OK so after my trip I have a load more victims (fork legs) to practice on banana.gif . The set that I rebuilt and musta bodged somehow, and the set from G which I also fegged.

Does anyone with a mkI who has done a fork rebuild have the old seals still? If so, I would be very interested to know what size they are (its marked on the edge). The forks I rebuilt originally had much shallower seals than the replacement seals I got from Yamaha (which I assumed were correct). I have just taken apart one of G's forks and it has the same shallow seals as the first set blink.gif These shallow seals come nowhere near the retaining ring when seated! So I'm guessing the deeper ones from Yamaha are correct but would like confirmation.

G whomever rebuilt your forks was a hamfisted bassad. The top bolts were so tight that all my weight on the end of a 2 foot bar was needed to shift them (they only need to be 23Nm!). The allen key headed bolt at the bottom is so tight on one leg that I just cant shift it ...yet....gonna need some air power me thinks. Also one of the retaining rings isn't retaining blink.gif !

Trying to think of a method of seperating the forks without using the slide hammer method which fegs up the bushes....any ideas?

Tried a few tricks to seperate the tube and stanchion without success. so the ole slide hammer feckin bush method was initiated. rolleyes.gif

I don't think these ridges (that can be felt with a naked finger) are helping the sealing (argh arrgghh arrrggghhh) properties of G's fork!: Attached File  G_fork_ridge.jpg   29.8KB   122 downloads

Dap, the old seal I have did not have the dimintions marked on it. This one.

It measures 10.75 to 10.80 mm thick.
Maybe the "allen key headed bolt at the bottom " has lok-tight on it, as per spec. Might try heating it up. Good luck!

Thanks for the info Tom.

Is that measurement of the hard edge not including the actual lip of the seal? I guess your seal doesn't have a gap between it and the retaining ring once fitted?

So both my old seals and G's seals are the wrong depth!

??
Lip of the seal does not extend beyond the sides. Top lip is even with the top, outside of the seal & bottom lip is aprox 1.5mm recessed from bottom of hard sides
Gap between it and the retaining ring once fitted? If there is a gap, it is so minor that it is of no consequence.
I took measurements, vertical, of all the inside steps, location of clip, thickness of retaining washer, etc., when I was screwing up my 1st bush & seal installation. But they don't make sense to me now. I will do that again when I do the other fork & make a nice drawing so it is clear.
10.795 mm measured on a new seal. Forgot I had one & had done this before.





Dap, how thick are the seals you have? Does the lip extend past the outer edge? Don't sound right.

Thanks again Tom good.gif . The old seals I have removed; have a lip that extends beyond the outside edge. Your pic above is the same seal as Yamaha sent me, with the outer edge the same height as the entire seal! I also got some aftermarket seals and they sent me the shallower ones! Maybe Yamaha used seals with shallower outside edges in '91 and then changed the design to the one shown in your pic. huh.gif

Hi !

I am experiencing the exact same problem today, only the part number is a bit different. I got seals numbered 5VU-23145-00, seemingly belonging to a FZ1000 or something like that. They don't fit, being too thick. Goning to my dealer tomorrow, a bit angry - my teflon bushings lasted the first dismantle, but not the second one ranting.gif

How did the 2006 story end (if you're still a tdm'er) ?

Bjorge, if you are asking me.
The problem I had was, of course, my own fault. Like I said my looong post #80, I did not have the top bush fully seated.
I pulled the 2 fork pieces apart again by just holding them in my hands. I properly seated the upper bush & everything went very smooth after that. Pushed in the dust seal with my fingers, as it should be.

Don't know what to tell you about the part # on the seal you have. 'Cept this:
In this post,
http://www.carpe-tdm...&...post&p=9947
Steve psd said:
"My parts list, current as of just a year or so ago, shows the fork seal as part # 3VD-23145-00-00. 3VD is the Yamaha model number for a TDM; 23145 is a fork seal. Your seal # 3GM-23145 is for a 1990 FZR1000."

Well, I had the right seal. Yammie parts often interchange. It measured approximately 10.75 to 10.80 mm thick. Did you measure your seal? Maybe you are having the same problem I had without having top bushing fully seated.

Sadly, I no longer have the TDM. unsure.gif
Traded it to a guy last spring in part trade for a smokin hot deal on a fully farkled, low mile. tons of spares, prepaid services, still under warrantee, 2006 Buell Ulysses.
He turned around & sold the TDM in two days for less than I would have. Then he bought a used GS. Boo! Just when I found out a friend wanted the TDM. Bummer.
I never did change the oil or seal in the left fork. blush.gif
