Title: Battery carrier position ? oil tank bracket

Battery carrier position ? oil tank bracket

I am starting to put right a dog of a GF and have loads to do. As you can see from the pictures it was painted black over silver with oil tank etc still in place *eek*. As I work on this bike the more bodges I find. Anyway can anyone tell if the battery carrier is in the correct position? I am missing the oil tank fixings (was held on with cable ties, different thread) and if someone has a picture or two with the oil tank either on or off showing the position of the battery tray and the oil tank mounting bracket, I would be most grateful.

Regards

Nigel

Nigel,

Your battery carrier mounting lugs attached to the frame look about right.

I don't have a battery tray pic but here's some pics of the the oil tank fixing bracket and oil tank both on and off the frame .

Scotty,

Could you photograph the bracket flat for me perhaps on a piece of paper with a scale on. I found some steel plate in the work shop and I will see if I can make one. I will use the picture as a template.


Thanks Nigel

PS also sent you a mail.

Hi Nigel, Scotty
I do not think the photo is showing the correct way to assemble the mounting???
The rubber bush should sit inside the cup washer
There should be a steel tube that goes over the T bolt holding the washer with the cutaway up against the oiltank loops
this steel tube goes through the rubber tube and then a large OD washer pushes the rubber into the cup and the nut washer tightens against the end of the tube
This provides a rubber in compression mounting for the tank
Every BSA I get to work on has this assembly put together incorrectly *eek*

Attached is a scan from the parts book that shows the correct sequence of assembly

John,
I stand corrected (said the man in the orthopedic shoes)...Your absolutely right...the assembly does look a bit odd doesn't it.
thanks for the heads up.

I'm currently out at sea for a week with no access to bsa bits but I will gladly scribble something down for you re: the oil mounting bracket upon my return to dry land.

Nigel

it's a bit of an odd thingy but here's some measurements on the photo

I should add that the bracket material is 3.5mm in thickness and 6.3mm thick where the mounting bolts thread in (looks like a couple of washers brazed there to get the depth for the captive thread)

i also added a pic of the bracket when it was removed from the bike years ago with a more correct looking mounting thingy

Just in case you just wanted to buy one, here it is at British Only Austria.

Guys,

I really do appreciate the help on this. Every thing on this A10 seems to be either knackered or tighten up with a chisel *rant*. I had a good mind to just get rid of it but I hate to see things like this in circulation a bit like a homeless dog with sad eyes staring at you. I will just have to spend the next few years and loads of money sorting it out. Scotty thanks for the detailed picture, I will print it out and have a session in the work shop (once I have finished the bathroom).

Hi!

I?m afraid your battery carrier does have a problem! It seems to have been cut down/lowered presumably to get a larger battery or other electrical gear in.

(http://I blagged this photo from another thread on the forum (apologies to the owner) as information for my own rebuild but by comparing the two carriers you can clearly see the phantom hacksaw bandit has been at work again on your bike.)

What year is your bike? The earlier type of battery carrier is still available, see:

There is also a later type for post 59 (?) models:I hope this is useful

Hello Martin,

Thanks for the info and pictures. Yuup the bottom mounting holes have been chopped off - O well perhaps I can at least fit a bigger battery! (1961 GF - well was once upon a time!)
