lube leak - any ideas?

I have a 2001 beartracker. Just recently, it has started to spit out oil or lub from one of the tubes that is located just behind the gas tank and in front of the seat. I was able to isolate the "leak" to the tube coming from the rear gear box or transaxle. So far it seems to be a small amount of lube that leaks out - maybe a tsp at a time. Today I warmed up the motor and then drove the tracker slowly to try and isolate the leak. I ran and drove it for about 20 min with no problems. Then finally during some driving it "spit" out a bit of lube for this tube. It seems to be intermittant and not very much but it is getting messy and drips onto the exhasut.

I checked the rear oil and it appears full. I have not added any lube there so it is not over full either. Prior to this, it was running fine and hand no leaks or problems.

This is Minnesota and the weather has been cold if that has any effect. I have always warmed it up and drove slow prior to use.

Any ideas as to the cause or the cure for this problem? What is the tube there for ? breather of overflow?

Thanks for nay help or advise.

Re: lube leak - any ideas?

sounds to me like it's just a vent tube. When the rear diff heats up, the air expands, and has to have somewhere to go, so it pushes out the tube pushing any small ammount of oil that gets slung into the opening by the spinning gears etc. It would make sense that you noticed it now more than before since the air inside the diff is colder (meaning there is more air in there)before you start to ride, and that gives it a larger temp difference hense more expansion once it warms up. I would just check the oil level regularly, and not worry about it too much unless you notice a big increase in how much is spilling out the tube. as for it dripping on the exhaust, ,you should be able to find somewhere better for it to drain, and just lightly zip-tie it to the frame to hold it (being careful not to pinch the line closed.

Re: lube leak - any ideas?

Thanks John,

You confirmed the local dealers (and mechanics personal experience). Apparently when it is cold like this, the oil gets coated on the inside of the housing and then when things heat up, it "burps" a small amount out that was plugging the vent hole.

I'm glad it doesn't seem to be an internal seal or anything.

My next step is to do exactly as you explained.
