Product positioning and procurement value

The GATES 39179 belt tensioner is suitable for procuring automotive engine transmission system parts and can be used as a single item for initial verification of part numbers, dimensions, and installation locations. Product number 39179 is suitable for wholesale customers, parts distributors, and repair kit suppliers who need to organize their purchasing lists by brand number, OE number, or cross-number.

This product allows for procurement confirmation by combining basic dimensions and multiple reference numbers, facilitating the creation of product files, the organization of replacement numbers, and subsequent replenishment management. However, cross-numbers do not equate to confirmed vehicle compatibility information; further verification based on vehicle data is still required for practical application.

Core Advantages and Customer Benefits

  • The brand and product number are clearly defined: GATES brand, product number 39179, which facilitates unified identification in the purchasing system, quotation and inventory data.
  • The basic dimensions are clearly defined: outer diameter 76 mm, width 31.5 mm, inner diameter 17 mm, which can be used for preliminary comparison with the original parts and installation positions before placing an order.
  • Reference number coverage: Supports verification of OE AL3E 6B209 AA, OE AL3E 6B209 AB, OE AL3E 6B209 AC, OE AL3E 6B209 AD, OE AL3Z 6B209 A, DAYCO 89665 and MOBEAR internal number 9TQ0879.
  • Suitable for batch data management: Multiple numbers can be used for product catalogs, customer inquiries, cross-referencing, and replenishment list organization, reducing communication back-and-forth during the number confirmation process.
