So, on my (new to me) '83 944 I have looked through the maintenance records and can't find any recent indications of a timing belt replacement, so I'm going to assume it's been long enough and get a new belt and go to town. The only thing is, I know that this job requires a special tensioner that is supplied by Porsche and very costly. When I search for the tensioner for my year one of the first results is this: 83 1983 Porsche 944 Timing Belt Tensioner - Engine Mechanical - Ruville - *********

It looks quite different to me than the Porsche device, can someone please enlighten me to what's going on?

Perhaps the design was changed during a certain year? I must confess I don't know very well how the operation of the timing belt works
