Just to give some of the others that have a ACERT a little notice. Check your air compressors intake fitting...mine pulled the threads out of the compressor head last night. The fitting and hard line are to long and heavy from what I see and Bendix Tech Support confirmed my idea. The guys at Bendix commented that they have had this issue since the motors were released and that CAT was told they needed a fitting that had more threads (mine was only in about 4 threads:gaah). Now I'm faced with replacing the compressor to be on the safe side since metal shavings went through the thing. The first 2 pics show me rocking the fitting side to side while its still "screwed" into the head. The last 2 I'm trying to show how few of the threads the fitting actually uses. My simple fix to get me rolling again was to JB Weld the fitting back onto the head. I did this cause a Pete dealer wanted $700 after the core charge for a new compressor:thumbdown. I can get the same unit for $490 at the house.
