Positioned at the back of the engine block where the crankshaft connects to the transmission, this seal is the final barrier for the engine's lubrication system. It is engineered from high-grade PTFE (Teflon) to provide a low-friction, high-durability seal capable of withstanding the high torque and vibration levels characteristic of BMW’s diesel powerplants.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eOn the N47 and M47 platforms, the rear main seal is a labor-intensive but critical component. Because it is located behind the flywheel (or drive plate), accessing it requires removing the entire transmission. Common symptoms of a leak include \u003cb data-path-to-node=\"2\" data-index-in-node=\"244\"\u003eoil dripping from the bottom of the bell housing\u003c\/b\u003e or a contaminated clutch in manual transmission models. Due to the high labor cost associated with this repair, it is strongly recommended to replace this seal whenever the transmission is removed for other work, such as a clutch replacement or timing chain service (especially on the N47 engine, where the chain is located at the rear).\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003e\u003cb data-path-to-node=\"3\" data-index-in-node=\"0\"\u003eVehicle Compatibility:\u003c\/b\u003e This seal is designed for the \u003cb data-path-to-node=\"3\" data-index-in-node=\"53\"\u003eM47 and N47 2.0L 4-Cylinder Diesel\u003c\/b\u003e engines:\u003c\/p\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,0,0\"\u003e\u003cb data-path-to-node=\"4,0,0\" data-index-in-node=\"0\"\u003e3 Series (F30):\u003c\/b\u003e 1998–2015 (318d, 320d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,1,0\"\u003e\u003cb data-path-to-node=\"4,1,0\" data-index-in-node=\"0\"\u003e1 Series (F20):\u003c\/b\u003e 2004–2015 (118d, 120d, 123d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,2,0\"\u003e\u003cb data-path-to-node=\"4,2,0\" data-index-in-node=\"0\"\u003e5 Series (F10):\u003c\/b\u003e 2000–2014 (520d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,3,0\"\u003e\u003cb data-path-to-node=\"4,3,0\" data-index-in-node=\"0\"\u003eX3 (F25):\u003c\/b\u003e 2004–2014 (18d, 20d, 23d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eEngine Application:\u003c\/b\u003e M47 \/ M47N \/ N47 \/ N47D20\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eSeal Type:\u003c\/b\u003e PTFE (Polytetrafluoroethylene)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003e\u003cb data-path-to-node=\"6,3,0\" data-index-in-node=\"0\"\u003ePosition:\u003c\/b\u003e Engine Rear (Crankshaft to Transmission)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BMW","offers":[{"title":"Default Title","offer_id":48198307348719,"sku":"11147797490","price":395.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/7183\/5631\/files\/2015-F30-328d-Diesel-Rear-Main-Seal_caf5b064-7b9a-4d66-b594-5c8315637871.png?v=1774499622","url":"https:\/\/myty.co.za\/products\/crankshaft-rear-main-seal-bmw-n47-n57-b57-diesel-engines","provider":"MYTY Auto Parts","version":"1.0","type":"link"}
