i hear alot of people on here talking about jbweld to fix cracks on the crankcase that the problem with my quad i got permapoxy a multi metal epoxy is it just as good or should i get jb weld and sent this back to the store for what their sit says the both hold up to the same 4500psi but jb weld is good to 500f the stuff i got good to 300f
so how hot does the case get? my crack i by the front dive gear so everone knows

 

bottom end gets around the 200s.

 

JB weld is usially better for sealing purposes, such as what you need it for. It mixes thinner than most epoxies and definetly thinner than any putty you may see that makes similar claims. Plus JB weld has proven to be resistant to most chemicals and people have used it to repair cases for years. Just make sure you clean the heck out of the area you are repairing, and use a heat lamp or hair drier to warm everything up and thin it out good.

 

some reason the crack stoped leaking i was riding out in the snow a few hourago with nothing over the crack for about a 2hours no leaks

 

i just checked it out their was no oil in it. i must be the very lucky the crack is bigger then i thought goes form the starter nuder the front sprocket all the way to the right case. would any of these epoxys hold up to a crack that big

 

would putting on another layer on the first help make it stronger

 

Yes it will. Good idea too, as you want to not only fill the crack but keep it from growing.

dude... its only a temp fix... Just spring for the new case, check e bay I am sure they cant be too much... ... I keep a small amount of jb weld on my quad so it that happens I am safe, but I had it happen a long time ago to my 200x, used JB weld to fill a hole caused by a rock worked for the rest of the weekend but wouldnt use as perm fix.

 

why not just bring it to welder to get fixed?

 

a temp fix is all i need if any of you cheacked my profile im putting a sportsbike engnie between the rails in about 2-3 months so if i ride once a week for 3-6 hours 6x4=24hours 24x3=72. i rode that about that much for the past 2-3 months wow im shock i put over 170 hours on my ride in less then 2 year i had my quad for one and a half years.144 hours in 4 months. i may have it welded and put jb weld next week.
