Not quite like the time I sent THREE bikes worth of fasteners and bits, plus all my spares to be plated all at the same time, then came the time to part the water.

Actually, having done a bunch of Commandos, it's gotten a lot easier. Now, throw in a Triumph batch in there and start sorting!

I still haven't touched the pile...I don't even want to think about 3 bikes at once. :shock:

I got almost everything sorted a few days ago. Just a few bits left that I forgot to photograph - I should be able to figure out where they go. I got the spokes back from the cad coater on friday and rubbed them with fine steel wool. Got everything laced up on the front wheel this morning...now if only truing was just as easy.

Just post a picture of the parts. Makes it fun for us to try and guess the parts!

Ohhh, so that's what it take to get a head turner, ugh. Great photo's to feel the pretty puzzle. Cadmium is toxic so don't get too intimate with em.

Hey Mathew, Weren't you looking at buying a learner bike at one stage, what happened there ? did you buy something.?

AC,
Yup I'm still in the market. I've just gotten caught up with the norton and summer vacation so I've eased off my searching. But if anyone sees something let me know I'd be more than happy to look myself. Up here in Canada te riding season will end in a few months so getting a learner this season won't be a big priority. I will keep looking throughout the long cold winter though.

Swoosh,
I have a pretty good handle on some of the stuff. The unknowns will be posted eventually if I can't find a home for them... Maybe I'll just post them anyways to keep you busy and incase you haven't noticed, my thread already has a lot of pictures so I'll stick with the trend.

Hobot,
I think all of the fumes from my fiberglass sidecover repair job and dust from aluminum sanding and polishing will put me to an early death - what difference will a little kiss on my freshly coated front axle make? :mrgreen:

Well I finally figured out where all of my cad plated stuff belongs! But more importantly, after a few quick tips from you guys, my dad and I got the head assembled tonight. Minus the rockers cause it was too late to heat up the head in the oven, and my mom was home so she wouldn't be too happy with us. But I did take pictures of what we have! I'm very happy with it.

Some weird lighting in the garage made the head look a little dull, but to me it seems to be pretty shiny in person. Tomorrow we hopefully can get the rockers in place, join the top and bottom ends and have a complete engine!! That is, if everything goes as planned, which never happens with Brit iron, otherwise it wouldn't be fun.

Matt,
Put the rocker shafts in the freezer for an hour before you are ready to install into the head, it does help even when the head is warmed. (Remember flats face out)

Well I didnt have time to get the rockers in before dinner... I did get the forks together though, they look pretty good, I'm happy with them at least.

I think I'll get the rockers in tonight and if it goes quick, the barrels on the crankcase...we'll see.

Matt

AltaNorton · Aug 7, 2011

And here's the rockers that we got in place. Didn't have time for anything else though

I may have encountered another problem!! My dad and I got the barrels on a few days ago, but from what the manual says, the timing cover chain and oil pump etc. should be assembled first. This is because you need to be able to hold the crankshaft so it doesn't turn while putting the nut on the timing side end. Without thinking we put the barrels on first, is there a way we can hold the shaft while tightening the nut down so we don't need to take everything apart again??

Thanks,
Matt

Seems like it might work. Only trouble is the one I have doesn't have a torque setting and a new one with a torque setting will cost hundreds. Would putting the primary chain sprocket on and holding it from moving work? Seems like it might if I can hold it with something, I'm sure my hands won't be strong enough.

Well if it were me ... I would put the engine sprocket on; along with the primary chain in a vice. Not sure how yer gonna do this while keeping the engine secure too. (same metal vice ? :shock: ) Just might have to get creative. Or ... bite the bullet, take the barrell and pistons off, and do it the known "safe" way.

grandpaul · Aug 18, 2011

Vice-grip pliers on the primary chain (use the old one).

AltaNorton · Aug 18, 2011

I think ill put the sprocket on and 2 bolts in the puller threads and stick a piece of wood in between them to prevent the shaft from turning.

But I've ran into one, maybe two much more worrisome problems.
1. My camshaft wont turn a full 360 degrees. It rotates all the way around by hand then gets stuck on something at the same point every time. I doubt anyone has had this problem but maybe? any solutions other than pulling the barrels? **edit** the shaft now turns all the way but sticks at the same spot and doesnt feel right.

2. My second threat may be much larger. The camshaft has a lot of end play. Probably between 1/16'' & 1/8''. I personally did not assemble the crankcases, I let the machinist who inspected the crankshaft and bored the cylinders etc. put the crankcase together. All he did was put the crank and cam shafts in and put the connecting rods in place. Im wondering if he forgot the washer that goes on the drive side case cam bushing. (is there even one, I though there is...maybe not?) Anyways, he is supposed to be the best Norton guy in my area and has done numerous. Hopefully the play is supposed to be like that and he didnt screw up.

There's a very important hardened thrust washer that goes between the cam and timing case.

Ruh-roh...

I think that one is in there, It has a 90 degree bend coming off the side of it, that fits into a little hole in the case, right? I can see that one through the hole, its in there.

If your timing side cam bushing has "NO" flange then you will have 2 washers in there. The beveled one with the beveled end against the cam shoulder and the tabbed one that you speak of. It is also advisable to break the tab off cause they can break themselves off and go where they shouldn't.
Again, no flange bushing = 2 washers.
Also, the tach drive will keep the cam pulled over to the timing side against these thrust washers. I am not sure what happens when go with an electronic tach and pull the worm out.

Edit. If your bushing has a flange (later type) the tab washer is eliminated.
