CCEC K19 Cummins Engine Parts Lever Idler 4009442 3410131
The Idler Lever, also known as the tensioner lever, is a truck component that plays a crucial role in maintaining proper tension on the engine’s timing belt. It is typically attached to the engine block with a bolt and functions by applying pressure to the timing belt. This helps ensure that it remains in place while the engine is running and prevents it from slipping or jumping teeth on the sprockets. The Idler Lever is an important part of any truck’s engine system and should be regularly inspected for wear or damage. If it becomes worn or damaged, it should be replaced promptly to prevent potential engine damage or failure.
