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
