Dennis Savarese) ________________________________ Message 1 _____________________________________ Time: 11:22:16 AM PST US From: JON Subject: Yak-List: CJ6 MG Wheel Bearing Question Looking for a little assistance on MG wheel bearings for a stock CJ with original wheels... The current MG bearings are stamped with 7508 & 7509. I was told that I could replace with Timken brand part numbers 32208 and 32209. Can someone verify? Are there other brand names and part numbers? It would also be helpful if you could list a national chain store to purchase... i.e. Advance Auto, O'Reilly, Napa, etc...

This is the weight that the CJ-6 can be flown *aerobatic*, analogous our to aerobatic category. If flight loads were limited to +4.4 , the CJ could fly at 3471 lbs in the Utility category (if it were Standard Certification). I believe somewhere in between happens more often than not with long range fuel, and other add-ons. Many CJ's were converted or built as forestry and coastal patrol workhorses. Gary Nunn has one, I believe it holds 90 gallons of go juice in stainless steel tanks, that's a 540 lb fuel load. Others were even converted to Ag sprayers weighing up to 4100 lbs! Of course in the Experiment-Exhibition Category, every flight is a test flight.

Dennis Savarese" Craig, Correct me if I'm wrong, but if an airplane has a standard certification like a Cessna or Piper single, if one looks at the Weight and Balance envelop, the utility category is where it is approved for certain aerobaticmaneuvers which is always less than the normal full gross weight. Thus in the case of the CJ, wouldn't you call the 3471 pounds the normal category and the 3086 pounds the utility category since this is the weight the airplane is approved for aerobatics? Dennis A.
