It maintains proper tension on the drive belt that connects the engine to the alternator, preventing belt slip, premature wear, and charging system failures.\u003c\/p\u003e\n\n\u003cp\u003eProper belt tension is necessary for reliable alternator operation. On Wacker Neuson generator models, service procedures specify checking belt deflection and adjusting tension as part of routine engine maintenance. A worn or failed tensioner can result in insufficient belt tension, leading to belt slippage, reduced alternator output, and accelerated belt wear. Replacing the tensioner with a genuine OEM part restores correct tension geometry without requiring manual adjustment through locknut and adjust nut procedures.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the following Wacker Neuson models:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eG100 (5100071899)\u003c\/li\u003e\n  \u003cli\u003eG70\u003c\/li\u003e\n  \u003cli\u003eST35 (S06-4)\u003c\/li\u003e\n  \u003cli\u003eST40 (S06-5)\u003c\/li\u003e\n  \u003cli\u003eST45 (S06-6)\u003c\/li\u003e\n  \u003cli\u003eST50 (S06-7)\u003c\/li\u003e\n  \u003cli\u003eSW24 (S06-1)\u003c\/li\u003e\n  \u003cli\u003eSW28 (S06-2)\u003c\/li\u003e\n  \u003cli\u003eSW32 (S06-3)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAlways stop the engine, remove the key, and allow the engine to cool before inspecting or replacing the belt tensioner.
