Hi All
So I am on with rebuilding the front forks on my 1952 A10 Plunger, stripped forks down so could have the sliders powder coated, bought some new stations, bushes, seals and seal holders
Now to reassemble, bushes fitted to stations -sweet, stations and bushes into sliders - sweet, circlips on - not so sweet GRRRRRRR - is there and easy way to do this or is it just brut force
Cheers
-
know the feeling what i did was to make a tool out of a wooden clothes peg which is tapered, get one end of the circlip in then cut the one half of the clothes peg so it is a tight fit and has to be tapped into place and it can't come out then it can be eased in with some small screwdrivers, or you need a mate to jam a screwdriver in place so one end can't come out.
-
OH yes lots of fun fitting the circlips.
Make sure the bush is not overshimed, that renders the job impossible.
I'd try Rocker21s mothod sounds like it could work, myself I've found it annoyingly difficult - then for no apparent reason the damn things just goes in *pull hair out*

I took 2 sacrificial flat screwdrivers and, using the bench grinder, ground a hook shape into them.
I find it helps keeping the one side of the ring located while buggering around with the rest of it.
Beer , I find, helps to

One other thing to remember...don't line up the ends of the circlip with the slot in the leg as that can make the circlip difficult to remove. To have the end about 8 mm from the slot works for me. Then you can lever them out by getting a screwdriver (or ground to shape nail) behind the circlip end, where it bridges the slot.
I have not found fitting the circlip hard but getting them out can be a battle *work* *pull hair out*

Thanks for the advise all, I guess these little "fun" bits are all part of the pleasures of rebuilding !!!!!
-
When you've mastered the fork circlips you'll have no trouble fitting the rocker cover and pushrods.
As you say, all part of the fun!
-
On the mid '60s A65s etc., the circlip was done away with and a crushable spacer 42-5134 was used. It was introduced to do away with the shimming often needed under the circlip to stop the upper bush clacking up and down when on the road. If my memory serves me correctly, I've fitted these to A10 forks OK.

Sorry, a bit off-topicThanks for the advise all,
Correct me if I'm wrong, but I think you mean 'advice' ; 'advise' is another thing, like a verb *????*
Sorry about the grammar lesson, I didn't pass 'English' at school, but did try and was periodically bashed if I got things wrong, so feel it's my duty to; ahem- *bash* *beer* *smile*

Bit late on this but they are a b"£$%$d to get in. Getting them out - easy with a small flat headed screwdriver. Getting them in led to a serious finger injury when circlip end went down my nail under some force and covered in oil. All better now though. Had some thoughts of compressing the clip with some sort of large hose clip, sliding it over the fork leg and judiciously tapping it into the slider. Alternatively, securing one side with a screwdriver and battling with the other is one I've done a few times now. There is an answer out there for this, I've just not come up with it yet!! *conf* *sad2* *eek* ;) :!

Have a look here (Reply 7).

In the end I used the A65 type retaining cups (so much easier and they hold the bush and the oil seal in place). It was 2 years ago and they've worked perfectly.

Are they suitable for all years of our bikes?
-
Think they should be suitable, alittle work with a dremel may be required, there's a similar thread with details on with the clip from Feked, gets away from the dreaded circlip, only the rocker box to simplify now and these bikes are a pleasure to work on
-
They can be Billybream, but I'd rather it wasn't in my garage quite as much!
-
you mean, you think it's easier than this:

...only the rocker box to simplify now and these bikes are a pleasure to work on
In the July 2021 edition of the BSAOC 'The Star' magazines, they showed someone's modification to put an oblong access plate in the top of the rocker box to make pushrod location easier. I think that might be ok on an early engine but on the Swing-Arm models, an engine brace is on the top of the box so I don't think you'd want to weaken it too much.
-
Seriously? Though I'm not exactly envisioning what you're describing, it seems like an extreme fix for a minor inconvenience. It ain't all that hard.

I got a mate to make up a puller out of threaded bar, a piece of large diameter bar threaded to the top of the forks and a couple of suitable spacers. Put the bar through the yolk, screw into top of fork and draw up to the top using the spacers - really simple and effective.
-
worthluck - my word, that sounds complicated. Use a broom handle or a bit of old threaded rod attached to an old top nut. Should only take a matter of seconds to pull it up far enough to catch the threads with the nut.

That's what I did.

D *dunno2* *dunno2* *beer* *whistle* My mate made it and I cadged it off him - works a treat though. You never know, I may stick it on Ebay as a 'special tool' and charge a hundred quid for it. >:D >:D *beer* *evil* *evil*

Is that including postage?

That's extra *contract* *contract* *contract* >:D >:D >:D *evil* *evil* *evil* *whistle* *whistle* *whistle*

Does the broom handle really work? I would be worried that I would get bits of wood in the forks. Anyway I could not find an imperial broom Handle.
i drilled a hole in and old fork top nut. Filed off the hex and put some M8 threaded bar. Works a treat. And it fits my triumph, bonus.

Sounds about the same level of complication and effort as my set up - so long as it works well!
