I am experienced in wren 54 repair but not jetcat. I have recently bought a second hand jetcat P70 ( I suspect there has been someone in here before me) and have had to replace the rear bearing. I noticed that the front comressor bearing has three wavey washers behind it and the rear bearing only one. This seems strange! The compressor is also rubbing on the front intake. Can anyone confirm that there should be two wavy washes behind each bearing as this would move the compressor to the back of the engine away from the front intake.
