About to tackle fork seals...
« on: August 12, 2013, 08:20:00 pm »
       I am gearing up for a fork seal change on my 95 c10.  I have read lots on the subject and feel I can do it myself.  I was looking things over today trying to decide the best action to take and was wondering if I have to remove the fairing to get at the lower triple tree bolts.  I can fit my torque wrench it there but not much room.  I would really like to leave the plastic on it,  just want some thoughts from someone who has done this before. 

      Also why inspecting things i noticed that one side of my handlebars is missing both set screws.  (KB risers)  :-\     I really doubt those are easy to come by so looks like I have to order the service kit just for those 2 pesky screws.  Unlike whoever installed them they are getting thread locker this time.   It's kind of unnerving that i had been riding for no telling how long without them.

easily done with the fairing on.

what screws are you missing, the set screws on the riser block itself? you don't need them, the socket head bolts hold the risers down, the set screws are not important.  HTH, Steve

Yeah it's the tiny allen head set screws that are missing on one side.  Good to know they aren't needed and my safety was not at stake.  As soon as I saw the oil running down the fork with every bump it's been parked for about a month while I gathered tools/parts.

Have you had any of the plastic off the bike at any time?

Speaking from personal experience I was afraid to remove any plastic when I first bought my bike, It looked so complicated. However, once I removed all the plastic I found it wasn't complicated at all. It's just a job that involves removing one piece at a time. Why should you do it? It's a good way to get acquainted with the bike and might uncover something else that needs attention.

I recently replaced fork seals and the fork seal dust boots. A Sonic straight weight spring replaced the factory spring and the front wheel got new bearings. The engine to frame bolts/nuts were torqued to spec. The bike didn't have much handlebar vibration before but the torquing made them 95% vibration free. Too many other things to list but with the age of these bikes it's what you deal with.

I had all the lower plastic off to install tip-over bars.  Engine bolts got torqued at that time.  Practically buzz free.   I have a few days off next week so planning to tackle the forks then.   Just wanted to make sure I go about it the best way since I have never done forks before.

Forks can be a little intimidating, but they are actually pretty simple. I have rebuilt the Showa forks on my dirbikes twice now. One tip...when you are removing parts, especially things like snap rings & bushings, make absolutely sure you note the order and possibly the orientation of those parts.

Also, carefully inspect the fork tubes (the exposed part that slides into the outer cartridge) for any scratches or other surface imperfections. Small scratches can be carefully buffed out with some 400 grit or higher wet sandpaper. Scratches, burrs, dents, etc...can cause the fork seals to leak.

Good luck!

Shannon- I lost a setscrew from my GenMar risers, so I took one from the other side and matched it up at Ace hardware. Cost about 25 cents.

A cleaning tip:
Remove fork tube and drain out old oil.
Replace with a half cup (or so) mineral spirits or other handy solvent.
Cover the top of the tube with your hand and shake around.
Drain out the gunky solvent.
Repeat until the solvent runs clear.
Do the other fork.

Then when you disassemble it all, everything will be mostly clean of the old, rancid oil. It's what worked well for me.

Slight translation: 'Rancid' = 'Smelly'
Old fork oil is not a pleasant aroma...
There are lots of fork seal videos on YouTube. Several are close enough to the Concours to be helpful. That the forks are damper rod instead of fully adjustable is immensely helpful.

Don't know if they are exactly the same diameter, but probably are similar to the Ninja 900 our bike came from.  When I rebuilt the fork on the "Top Gun" bike, PVC pipe from Home Depot was an equally effective but much cheaper seal driver.  Got that trick from a dirt bike riding/fork rebuilding friend at work at the time.

A 3/8" drive torque wrench gets to the lower pinch bolts a bit easier than a 1/2" drive. I was able to get to all 4, with a little positioning of the steering head, with all of the plastic in place.

Well today was the day.  The only trouble I had was the bottom bolt.  The threaded bar with nuts trick worked like a charm.  For $5 worth of hardware it's a must have.  It was alot more work than I expected and I sure made a day of it but after a short test ride I have no leaks. 
     
       Only concern I have now is when i hold the front brake and push down to compress the forks I  hear a creaking just like old bed springs.  It's not audible while engine is running.  Any ideas what's going on?   

Thanks for everyone's advice it was a great help.

Just an update. 

Went for about a 30 mile ride today and the fork noise is gone.  I figure the oil finally got all worked in the the upper forks.  Very nice to be back in the saddle.    Thanks again everyone.
