BMW Timing Chain Tensioner / Preload Tool

Proper timing chain tension is critical when servicing your BMW's timing or VANOS system. This BMW Timing Chain Tensioner Tool provides a simple, precise way to apply and control timing chain preload during engine service.

Whether you're replacing timing chain guides, resealing the timing cover, removing the VANOS unit, or performing camshaft and timing work, there comes a point when the timing chain needs to be properly tensioned before everything can be set and reassembled.

While there are plenty of improvised methods for applying chain tension, German Auto Solutions developed a purpose-built solution for the job.

This precision CNC-machined tool threads directly into the factory timing chain tensioner location on the side of the engine block. Once installed, simply turn the large knurled adjustment knob to increase or decrease pressure on the timing chain as needed.

No makeshift tools. No guessing. Just a simple, repeatable way to properly preload the timing chain during service.

Why Use a Timing Chain Preload Tool?

The factory timing chain tensioner uses spring and oil pressure to maintain proper chain tension while the engine is running. During engine service, however, a controlled method of applying chain tension is needed when setting up the timing system.

This tool temporarily takes the place of the factory tensioner and allows you to manually control the amount of pressure applied to the timing chain.

Simply thread the tool into the tensioner bore and use the knurled knob to apply or release tension as required by the service procedure.
