discojmz Posted September 11, 2008 Share Posted September 11, 2008 my apologies if this has been covered before but I couldnt find the info I was looking for Im after a measurement on the full outer diameter of the alternator pulley on a discovery 200tdi part number RTC5847 but i cannot find out the diameter. this is to find out once and for all whether the pulley on my alternator is correctly sized and therefore whether my rev counter is telling pork pies. many thanks in advance Jim Quote Link to comment Share on other sites More sharing options...
