rear tire and gear housing temp

Postby USMC5953 » Thu Oct 17, 2013 8:24 pm



I am courious on the operating temp of my rear tire and gear housing. After a long ride of about 100 miles I can smell the aroma of a hot tire. I touch the tire and it is hot to the touch but I can hold my hand on it without pain. When I touch the rear gear drive housing I can only stand 10 seconds or less before it starts to be painful. I am wondering how hot is normal. The fluid was changed this year and the gear hub was also lubed with molly this year. The tire is less than a year old and is at the correct pressure at 41 psi with nitrogen. I might get a lazer thermometer on my next ride and see exactly what the temp is. Has anyone ever had this concern before.

A couple of things to check, fluid level in rear drive, what type of diff. fluid are you using? also have you checked the vent on top of the rear drive its should be open to vent the rear drive housing. About the tire it will get hot and if you ride it hard it will be hot. Also check to see if its rubbing on any thing,Im sure some others may have more input. How are the bearings old worn out? Just a few things I could think up to check.---------------Hal

I have a TPMS system that shows the temperature of the tires as well as the pressure. On my 1500, the front tire stays pretty much the same as ambient temperature, maybe one or two degrees higher. The rear tire, in the heat of summer, I have seen up as high as 150 degrees.

Keep in mind that a ton of heat from the engine is dumped back there, and that wheel is tucked up between the bags where it gets almost no cooling airflow.

The bike is a 1995, it only has 19000 miles on it though. The berings could be replaced but I was going to do that this winter since I just got the bike about 4 months ago and want to get some riding done. I understand the rear tire beinghot but just concerned about the rear drive temp, it might be normal just want to make sure. The oil in the rear gear housing was purchased from honda and was requested just for that purchase. It as a black bottle with red stickers. Dont remember exactly what it said.

It probably said: "The final drive gets hot! But this oil is designed for that." :D
