Yeah Chris I think people have had problems with this, and I suspect a good bit of their poor experiences were due to their or a previous fixer's lack of understanding. Perhaps there is room for criticism of the design, which is what I gather you are looking for, using terms like "poor design, problematic, brilliant, (sarcastically) UFB (is that a TB term?)" and I would agree the whole shebang is a bit of a thorn in the side of an otherwise maintainable 240 even without the tensioner and jack screw ... but you see what they were up against if you follow the evolution of that three-pulley arrangement needing two belts from the originally tiny alternators needed in the 70's. Fixed it on the 7/9 of course.

To add to this, the drawings are little help to explain how the bushing expands to grab the inside of the sleeve when the bolt is tightened, and confusion over this and the placement of the bushing results in M8 bolts breaking out the cast iron and the rusty M6 jackscrew snapping in the lock.

Anyhow, when you figure it out, let us all know, because no one I've heard yet has returned from poly or solid aluminum solutions to say they were happy for many years and miles afterward.
