{"product_id":"bmw-timing-chain-rail-14","title":"Original BMW Timing Chain Slide Rail for BMW M3, Z3 M Coupe and Roadster, and Z4 M Coupe and Roadster (2001–2008)","description":"\u003cp\u003eOn the S54 inline-six, Original BMW slide rail 11-31-7-836-344 guides the twin timing chain in the E46 M3, Z3 M Coupe and Roadster, and Z4 M Coupe and Roadster. A timing chain rail controls the path of the chain between the sprockets and limits slap and vibration, working with the tensioner to keep the chain under control. BMW calls this part the slide rail for the twin chain. It keeps the timing chain tracking properly, and after years of running the rail surface wears down. Worn tensioners and guide rails are the likely cause when rattling comes from the timing case. The rail weighs 44 g and is made in Germany.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eThis number entered production in October 2004 and supersedes the earlier 11-31-7-830-867. BMW rates the change as exchangeable retrospectively, so the current rail is the correct replacement for engines built with the earlier number as well. One part covers every S54 application, including the M3 CSL and the M3 Convertible, with no coupe or roadster split on the Z cars.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: BMW (Original BMW Part)\u003c\/li\u003e\n\u003cli\u003ePart number: 11-31-7-836-344\u003c\/li\u003e\n\u003cli\u003eBMW part name: slide rail, twin chain\u003c\/li\u003e\n\u003cli\u003eEngine: S54\u003c\/li\u003e\n\u003cli\u003eWeight: 44 g (1.55 oz)\u003c\/li\u003e\n\u003cli\u003eProduction start: October 2004\u003c\/li\u003e\n\u003cli\u003eSupersedes 11-31-7-830-867, exchangeable retrospectively\u003c\/li\u003e\n\u003cli\u003eSold individually, made in Germany\u003c\/li\u003e\n\u003cli\u003eWarranty: 24 months on Original BMW Parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat causes rattling from the timing case on an S54?\u003c\/strong\u003e\u003cbr\u003eRattling there is most likely from worn tensioners and guide rails.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this replace 11-31-7-830-867?\u003c\/strong\u003e\u003cbr\u003eYes.
