fork seal blown.

Post by Doug Herr » Sun Oct 05, 2008 3:24 pm

NO jokes about sea mammals and fellatio please. The wife just noticed a small oil slick under my bike and I find fresh oil on my right fork. I see that Fred sells "MSRHP Fork Seal & Wiper Kit" for $29.95. We have not been riding much these days, but I do want to keep the bike in happy/working order. Any advice on the "best" thing to do in this case? -- Doug Herr doug@... A16 in Oakland, California

Doug - Pass on the enigmatic tales of superglue and radiatore sealant and get'er fixed properly. I installed Fred's MSR seals and can recommend them. Although I'm not sure how much better one seal and wiper kit is over another. Longevity might be the only difference but who knows. I've heard some folks say the OEMs are as good as it gets; a cheaper set Fred sells carries a lifetime warranty. Again, before I'd sell you any of them, I'd like to see the proof myself. Just make sure when you're done you rub a touch of 'dry' lube on the forks before entombing them under das boots. This will reduce stiction right out of the gate. I use Pedros Extra Dry lube from a bicycle store but a spot of fork oil is fine, too. And don't forget to pickup fork oil to complete the job! Of course the KLR650 braintrust is always at your disposal. This is a good website to get you started... http://www.geocities.com/TheTropics/Breakers/8462/KLR650/ForkSeal- RR.html

Doug - one added reminder, I used one of the old seals and a piece of wood to drive in carefully the new seals. It worked fine for me instead of making or buying a special seal driver. No need.

Here's a couple of sites for seal r & r. I used the air method a few months ago on both my bike and my wifes. It works well. I left my oil in when I pressured up the forks but covered them with a cloth, go slow with the air as you pressure up. Your fork will extend full.It worked find. I did find it took some finesse to get the new seals in far enough to get the keeper spring to seat. I used a wide flat screwdriver and took my time. http://www.advrider.com/forums/showthread.php?t=207150 http://www.geocities.com/TheTropics/Breakers/8462/KLR650/ForkSeal-RR.html

Hello Doug, I am most likely the most recent 'fork-seal' replacement on this list...and I only had one thought when I saw my seals were blown at the midpoint during the GDR last month.... OEM seals. period. (Not that being most recent, makes me most smartest.) shrug. Just the most recent.... In my five years of reading list wisdom, OEM is the one that has disappointed the least--none that I recall--and many that installed 'trick' fork seals. The failed seals I replaced, under the watchful eye and tutelage of Jeff Saline--were aftermarket seals--and they did not last 5,000 smiles--installed by PO. I know the bike was not jumped or flown--thus abusing the seals during that 5,000 smiles. Were they properly installed? I trust that they were, based on the PO general experience with moto's over their lifespan. I also could not believe how filthy the oil we drained out was in ~10,000 smiles. It hardly qualified as oil, more like liquid gunk. The aftermarket seals were only ~66% of the thickness/height of the OEM seals--so much so, we initially thought the installed seal was only a wiper! Pay attention to the orientation of the 'parts' in the bottom of the fork tube. ie. Clymer Manual, pg 259 Ill #30 part # 19; guide bushing The parts diagram is not helpful, and is not very clear. We watched the orientation carefully during disassembly--only to discover, one was cup side up, one was cup side down. If you full disassemble the forks, be sure to thoroughly clean the inside of bottom fork leg. I finally pushed high pressure water into it and blew out the crap. I had worked for an hour attempting to 'cleanse' the residue that I finally removed in

Revmaaatin - Where is the love for the aftermarket? I'm still attempting to return to nature my new MSR seals. So far nearly 10k smiles and all systems go. As for pressure washing the fork internals. I can't recommend this to viewers. You'll never displace all the water especially vapor. Far better to flush with fork oil for a tiny incremental cost. Once you drain them and pump some fresh thru, it's clean enough. For the record, the dive of death (a big granite drop in an undisclosed location in the Rockies) that destroyed one of my front OEM seals did nothing to my new seals. If I recall, you've had a fork brace on your KLR which I can almost guarantee accelerated the demise of your oil and seals. We're not talking grassy knolls conspiracy theories here. I just pointed the following to a buddy who has a brace on his. I'd never used or seen one before but my uncanny attention to detail of his predicts bad juju. If you look at the force brace installed, you had to force-up the bottom of das boots to get the brace to fit. In doing this you reposition the (holes) drain ports from the fork receiver up onto the tubes themselves. (eh hum) Crap is now going directly in and onto the tubes and compromising your seals and oil. For extremers and off- roaders, unprotected fork tubes is bad juju and explains the fork julius you were surprised to find. This is how important these boots are to prevent contamination and why the manufacturer puts hose clamps at the top of das boots. Reinstall some MSRs and re-seal the deal. Provided the integrity of the das boots isn't compromised, you're very unlikely to see this happen again. Brian ps - Did you get my response to your gumbo mud destination post? I didn't forget you 'in the Valley.' Actually I thought I had a clever response to you. Anyhoooo, that remaining 1% mostly represents those that let it sit in the garage.

You may well need to replace the seals, but on the theory that the "best" thing to do is the simplest and cheapest, try using a thin piece of plastic (the electronic access cards they use in motels are about right) under the seal, to wipe out any bit of grit that may be trapped and causing your leak. It's easy, costs you nothing, and if unsuccessful leaves you no worse off than when you started.

<><><><><><><><><> <><><><><><><><><> Doug, My money would go to new OEM seals. I think they were about $27 at the dealer when I picked them up for Martin a few weeks ago. Someone suggested you try cleaning under the wiper. A local Moto-X shop sells a piece of plastic just for this operation. I've also heard you can use a piece of film from a 35mm camera. Maybe get a scrap at the local photo developing shop.

SNIP <><><><><><><> <><><><><><><> Brian, The forks were totally apart when Martin used the pressure washer to clean the inside of the sliders. It worked well. No worries about trapped vapor. I think the inside was also dried with compressed air and a clean rag on a stick. For the cost of OEM fork seals I'll stay with them. Mine are still good at 27,000 plus smiles. I think the fork brace may have contributed to the leaks but nobody will ever know for sure. Martin didn't reinstall it when finished with the forks. He was hoping to decide after a bit of riding if he'd put it back on or not. I'm betting he doesn't.

Interesting use of playing cards...and a whole new reason to viva Las Vegas! Like I needed one... :)
