Dear subscribers,

I am putting the engine back together and I came = across the AC compressor. The whole unit seemed to run a little rough. =

I took it apart and found that the bearing for the = pulley to adjust the belt tension and the bearing that allows the pulley to spin = freely when the AC coupling is not engaged were completely = dry.

These were regular sealed life time lubricated = bearings from SKF. This shows me that most likely there was excessive heat that made = grease run out of the bearing.

The AC compressor sits outside the baffling and gets = heat from tube that connects the two exhausts. I wonder if I need to install = a heat shield or direct some air outside the baffling to cool the AC = compressor.

Thanks for your help
