Sorry to qualify for this forum, but here goes, it happened Mon 8-1-05.
RV particulars: 2004 Winnebago 39K Journey
Driveline (Engine, Transmission):Cat 7, 330hp, Allison 6-spd
Miles:17500
Year:Built 12/03, bought new 4/04
Break Down Description: Suddenly Overheated, after cooling restarted, drove 1 mile overheated again. Had to be towed 40 miles to Sparks, NV.
Cause:Horton Fan Hub failed. Bolts, bearings, failed and it separated from engine.
Outcome: Still in Caterpillar Shop in Sparks, awaiting parts (7) coming from 5 different areas of US and Canada.
THE CATCH IS...Kenworth (through NHTSB) issued a recall for this same engine and fan hub combination in APRIL 2004! Had it been recalled by Caterpillar or Winnebago, I could have avoided this costly breakdown. BEWARE Other C-7 Cat drivers...
