Some comments and a question on replacing the power steering drive beltThe Porsche 911 Enthusiast's Companion by Adrian Streather fails to mention that the heat exchanger hot air outlet pipe, the right shock and an oil supply line all really interfere with gaining access to the lower drive belt cover plate. Once the three 10mm bolts and the lower cover are removed the drive gear and the belt are visible. The upper cover can be accessed after removing the air cleaner cover. It is retained in place by two smooth barrel shaped nuts that have an 8mm hex key socked on their forward end. (Don't try to loosen the bolts running through the pump from the rear because they only hold the pump together.) My belt had all the teeth sheared off but was still in place (and was driving the pump - except when the steering wheel what turned hard over) I pushed the belt off the top sprocket with a screwdriver and worked it out from the bottom. The new one went in just the reverse, up from the bottom with some manipulation to clear all the projections inside the cover housing. Finally engaged several teeth on the belt and carefully walked it on by turning the engine over slowly by hand with a wrench. (I have one question: Even though the refitted belt appears to be tensioned about right, there doesn't seem to be any provision to adjust it, is this true?) One last comment I run my car without the secondary muffler and would have left the hanger bracket off - except without it there is a 3/4" hole in the lower cover plate provided for the muffler's bracket upper retaining bolt. I imagine a small rock getting in through there would wreck havoc on the belt - So I am considering fabricating a new cover without the hole to replace the stock one next time around.
