Electromaax Yanmar Belt Tensioner and Idler Pulley

$389.00

SKU: Belt_Tensioner_Idler Category:

Description

To further enhance the performance of our SM line of alternators, we now offer a belt tensioning device specifically for Yanmar marine engines. This simple device eliminates the need to tension the belt using a stick or screw drive that requires the installer to have three arms. Now with the turning of a bolt you can easily achieve the perfect belt tension for your Yanmar engine.  TENSIONER WILL NOT WORK ON ANY V-BELT CONFIGURATION!

Key Benefits:

The belt will never slip as the alternator is held firm.  It eliminates slippage and greatly increases belt life. Simple replacement bolt-on, no additional brackets required, and Universal fit on most Yanmar marine engines. Fits under plastic belt cover. Engine runs quieter. Maintenance free performance when belt is properly installed and tensioned.  The tensioner on its own will not eliminate belt dust!

Note

For higher amperage alternators (over 100 amps) this devices needs to be combined with our Serpentine Pulley Upgrade Kit manufactured by ElectroMaax for your specific Yanmar engine.
