tri-z stripped peg bolt holes

[VenomRS4]

My Z's bolt holes for the pegs are stripped really bad. How can I fix this? I was thinking about putting JB Weld in the hole and then threading the bolt. Would this work?

[chris200x]

Very common problem with the Z. I ended up swapping frames. Is it on the kicker side? I guess if you wanted to you could always just weld the peg on or a new bolt inside. :rolleyes: MAybe a helicoil? :wondering

I'm intrested to know what a permanent fix is as well. I really wish someone would offer some aftermarket pegs for the Tri Z.

i know on my triz, the previous owner, brrcuda, reatpped the threads to a larger SAE size.

Drill all the way through the frame and nut it on the other side. Jb weld or welding on a stud anything like that wont hold for very long. Ive done it on many quads and 350x's. Dono if its the same for the Z's

I've never personally had this problem, thank god, but it does seem to be a very common problem. I have wondered if the threads were tapped as best as possible just to catch a stud. Similar to a head or cylinder stud, just bigger. Run it in, until it gently bottoms on actual frame tube (which is whats behind hole) and then have it carefully tig or mig welded. The studs would have no reason to ever be removed and your location is correct as well. Then you simply slide peg over the stud and use a quality thick washer and hardened lock nut. I'm sure this would work, and it allows quick removal of peg if need be. I have a place near me called fastenall, and they have every nut, bolt, stud, ect known to man. Sae or metric. This way you can keep you bike all metric with oem size fastners. Remember this is just an idea, but dont see why it wouldn't work. Hell, studs could even be used even if your threads were in good shape, just wouldn't need to weld them, and may just prevent future damage from overtightening, or bolt loostening up and then slowly mangling thread from vibration and weight stress.

Once you've maxed out the nut with re-tapping or the nut snaps off from the inside the way to fix it is cut the weld on the cap that covers the frame there and has the nuts for the mounting bolts welded to the inside of it. I use a cut-off wheel. then cut the old nuts off the end cap and re-weld new "better" nuts the the inside of the frame cap. Now re-weld cap to frame. That's how I do it.

Coles got the idea im getting at.

My Warrior had the same problem. Had a guy at a machine shop cut the old nut out, then he took a 1'' steel dowel on a lathe, tapped it, then welded it into the frame.

Whatever you do dont weld the pegs. Mine were welded when I got it, just imagine having to pull the dam motor everytime you go in the case!

metric Helicoil and red locktite

buy a whole pack with the tap and installer you will need them:lol:

I have one thats welded on SOLID... diss-connect the foot pedal and the clutch cover comes off,,,:p

And yeah Raffa is right. the helicoil works fine.Still goin a year later Brian:D

I would carefully grind off that piece that holds the threads with a dremel and a 3" cutoff wheel. Then I would take a piece of cold rolled steel, thread it in a lathe, and reweld it to the back of the piece you ground off. Then reweld that back to the frame. Lots of times those things are barely tack welded in there and they rust, turn, seize and snap off.

When the SX did it, I made a whole new insert on a lathe about 1.5" long and threaded it. Then I drilled a hole in the frame tube and that allowed me to weld both the front side and the back side of it securely. It never failed again and I jumped that heavy ATC allot.


NEVER EVER HELICOIL, JB WELD OR EPOXY A FOOTPEG HOLDING THREAD.

[Bryan Raffa]

I have done it many times..and have yet to have one fail.. it must be done correctly!

[Dirtcrasher]

I'm a HUGE fan of helicoils, just not in a "structural application".

The fact is that the strength in a footpeg mount is not in the threads but rather in the shoulder of the surface the footpeg mounts up against.
And, if it is tight whether it be helicoiled, threaded insert, drilled out etc etc, it can work. I personally just don't want to to risk landing a jump, having something fail and my foot getting dragged under the rear tire.

I used a 12mm thread 1.25 pitch tap. My threads were spinning in OK but would loosen up during ride time and had some slack. They weren't as bad as some i have seen on here. So i drilled it and retapped and put 19mm head bolts with lock washers. Never had an issue since - 3 years of hard riding. I did have to cut the bolt to make it shallow enough to not hit frame.

My other Z is still on original threads.

Gardserts maybe, little more beef than a heli coil. http://www.gardspecialists.com/

[VenomRS4]

man, id like to fix this without spending an arm and a leg. I dont have a welder and I dont have any welding skills. So I think I may just get a larger size bolt.

hey, next size up metric is the cheapest way to go. most auto parts stores have the tap and bolts to match.

Definitely the way to go for the first few times. After you've gone too big that's when I'd recomend doing it the way I described earlier, if you have the equipment and some experience. ;)

[tri-z250MN]

my threads srtipped out so i took a grinder to it and got 2 bolts and nuts (grade 8 of corse) and hammered the nut into the frame and welded it. for best results use highest heat setting possible but be carefull. tried jb weld but it pretty much fell out as soon as i stood on it

[ceaserthethird]

Jb weld is Gay !

Heli-coil worked for me 2 years and still going ...
