First, thanks to the people who post good information here in the forum. Thanks to old britts for their article on gearbox rebuilding too.
I've torn down my box. everything looks amazingly clean and unworn. My bike has just under 20,000 original miles on it. I really don't abuse my bike, but I do open it up occasionally. I keep the rev's sensible most of the time. Anyway, I have a couple of questions:
I pulled both shafts and bearings. The original mainshaft bearing is "sealed one side only" bearing and the seal was on the outter side of the bearing facing the sprocket . I assume the new bearing goes the same way, but I thought that the person I talked to where I ordered it said the sealed side goes on the inner side of the bearing... This sounds wrong, so I think I misunderstood him.
Also, I don't want any leaks. should I use permatex on both gaskets??
I also bought X ring gaskets for the kick shaft and the gear selector shaft, I read that they should be set in silicone because the gear oil tends to sneak behind them. should I silicone them in ?
Also should I locktight the cover screws? they always seem to loosen, so I feel like maybe that makes sense...
** I had a scarey moment and couldn't loosen the mainshaft nut for a few hours. I Had to build a jig to hold the sprocket and the box, then added some heat to the nut and use a breaker bar to bust that nut loose,.. thankfully. I've checked numerous threads to see if my layshaft bearing was the original that blows up, and it is, so I am glad I am changing it, but the bearing that I removed is rock solid. Did bad layshaft bearings have certain years where they were bad or were all years for that bearing bad???
thanks in advance for all the help...
