Thread '1970 Amal Carbs - 930/46 & 930/47 difference?'

Aug 29, 2010

Hi, i was wondering if anyone knew what the difference was as a few sources have listed the 1970 model commando as having 930/46 & 930/47 amals, how are these different from the 930/30 &930/31?

Thanks heaps

Next up is this rear wheel. The project was finally delivered today. Looks like I’m missing a lot of components for this rear hub.

A thread you may find helpful:
Type "Front and Rear Bearing Removal(2010)" in the search bar. Post #25 has a drawing of the Rear hub assembly which I found less confusing than the Parts Catalogue exploded view to show the components.

However, that's for the cush rear hub and disc front wheel, the 1970 type in the pictures is the bolt-up rear hub.

Although I started with the rear for this I'll start with the front. Remove the lockring. Mine was really tight. So I applied some heat which did the trick. I had to use a punch but it didn't take much to loosen.

Remove the spacer and felt seal.

The single row bearing.

With a long punch you can pop out the bearing.

A lovely bearing spacer. Luckily it was just yucky.

i wouldn't go with an unknown history rear axle & there is a 1 piece axle option

Alan L said:
Hi,
im obviously missing something
What is the reason of changing to a one piece axle. Is there a significant problem with the two piece axle.
alan

The main axle can snap in the area of the thread that screws into the dummy axle.
I can not say I have had a close look but that might be to under or over tightening or the axle (non threaded) shank not entering the dummy axle as support so the exposed thread fractures over time. (maybe)
In other words if the shank is down a bore it is supported a low stress riser (unlike a thread radially)

I purchased a Don Pender rear axle from a Forum member a couple of years ago, and just now have an opportunity to install it. It didn't come with any instructions, and with everything apart, I have to admit I'm stumped. Are instructions available?, required?, or do I carry on until I have that A-Ha! moment?

the mk3 two piece axle is 17mm. If you cut the stud off the stud shaft and open it up to 17mm you can insert a one piece axle. I have used the axle from a 1983 kawasaki gpz 750. one must redeuce the length of the shaft and put threads on it for it to fit the swingarm.

Anyone have pics of the safety spring installed ? I am looking to buy one but in studying the picture on Andover Norton’s site I can’t make sense of it.
It appears to go around the pedal shaft with the crook going around the pedal arm but where does the straight tang bear against so the pedal loads the spring instead of just rotating it ? What am I missing ?

Alrighty - first step is to get this motor apart to see if it is salvageable. So far I've aquired some correct year yokes, later style forks and sliders with a norton caliper, a used complete rear hub.

Happy to keep this build thread going if you all are interested. I'm pretty sure this bike was raced back in the day. Might get lucky and find some performance parts. The paint job has Bardahl oil inlays. A sponsor?

In preparation for disassembly I think it would be a good idea to get a set of whitworth sockets and spanners as well as any special tools needed.

Any recommendations on whitworth socket/spanner sets and from which sources?

Which special tools to get from Andover Norton for engine dissasembly?

Excellent start. You got the correct yokes for that frame and properly navigated the front brake upgrade parts. You will need a hydralic master cylinder at some point to work the disc. I don't like the original stock master cylinder that has a screw on top... It leaked a few times over the years and ruined the paint job on my fuel tank every time. Eventually I got disgusted, sold the original to someone here who needed one and I bought the replacement brake lever from "Madass140" who lives and manufactures parts in the phillipines. It's got a better hydraulic ratio on the lever so the brake lever is more powerful. I use the "1/2 inch master cylinder kit" which is half way down this page... He also makes a full kit with a disc and a improved caliper if you are up for spending money on "jewelry" as well as just what you need to get on the road.

Norton Commando | tritonmotorcycleparts.com

Madass, (Don) also makes some really nice stuff which is more expensive than his brake MC Kit, which is a bargin at $150. He makes an aftermarket rear wheel that looks just like the stock wheel, but has modern cush rubber damped sprocket and a one piece "through" axle to replace the stock norton rear axle set up which had been known to occasionally break... The rear sets he makes are copies of the dunstall style ones. I have a set on my bike and they are solidly made and not cheapo looking... Anyway, look around his site...

You will need a slim 1/4"W socket and extension to remove the two upper head nuts and #1 bolt (preferably 3/8" square drive as that's more useful for working on a Commando). Slacken all head fasteners except for bolt #1 then slacken #1 (see manual) and the head should lift squarely, same when refitting the head pull it down with #1.

Am I able to use a later style center stand and kick stand for this early model frame? It was mentioned that the early model center stand and kick stands do not work very well

L.A.B. · Dec 22, 2024

You would have to drill the cradle to fit the later centre stand. Your frame would need the forward cross-member that supports the later side stand bracket.

hope everyone had a great holiday. I’m having trouble figuring out which side covers will fit my frame. Andover has a bunch of types listed for early models but searching around the forum it looks like only some side covers fit certain years.

The project came with a centrally mounted oil tank. I hear there is a hard to find side cover with a rotolock hole. Is that the kind I need? Or will these aluminum covers fit?

Those are for the Interstate.

The central oil tank models ('S' type and 1970 Roadster) had a RH access panel and fixed LH panel.

Regardless of authenticity you don’t want the early stand . There is a reason they changed it - they fail. Ask me how I know…

I’m learning. Technically my frame number is a 1970 fastback. All pictures of a 1970 fastback point to having the more square looking covers.

Are the roadster and fastback considered the same thing?
