This Genuine Land Rover crankshaft rear oil seal for the 300Tdi engine is the correct replacement for the seal that lives at the rearmost end of the crankshaft, where it exits the engine block and interfaces with the flywheel housing. Its job is to prevent engine oil from migrating rearward past the crankshaft journal and into the bell housing. When this seal hardens, cracks, or wears, the resulting leak can coat the flywheel, contaminate the clutch disc on manual transmission applications, and leave a telltale oil film on the underside of the engine and transmission area.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe 300Tdi is a 2.5-liter (152.5 cubic inch) four-cylinder turbocharged diesel engine that powered the Defender, Discovery I, and Range Rover Classic through much of the 1990s. It is a beloved engine with a strong following, and keeping one leak-free means sourcing the right components from the right source. This Genuine Land Rover seal is built to the original factory specification, ensuring correct dimensions, proper lip material, and the correct interference fit with the crankshaft journal. Proper installation requires a clean journal surface and a seal driver or suitable sleeve to press the seal squarely into its housing without distorting the lip. Many experienced technicians recommend allowing the seal to sit overnight after installation so the lip can fully conform to the crankshaft surface before the engine is started.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis listing is for one seal. The rear main seal housing gasket (ERR6811) is a separate item and is not included. If you are replacing this seal as part of a full rear crankshaft reseal, sourcing the housing gasket at the same time is strongly recommended so the job only needs to be done once.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eFits:\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eDefender (from VIN WA138480 onward) 2.5-liter 300Tdi Diesel\u003cbr\u003eDiscovery I L318 (1994 to 1998) 2.5-liter 300Tdi Diesel\u003cbr\u003eRange Rover Classic (1992 to 1994) 2.5-liter 300Tdi Diesel\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003ePart Number: LUF100430GEN\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eFree shipping to the lower 48!\u003cbr\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSupersessions ERR6818, ERR4179\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eFAQ\u003c\/strong\u003e\u003cbr\u003eDoes this seal fit all Defender body styles including the 90, 110, and 130?\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eYes. The 300Tdi engine is shared across all Defender body styles produced from VIN WA138480 onward, and this seal fits the same engine in every configuration. The rear crankshaft seal is an engine component and is not affected by wheelbase or body style.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eIs the rear main seal housing gasket included with this seal?\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eNo. This listing is for the crankshaft rear oil seal only. The rear main seal housing gasket, sold separately under part number ERR6811, is a flat gasket that seals the housing to the engine block. If you are resealing the rear of the engine, replacing both at the same time is strongly recommended to avoid having to revisit the job.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eHow do I know if my crankshaft rear oil seal needs replacing?\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe most common sign is an oil leak at the rear of the engine, typically visible as an oily film on the bell housing, flywheel, or in the area between the engine and gearbox. On manual transmission Rovers, a contaminated clutch disc is another indicator. If you are already removing the gearbox for a clutch job, inspecting and replacing this seal at the same time is considered best practice regardless of its apparent condition.\u003c\/p\u003e","brand":"ALLMAKES \/ BRITPART","offers":[{"title":"Default Title","offer_id":54042385187029,"sku":"LUF100430GEN","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2178\/4267\/files\/watermarked-IMG_7922_1.jpg?v=1781533082","url":"https:\/\/lucky8llc.com\/products\/luf100430-genuine-crankshaft-rear-oil-seal-fits-discovery-i-defender-rrc","provider":"Lucky8 Off Road ","version":"1.0","type":"link"}
