Welcome from Mexico, with all the bikes you have had for sure will be good to hear your comments regarding the S10, for me it is being a great bike! it is like a train / farm tractor, easy to work with and very reliable!!
He told me he hadn't and for as little as he used it I believe him. 400 more miles since I found the leak, still dry......so strange.I wonder if the lube you found on the wheel was spillage from the PO changing the fluid?
My guess is that your bike sat so long the seal slightly deformed and the first time(s) out the slight egg shape let a few drops get past. Heat up the seal and flex it with some more riding and it ought to lose the egg shape to seal back up.He told me he hadn't and for as little as he used it I believe him. 400 more miles since I found the leak, still dry......so strange.
You should not be concerned until it stops leaking. Afterwhich you should add more gear oilAfter an 900 km weekend of mostly road riding with some gravel roads (including river crossings). I found oil around my diff. (see photos). The diff felt warm (40-50 degrees C)..
Should I be concerned? Should I do anything?
I found a YouTube video on how to change the oil seal but I'm a little leery about drilling into the old seal and inserting a sheet metal screw without damaging what's behind the seal. Since you've changed a few of the seals, approximately how deep do you drill into the old seal? Also, if I understood correctly, the seal has a metal band inside it and this is what I need to set the screw into? Is this correct? Thanks for your guidance.Its easy.. The seal is available and the "how-to" is on You-Tube ! Ive changed a hand full... There is no rhyme or reason to the ones that start leaking... Miles / year bikes are all over the board...
