Guys, Welcome any tips on how to separate fork sliders from stanchion tubes. Anchor bolts and oil level grub screws loosened but still can't separate them. Bike is 15T (1966) Thanks

Forks

If it's like the normal forks it's probably been allowed to get water in and rust. Try tipping some parrafin down there and tap the outer leg at the bottom.Try winding the spring back and forth. Last thing put a round lever in the hole where the clamp screw goes and locate the hole in the inner section and work it all directions .
If that fails you need heat and maybe New springs afterwards

Many Thanks Ken, fork now turns real easy and have managed to pull forks down about 50mm but still wont give. I will try your tips. Just wanted to make sure I hadn't left a nut/bolt fastened that I wasn't aware of!!

Sounds Like...

Post  ChrisTurner on Wed Sep 24, 2014 6:15 pm

... you have reached the point where the oil seals have abutted the top bush - look at the parts diagram to see what I mean. If that is so, then you will need to give the sliders a pretty robust pull to get them over the top bush and another to do the same with the bottom bush. This will probably destroy the seals so new ones will need to be fitted, and that will require a whole new topic on its own. Chris

Thanks Chris, You make the refitting of seals a daunting and difficult job. Is it a specialist task?

Fork Seals

Post  ChrisTurner on Wed Sep 24, 2014 6:46 pm

Not difficult and definitely doesn't need an expert, just plenty of patience and lubrication, but like another activity you might think of. Very Happy

When you get them apart, IM me and I will send you details of how I did it. Chris

That's really kind of you mate. I will. First project so finding it all overwhelming at times. Finding the right parts can also be a minefield

Oh sorry. I thought you had the fork legs off and just had the springs stuck in . Yes the fork seals will stop you espically when the rubber is hard . New ones are not bad to fit . Plenty of lube and a sleeve to guide over the bushes helps .

That's right Ken, forks are off the bike and on the work bench they're still attached to the stanchions which I'm trying to separate. forks twist easily and will as I mentioned move about 50mm but that's about it mate.

fork tube removal

Post  piston 197 on Thu Sep 25, 2014 8:31 am

If these are the lightweight forks as fitted to plover etc, there is a circlip inside that needs removing about 1/2" down the inside of the tubes, the grub screw loosens the inner plunger shaft and some movement will be achieved by you removing this , but without removing the circlip you will not be able to separate the tubes from the upper "H" section

Not knowing what constitutes heavy forks I don't know what they are John. The bike is 1966 if that helps. I will however see if I can see a circlip. Many thanks

1966 model 96/95

Post  piston 197 on Thu Sep 25, 2014 9:32 am

Well if it has a 15T/16T engine it will be either a plover 95 or a model 96 and will /should have the lightweight forks these consist of a spring pre loaded onto a shaft held in the top section by a circlip, a long damper rod with a slot in it, a screw from the outer lower tubes hold this rod in place, this is about 1 1/2" inches up from the wheel not holes in each leg, if you have removed this screw, the damper rod may just be rusted in the base of the legs, if so clamp the top section in a vice, place a bar through the wheel spindle hole and belt it with a mallet, if you send me a p.m with your email address I can send you a picture of the fork assembly.
If you mean by grub screw you are referring to the ones through the mudguard clamps and you have not removed the two screws at the base of the sliders this could also be your problem
