1) I'm trying to rig up a crank pulley holder for a timing belt change for my bro's Camry. Can I use Jbweld as a threadlocker if I need the threaded pipe nipple to stay permanently affixed?



2) My bolt on my diff is stripped and leaking. Is there something less permanent than Jbweld that can seal up the stripped bolt?


Thanks.

 

nvm...

 

If your crank pully thing is going to be torqued a lot, the JB might not hold. Only one way to find out.

For the diff bolt, why not get another bolt? IF you mean the threaded housing is stripped, then

if it is not stripped too bad (bolt is loose and slutty in the hole)

then you can use white permatex high temp sealant.

 

Red vs. Blue.

I think what you want is blue loctite. Good hold, but will come apart if you use some force. Red loctite is more permanent.

 

I love it at work when somebody comes to me and says, "somebody put locktite on these threads and the allen key rounded out the bolt head."
No locktite is permanent.
Throw some heat on the surrounding thread area, and it "cancels out the locktite" so to say. I can't tell you how many times people have broken off drill bits or easy outs in bolts because the threads were locktited in place, and I still was able to drill out the broken bit or whatever was in there, and heat/ extract the stripped bolt without damaging the threads.
If you want your threads to never move again ever, and you want to use an epoxy...JB weld.

 

If I interpret correctly, we want the threaded pipe nipple (the part that the wrench is on) to stay permanently attached to the flange, yes?

First off, forget that Permatex thread sealant. That stuff is just the liquid version of teflon tape. It's for sealing against leaks, not locking stuff together. "Lubricates threads for easy assembly and disassembly."


My vote would be for either JB Weld or something like Scotchweld DP420. A 2-part epoxy that'll fill all the little imperfections and really bind the pieces together like true love. Red or Blue might work, but on threads this coarse, I question what total percentage of the surface area they'll wind up securing.

 

Drill a hole in the flange perpendicular to the threads. Stick a nail/dowel/cotter pin in the hole. It will not back out, but may be removed if you need to.

 

I am a true believer in Jb weld bukkake, it has saved me many, many, many times and is still holding in very hot, very vibrating, very slippery areas (kinky)

 

Yeah, that's probably the best solution I've seen so far.

 

I didnt say absolutely permanent, you will never get them apart. I said it holds more firmly then blue.
