142-5868 is the OEM rear crankshaft oil seal exclusively for CAT 3412 large-bore V12 diesel engine. It is mounted inside the engine flywheel housing at the crankshaft tail end, responsible for blocking engine lubricating oil from leaking into the flywheel and clutch housing.
Widely used on CAT 3412 marine propulsion engines, large stationary generator sets and heavy industrial power units. A failed rear crank seal will cause heavy oil dripping into the bell housing, contaminate clutch friction plates, reduce engine oil volume and trigger insufficient lubrication risks. It is a mandatory replacement component during engine major overhaul, flywheel removal and transmission disassembly.
We supply parts for Kubota, Cum mins, CAT, Perkins, Yanmar, Isuzu, Komatsu, Mitsubishi, Hino, Nissan, Vo lvo, Deutz, Doosan, Daewoo, John Dee re, Scania, Hyundai, JCB etc.
