of oil (typically just 0.0025"-0.003") mentioned above can disappear for other reasons other than foreign particles. Bearings can wear with use, they can be starved of oil if there is a pump or clogged oil passage problem, and they can also become fatigued due to detonation or engine lugging. The crankshaft thrust bearing can fail due to excessive torque converter pressure or from riding the clutch pedal, resulting in excessive crankshaft end-play.
Most plain bearings are constructed with a steel backing that provides support, with overlays of copper and/or lead alloy, and final surface coating of Babbitt material, to provide a soft surface if shaft contact is made and to collect contaminants that would otherwise damage the crankshaft. Symptoms of main bearing failure include knocking, particularly at engine startup, and low oil pressure. Most oil pressure lights don't illuminate until pressure is very low, so even if you don't see a light but hear a lot of clattering and knocking, chances are you have low oil pressure.
Whatever the reason for failure, when you're ready to replace your main bearings look to Omix-Ada for the quality, OEM spec main bearings that will maintain oil pressure for optimal engine performance and long engine life. Bearing construction is according to OEM design, so you can be assured they'll work perfectly with OEM spec oil clearance. And if your crankshaft requires grinding undersize to restore the finish, Omix-Ada offers bearing sets in all popular oversizes, so you can always set the oil clearance to factory specifications.
