Broke My Dowel Inside My Fork
« on: January 07, 2019, 10:43:17 pm »
I was using a dowel to disassemble my forks. You can drive a 1/2” down down inside the fork tube stop the inside part from spinning while you loosen the 6mm hex on the outside of the for lower. This is a method I found on YouTube and it works well.

However on my second fork the dowel spit as I was driving it and now I only have about 1-1/2” of dowel poking out, and it’s flimsy. It’s well driven in there and I don’t know how I can get it out. Right now my only idea is to wood glue the split portion back onto the dowel and hope to have more purchase that way. Any other ideas would be appreciated.

 Often if you use an impact gun, it will spin right off,.

No #$%*... well, i’ll Try that first thing tomorrow. The heat really helped with the first one, so I guess a little heat and then i’ll Try the impact driver.

Next time, before you uncap and drain the forks, release that screw at that the bottom. Makes life SO MUCH EASIER.

How are you able to release it? Does the pressure from the spring make it possible? I could always slide the spring back in, over the dowel, and try this method.

Yes. The spring and fluid keep enough pressure on the damping rod, that a bit of heat and a quick hit with an impact will more than likely crack that sucker loose. Can be a bit more cumbersome due to the weight of the assembled forks, but a LOT easier with even assembled to knock that bolt loose in my experience...

 The spring holding it is a big helps you can change the fork seals without pulling  the fork tubes out of the triple trees.

Ok, thanks for the tips guys. Tonight first thing I will try is putting the spring and cap back on and then heat and impact driver.

BTW the reason I am doing this job with the forks on the clamps like this is because I don't have a vise so this is the way I can keep them from rolling around while I'm wrenching on them.

Ok but you can leave them on the bikes if it's just seals.  Now is the time to check if they are straight .

I have them off to install emulators, and while I'm there I plan to refinish the fork lowers. So it's a whole overhaul.

That worked great, thanks for the tip. I think the dowel was supposed to be a last resort but I misinterpreted the video and thought it was the first method to try.
