51-53 Maintenance Manual

Forums

Hi,

I have a LS Featherbed manx, the engine was recently professionally rebuilt but rather than send it away or get someone to look at it each time anything needs doing I'd much rather do it myself. In order to do so I'd like to learn a lot more first.

I've seen on ebay and a couple of other places that there is a maintenance manual for the inter/manx up to 53/51 respectively. Does anyone know of one which would cover my bike, is there a library section or anything anywhere I can download one? Would this one do as the engine is still a LS and they didn't change to the SS until 53/54. I'm assuming this manual just doens't cover mine due to the frame change.

Regards

David

Assuming its asingle cam motor there is littledifference in themodel years maintenance manual. What isimportant is that youtreat your motor as an individual unit. Theprinciples within themanual arecorrect but the settings you have areunique to the wayyour motor isset up. Ifyou are unsure of component builditis alwayswise tomeasure everythingbefore you pull it apart, not rely on whatisin the book.

I run a 37long stokeInter MSand lostasmooth running easy starterby reverting to standard settings and took a wholeseason togetback the bikeI had. Overtimethere may bemany different componentsaddedand variationsinmachining or finish willalter individual machines,( that's whysome are quickerthan others smiley).

See the book asaguide butget toknowYOUR motor. They aresimpleunitsbut sensitivetochange; andare infinitely changeable.And record everything you do; those notescome in handy for you and for others in thefuture.

Mymachinehasamixtureofcams, valves, timing, carb settings that donot conform to anyparticularmodel year but it goes well, starts well and bringsmuch enjoyment. It its the result of manyyearstweaking, adapting through the yearsto changes infuels, oils, type of use and probablyage....

Have fun smiley

The attachments show a couple of books which cover the Manx Engines and are worth getting copies of. E.M. Franks was a well respected member of the Norton Factroy engineering team and had a hand in the design of pre- 1950 engines. Much of the contents of his book is duplicated in the very hard to find P.L. Garrat Maintenance Manual.

The two side by side books have essentially identical contents. The Red and White cover book being an earlier version. These also cover both Manx Model 30 & 40 engines.

Hi,

Thats what I'm trying to do, get to know it, I'd like to be able to do a lot of work to it myself. I've built the whole bike with the exception of the engine which had a full rebuild by Andy Savage. The guy is a legend and did a brilliant job and I bug him for help and advice more than I should :)

I've tried to attach a pic of her, she's semi finished there, now it's rideable but needs lots of fettling and the odd little part here and there. Currently I'm trying to sort out the fuelling...

Ron Gardner is just sending me out a new float chamber because neither of my 504's are holding a steady fuel level so the bike is running very very rich. They're mounted on the frame with the proper mount but if I set the level (to the inner circle on the GP2 carb) while stationary as soon as the bike is running it goes up and will fluctuate by about half an inch. If I set it while running then every so often it will drop again back to the stationary level obviously leaning it out. I've tried both rubber tipped needles and standard ali ones. both floats have had machining done to them to square off the needle seats and get rid of any wear but no joy.

I'd just like to learn more about it so I can do everything myself as at the moment my knowledge is very limited. Any idea where I should start to get hold of these books, it's not like I can just do a search on Amazon :)

Who'd have thought it, the "Norton Motorcycles 1928-1955" WAS on Amazon :)

AND....

Ebay for the EM Franks one, thanks very much :)

There is also the P.L.Garrat book that goes up to 1963, and this covers the OHC singles and Norton also produced a handbook for the camshaft singles back in the 1950's.

I will check thedate on my Nortonmanualsif youarelooking forfurther reading butwhat you are afterwill notbe foundthere. I don't knowmuch about theGP carb ordualfloat (Notacommonset upfora solo)butI'm sure there arearticles around that will guideyou in theright direction. What part of theworld are you in?

Interestinglooking machine, what'syour intention with it. Is thewelded up bolt up rear end something it came with orareyouparticularaboutseat height? My manual is up to53 Inter, 51 Manx.

Not a good assumption - the first dohc Manx was 1949. The LS featherbed Manx engine is a complicated beast, and parts for it are hard to find. It's neither close to Inter nor to SS Manx.

I tried for many years to locate a copy of PL Garratt's book, and finally scored a loan of one, and photocopied it. It was an interloan from New Zealand's National Library....

Well I have both books now anyway and if nothing else theyâll increase my knowledge about the Norton Singles.

The bike came with nothing, it wasnât a bike when I got itâ?..

My father bought a LS Manx engine when he was very young (16) because he had always wanted one, he then lugged it around every house move etc since while slowly gathering parts for it. When he died in July 2014 I thought I would start and finish the project he never got chance to do, so with very limited knowledge I set out to put it together.

I found the engine in quite a poor state in a cupboard in his workshop, the frame under some crap in the corner of his shed. Front hub stacked with a load of other hubs/wheels. You get the ideaâ?. I decided the Frame was the one he had got for it due to it being close in years (54 Dommie bolt up, 51 LS Manx engine), the front hub is the wrong year though as are lots of the parts on the bike. EG it has a cottonreal Dominator rear hub.

Lots of parts are home made through my rudimentary lathe/metal skills and lots are off of ebay. I made the choice though to get someone who knows what theyâre doing to do the engine, hence why Andy Savage did it. Now though Iâd like to know more about the engine too hence this request.

Iâve already jumped through all the hoops for DVLA etc so itâs road registered now and I was planning on showing it in public for the first time at the Calne Bike show at the end of July as I live near. Iâm quite desperately trying to get it to fuel close to correctly though, itâs way too rich at present. New Gardner float is on now though to replace my leaky 504 so will soon know if itâs sorted it.

I donât know if the bike is how he would have wanted it, but for the most part itâs a Manx and Iâm hoping good enough to join Manx startups/parades etc. Weâre going to the Manx GP/Classic TT in August to spread his ashes and taking the Manx and his old Commando which my brother has been restoring.

Paul, how much would you need in order to make me a copy of the book if you have one? I was thinking about scanning the 2 I have in and mailing to the club, but I donât know how far back copyright etc will go, anyone know when it comes to books? Could be nice to increase the size of the digital library we have.

I made a pair of photocopies, not sure where the second is at the moment. The best plan is probably to send a copy to the Club Library, for scanning so that we can all benefit from it. My computer is old and has little hard drive space left, so I don't think I can do it until I have a newer one.

Paul, if you feel like copying it again I'm hapy to send funds so you can do it at a post office or something, I can scan and send it in then if you just post the copy. If not do you have the details of the loan you got and know off hand if it' still possible?

Get in contact with Barry Strickland, the NOC Camshaft Singles man. He should be able to help with regard to finding a copy of the Garratt manual.

Although I can not see much difference between its Manx contents and those of the other books mentioned as worth a read.
