Stuck chainring bolt
Hey guys, I have a stuck chainring bolt that I am out of ideas on how to remove. Ive tried WD-40 and then liquid wrench but this one wont budge. The other four came out fine but this one's being a little bitch. Any ideas? This is on a Sugino GC crank arm and a Tuf-Neck chainring so don't want to go all Hulk on it...

Re: Stuck chainring bolt
Soak it in Blaster for a fairly long time (mabye a couple hours) and it should some loose. Otherwise you might have to drill it

Blow torch.
Apply heat to the chainring bolt then remove. Sometimes even giving the allen key a smack with something when it is inserted into the female portion of the chainring bolt helps. That will loosen the grip a bit after some heat is applied. It should pop out easily enough.
A proper chainring bolt wrench helps too so you don't carve the chainring bolt up with a screwdriver.

Re: Stuck chainring bolt
Have you used the proper chainring bolt tool to gain leverage on the pictured back side?

Re: Stuck chainring bolt
using a torch and paraffin wax is an old-man trick that has worked for me everytime. (heat the fastener, wax melts, wix down the threads,) I used it when pulling studs out of a buddy's 39 flathead motor, when PB Blaster didnt cut it (which was a surprise)

Re: Stuck chainring bolt
Thanks guys, lbs for this one so I can get it done and get these Sugino cranks listed for sale, but also ordered a Park wrench off the Bay for $4. Hopefully no more of these issues in the future.
Love you guys! In a completely hetero,not sitting next to you at the movies and no you can't share my f-ing popcorn sorta way...
