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

Pulleys begin to squeak once they are reaching the end of their life span and the tensioners can fail, no longer applying enough tension to the accessory belt. If not replaced, tese can seize up and lead to a long host of problems that would leave you stranded on the side of the road. Prevent this with routine maintenance and replace your belts and pulleys every 50,000 miles to ensure continued reliability.

Hydraulic Belt Tensioner for E36 4-cyl models with M42 engine. This is the oil-filled tensioner that keeps the main drive belt in the proper tension. Over time the piston seals inside allow fluid to leak out. The tensioner becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.

This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.

This high-quality replacement from Bremmen Parts is designed for exact fitment on your BMW. Whether you're looking to complete much-needed preventative maintenance, or replacing a failed roller, choose this component from Bremmen Parts for a lasting repair.

This is an OEM INA tensioner pulley, also known as the adjusting pulley and lower pulley. This pulley is mounted on the belt tensioner near the center of the belt assembly. The upper and lower pulleys are known to be the primary sources for 'belt squealing'. This 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).

This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines).
