hub temp

[2011 keystone]

I just bought a digital temp gauge and was waundering what temps I should expect to see after running 65 MPH for a hour or two. My TT weighs about 7500lb fully loaded. Thanks

Too many variables involved for a "standard" temperature...sunny side, shady side, humidity, ambient temperature, degree of braking in the last 30 minutes, etc.; a whole host of things that can affect hub temperature readings. The accuracy and repeatability of your particular infrared thermometer also come into play; not all thermometers are created equal

What you are looking for is the "out of norm" reading. If 3 out of 4 of your bearings read, for illustrative purposes only, 135 degrees and one reads 175 degrees, then that wheel assembly may be suspect. Could be brakes, could be tires (low tire pressure will generate more heat), could be bearings. It is the exception to your "average" reading at that moment that should elevate your attention to that particular wheel. If that wheel starts giving you consistently higher readings than the rest of them and after several readings at different times and after you've verified tire inflations, then is the time to start to figure out what is going on in that wheel; brakes or bearings...

I use an infrared device religiously, but, they are only a tool to indicate a potential problem in the making and not a spot indicator of eminent failure based on an actual temperature.

I couldn't have said it better .... so .... X2, Hank (I also check tire temp and through the spokes I check the drums .... one cool drum could mean that brake not working) Great little tool, sure beats burning the back of the hand. ... The DW smacks me when I use it on her.

Times three for me too but iam stupid i still use my hand on the tires been lucky so far they stay cool but 60 is my limit for speed yep people pass me telling me i am #1 but my rig is always rite side up!!

OK thanks guys. I will just keep a record of my temps for awhile that way I will have a average temp. So I will no if one is running way to hot
