{"product_id":"oil-pump-drive-chain-kit-in-uprated","title":"Oil Pump Drive Chain Kit in Uprated","description":"\u003cp\u003eA timing chain component: behind the same cover as the timing chain, so it is either done now or it is the same labour again in two years.\u003c\/p\u003e\u003cp\u003eWe are an independent parts supplier. We are not BMW AG or MINI, we are not appointed by them, and BMW and MINI are their trademarks. What we sell are parts that fit those cars, described as such. Every listing states the chassis codes and engine codes it fits, the production date range, which quality tier you are buying, the labour time the job actually takes, and whether the part needs coding to the car before it will work. Where a part is only made in plastic by the factory and fails because it is plastic, we say so and we offer the metal one.\u003c\/p\u003e\u003ch3\u003eSpecification and fitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFits: 1 Series E87 F20, 3 Series E90 E91 E92 E93 F30 F31, 4 Series F32 F33, 5 Series E60 F10, X1 E84 F48, X3 E83 F25, Mini R56 F56 where stated\u003c\/li\u003e\n\u003cli\u003eEngine: chosen above. These cars change mid production, sometimes twice in a model year, and two cars built four months apart can take different parts. Send us the last seven digits of your VIN with the order and we check the part against the build record before anything is dispatched. It takes us two minutes and it is the difference between a part that fits and a return.\u003c\/li\u003e\n\u003cli\u003eProduction dates: 2007 to 2019, and the guide specification changed in production more than once. This is a listing where the VIN genuinely matters\u003c\/li\u003e\n\u003cli\u003eQuality: redesigned where the original failed. On this site that usually means metal where the factory used plastic, or a reinforced guide where the original wore through, and the specification says exactly what was changed\u003c\/li\u003e\n\u003cli\u003ePart number: cross referenced to the original equipment number for your VIN and confirmed before dispatch. We do not publish a single number against a listing that covers several build variants, because that is how people order the wrong part\u003c\/li\u003e\n\u003cli\u003eThe failure this addresses: The N47 and early N57 diesels run the timing chain at the flywheel end of the engine rather than the front. When the chain or its guides wear, the job needs the gearbox out or the engine out, which is why a four hundred pound kit becomes a fourteen hundred pound job. The warning is a rattle from the back of the engine on a cold start, and it is worth acting on the week you hear it rather than the month after.\u003c\/li\u003e\n\u003cli\u003eLabour time: eight to twelve hours on an N47 or N57 because the gearbox comes out, five to seven on an N20 or a Mini from the front\u003c\/li\u003e\n\u003cli\u003eCoding: no coding, but the adaptation values want resetting with a diagnostic tool afterwards or the car will run on the old learned figures for a while\u003c\/li\u003e\n\u003cli\u003eAlso needed: engine oil and filter afterwards, because the swarf from the worn guides is circulating in the old oil, plus every stretch bolt in the job\u003c\/li\u003e\n\u003cli\u003eTorque: all timing bolts are single use, torqued then angled, and the figures are in the instructions\u003c\/li\u003e\n\u003cli\u003eWeight: approximately 1.3 kilograms\u003c\/li\u003e\n\u003cli\u003eWarranty: two years or 24,000 miles, whichever comes first\u003c\/li\u003e\n\u003cli\u003eMeasure before you buy: chain stretch is measurable with a dial gauge and the kit on this page. A tensioner fitted to a stretched chain buys a few months and no more\u003c\/li\u003e\n\u003cli\u003eDo it all at once: the labour is the bill on these jobs. Chain, guides, sprockets and tensioner together, or the same labour twice\u003c\/li\u003e\n\u003cli\u003eThe symptom: a rattle on cold start from the back of the engine on an N47, from the front on an N20 or a Mini, lasting a second or two and getting longer over months\u003c\/li\u003e\n\u003cli\u003eInterference engine: all of these are. A jumped chain means valves meeting pistons, which is a cylinder head at best\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat arrives\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ethe part as described\u003c\/li\u003e\n\u003cli\u003esingle use stretch bolts where the part needs them\u003c\/li\u003e\n\u003cli\u003egaskets and seals disturbed by the job\u003c\/li\u003e\n\u003cli\u003eprinted instructions with torque figures and angles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitting\u003c\/h3\u003e\u003cp\u003eEight to twelve hours on an N47 with the gearbox out, five to seven on an N20 from the front. The locking tools are essential rather than helpful, and they are on this page. Change the oil and filter afterwards, because the old oil is carrying the swarf that wore the guides.\u003c\/p\u003e\u003ch3\u003eWhich version to buy\u003c\/h3\u003e\u003cp\u003eBuy the parts together. The labour is ninety per cent of what this job costs, so fitting a tensioner today and a chain next year means paying for the gearbox to come out twice. And buy the revised guides rather than the originals: the originals were superseded because they wore through, which is the failure you are currently fixing. The N47 and early N57 diesels run the timing chain at the flywheel end of the engine rather than the front. When the chain or its guides wear, the job needs the gearbox out or the engine out, which is why a four hundred pound kit becomes a fourteen hundred pound job. The warning is a rattle from the back of the engine on a cold start, and it is worth acting on the week you hear it rather than the month after.\u003c\/p\u003e","brand":"Bavarian Spares","offers":[{"title":"N47 and N57 diesel","offer_id":58819813212424,"sku":"BVS-TCC-010-N47","price":159.95,"currency_code":"GBP","in_stock":true},{"title":"N20 and B48 petrol","offer_id":58819813245192,"sku":"BVS-TCC-010-N20","price":169.95,"currency_code":"GBP","in_stock":true},{"title":"N52 and N53 petrol","offer_id":58819813277960,"sku":"BVS-TCC-010-N52","price":184.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1064\/1037\/7480\/files\/Oil_Pump_Drive_Chain_Kit_in_Uprated_428359b5-70dd-42df-b1d8-97c8efc2aaa9.jpg?v=1790088801","url":"https:\/\/bavarianspares.com\/products\/oil-pump-drive-chain-kit-in-uprated","provider":"Bavarian Spares","version":"1.0","type":"link"}
