Slow oil drip after front sprocket change

My Gen2 has always been tighter than a drum. No leaks. Changed the front sprocket the other day. Took it off with an electric impact driver. Put the nut back on and torqued by hand. The only other semi-violent act that occurred in this operation was the tapping of the washer edge down.

Anyway, now I have a slow drip falling on the floor somewhere an inch or two behind the sprocket area. Like a small drop every day or two. What could I have done here? Is there a seal on the shaft that I could have buggered up? It was pretty cold in the garage when I was working on it. Not sure if that matters.

Just pretty bummed, because, like I said, thing has always been tight and all I did was change a damn sprocket, now I have a drip.

Any ideas here?

Ive changed them on dirt bikes and it was no big deal, really. I believe the seal was less than 10.00.

The impact gun on, countershaft sprockets, is not my favorite tool. Then again, I'm sure you were screwed, just like I was. I can almost guarantee Andre The Giant tightened mine, at the factory, before the bike was sold. Then he did the oil filter....

Check that shaft for excessive play. Its not a real common thing to have leaking and it makes me wonder if something was damaged when you used the impact gun.

All I did, for mine, some seal lube, then slid the new one in place.

I'm not seeing a seal on that shaft in the schematics. Not really sure what to think.

no, shift shaft seal. larger one, 92049. look at 10 transmission on ebay, countershaft seal aparrent. like u i remove engine sprockets with electric impact. i did have one on a bike that leaked a little oil after changing sprockets. couple of drops on floor for just a few days, then stopped. unsure, maybe impact shocked seal allowing oil to seep by loosening. that seal has a spring around the sprocket spacer opening to maintain tension against spacer to be oil tight. it can be replaced if careful without splitting cases with sprocket/spacer removed. it's basically metal fabbed/rubber coated. can be drilled with small hole to side and jerked out, good news is its got a slight taper that helps it go back in cases. i've done couple over the years. me, i'd give it a day or 2.

Kinda thinking the same thing. Maybe take it out for a little shake down. See what happens. Thanks for the advice.

You wont get that seal out without damaging mate, if your gonna pull it you need a new one to fit with a litle gasket sealent to make sure.

All good. I'm just thinking if I get things good and hot, it might seal back up.
