This part is listed by BMW as BMW part number 11311280960 (11 31 1 280 960) and is described as the pin that the timing belt tensioner stops against on the M20 engine used in E21 323i, E30 325e/325i, E28 528e, and E34 525i. This pin is essential for guiding and supporting the timing belt tensioner. These do not typically wear out or require a replacement but any wear on the shaft will lead to the tensioner slacking more than it should.
