ok this may sound stupid but iv got issues gettn some flywheel bolts undone
I used a rattle gun on them and managed to get 5 out of 8 undone the other 3 just rounded the edge. looking at them they have been stuck in with what looks like blue locktite.
As the heads on these 3 rnt damaged badly i want to get them out without to much drama, but they will all be replaced in the end anyways.
Is there any advice or tricks out there
Cheers guys

tip #1. never use a rattle gun.
tip #2. if suspect rounding, replace with new bolt
tip #3 Use a ring spanner and put the palm of your hand over the ring over the bolt and apply lots of pressure.
with your other hand, hit the other end of the ring spanner with a rubber mallet anticlockwise.
to win the three still to be undone, you will have to retighten the other 5 again, and go for the difficult 3 first, and the easy five second

It is highly recommended not to re-use flywheel bolts. Your Holden dealer and Repco have new ones. Cheers, Pete. Old Holdens never die, they just go faster. Edited by user Thursday, 18 June 2009 2:30:50 AM(UTC)

the usual suspect is the socket spanner has worn at the end. if the spanner appears not tight enough grind off about 1/8" from the tip this allows the unworn inner section to be used.
I have reused flywheel bolts dozens of times (not the same ones) and not had a problem.
one tip though is if the bolt head appears loose fit when removing do not refit it.

hey kraul
i will stick my experiences in getting bolts out.
hammer and chisel is good alot of the time, but i have in the past torn the head of a bolt doing this.
i always get the grinder out, and very carefully with unbelievable skil of a surgeon, cut fresh sides on the bolt, leaving as much of the bolt head intact as possible.
hope this helps/
cheers
bcb
it was but yesterday, i thought myself a fragment, quivering without rythum in the sphere of life.
now i know i am the sphere, and all of life quivers in rythmic fragments, within me!

Use a 6 sided impact socket if you have one.
As mentioned above, grind the tapered lead of the end of the socket so it gets maximum grip on whats left of your bolt head.
Also as mentioned above, refit the other bolts and give the stubborn bolts a smack flat on their heads to "bounce" them in their threads and mount faces.

locktite wont hurt. to loosen it apply heat from something like a blowtorch the locktite will burn off.
but if the bolt is torqued properly it should (ha) not come loose.
once you cut the head off the bolt the pressure on the threads will be removed and the rest of the bolt will come out easily. as long as it is not rusted or held in by locktite.
never apply oil to a bolt that is meant to be dry, it will tighten too much and you risk breaking it. clean the threads thoroughly with a wire brush then refit.
