Title: Tools for forks
Post by: ShaunMac on 06.05. 2014 17:08
Hi all,
I'm hoping to save some money by making my own tools for working on the front forks. I've hogan old cap to make a puller but I was wondering is anyone had the dimensions and maybe a picture of the end of the tool for removing the nut for stripping forks?
Cheers,
Shaun

Hi Shaun.
Do you mean a tool to remove the oil seal holders from the fork leg. A good quality strap wrench might help, but I have made a tool from hollow tube with id to clear fork inner tube and od to fit inside seal holder. The tool then has a pair of tangs or dogs to locate into the slots at the bottom of the seal holder. The tool is then finished off with two tapped holes at the top to enable bolts to fastenen to aid turning during dis-assembly and re-assembly.
If you would like some dimensions of the tool please advise.

That's the one.
Some dimensions would be great.
Thanks.

Hi Shaun.
OD = 1" 7/8
ID = 1" 1/2
Overall length of tool = 9" 1/2
Two tapped holes on centre line 1" 1/4 from top, I used 5/16" whit bolts as handles.
Dogs or Tangs are off the centre line, 1/8" thick x 3/8" long x 3/16" deep. So basically reduce OD @ end to 1" 5/8 x  3/16" length, and produce tang to 3/8" width.

Made two or three of these and my mates made a couple, never strong enough tabs on them, possibly our engineering skills are lacking something, best thing I did was buy the purpose made tool, it's worked 100% every time I've used it

I've done the same kind of thing for a Guzzi g/box. I bought a box spanner of about the right size and then built up some tangs on one end with a welder. Left me with a useful hex at the other end to get a spanner on.

 Some piccies would be good- I don't have a need for eh fork tool, but surely someone will, but I do have a Gutzzi box I need to dissect ....cycloB....?

I can feel a moderator breathing down my neck - might be a little too far off piste on this now. I'll see if I can turn it up amongst the detritus in the garage and then PM you. Happy to send it out on loan but would want it returned as I have aspirations for another big round barrel.

I was watching this post as my Ariel forks were leaking, well one side anyway. Tackling the job today I have made the seal tool and a "draw up plug". Just removing the forks from the yokes is easy enough but couldn't get them back up as the stanchion just drops back inside the leg as it all gets pushed up. The plug (3/4" dia screw cut to 20 TPI.) screws into the top of the stanchion and the 10 mm thread is grab-able to wind it up into the yokes so the top bolt can be screwed in.

 Yup CycloB., maybe should be in 'Home-made tools', but will finish the diversion-if that's ok?-
 will likely make one from some 1-1/2" tube (1,3/8"-35mm ID) I have- made one similar for my (conical) front wheel bearing retainer but lugs are round and a bit further out as per photo that's the round nut in the end...
 Cheers
