Fork Oil Seal (mkI) - openroad - 30-06-2012
looking to do the seals on my mk1 850. just ordered them on ebay. i've done this job on a few bikes in the last five years any thing i need to look out for when doing this job on a tdm. what weight oil and how much per fork are you gental foke using? my forks are squeaking at me which is making me think i've go no oil in or very little them which is kinda worrying. (seems fine while riding) the dust seals are looking a bit crappy tho. just passed an MOT today with them.

Fork oil capacity is 395cc per fork. Haynes say 10w oil but I think Yamaha have it at 7.5w. [img]style_emoticons/<#EMO_DIR#>/unsure.gif[/img]
I doubt very much if you'll get the old seals removed without damaging the fork bushes, unless you can force them out without having to separate the upper and lower parts. Chances are they're already damaged if there isn't any oil in the forks.
I'll say it again, but ya really will need a Haynes manual if you have to separate the forks. There are various bolts and washers, adjusters, rods and springs in there that would be difficult for anyone to accurately describe. Even the parts diagram takes some working out !

Metal Slide 1 & Metal Slide 2 are the upper and lower bushes.
Are you sure you need to do all this matey ? If it's handling fine and passed the mot the squeak might just be summat else like the clutch cable or the brake hoses catching.
I wouldn't go near my fork seals unless it were absolutely necessary, jobs a PITA.

Have you got the pdf parts file for your bike openroad ? Very handy with the exploded diagrams and you also get all the correct part numbers.
If you register on JBX's toptastic site you can download the files for free, registering is also free ! [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

Fork Oil Seal (mkI) - James - 13-03-2015
For reference: Mk1 oil seal removal.
Not sure if this has been mentioned in the thread up to now but...
Once you're ready to separate the tubes from the sliders, it's a lot easier to do this if you gently warm the slider around where the top bush sits. I did mine with a blow torch but a hot air gun or boiling water on a rag wrapped around the top of the slider would do the same job. A gentle heat is all that's required, aluminium is a good heat conductor with a relatively low melting point! If you're lucky you might save your fork bushes. On mine, one side was okay the other ruined, but I'm replacing bushes on both sides anyway.
As mentioned already, use genuine Yam seals. I replaced seals on my FJ1200 three times in short succession before I ordered OEM, they're not much more expensive anyway.

Good thinking Jim, godda be worth a try. Anything that makes the job easier. :good:

I only split them if I'm fitting new bushes for seals only I use the hydraulic method to pop the seals out works a treat âº
Fork Oil Seal (mkI) - zardoz - 13-03-2015
My seals went last year. I managed to change the seals on their own, without seperating leg and slider.Â
Top cap and spring removed, let tube down into outer.
Use a very small drill. Drill into seal to start small hole in steel liner.
Screw a small self-tapper into steel. same on other side of seal
Use piece of wood or similar to protect top of slider, you can lever seal out quite easily.

When you say #14 & #16, are you referring to this diagram?Â

Â
I'm about to tackle this myself and want to ensure I order all the right parts. Speaking of which, will these fork seals do the trick?

Â
I've watched Delboy's video here:
https://www.youtube.com/watch?v=vrmYJgcGX30
Â
I believe that setup is similar to ours enough to copy the method. Anyone care to verify and/or elaborate on possible gotchas?
Fork Oil Seal (mkI) - bjorge - 07-01-2016
I think I'm not the only one having run into trouble with aftermarket seals. Hat do change a couple of those after a few days - used genuine Yam ones after that.
Â
A comment on the video: This way of separation of fork tubes are ~ 43.55% certainly ending up in warped bushings.
Â
Consider an alternative way:Â https://www.youtube.com/watch?v=QAK2GrWaTu0
Fork Oil Seal (mkI) - loadedmind - 07-01-2016
Bjorge-> From the Amazon link, do those seals appear to be the ones you ordered? What all other parts did you replace in the fork seal job or were they just the seals themselves?
Fork Oil Seal (mkI) - TDrummer - 18-03-2016
Just read this entire thread. What a trip!
Â
I'm thinking I'll remove my forks and bring them to a pro for rebuild when the time comes.
I think I can swap the oil myself in the meantime...
Fork Oil Seal (mkI) - bjorge - 28-03-2016
They're not that complicated. Not much you'd service other than oil seals and bushings - both easily swapped.

:wifgeni:
Its not tricky and if not done fur a while then worth replacing bottom bushes anyway so doesn't matter if ya ruin em.
I would def do em yersen-----we can talk ya through stage by stage!
Havin said that, if seals not leaking then just changing the pickled onion water will make a big diff!!!
Fork Oil Seal (mkI) - pharland - 19-07-2016
Looks like I may need to replace the seals and oil on my 4tx.
Googled first and landed on Dappers youtube vid, so have saved that to look at again. Â Have been having a read here and making notes.
Quick Q. Â Do we have a thread for the MkII, or are they pretty much the same as the MKI?
Oh. Â In the meantime I have invested in one of these. Â If it helps me thru' MOT next month, I can sort the seals and oil change later
