Hello to all,
Briefly, I bought a Mk3 1977 Interstate. (low miles, engine rebuilt but a bit tatty, usual story)
I found the steering head bearings faulty and the front brakes bad.
Removed seat and tank, the frames bent. Had the frame straightened.
Gear box was leaking from the kick start shaft.
So, what else is not done properley??????
I decided to do a complete rebuild and learn about Nortons along the way and be sure to the condition and fit of everything.
Luckily I caught the new cam had started to "gal" and was very soft and the lobes weren't ground flat with the shaft.
1 x "D" rod, a new rod was available at a good price.
Crank balanced, Head and cylinder surfaced, new +20th pistons, valves, etc.
Replace the bearings in the gearbox, seals, etc.
Replate all the rusty nuts and bolts, and new isos (which were stuffed) etc,etc,
So I'm onto the best bit, putting it back together. And the reason for this topic.
There doesn't seem to be enough spacers and bolts, all the major ones that hold the large things such as engine and gearbox are there. But some of the small items like the spacers for the top shock mounts and the weird brackets that hold the electrics have (according to the parts manual) spacers as well.
Is there somewhere where the size of these spacers and bolts can be viewed? then I can make them.
I have the part numbers for all these, but that would be expensive to buy and slow down the rebuild.
I'm pretty sure everything that went to the platters, came back from the platters. Maybe these bits weren't there when I pulled it apart? Considering some of the shoddy work I've found this is likley.
I do have way more washers than what I think is needed, maybe these were used as spacers?
Regards Graeme.
