Title: 1952 bsa plunger (broken rocker spindle)
Post by: anjimehra on 22.03. 2010 06:44
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

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  *smile*
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 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

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.

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 !

Hi A10GF

The spindle arrived today, 12 days after leaving Oslo. As you had predicted, the North Korean angle helped enormously & the parcel just whizzed thru customs !!!!!!!!!!!!!!!!!. It actually landed in Delhi from Norway,& then came on to Pune ( 1800 kms South )
Thanks a million for your generosity. Maybe some day I can reciprocate . Ive already mounted the spindle & will hopefully fire up the engine tomorrow. Shall keep you posted
Take care
Anji

Excellent, glad the part fitted fine, and glad to be of help.

The spindle came off a complete spare rockerbox, acquired from ebay US as I needed a rocker because of a chip in one of mine. So the spindle have traveled quite some distance before getting back into use.

installed the rocker shaft & took the bike for a trial run 5 weeks back. Just got on to the main road 2 km away when the clutch stopped working & the kick spring broke.Got the bike back home & opened up the gear box cover & clutch cover.
The supposedly "original" operating rod had a big hole at either end & was obviously not hardened.Got a length of En 19 & induction hardened the ends to about 50 RC. Decided to replace the friction plates too but none available here for the dry clutch. Ultimately took off the old inserts & replaced them with cork.Will now try & run the clutch without the housing so that oil can get to the cork. Keep your fingers crossed. Just awaiting the kick spring which I have given to a workshop to make
NEVER A DULL MOMENT

hi anj
i used to run a bullet tour company from delhi in the late 90's,i bet there's lots of companys now,i spent many years traveling in india,and repatriated many bikes aswell,always miss it,your not living in that ashram in puna are you ?
Title: Re: 1952 bsa plunger (broken rocker spindle)
Post by: anjimehra on 22.06. 2010 11:44
Hi Andy
Nice to hear from you. My son & I have also been running a bike tour company in India since 1995 using Enfields.I dont know if youve been to our site @ventureonwheels.in Yes theres lots of company's doing this out of Delhi, one cheaper than the other & its totally screwed up the market. We actually try & cater to the born again bikers whove come back into biking after having left it for the rat race & can now get back with a vengeance.Not that we dont encourage the younger lot too. Where do you live nowadays?
What did you call your company? We actually do the whole of India dependant on the season. Summers its Ladakh, Himachal, Uttranchal & the North East. Winters its Rajasthan, South India, Kerala etc.
I assume youve been to Pune since you mention the ashram. We stay in Koregaon Park a short walk away from the Ashram. If you ever do come to India you are most welcome to come & stay  with us & we can exchange notes. Incidentally, I rode my Super Rocket back to India from UK in 1965 & in 1964 did a trip in North Africa on the Super Rocket. We rode down through france, Spain, Gibraltar, Morocco to Marakesh & across the Northern tip of the Sahara to Algeria , Tunisia . Still have the 1961 Super Rocket which is next in line for restoration after the Flash is done ( or rather WHEN the Flash is done )
What bikes do you have? Do keep in touch & take care
Anji

Andy,

Reading your post about the near catastrophic tour, I was curous to know what "Madaan Motors" was about. I was amused to find this link:
www.madaanmotorsthief.com . It's an amusing story (to me, at least), and I wonder if it doesn't explain your last shipment that wasn't sent.

Yes, I know Arun from Madaan Motors for many years.He was also tied up with some German company called I think Asia Bike tours ???
but for the past 2 years this has also slowed down.He is currently concentrating on exporting Enfields & parts for classic bikes.How come he held up your shipment?
Sorry to hear about your bad experience with him & also the floods. Where did you get stuck.Was it somewhere near Wangtu, when the Chinese let out the flood waters at Parichuu in Tibet into the Sutlej.
