Triple Tree problem


Recommended Posts

So I finally decided to replace my steering bearings…started loosening the (fork tube) pinch bolts on the top and bottom of the triple tree…I had no problem with the top pinch bolts, and really had no issue with one of pinch bolts on the bottom (the lower of the two on each side), but the upper Allen bolts ON BOTH SIDES  are just so tight, I’ve stripped one out and fear I’ll strip the other out if wrench on it any more than I have. 
I thought maybe I could just remove the main steering nut and slide the lower triple tree out (still attached to the fork tube), but I seem to remember there is a small clip on the upper triple tree that needs to be removed before the tubes will slide out.

Any ideas? I’ve used an impact, I’ve tried a long lever (with a constant even torque), I’ve used penetrating oil….although I haven’t tried heat (concerned I might melt fork seals).

Okay, so you have me a bit confused. You mention you have no problem with the top pinch bolts and then you talk about the upper Allen bolts that you are having trouble with. For me it's confusing.

There is a ciriclip that goes around the fork tube to prevent the tube from sliding up too far, so if you are wanting to remove the lower triple tree with tubes attached, I think that would be possible.

BTW, the torque on the pinch bolts is only 12lb if I remember correctly.

Thanks for the response Carl,

there are 2 pinch bolts on the upper tree and the lower tree. I was able to loosen the 2 bolts on the upper tree. There are 2 bolts on the lower tree (a lower bolt and an upper bolt), I am having trouble with the upper bolt on the lower tree…both sides.

Then you should be able to loosen the upper tree and slide the whole works down and out. There will be nothing holding the tubes in place. You will have to be careful to lower them at the same rate or they will cause each other to bind. You will also have to remove the brake calipers and the fork brace that is between the forks at the fender level, and the fender as well, and oh,the front wheel. 😊

Get a torx bit slightly larger than the socket hole in bolt. Grind the end of it flat so you end up with sharp corners. Grind lightly so you don't heat the end of the bit or keep cool with water. Now drive it into the end of the bolt. The now sharp corners will cut matching grooves in head and as well the tapping action of driving the bit in will help break the threads loose. Put a socket or wrench, on the bit once you have driven ti all the way in and carefully and gentle wiggle back and forth until you feel start to move. Once it starts to move continue the back and forth movement from stopping point to stopping point until it fully loosens and you can easily back the bolt all the way out.  If you have not rounded the hole out yet, try  putting the proper fitting allen bit in the bolt  and wack it a few times with a hammer like your trying to drive it deeper and than follow the back and forth motion described above. Avoid using too much force as you work it back and forth.

I always wack steel bolts in aluminum if they seem the least bit stuck. They’ll back right out 99% of the time.

Hand impacts with a real good tight fitting impact grade, 6 point socket work best for this. Also try retighening the bolt that you have broken loose to take some pressure off if you have two bolts pinching the same location. I have also used the ol hitting the bolt side at an angle with a punch to break it loose very effective. I have even used that method very successfully on the smallest of screws. Especially when I have a steel bolt/screw threaded into aluminum.

I have as well even have one with a handle cut from an old adjustable welded to the side so it wont spin in my hand when I use it to break loose bolts up to 1/2 " using a small mallet.

Sorry for the absence, life gets in the way sometimes.

Cowpuc wins the prize! Hand impact won out (was also the first thing I tried). I retightened the lower of the two bolts and gave the upper bolts a couple medium tappy-taps to tighten, then changed direction to loosen and let loose with a 3lb maul. Came right undone (even on the stripped out one)!Thanks guys!

 

As a side note my bearings had some notchyness in there (I’m certain they were OE), and after pulling them out, the grease was like glue. Also, those races are fighting me every step of the way (can gain almost zero purchase, even with that little cutout they give you)…I’ve gone the destructive route and started cutting them with a dremel.

I’ll update when I have more.

thanks again
