Kubota Main Bearing Con Rod Bearing Thrust Washer Set WG3800

This engine bearing set comprises main bearings, connecting rod bearings, and thrust washers engineered for the Kubota WG3800 spark-ignition industrial engine series. The WG3800 is a 3.769-liter inline four-cylinder engine with a 100 mm bore and 120 mm stroke, derived from the V3800 diesel platform. The set restores crankshaft journal clearances to factory specifications during overhaul or rebuild procedures. Main bearings are available in standard and undersize dimensions (0.25 mm, 0.50 mm, 0.75 mm) to accommodate crankshaft regrinding. Connecting rod bearings match the 53 mm journal diameter. Thrust washers control crankshaft end-play within specified limits. Components are constructed from aluminum alloy or tri-metal bearing material with steel backing for high-load durability in continuous industrial operation. This kit services engines used in forklifts, generators, and stationary power units including Clark S-Series, Doosan, and Bobcat equipment.
