SUMATE belt tensioner 504046191 is a complete tensioning component for engine belt systems used across several European commercial, agricultural and industrial diesel platforms. The existing product records also identify 5001860058, 99436331 and 99471920 as cross-reference numbers.
The product images show an integrated tensioner consisting of a pulley, tensioning arm and spring-loaded housing. Its purpose is to apply controlled tension to the belt while accommodating normal movement and load changes during engine operation.
This belt tensioner helps maintain the required belt tension and alignment within the engine belt-drive system. A correctly matched tensioner supports stable belt operation and helps reduce belt slippage, vibration, abnormal noise and uneven wear.

Yes. 504046191 is the primary OE number for this product. The other numbers shown on this page are listed separately as cross references.
The product images show a complete belt tensioner with an integrated pulley, tensioning arm and spring-loaded housing. It is not an independent idler pulley.
The current product data contains inconsistent timing-belt terminology. Because the available information does not conclusively confirm a timing-belt application, the product is identified as a belt tensioner. Always compare it with the original part before ordering.
The current product information associates it with DEUTZ, DEUTZ-FAHR, IVECO, IVECO MAGIRUS, FIAT, ASTRA, IRISBUS, MAGIRUS-DEUTZ and NEW HOLLAND applications. Exact fitment must be verified by OE number and original configuration.
