Has anyone any experience of drilling the swing arm pin out? That seems to be the next option.

What diameter bit is required?

The pivot spindle is 7/8" diameter. It should have a 1/2 UNF internal thread? So personally I would try using a draw bolt with a suitable length of thick walled spacer tube and washers to draw out the spindle whilst the assembly (especially the central tube) was heated with a welding torch. The only part likely to be damaged by the heat will be the spindle-which is going to be scrap anyway.

Will oversized bushes be required and can these be bought off the shelf?


If you manage to remove the spindle without damaging the bore of the cradle tube then I see no reason why you will need an oversize spindle and/or bushes, as there are no bushes in the cradle tube, however oversize spindles (+.005"/+.010") are available.

What should I expect to pay to Powder Coat a frame? I have had a few quotes of around 1000 UK Pounds to spray the frame and ancillarry components like the swing arm.

HOW MUCH!!!!! That's daylight robbery. I just phoned my local specialist powder coaters (http://www.aerocoat.net/index.htm) they said a frame, swinging arm plus a few other odd parts in black powder coat would cost around £150 and not likely to be more than £200.
 
Whoa!! £1000 is on the same level as Corporate or Government theft.
I've no experiance with the Norton yet. My old Bonnie which has a Bazillion
more pieces/parts to strip and coat, ran me about $475, or in the neighborhood
of about £250.
 
What a great thread Mark!
I've just read it from start to finish and I'm now hooked :)
I can relate to some of your experiences in Nigeria, I've never been there but have spent time in Angola, Gabon and until December last year I had a great trips to the Ivory Coast once a month, that's all gone to sh*t now because of the presidential election results. This year is looking like it will be Senegal.

Good luck with the Commando, I look forward to the next installment.

UGH, I've run into TWO-2 fused in place spindles d/t someone trying to use grease instead of oil w/o modifying to allow grease to get to bushes and another one someone let the bike sit for years w/o constantly topping off with oil couple times a year. HORRIFIC efforts on my first encounter, using truck shock absorber bolts and strong puller and sledge hammer and drift, used so hard it broke hand bones and drift had to be ground down many times from the mushrooming ends. When finally free after a week of trauma it left the swing arm so tweaked, expert famous frame straigthener could not get a spindle to ever pass through again.

Next time I ran into fussed spindle, I tried the shock bolt puller and sledge hammer a few minutes to realize no give at all so wisely gave up, gas torch cut off the swing arm and took cradle to Bulldozer shop whose press PSI topped 22,000 to even start motion then never got below 16,000 PSI till spindle popped free. That's 11 to 8 tons pressure to remind me to convert all my Cdos to real grease zerks for the next owners salvation if my bikes sit for years w/o me.

I fear you have wasted time and effort and even if successful swing arm and cradle can be distorted by the tons of force required and no way to fully back up the cradle to such loads w/o special machined heavy duty jib that'd cost as much as a running Cod. Drilling out may work but expect to pay a lot for the many bits to replace as the spindle surface is very hard. Go ahead try to have spindle pressed out, may save the cradle or swing arm but may learn the hard way too.

I advise to cut your loses and get new cradle and swing arm. Maye upgrade to alloy cradle and RGM swing arm for about $1000 usa total. Then convert to no mess low low maintenance zerks.
 
I had similar problems with mine, the press didnt touch it at all and the fact its kind of awkward to hold. What did work was oxy-acetelyne and a big hammer, the only down side of this was putting a couple of marks in the o ring groove when the hammer missed but I have already drilled it for grease nipples and cut some grooves in the bushes for the grease.
 
Yeah man Cheesy, convert to real functional greaser and save broken parts and hearts of owners after we are gone.
 
I've got a 750 swingarm, bushings, spindle and cradle you can have for the shipping to Blighty if you can't rescue the original or find replacements at a reasonable price--I'm in the Chicago area. As a kid I ran a '62 650SS all over Nigeria and Biafra--at last report that bike is still flushing the fauna in Francophone Africa.

