1952 bsa plunger (broken rocker spindle)

[anjimehra]

Fired up the bike & evrything ran fine for the first 3 days. Was feeling really chuffed, but alas tragedy struck. Found the exhaust rocker shaft doing a jig of its own with oil spewing out of the banjo. Stopped engine whipped off the rocker box & found a broken Exhaust rocker shaft. Examination of the sheared face showed it was an old break with the shaft attached by only 3 mm of metal which now failed. Didnt notice this as the shaft looked intact & Ive never had one fail on me before.
Does anyone know where I can source one from? Push comes to a shove, I can make one here, but would like to avoid the hassle

Mark of BOA has listed two on his homepage:

http://www.vintage-motorcycle.com/index.php?language=de&site=4&pid=11&id=5865&gesucht=true&suche=normal&suchstring=rocker%20bsa

http://www.vintage-motorcycle.com/index.php?language=de&site=4&pid=11&id=5870&gesucht=true&suche=normal&suchstring=rocker%20bsa

Unfortunately there is no more description about whether they are A10, but they look like they are to me.
You can drop Mark an email, he has many used spares that are not on the homepage. Maybe he will have something for you.

Cheers, Markus

Gday Anji, I have had exactly the same happen to me about 25years ago. I couldnt work out how the shaft would brake, but it did. Maybe it droped at some stage and cracked or it was from an engine that blow up from racing or something. It was a hotted up engine it had very high compression pistons, ported out big valve head and 357 cam.
I rode it for a little while with a broken shaft because it was my only transport at the time. I hadnt pulled the shaft out at that stage so I didnt know what was wrong. It leaked oil quite a bit but I had to get to work etc. I didnt have any spares at all then it was my first BSA.
You see rocker boxes on ebay all the time with rockers and shafts for not alot of money. The shaft doesnt need to be new one a second hand one is fine.
You're in India are you? If you dont see one on ebay soon let me know I have plenty of them. I even have new ones still in wax but I wont sell them. cheers Terry

Terry, I might have to take you up on your offer of a used spindle. How much would it cost & what would be the postage costs to India?

Thanks guys & take care

Hello Anji!

I just realized that it is the rocker SHAFT you need, I thought it was one of the rockers that broke. I should take a bit more time reading the posts prior to replying  
Sorry!

Nevertheless, Mark has one listed:
http://www.vintage-motorcycle.com/index.php?language=de&site=4&pid=11&id=403&gesucht=true&suche=normal&suchstring=rocker%20spindle

Not particularly cheap, but as manufacturing one includes case hardening and grinding to size, probably the easier way. AFAIK the inlet and exh. shafts are identical.

Cheers, Markus

Hi Marcus

Hi A10GF

Thanks a million for the offer. Iam currently trying to procure one locally, failing which I shall take you up on the offer.
By the way, I see you are from Norway.I used to visit Norway with my classmate, who was Norwegian, every Christmas from 1962 to 1964. His father was a doctor in some place called Nes Hedmark ?? I remember we used to drive across this frozen lake to reach his home. Have you been there? Temps wer minus 30 if I remember correctly, or atleast it felt so
This Norwegian friend, Yan Hvidsten, used to ride a Road Rocket & I had a Super Rocket which I still have.
Take care

Hi Terryck
Thanks once again. I have asked my daughter in the UK to try & get this. The only difference I can see on these shafts is that they dont have the lubricating groove along the length of the shaft. Attaching a photo om broken shaft
Take care

Hi A10 GF
Thanks for the offer. How much would you charge & what would be the postage to India?
Take care

[a10gf]

If you need it, you can have it for free incl shipping. The shafts on the srm and other sites, surely have the oil groove, maybe only not showing on the photo ? Read you have been in Norway, and yes it's cold in winter, inland, along the coast here much warmer. Been in Hedmark, just driving thru http://no.wikipedia.org/wiki/Nes_(Hedmark). And I've been traveling in India in my younger days, Jaipur, Bombay, Delhi, Calcutta and more.

Hi A10 GF
Iam going to take you up on your kind offer, as Iam still unable to lay my hands on one here.

When were you in India last. Why dont you get a bunch of your biker friends & come & do a biking trip here with us.Check the web site at www.ventureonwheels.in. If you like hardcore off roading we can take you up to 5600 meters in the high Himalayas on Enfield 500's
Thanks & take care
Anji

[a10gf]

Will get it in the post (edited out your address from public view, better with PM or email).
Will be back with more answer. e

[anjimehra]

Thanks. Just one request. when posting just add that it is a used ,old spindle. This will reduce the hassles with customs at this end.
Take care & thanks
Anji

[a10gf]

Sent it today, registered post, hope it will arrive within decent time. As for a new tour to India, would love to, but health is not the best regarding long travels, and the same with my motorcycle mates ! Wish I was 18 again... at that age we did nor realize how lucky we were !

Regards

[anjimehra]

Thanks A10GF. Much obliged. Now eagerly awaiting the arrival of the parcel.Will keep you posted
I dont think one ever goes over 18 when ones a biker. Try a trip here. Iam sure it will rejuvenate you.
When were you in India ?
Take care
Anji

Hi A10 GF
Does the rocker spindle parcel have a tracking no? That way I could keep tabs on it & see if its stuck up in customs
Thanks
Anji
