Also known as a <strong>slide rail, chain guide, guide rail or tensioner rail<\/strong>, it helps guide and control the timing chain as it operates inside the engine.<\/p>\n<p>BMW OE number <strong>11317592850<\/strong>, written as <strong>11 31 7 592 850<\/strong>, is the updated replacement for earlier BMW timing-chain guide numbers <strong>11317516079<\/strong> and <strong>11317584651<\/strong>. BMW parts catalogues identify it as a genuine BMW <strong>slide rail \/ timing chain guide<\/strong>.<\/p>\n<p>The guide rail is designed to work with the timing chain and tensioning system to maintain proper chain movement. A worn or damaged guide can contribute to excessive timing-chain movement and, in severe cases, allow the chain to move out of its intended timing position.<\/p>\n<h3>BMW Part Details<\/h3>\n<ul>\n<li><strong>BMW Part Number:<\/strong> 11317592850<\/li>\n<li><strong>BMW OE Format:<\/strong> 11 31 7 592 850<\/li>\n<li><strong>Product:<\/strong> Timing Chain Guide \/ Slide Rail<\/li>\n<li><strong>Position:<\/strong> Upper timing-chain guide<\/li>\n<li><strong>Brand:<\/strong> Genuine BMW<\/li>\n<li><strong>Replaces:<\/strong> 11317516079<\/li>\n<li><strong>Also Replaces:<\/strong> 11317584651<\/li>\n<li><strong>System:<\/strong> Engine timing \/ valve train<\/li>\n<\/ul>\n<h2>BMW Timing Chain Guide Function<\/h2>\n<p>The timing chain is responsible for synchronizing the crankshaft and camshaft(s), allowing the engine&#8217;s valves to open and close at the correct time.<\/p>\n<p>The <strong>11317592850 slide rail<\/strong> provides a controlled surface for the timing chain and forms part of the chain-guiding system. It works together with the timing chain, tensioner and other guide rails.<\/p>\n<p>A worn timing-chain guide may contribute to:<\/p>\n<ul>\n<li>Timing-chain rattling<\/li>\n<li>Increased chain movement<\/li>\n<li>Noise from the timing-chain area<\/li>\n<li>Timing-related fault codes<\/li>\n<li>Poor engine operation<\/li>\n<li>Incorrect valve timing if severe wear allows the chain to move excessively<\/li>\n<\/ul>\n<p>A proper inspection should normally include the <strong>timing chain, tensioner and guide rails<\/strong> rather than replacing only one component without checking the rest of the system.<\/p>\n<h2>BMW Model &amp; Engine Applications<\/h2>\n<p>BMW 11317592850 is used across a wide range of BMW petrol-engine applications. Catalogue data identifies applications including <strong>3.0L petrol engines, selected 2.0L engines and later 3.0L petrol engines<\/strong>.<\/p>\n<p>Examples of documented applications include:<\/p>\n<ul>\n<li><strong>BMW 1 Series E81\/E82\/E87\/E88<\/strong><\/li>\n<li><strong>BMW 3 Series E90\/E91\/E92\/E93<\/strong><\/li>\n<li><strong>BMW 5 Series E60\/E61<\/strong><\/li>\n<li><strong>BMW X1 E84<\/strong><\/li>\n<li><strong>BMW X3 E83<\/strong><\/li>\n<li><strong>BMW X5 E70<\/strong><\/li>\n<li><strong>BMW X6 E71<\/strong><\/li>\n<li><strong>BMW Z4 E85\/E86\/E89<\/strong><\/li>\n<\/ul>\n<p>Specific engine applications include selected <strong>N52, N55 and N20<\/strong> petrol engines. For example, the part is listed for BMW E60 525i\/528i\/530i with N52, E70 X5 applications, E71 X6 xDrive35i with N55, E84 X1 sDrive28i with N20, and selected E82 128i\/135i applications.<\/p>\n<p>RealOEM also lists the part in the timing-chain system of the <strong>BMW Z4 E86 3.0si<\/strong> and documents the earlier part numbers that it supersedes.<\/p>\n<h3>Important Fitment Note<\/h3>\n<p>Because <strong>11317592850 is used across several BMW engine families<\/strong>, the exact application must be confirmed using the vehicle&#8217;s <strong>VIN\/chassis number, engine and production date<\/strong> before ordering.<\/p>\n<h2>Why Replace a Worn Timing Chain Guide?<\/h2>\n<p>Timing-chain guide rails are exposed to continuous chain movement and engine operating temperatures. If a guide becomes worn or damaged, it can affect how the chain is controlled.<\/p>\n<p>Replacing a worn guide can help:<\/p>\n<ul>\n<li>Maintain proper timing-chain guidance<\/li>\n<li>Reduce excessive chain movement<\/li>\n<li>Support accurate engine timing<\/li>\n<li>Protect other timing-system components<\/li>\n<li>Restore the correct timing-chain arrangement<\/li>\n<\/ul>\n<p>ECS Tuning recommends replacing the guide when wear is detected because damaged timing components can allow the chain to skip timing and potentially result in more serious engine problems.<\/p>\n<h2>Genuine BMW Replacement<\/h2>\n<p>The <strong>Genuine BMW 11317592850<\/strong> is the current replacement for earlier guide-rail numbers <strong>11317516079<\/strong> and <strong>11317584651<\/strong>. This makes it particularly important when replacing an older timing-chain guide during an engine repair or timing-chain service.<\/p>\n<h2>Buy BMW Timing Chain Guide 11317592850 in Nairobi<\/h2>\n<p>Looking for a <strong>BMW timing chain guide in Nairobi<\/strong>?<\/p>\n<p><strong>Bavarian Trading Company Limited<\/strong> supplies genuine and OEM-quality BMW spare parts in Nairobi.
