WESPC U5MB0018D Bearing Replacement Fits Per-kins 1104 1106 Engines Main Bearing Set

WESPC U5MB0018D is a main bearing kit designed for Perkins 1104 and 1106 series diesel engines, perfectly compatible with common models such as 1104D-44T and 1106A-E66TAG1.

During engine operation, the main bearings bear the critical responsibility of supporting the crankshaft. The U5MB0018D ensures stable crankshaft rotation, precisely maintains clearances between components, and reduces friction losses. Through reliable support and consistent performance, it guarantees smooth power delivery from the engine. Compatible with the 1104 and 1106 series engines, these units are extensively deployed in 100-250kVA generator sets, delivering continuous power across diverse settings. Within construction machinery such as compact excavators and skid steer loaders, they enable agile operation. In agriculture, tractors and seed drills rely on these engines to perform tillage, sowing, and other farming tasks.
​
The U5MB0018D employs advanced sintered tri-metal construction, featuring a copper/lead-tin base alloy with nickel barrier and Babbitt alloy top layers. Compared to aluminium or other copper/lead alloys, this material delivers superior load-bearing capacity, extending service life under normal conditions while significantly enhancing fatigue resistance in extreme operating conditions. This effectively reduces engine downtime risks caused by bearing failure. Its precision manufacturing process ensures strict dimensional tolerance control, enabling exact fitment with engine crankshafts and cylinder blocks. Installation is straightforward, requiring no complex adjustments prior to operational deployment.
