Fork Help Please

There is a large collar around the bottom of the fork sliders. It is too wide to fit through the seal, or at least it was in my case.

 

The large collar is the lower bearing for the slider tube. That will help pop the old seal out. Save if it is in good shape. Are you willing to slap them together and find out if you did any damage? If not, here we go. As for forks (here I go again) check out Franks Maintenance and Engineering (http://www.frankmain.qpg.com/). He'll set you up with new sliders for about half the dealer cost, and that is delivered to your door in North America. SecaMan, the forks are different (valving) between the Max and the Seca but the design is similar. They both have dust seals, circlips, and fork fluid seals. The 650 and 750 both run a 42mm diameter but they are different internally.

 

hmm ok

i was thinking are they the same length?

would they change my angle? etc

i'll have to see his forks then

he said he had to look for them! :roll:

 

I don't know about the length, I never swapped them. I don't have them immediately handy so I can't run right out and check them either. I don't expect they would change your angle so long as you clamp the tubes in the same place as the stockers. If they are a little longer, just clamp a little lower. Best I can do for you bud. Good luck!

 

82 air forks too , i replacing the seal on da forks whilst waiting.

i found on mine there is no place for a tool or bolt for the inner tube thingymabob , here's a pic of it , just undid the allen bolt on the bottom of the leg and it came out....

removed my ok circlips and just yanked out the main fork tubes and the seal popped out with it...

Also there was heeps of crud and slush in the bottom of the tubes and in the antidive section too [in another post] , all up it really did not take to long to get it all in bits , a good clean and reassemble with new seals ect will last another few years again [i do not think its ever bin done on this bike] cheers....

 

i think this is the photo you were looking for

 

nope , what i try to say is there is no place for a nut or bolt....or anything

 

And a further update , for air forks with antidive .

Right down the bottom of the forks is this thing [pictured] , one has to give the bottom fork leg a few [5 or more] good drops on a rag on the floor upside down of course to get it out.

Around that thing is a plastik piston type ring , mine had sludge in both in the ring gaps and where it fits so it was jammed and not movable.

i carefully removed said ring , cleaned the gaps and used fine wet and dry on the piston to make shure it was free and could turn around.

That thing and the ring seperates the top antidive section to the underneath side of the antidive system in the fork leg so it would need a fairly good seal....

 

As for your damping rod, sounds like your stuck using an impact gun. What does your book suggest for your type of fork? My Haynes doesn't mention anything about a damper without the fluting. Another thought, I've seen a wedge type tool that is rather an obtuse pyramid that will pop onto the end of a 3/8" extension and wedges itself into the damper top. Might be your fix. I don't know where I saw it, I'll try to find the reference for you. All your work is exposing the fact that I didn't do half the work I needed to to properly overhaul my forks HooNz, now I've got to go back in to ensure mine are working properly! Thanks for taking the plung, I'm going to use your suggestions!

 

Thannnnks alot robert , i hope it does assist , see i do not have a book as yet so was going in the deep end , and of course assisted via these greate forums here on xjbikes.com.

thats probably why i found that thing [i'm too lazy to look on the yam parts page using dialup] , whats that down there i see's and why does it turn a little from the lower side holes and why no come out?

i am glad i tried.. as like you it would bug me later on if i found out a cupla months from now , i have no before test so i'll only know its ok as it should be when i get this thing on the road..

and by the way as one see's the rods are out and were no problem to get out tis why i made the comment about the tool , maybe mine is [oviobsly] different..

 

Perplexing to say the least. I've never seen a damper without the ridges on any of the Yamaha, Honda, Kawasaki, or Susuki's I've rebuilt.
