I have a leaking front fork seal and want to have a go at spannering for myself. Anyone have a 'how to' perhaps with photos and a list of tools?

Thanks!

Isnt it odd, that Haynes, or better yet, Clymer hasnt written a service manual for this bike?

I had the oppurtunity to watch a seasoned Yamaha Tech do this up at one of the FJRTech events. Even he did some swearing. The seal is a real bear to get into place correctly and required more force than most of us would probably want to apply w/o the correct tools.

After watching that struggle, I'd pay for the dealer to do this task, though I do nearly everything else myself.

@James - Odd, no, a friggin relief!! Neither of those wankers know squat about Japanese bikes. Buy the Yamaha manual and use it.

If you decide to have the dealer do the job, consider doing BOTH fork seals.
After working in a shop for 15+ years, if one goes, the other isnt far behind.
There are special tools required to install and remove the seal, as well as disassemble the fork
tubes.
In other words, 'Pick something EZer for your first attempt'.
You could take the tubes out of the triple trees.
This would save you some cash.

Had both my shock seals go at 9,000. Shop did them for me but then I'm not much of a mechanic. If Liquid and OC recommend the shop, i'd listen to that advice and heed it.

Hi Mark, I just had the same problem with my 03 fjr only 15 k miles..[always garaged]..leaking fluid from the left fork leg like a siv..here is how I fixed it. [what you blokes call "spannering it"]..found this trick off of the Suzuki drz 400 forum many yrs ago; but it is also found on other off road or dual sport bike forums....35 mm film.. get some exposed [called the negatives] or not. cut a small enough piece as to fit about half way around the fork tube ..easy to do if it is new out of the canister, already curved...now trim the 4 corners of your piece of film, round them off, sort of..now spray the fork tube and film with any of your favorite lube, wd-40, etc. i used PB Blaster...now slide the film down the tube , past the upper dust/dirt wiper and down into the seal itself... now try to rotate the film around the tube/seal junction//use lots of spray lube [wd-40]...the idea is to clean out the krap/junk/dirt whatever ,that is between the seal and tube...in my case , I knew the chrome tube was in perfect condition, no nicks or dings, that could possibly tear or wear out the seal..so it had to be a contamination issue...most likely bug guts, flying bugs are plenty-full here in the sub tropics....after several minutes of turning and pulling out and pushing in [sex?]...lots of PB Blaster,, the procedure was done , clean up with paper towels and some spray degreaser...do the test ride..Bone DrY...that was the day before a planned road trip to Norht Georgia last week. still DRY some 600 miles and a week later....I have done this trick on several dirt bikes and my Honda VFR... Somtimes it requires the fork to be slid out of the triple trees , the black plastic fork guard and upper dust seal to be remove , for better access and more room for the film to get in past the oil seal and clean it out...Seldom is the seal actually BAD, just dirt stuck in it...turn the fork upsside down and pump it hard a bunch of times....now if your tube is rusted or nicked in the slide area, then you probably do need new seals.....try this before spending needless cash. it costs nothing...and despite what it says in this and other forums, the plastic does not have to be removed to get the fork tubes out. just the right tools and a smart brain..and you do not need some platic hanging contraption to raise the front end...use a simple floor jack..and those that need pictures and a entire web page to do this;;should not even attempt...

side note,,,, yes I know that is not spelled with a k [krap],, but with a C,, []...the software will not allow it to be displayed that way..must be offensive to someone...is nigger offensive?..guess not!...who is the smart one that thought of this kind of programming?...nothing has changed

Just to add, by 15k, the original fork oil is nasty anyway, and as Juperter said, the plastic doesn't need to come off. The recommendation for that is to allow torque wrench use on the pinch bolts. When you look at the torque spec, IIRC, 17 and 20 ft/lbs, you'll note that it's not really a big deal, torque wise, just don't get carried away. Note that with a typical allen wrench and your hand, it's pretty hard to over tighten the pinch bolts.

Oh yeah, and the software is set up for UK slang, not US slang, but the next version might catch both.

Interesting Jupiter.

That trick works on dirtbike seals as well, until the seal becomes damaged by the 'krap.'

Jupiter; Thanks for the film trick. I guess that WD 40 will not hurt the seals, Correct?

Juipiter's fix works well. I used it a couple of times on my BMW K1100 over the years and it cured all the weeping each time. However, I used a 4 thou feeler gauge.

mmmmmmm. I.ve noticed a leak on my YZ400F right fork. I'll try that trick before I replace the seals. But the bike is 7 years old.

thanks for the info OCFJR , I never thought about the aspect of the software being setup for U.K. slang...very good!...i apologize for my stupidity...makes perfect sense , now that I think about it....

>yes wd-40 will work well in flushing out the krap, and is good for the rubber seals.

> I really like the feeler gauge idea, should give one a better handle to hold on to as you work it in around the tube.

> must go now, time to put up the Hurricane shutters AGAIN !!!!!

No need to apologize Jupiter, it's all about learning here. Good luck with Wilma, she looks like she'll be down to Cat 1 by the time she gets to you.

Jupiter - thanks for the tip. Will try this out ASAP

Others: your advice about the work is noted. I am surprised the task is so scary.FJRTech.com make it sound reasonably simple but I wondered what the special tool is.

Todger - tried the 4 tho feeler gauge but it goes all limp on me and makes no impression on the seal (wonder if Viagra might help).

What sucks, is this is on the old forum. I still get e-mail notice from the old site, but NOTHING from the new. Im Bummed!

Oh, one other thing we didnt talk about, NOT nicking the seals lip, or sealing surface during instalation onto the tube!
Lube the inner fork seal with LOTS of fork oil.
I actually use a piece of plastic wrap (used to keep food fresh) as a shield and after streaching it over the fork tube top and lubing it, slide the lubed seal onto the fork tube.
This really helps with initional install over the top of the sharp edged fork tube.
