Couldn't find a bushing but what I did find was one of those cable tv splitters, I ground the threads off one of the male ends and drilled out the plastic insulator centre, tapped it into the hole and fit perfect. Just gotta tape up the drill bit for depth and I'll give it a go after work today.

Ok all done, only problem I ran into was the tap wouldn't goto the depth of the hole I drilled so I just took my extra tap and ground the none cutting portion of the tap away and it worked out well. For the drain plug I didn't realize it but there was probably near 3/4 inch of thread in the hole that had never been used because the plug was so short, I got a tap and cleaned up the threads and got a longer bolt and plastic washer and although its not magnetized it will do the job. So now I'm going to replace all the seals in the old tranny ( even though it had no leak issues) and get it ready if I need to swap out the tranny. I plan on going in one more time to see if I can seal up the main seal and if it doesn't work the old tranny will be going back in, getting real tired of oil under the bike.

It gets old very quickly does having oil under your bike....unless you own an old Triumph or BSA in which case its a sign that you don't need to check the oil yet....

I meant to ask about these orings that are on my old tranny mainshaft, there not showing these orings in the parts book so I'm thinking there an added idea from from someone. Anyways my old tranny always worked well and never leaked, perhaps they were added for a cushion against the main gear or used to help stopping oil seepage.

Never seen them before, I would imagine it might be to stop a quadrant seal leak but no-one is that retarded as it would stop oil reaching the needle bearings inside the output gear.....

Main gear needle bearings are in good shape as they were when I replaced them when I rebuilt tranny last time, but could the big main bearing be affected? It seems a bit dry/noisy.

Having thought about it, those needle roller races can get loose in the gear and I have seen them creep up the gear until there is no space between the two sets of rollers....maybe these were put in to stop the rollers creeping back out of the gear?
They wouldn't affect main bearing lubrication and by the sounds of it haven't affected the needle roller lubrication......must be a CIA thing to record your brainwaves or a tracking device...I suggest you line your helmet or bandanna with tinfoil mate.....

I hear you Spanners, we're always under the watchful eye.
I had a thought when I was at work today, I was thinking what was the only thing different in the way I did the seals on my old tranny and the new one and the only thing I could come up with is the guy that owned the tranny is the guy that put the big seal , quad and mainshaft seal and I did the shifter seal. The other thing I could think of is I usually use a torque wrench for the pulley nut where as he insisted to use the electric impact he brought over so guess what I'm going to do ? Yep pull the pulley again and reinstall a new seal and use my torque wrench to tighten big nut. After all its actually the big nut that tightens the pulley which tightens down the spacer which squishes the quad seal right?

Once you get it torqued over about 30-40 ft/lbs it doesn't really affect the quad seal much as to get to that torque its gotta be hard up against the sprocket and (from the inside) the bearing inner race.....torque over that is pretty much academic and in anycase, lots of people use a pnuematic rattle gun to torque the pulley nut without it leaking.....the leak is likely to be a slack fit between main seal and output shaft for some reason, micrometer time methinks...or maybe the seal is not correct.

Ok anyone ever had the misfortune of installing and oil filter on an auto and found that the old rubber seal got stuck in place and the result for a stream of oil? Well I would imagine the same thing would happen installing a quad seal without removing the old one, ya that's right 2 quad seals, this is why my bike never goes to a shop and Im the only one that wrenches on it, well except for someone who knows it all steps in and insist on installing the big seal and 2 quads. And also when I checked the big seal seat there was a couple scratches from someone putting the big bearing circlip in.
I'll know for sure in the morning but I feel certain leak is fixed.
