Tensioner

The belt tensioner is responsible for keeping proper tension on the belt at all times and during all running conditions. When the tensioner ages, it loses some of the spring tension and can allow the belt to slip if left unchecked. Turner Motorsport carries Genuine BMW and high quality aftermarket options to get you back on the road in no time.

Maintaining your BMW E6X, E8X, E9X, or Z4 engine health is paramount to ensure optimal performance and longevity. Two crucial components that require periodic attention are the cam bearing ledge and valve cover gasket. Regular servicing of these components, along with other critical elements such as the camshaft O-ring, chain tensioner (with gasket), and oil filter, is imperative to keep your BMW running smoothly. Included in Kit: 1 - Cam Bearing Ledge - Exhaust 29 - Torx Bolt 1 - Genuine Cam Bearing Ledge - Intake 1 - Genuine Cam Bearing Ledge - Exhaust 1 - Valve Cover Gasket 4 - Genuine Camshaft O-rings 7 - Genuine BMW TwinPower Turbo 5W-30 Engine Oil 1 - Assembly Lube 1 - Chain Tensioner - With Gasket Ring 1 - Hengst Oil Filter 2 - Collar Screws Cam Bearing Ledge: The cam bearing ledge is vital for proper camshaft support and lubrication. Over time, wear and tear can compromise its effectiveness, potentially leading to camshaft damage. Servicing this component ensures that your camshaft operates optimally, preventing costly repairs. Valve Cover Gasket: A well-maintained valve cover gasket is essential to prevent oil leaks and maintain proper sealing in the engine. Ignoring gasket issues can lead to oil contamination, loss of engine performance, and even engine damage. Camshaft O-Ring: The camshaft O-ring helps maintain proper oil pressure and prevents oil leakage. A deteriorated O-ring can result in oil seepage, leading to lubrication issues that affect engine performance and longevity. Chain Tensioner (with Gasket Ring): Proper timing chain tension is crucial for engine synchronization. Servicing the chain tensioner and its gasket ensures correct timing, preventing potential engine misfires and damage. Oil Filter: Regularly replacing the oil filter is fundamental to maintaining clean engine oil. Clean oil is essential for lubrication and heat dissipation, safeguarding the engine against wear and tear. Kit is for these BMW models: E60 / E61 - N54 3.0L E82 / E88 - N54 3.0L E90 / E92 / E93 - N54 3.0L Z4 - N54 3.0L

This is an OEM Ruville Idler Pulley, also known as the roller pulley or deflection pulley. The idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).