Have faith in the Forum, brother, every body wants to help. When you get around to Ignition, please look into " Tri spark ", www.trispark.com.au made right here in Adelaide S.A. All reports are good, and easy to install.
 
Thanks for your offer Tim, and I just might take you up on this as I was hoping to have all the Powder Coating done on this trip, and this would a major hassle for me if I could not send all the PC items to be coated at the same time.
However before I commit, can I that the Swing arm and cradle are identical for the 750 and my late 850 mk2

Looking forward to your thoughts and pls PM me for price of carriage and items, as if identical I will take them. Will send you payment by Paypal as soon as I get home on Tuesday/ Wednesday, and will reply your PM. Will be much less painful than having to pay out my losing bet of 5 pounds to my 11 year old son that Wales would win the rugby... and they lost, to England of all countries- Can you imagine?? Still it will be great to be back to the drizzle and grey days at home :D .

Not completely identical, as the Mk2 swinging arm is stiffer.

Did you try what I suggested? As I have yet to encounter any rusted parts that wouldn't separate if enough heat was applied.
 
Yes We tried and Managed to bend the engine cradle, so I am taking the whole assembly home and cutting off the swing arm, which for the moment appears undamaged. I might be able to re-use the swing arm but the engine cradle is toast. :( Amazing the staying power of a rusted up spindle.
 
UHG, you are the 3rd case I now know about finding a Fussed in Place spindle.
As I said the first one like this I extracted, ended up with broken skin and hand bones through heavy duty leather line men gloves you can pick up almost molten metal with, missing aim d/t the full power swings so many times I got miss-coordinated mid swing for bloody murder screams, till settle down enough to carry on and break more bones and skin and wear out both the hardened drift and face of sledge hammer. I also had serious puller on I'd almost stripped threads on, nipping up between a few hammering attempts, on and on and on for about a week in evenings and week ends. I won that one but it ruined swing arm. Next time I put most extreme impacts and pulling and high heat on and didn't get a bit of action, I got out my torch and cut off swing arm to at least try to save the cradle and did but almost lost cradle too, d/t the BullDozer size press distoring it to free spindle.

Nigeria continues to have horrible news stories coming out almost daily. Too sad how they suffer there, some their own doing but a lot not their fault too.
 
Yes hobot you are right as I well know, Nigeria is a strange place, often violent and an assault on the senses, yet surveys show Nigerians are the happiest people on earth- beats me, but what I can say is now I am used to it, the madness becomes 'normal' and you just learn to take it in your stride. TBH I quite enjoy my short stints there, and will miss not going back now for a few months- it gets addictive.

This is a picture I got on the way to the airport of a Policeman on a motorcycle taxi, going to or from work.... cool huh with a beer in one hand and cigarette in the other. Things you see in this place you really couldnt make up.

Suicidal Motorcycle taxis called Okadas are the source of endless amusement in traffic jams here. I have often thought of starting up a website just for pictures of the incredible things ( and scrapes) they get themselves into.

Anyway, I am so glad to be home (to lovely weather for a change) after a trying flight back with the frame of the Norton, and 2 bags of parts.

At Lagos airport just about every man and his dog wanted to see the frame and authorise its removal from the country- all for a 'price' of course ( In Lagos it is called 'something for the weekend'- in UK its called extortion). The security first wanted their cut, then customs got very excited about 'exporting' a vehicle ( that cost a 500N /6USD) 'payment' then the drug agency wanted it checked ( another small 'fee') and then the BA luggage handlers would not touch it as they were sure it would not fit into the aircraft ( A Boeing 747 of all things). They need a fee of 2500N (15USD) to 'check' it would fit.
It was so funny being escorted Airside to literally check the frame would fit, and seeing the security guard with his feet on the desk (without shoes or socks on). He obviously did not get many non airside authorised visitors and did not have a pen or ledger to write my name and passport number, so borrowed my pen and wrote my details on the back of the newspaper he had been reading.
After a few minutes, the baggage handlers must have stretched the plane because they came back duly satisfied that they had somehow gotten the frame in the hold, and made it seem like it was them that had done me the favour.
I did not feel inclined by this stage (2 and half hours later) to tell them it was to be loaded into the baggage containers. Sometimes things here are done pointlessly just to get a 'fee'.
Next time I saw the frame was by the luggage Carousel in Heathrow airport, and putting it on my baggage trolley with 40kg of Norton bits in 2 bags was one of the best moments of this saga so far, as now I can properly start to do some restoration works.
I wheeled it through UK customs, who I was sure were going to take a very keen interest in it and they didnt bat an eyelid. I couldnt believe that and walzted through to my pickup on a foggy chilly morning without any more palaver.

