On tightening/tensioning the belt - on my new M25XPBengine I can't use the belt tensioner that I had for the old M25XP engine. I am able to push on the alternator with one hand and then tighten the bolt with the other. I can't fit the belt tensioner in anymore!! (I've got the older large case Balmar alternator)
A few thoughts
I can hear a slight clicking sounds when a over the pump up and down it's a very slight noise but it's there. Also nothing is coming out of the weeping hole (I had the paper in) and after I cleaned up the discolouration in the photos with CLR there has been no further discolouration.
I'm a bit puzzled at this point...
