Ok on the model A10 with the left hand threaded axel (front wheel) how are you supposed to remove the LHS bearing , the one opposite the brake drum

looking at it it has notches in the hub (inside where the spokes go) so i figured it must screw out .......i bashed it with a drift (punch) in both directions and it showed no intension of moving .......ive looked for an assembly drawing on google but cant find one

any ideas? ........like is it ACTUALY threaded or not?

the brg on that side feels ok but i was able to replace the bad one on the drum side but i know not having done both will irritate me so intend doing the other when i can .......the wheel has to come off again as some comedian has not fitted the brake side threaded retainer so will need to make and fit one just for peace of mind

You need the service sheets, they are around as pdf's.

There are split pins that stop the rings unscrewing. parts list shows them.

I made a tool to fit into the notches. Also the A10 Forum is a useful source of information, https://www.a7a10.net/forum/index.php

Cool got it thanks guys .........figured it was a screw in retainer ....so yeah i will be more "persuasive" of it when i take the wheel off again........didnt see a spit pin but will look again ......like if the guy before me didnt even re fit the lock ring i guess the split pin would have been left out as well

is the one im talking about (rhs) a left or right hand thread?

does anyone have a comment to my question "is the one im talking about (rhs) a left or right hand thread?
"
I know i have a parts book somewhere but cant find it i am aware of service sheets and probably dont need to be told about them over several threads thanks

besides which those links dont work....i thought the point of a forum was to help each other out by answering questions not just being dismissive , but im strange like that

MY question remains ........is the LHS (opposite brake front wheel ) bearing retainer a LH or RH thread ? thanks

I think we need more details, e.g. what year is your bike, full or half width brake, 7" or 8" brake, plunger suspension etc.

Without any of these facts its going to be hard for anyone to give advise.

The links work for me, if its a full width hub the LHS does not have a bearing retainer it has a dust seal which prizes out.
The RHS retainer is a left hand thread.

I think you’ve answered your own question although your link didn’t work.

If you had read down from the image you would have seen the relevant part numbers, one stating left hand (67-5561 brake plate side) and the other stating right hand (67-5562 the other side).


Now let’s all have a beer beerchug

Does it look like this pic which is the 8" half width type as used on BSA 1949-63 A, B, M models?

[Linked Image from draganfly.co.uk]

This diagram shows the spindle 67-5566 which is 9/16 in X 20 TPI left-hand thread as mentioned in your initial post, more info Here

The bearing retaining ring is part 67-5561 and in all the google searches I've done for this part, there is no mention of it being a left hand thread, although its intended for the left hand wheel side so maybe thats where the confusion comes from.

My guess is that its a right hand thread so I would be trying to undo it that way.

yes that is the one Gunner .......of course they have drawn it mirror image just to do your head in more .....note the brake is drawn on the left hand side of the page

67-5561 is the one im talking about ........you recon that would be the normal RH thread ? i will give it some less gentle assistance and see if i can persuade it to move

I have the half width front wheel on the 57 A10. The retainer is LHT. Also the Haynes book says LH, for what its worth.
