hugo Posted July 5, 2004 Report Share Posted July 5, 2004 (edited) Got my new Sherco, did'nt take time to get myself a set of fork protectors and what needed not to happen happened... dropped the bike on a sharp rock and dented on of the inner tubes of my fork. The seal is not leaking but I am wondering if I should try to reduce the sharpness of the dent or if I should not touch it. I suspect there is some kind of treatment on the fork so that it should not be sanded/filed... Any experience?

landrover Posted July 5, 2004 Report Share Posted July 5, 2004 i think your best bet is to get another tube,then a set of fork guards before you go out again Quote Link to comment Share on other sites More sharing options...
beta boy Posted July 5, 2004 Report Share Posted July 5, 2004 i did this to my beta really big chip in the slider so i took it home wet and dryed it to get rid of the sharp stuff and get it level again. then i put a good splodge of super glue in the chip waited till it dryed fully (few hours) wet and dryed that back with a really fine paper (1000 grade) i did this till the super glue was level with the slider surface then just used metal polish to polish that are up all smoth again to make a good surface and i have not had any trouble since it is worth a try cause if it does work for you it could save a lot of money Quote Link to comment Share on other sites More sharing options...
wonder boy Posted July 5, 2004 Report Share Posted July 5, 2004 To save you time and money, your best bet is to buy a new tube from your dealer or where ever you can get it from. It will only cause problems if you try and repair it your self and cause more damage. Gavin Quote Link to comment Share on other sites More sharing options...
beta boy Posted July 5, 2004 Report Share Posted July 5, 2004 and what damage could this cause apart from reck the seal which is about Quote Link to comment Share on other sites More sharing options...
wonder boy Posted July 5, 2004 Report Share Posted July 5, 2004 If there are any shape bits it could damage the inside of the suspension. Water could possible get in and damage more things.

beta boy Posted July 5, 2004 Report Share Posted July 5, 2004 well all i am saying that it worked for me and it has been like that for 3 months now with no problems i was only trying to pass on a tip and then you go and say if you do it ur self it wont work when it has obviously worked for me Quote Link to comment Share on other sites More sharing options...
hugo Posted July 6, 2004 Author Report Share Posted July 6, 2004 Well so far it is not leaking and does not seems to interfere with the regular movement, I am just guessing the seal will deteriorate quicker because of this sharp little spot. If I bust the seal in the next hours of use then I'll consider trying to repair first than change the tube if it fails. Anyone already bought a new tube? what price range are we talking about?

sirdabsalot Posted July 6, 2004 Report Share Posted July 6, 2004 Hugo-- If you leave a protrusion on the fork tube it will damage the seal. A small dent that does not protrude will not. Use a file or course sand paper on a hard block to knock any protrusion down, then sand smooth with fine sandpaper. If there is any leaking it will only be when the dent is passing the seal. If you leave a protrusion that damages the seal, it will always leak. Repair it, what do you have to lose? Richard Quote Link to comment Share on other sites More sharing options...
bigfoot Posted July 6, 2004 Report Share Posted July 6, 2004 Hugo I chipped the titanium off one of the fork legs of my 2001 gasser on it's first hour out of the box. I bought a new one and it cost about Quote Link to comment Share on other sites More sharing options...
toofasttim Posted July 6, 2004 Report Share Posted July 6, 2004 The other alternative is hard solder. Quote Link to comment Share on other sites More sharing options...
jtt Posted July 6, 2004 Report Share Posted July 6, 2004 I'm with sirdabsalot on this one. I've seen lots of fork nicks fixed with a good flat stone. Just take some fine emery or better yet a small flat stone and carefully smooth the surface where the dent is. This will remove the sharp bits that will damage the seal. If the dent is small enough, the seal will maintain it's seal pretty well and not leak. WB has the right idea about fixing things "the right way", but in this case the stone may be a passable fix, as long as the dent is not too large.

stuessenhigh Posted July 6, 2004 Report Share Posted July 6, 2004 A new fork inner for a Beta is about 110 pounds. I know 'cause I scratched mine and the seal kept leaking. BUT...I did a repair with araldite, and rubbed it down smooth, and it has never been a problem since. (over one year now..and I ride at least once a week). I agree (of course if you have the money) get a new one...but if not...try the repair first...if it dont work, THEN buy a new one Quote Link to comment Share on other sites More sharing options...

Had a well used 1984 TY250 and used that fix worked great! Quote Link to comment Share on other sites More sharing options...
copemech Posted July 8, 2004 Report Share Posted July 8, 2004 THESE REPAIR IDEAS ALL SOUND VERY GOOD, not sure what araidite is? I also know of a metallized epoxy resin called DEVCON F that is sold by Grainger here in the states. It may work well too, but I hope I do not have to try it! Beta Boy's original idea reminds me of a fellow demonstrating a form of super glue at a trade show I attended this spring. When he wanted to build up an area in a surface he added a special powder to the glue and when it hardened it was totally machineable. You could build up areas in chipped ceramics, metals and such very easily. Turning the tube in a lathe and finishing with 600-1000 grit would polish the tube to a fine finish when the repairs are completed. I usually try to fix things to get by till the end of the season then either replace everything that needs replacing or just get a new(or newer) bike!