Now I just need to get this swingarm cut off and then start arranging all components to get them ready for powder coating.
I have read the Oldbritts article on powdercoating and have a couple of questions:

1. Are the yokes ( fork 'trees I think in US speak) meant to be black? Mine are and I am not sure if they have been overpainted by the PO, as most owners on this forum seem to PC them silver.
2. If they are meantto be silver, is there a reference colour silver?
3. If they are meant to be black, is the black same colour as the frame?
4. What colour black is the closest to Norton Frame Black and is it gloss shine or a satin type shine. My frame is so sun faded I really cannot tell.
Thanks Guys

They would most likely have been silver originally, but I couldn't tell you exactly what shade of silver it is.


As you have now 'imported' the bike in a rather unusual way, it could be worth contacting the DVLA to see how you stand as far as registering it is concerned? As I would expect them to want to see some form of importation documentation when you eventually get around to registering it in the UK?

I am also wondering if the bike is liable for any Customs duty even though it has been imported in a dismantled condition?
 
I expect it should have originally been 'Rally Silver". I believe all the British manufacturer's used this color for
silver painted parts. This color however, has become astoundingly difficult to perfectly match. Don't ask me why.
Someone on this board had their's powdercoated in the chrome color. It's not really Chrome but it looks great
and the match is about as close as I've seen.
 
Mark,
I did my frame and parts in 'liquid black', the yoke parts including the front mudguard bridge in 'Chrome'. Usually the yoke parts were silver in colour. I thought the chrome colour turned out quite a nice silver colour, not chrome looking at all. The OB site is real nice to figure out where to mask, but let me tell you, after the shop blasted off all the old stuff and I went back in to put all those nuts, bolts and washers on for masking, the guy said no, no. The grease from the new nuts, bolts and washers would bleed all over the frame in the oven and mess up the coating. He showed me that he had all sizes of plastic paste on circles and larger pieces that could be cut with scissors to any shape desired and just stuck on where desired. So I just masked all the places I wanted with the plastic circles. They should have plugs for the threaded parts too. Turned out just fine. You may want to talk to your powder coater before you get too involved with him to see that he can accommodate what you want to do. I found most places just wanted to do it and were not worried about the masking part, they insisted they knew what they were doing since they had done tons of HD M/C so they were experts. I'm sure if they had done it, I would have spent a month cleaning off powder coat from places I didn't want it.

As far as the original colours, there are many opinions. I just used what I liked and looked somewhat original.

Mark, you must be a wealthy Commando brain rot case. I can respect that but sure glad it ain't me with your flavor of crazy. Addicted to close calls and dodging danger with reflex wits is right up my alley but not the league and scale you present. My actions in you shoes after evaluating my Commando discovery would be find a prominent tree and hoist it up then start from scratch in new home.

I like the satin silver yokes DogT. Good point about masking the thick soft powered coat as known issue to crush down and loosen fasteners and screw with grounds.

Steve,
Now you've gone to the extreme. We have plenty of yokels here in VA that keep refrigerators, sofas, axles, chained dogs, outhouses, tyres, recliners, the wallpaper is on the outside of the house, anything that doesn't work anymore in the front yard, but M/C hanging from the trees, that takes the cake.

I always enjoyed driving in WV to see the ravines full of junk too.

What a country.

Makes as much sense as commutes in Nigeria. There is a pair of "shoe" trees outside Eureka Springs here, full of about everything people once put on feet. Silly as can be but neat up lift to pull under and take in.

I've a good 750 cradle if none found in the country of origin. Found alloy one for Peel instead.
