Title: Using the Stantion puller tool
Post by: MJM_58SR on 04 Jun, 2020, 14:30
Hello all
Just wondering if the tool can be used to take the forks apart as well as fit them.
If so how does it work please?
Thanks

Short answer. No! Unfortunately you need one tool to pull up the stanchions and another one to remove and refit the oil seal holders. It does help to have a tool to fit the new oil seals into the holders. Then three hands to remove and refit the horrible circlips unless you are dealing with an A65 then there are no circlips. Then you need a vise to grip the stanchions while you under the nut at the end so you can remove the bushes. Good fun isn't it.

Easy way to fit the seals into the holders is to press them in with your thumbs as far as you can, then screw the holder onto the fork bottom which pushes the seals into place. The BSA tool for the job is a rather substantial drift.

Hi all thanks for the replies
I guess I didn't quite get the question right.
What I was trying to find out was is there a recommended method of getting the Stantions off the bike. Just preparing and wanted to know just in case I have to take them off again if they don't go right
I took them off with a mallet and a piece of timber but that was before I'd had them nicely coated etc and got new stuff!

With wheel and mudguard removed and pinch bolts losened screw the tool (less nut and spacer) into fork shaft, steady the fork bottom then hit the tool with hammer to break the taper.

To replace the fork screw tool into fork, extend fork, insert through yoke, put spacer and nut on tool and draw shaft into taper. Yes the forks tend to telescope when you do it.

Thanks Julian
I Have the same tool as that and earlier I tried to remove the stantion I had put in using the method stated... I know how they make the tool now, they make the individual bits which are then assembled, the bottom screw part is spot welded on....a couple of sharp taps with a hammer and the weld cracked on the bottom of the tool - quality I think not. I got it from the classic bike shop so may have to let them know!
Anyway I'm sure it will all be my fault so I will just drop a bit of weld on it and hopefully be sorted.
Thanks for the replies
Regards
Martyn

The original BSA item is a robust item with no welds, mine been in use since I bought it from Ray Fisher, now Britbits, in Christchurch in 1973. A shame that modern item is such poor quality.

Good morning,

Please send the inferior tool back.  There are too many shoddy parts out there and if we accept them then we are encouraging more shoddy parts and tools.
I have recently sent back plain clutch plates that were not flat and a triplex chain that had a connecting link rather than continuous.  A bit of a hassle but worth it in the long run.

Dave.

Hi Dave
I will get onto them when they open up and let you know how I get on (or don't which is sadly mostly the case these days)

Hi,
    You could make your own from discarded bike bits, here's a set for the A10 and A65 made earlier. You probably recognise some of the bits.

If you want more info let me know.

Best wishes...

Just to update you all
I have good news
I've spoken to classic bike shop and I have to say they were very good.
No quibbles, sending a replacement and want the photos to raise with the supplier. You really can't get better than that.
That's excellent service in my eyes.

Yes. Good result and a good response from the Classic Bike Shop.
We all need to do this and through the shops we can get to the supplier/manufacturer and get standards up.

Hi Bess
Apologies I didn't reply to your post.
I did think about making one up using the old tops and some threaded bar but I decided to treat myself!
Thanks for the info though

Hi Martyn,
                You're welcome, happy to see you are sorted  :) :)

I too have been tempted to treat myself but I always need it in a hurry so use what I've made. I keep saying this is my last build so I figure if I buy one I'll never need it  :-\ :-\

I'm glad I'm not the only one doing a last build. Although in truth this is another last build and this is very definitely the very last last build. Mind you, I did see a bantam scrambler type machine in my mates workshop. He's had it for several years and not touched it so I might just sorta look at it for him and suggest  things. Its half hidden behind an old Fordson tractor. That's quite appealing???????????
