Toyota 9031146001 — Front Crankshaft Oil Seal
Overview
Front crankshaft oil seal Toyota 9031146001 seals the front snout of the crankshaft inside the oil pump housing and engine timing cover. The shaft seal prevents engine oil leaks along the rotating journal into the engine bay. Technical specifications include an inner diameter of 46 mm, outer diameter of 58 mm, and a width of 7 mm. Constructed from heat-resistant fluororubber (FKM) featuring an integrated dust lip and a garter spring made of carbon steel. The elastomer withstands operating temperatures from -40 °C to +180 °C while resisting hot engine oil degradation. Precision lip geometry reduces friction against the rotating steel journal surface. OEM reference number is Toyota 9031146001. Alternative cross-reference numbers include Musashi T1311, Payen NA5177, and Corteco 19027864B.
This component fits Toyota Land Cruiser 80, Land Cruiser 100, Crown, Mark II, Chaser, and Cresta models fitted with 2.0, 2.5, and 4.5 litre petrol and diesel engines manufactured between 1990 and 2007. Seal failure occurs due to hardening of the sealing lip, thermal degradation, material fatigue, or shaft wear grooves. Typical symptoms of failure include oil contamination on the crankshaft pulley, drops beneath the front timing cover, and reduced engine oil levels. Replacement of the front oil seal is required during routine timing belt servicing, crank pulley removal, or full engine overhaul to restore proper crankcase fluid containment.
