My MicroBlue experience

Yes, a little, still cooler than stock. I talked to Craig a MB about the situation, seems the installer wasn't following stemco's adjustment procedure. I will review them as Craig has since advised them to do it correctly or,..........

 

Just curious as to how you can determine how much of that heat is from the bearing friction vs. conducted to the hub and bearings via the brake drums? Also, could the tractor hubs be running hotter than the trailer hubs due to the heat conducted down the axle shafts and housing from the differentials?

 

Yeah, I've been rerunning our conversations in my head and that's what I've come up with too. Didn't back off the spindle nut enough.

 

I'm assuming that I'm testing my hub temps on the trailer the same way anybody would be (drive it for awhile, then jump out and hit the hubs with an IR thermometer gun). An MB hub should have a cooler starting point than a non-MB hub. So the end result should be cooler as well.
And the driveline hubs/axles are sitting in a larger pool of oil, which should keep them cooler than dead axles.
I don't think, in real world situations, you can seperate out where the heat came from. Just looking at the end results.

 

How do you figure MB would be cooler at the start?

THe drives will be warmer do to the heat coming from the differential gears/bearings, heating the oil, therefore heating the drive wheel bearings. Check the temp. of the differential at the center, mine was about 150, trailer temps will reveal the front temps cooler than the rear tandem nubs, about 10 different.

 

well whatever! I don't have an answer for you than is that better?

have you read over the micro blue material from micro blue? Did you see where they're getting reports of hub temperatures 10 to 25 degrees above ambient after installing MB?

 

I think the only way to know for sure what they do or don't do as far as temperature is to replace both sets of bearings on the same side of a set of tandems, one new with the coating, and the other new bearings out of the box without any coating, remove the brakes and run it down the road. Then stop and check the temps, comparing trailer hubs to drive/steer hubs means nothing. There are far to many differences between them for anything to be conclusive.

 

I don't understand your reply. Yes I've read all the information I could find on MB before I spent my money. What is this whatever BS about?

 

What I've done is compare my temps with another cascadia.
I'm not comparing trailer to drives to steers, I know you will get different readings on all 3. Thats what I'm saying.
I've noticed the front tandem is always about 10 degrees cooler than rear, even on some other truck, I believe its cooled better as it's receiving more air.
The drive temps at the hubs are affected by the heat generated at the differential.

 

Whatever = I don't feel like arguing about it.
