Manufacturer Part Number: 534 0075 20. Part Manufacturer: INA. The tensioner may have to be adjusted manually during fitting though many, known as automatic tensioners, have springs which automatically adjust the tension.
Although not fitted yet, the build seems more robust than the original, particularly the arm that releases the tension. The original arm has an H section, but this one is solid, with a hole to place your 4mm locking pin through. I guess the original has a special tool to mate with the H section.
