Al,
Sorry I couldn't provide the chart you were seeking. I actually downloaded a copy in case someone asks me the same question again before I die. That chart may be very important to the maintenance supervisor of a huge production facility, but being pragmatic, I don't see the need for someone who is going to grease a few cars and tractors. My first question would be, how do you know what grease is already in the fittings you intend to lube? If you have carefully documented it, why change? I just serviced a wheel bearing yesterday. I cleaned the spindle and hub thoroughly and repacked it with gooood old wheel bearing grease. It should be good for another 100,000 miles. Call me an old fa*t, but I just don't see the point. Now if I worked for NASA and had to lube the tractor that hauls the shuttle from the VAB to the launch pad, that may be a different story. That thing carries an incredible load at walking speed on a road bed that is several feet thick. EP grease would be called for in that application.
