Hi Bruce, There are also o-rings fitted behind those 2 screws that hold the shift axels. you can just screw the bolts out, pry the o-rings out and better fit new ones. Here (Netherlands) metric land we fit metric ones that are just a tiny bit tighter than the Original ones so no more leaking from there. On the kick start axle can also use an X ring, gives better oil tight result.You are very Lucky with the condition inside, after all that water, unbelevable.Nice job, succes.Gerleen de Jong.
Hi Bruce you had the right idea with the heating of the case here in England we put the case in the oven to get it really hot and the bearing will fall out by its self, to replace the bearing heat the case up in the oven put the new bearing in a freezer to get it cold when you can smell the oil from the casing take it out the oven and the bearing will drop right in. By the way it does stink the kitchen out.
lol thats right but the case does need to be very hot for the bearing to come out and go back in.Its got to be a tight fit to stay in place and not to stress the case. I did have the lay shaft bearing go soon after I bought my Commando nearly 40 years ago it started with the kick start twitching and then it going down by its self.and the shaft went through the casing scrap one gear box luckily it was under warranty at the time and had it replaced free off charge. Glad you have used my idea with the LEDs in the clocks it works really well in mine .best of luck with the rebuild Dave
I'm just looking for some thin rubber material to make one more gasket for the speedo and than I will put it together and do a final video with the LED lighting. Thank you.
Hi Bruce have just been talking to a mate of mine about getting bearings out of cases what he does is put the case in one of those roasting bags that way it does not stink the kitchen out handy tip that. I forgot to say last time about putting the case in the oven get the oven hot first and then put the case in, it will heat up quicker .
Thank you for all the advice. My gas barbecue is beside my garage so I think I will use that to heat up the case. But I probably won't have the parts in for 2 weeks from Norvil in England.
You're scaring me, Bruce. I once bought a Quaife 5-speed from a guy. It had gears hardened by the same guy who did Axtell's engine and gearbox internals. I didn't have any written info so I left it assembled. Turns out the guy I bought it from had put a circlip in backwards - first time I shifted into second gear, the circlip popped off and engaged two gears at the time. It pushed the layshaft bearing straight out the back of the case. That was a long, bad, mad drive from Ontario (CA) raceway back to Duarte! Luckily, I was working for the Norton distributor in California and I was able to get my hands on a porous-casting warranty return for cheap. I sealed up the leaky places and it's worked fine for 40 years. But there's no way I'm going to run it another mile without putting a roller bearing in it. I've seen what a bad layshaft bearing can do.
always use a genuine norton sleeve gear seal.....any others will fail.....i learned the hard way LOL....mag wheel cleaner does a good job cleaning the box .......iam assembling mine this weekend
don't use as a slide hammer, turn the slide the other way around and tighten a nut up against it to draw out. also, put in oven to get box evenly heated.
Wow...bit of a struggle there...glad it came out. Could you have placed a steel or solid wooden plate across the casing and had the threaded rod through a hole, then hold the rod from rotating while turning a nut down the rod against the plate to create a puller effect?
Yes, I didn't think about that, but I thought it would just pop out with a little heat and slide hammer. Everyone says It will just fall out with heat, no way that was going to fall out. It was in there good.
Hot gun to bloody low slow. Boil the main case in water, when it's hot enough the main ball race and layshaft bearing should fall out. You may need to tap the case on a block of soft timber. Whats wrong here. You tube can't edit without going nuts!!!!!!!!!!!!!!!!!!!!!!!

Thank you very much for the advice. I do have a metric set of O-rings. I will try to match them up. Canada is Metric as well. Thanks again. Cheers!!

I think you mean when my wife begins to smell the oil burning in her oven than she can begin bat my head right in!!! LOL

Yes, I was told early on from the Norton's Owners Group to make sure I replace that lay bearing.
what is the mainsaft bearing size?
I don't know off hand, I have an old one I can measure if you still need the size.
always use a genuine norton sleeve gear seal.....any others will fail.....i learned the hard way LOL....mag wheel cleaner does a good job cleaning the box .......iam assembling mine this weekend
Thanks Bill. I hope to get mine done this week end, but I keep getting called away. Very busy with other people crap. thx for watching.

Just heat it in the oven to 100-150° C, when you come back most often the bearing is on the bottom of the oven, if not, shock it on a piece of wood.
You must have missed my video where I tried that and much more. That baby was stuck good.

Motor Oil & Beer Why not hit it from behind now its welded?
My kind of guy.

clean the case up and put it in an oven @150deg c....while mums out shopping or something this way the case heats up evenly and it will drop out
Thx too late now and I did give that a try but must not have got it hot enough.
also, hit the bearing with freeze spray.
A blow lamp and bang it on the bench, plop
