gazzaecowarrior Posted July 24, 2009 Report Share Posted July 24, 2009 Hi there. Just changed the oil in my 04 Beta Rev 250 forks. Upon assembling the forks I found that the allen bolt which is the drain bolt on the left hand fork seems to keep rotating. It has tightened up to a satisfactory torque feeling but it rotates when you try to really tighten it. The thread is abseloutely fine. Is this normal ? It is certainly tight enough to not come loose but the right hand drain bolt tightened up to a point it couldn't go further and I expected the same of the left. I appreciate the left and right are tottally different with one being a damper and the other a spring. I am sure the last time I did the forks I didn't experience this. Is it ok to leave it like this ? Quote Link to comment Share on other sites More sharing options...
munch Posted July 24, 2009 Report Share Posted July 24, 2009 that is because it is turning inside , probably wont leak but not ideal Quote Link to comment Share on other sites More sharing options...
tt5th Posted July 24, 2009 Report Share Posted July 24, 2009 You need something to hold the damper assembly inside the fork to stop it rotating as you do it up. You can buy/make a tool to do this - welding an appropriate size bolt onto a rod for example. But you could try a broom handle, it's worked before!

gazzaecowarrior Posted July 24, 2009 Author Report Share Posted July 24, 2009 Hi guys, this isnt on the damper side. This is on the spring side. I realise it is turning inside. Quote Link to comment Share on other sites More sharing options...
nzralphy Posted July 24, 2009 Report Share Posted July 24, 2009 Take the spring out and have someone press down on the rod inside the fork. Quote Link to comment Share on other sites More sharing options...
gazzaecowarrior Posted July 24, 2009 Author Report Share Posted July 24, 2009 Thanks for the advice. I am on my own tommorow so wont be able to get anybody to help me. Would I be able to get the same effect from strapping the bike down with ratchet straps till the forks bottom and then try tightening it up ? Obviously this would be with spring in and fork cap screwed in. Quote Link to comment Share on other sites More sharing options...
rlracer Posted July 25, 2009 Report Share Posted July 25, 2009 As per some of the other post put together. Take the fork off the bike , remove spring, drain the oil in a clean container- i'm assuming you have clean oil inside now, insert broom handle,turn fork upside down, apply pressure againt the fork pulling down ward to the floor, tighten the 8mm allen with a battery impact or lightly with a air impact. Done several this way at the nationals in Tennesse last month. Take about 10-12 minutes to a fork seal on the left side form taking it off the bike to back on.

gazzaecowarrior Posted July 25, 2009 Author Report Share Posted July 25, 2009 Did all that. Used the broom handle. Couldn't tighten it up any more. When I put forks back together and in the triple clamps with wheel on it still rotates. I think I am just being over fussy. When I say it rotates I am really pushing hard on the allen bolt for it to do so. I think it is satisfactory. Would anybody mind having a go at turning their left fork drain bolt and seeing if it roates under pressure ? Regards. Gareth Quote Link to comment Share on other sites More sharing options...
