Hopefully bringing this thread back to life! Just had the ZF power steering set up fitted to my '76 109 which has a Disco 1 200 Tdi fitted. Steering is spot on, positive and not too light but I am having an ongoing problem with screaming belts - or is it the alternator - which is new and the correct one? I have the normal 200 Tdi power steering set up with a belt driven off the crank turning the water pump and the power steering pump and a smaller belt running off the inner pulley on the power steering pump which turns the alternator. I have checked and double checked that the belts are the correct ones and that they are in line using a straight edge and are nicely tensioned without being too tight. I am now on my third set and the howling persists - in particular on full left lock and when coming to a standstill, the alternator comes to a halt and the red warning light comes on? I've searched online and had many suggestions but the problem persists. I could use some belt dressing but wouldn't this just mask the problem? Anybody had a similar situation and found a solution?
