I was changing oil and filter, and when I was putting the filter cap back, the nut started to slip. It turns out that threads on the studs have worn out, I need to replace them but cant seem to get them out of the body, I tried to use pliers only to make the threads worse.. any suggestions?

Also where can I buy these studs, does anyone has 3 spare to sell?

Looks like it is threaded on each side from the WIKI exploded view:

Maybe try to soak/lubricate them somehow using some of the new motor oil.

It's a long shot - but if there are any useable threads left on the stud you can try putting 2 nuts on and tightening them against each other, then use the 1st one you put on to remove the stud.  Good luck, having similar problems myself at the moment.

Two nuts locked together can work if you have enough threads left, if not I'd go for broke.   :icon_rolleyes:  I'd take some good Vicegrip pliers and clamp them down as tight as possible on a stud and then rap the Vicegrips with a hammer to break the studs loose.

Take a stud to the hardware store and get some capscrews with the same thread and use them to get running.  Order some new studs and put them in next oil change.  You don't want to wear out the threads in the block by continuing to use the capscrews.

two nut trick does not works ... the threads are worn out and the first nut slips :mad:.... let me try the plier technique..

Vice grips work great to remove nuts an bolts, sometimes better then an actual wrench/socket.

I actually done have the vice grip pliers and thinking of buying one, which one should I go for these small studs?

you can buy the studs at most bike shops.  I broke a bolt off a few months ago and had to get them drilled out.  I bought the new bolts at bikebandit for less than $1 each.

Thanks you guys, once again GStwins to rescue.  :cheers:

the locking pliers did the job efficiently... boy these have some grip!!

"SCORE!"  :thumb:

There are tools available specificaly for removing studs, they dont stretch threads or damage shanks. They are expensive to buy but the cheaper option is to make friends with someone who has a set

^^ always read the fine print  :laugh: :laugh:

Go buy some PB BLASTER. Spray the studs liberally. It creeps, so don't get it in the motor !

Put a torch on the studs (DONT MAKE IT RED HOT) before applying the PB BLASTER. Let the bolt cool first ;)

Give the end of the stud a couple firm hits with a hammer while trying to turn the stud out with a heavy pair of vice grips. You're trying to vibrate the studs, not kill them ;)

If it all fails, heat them with the torche again, just till they smoke off the oil/PBBLASTER and then do the vice grips with hammer deal again.

Good luck :)

When you install the new studs, put a ball bearing in before you screw in the studs. It prevents bottoming the studs on the threads. Torque them properly. Riiiiiiiide.

the vice grips took em out for him  but the hammer thing might have helped a little  :thumb:
