Rattle guns

[John Abbott]

Hi everyone...I have been doing battle with a crankshaft pulley bolt on an old laser here. I have to replace a $19.00 oil seal that sits in the timing cover behind the harmonic balancer. I have removed the starter motor to get access the ring gear on the fly wheel. I made up a gadget that would sit inside and lock into the ringear teeth to stop the motor turning as i tried to undo the bolt. Got a good socket onto it with an extension but couldnt budge it. My questions are ...Is it worth me buying a rattle gun to loosen it? How effective are they? and do you need a big compressor to run one? Your thoughts???

When all  fails, I heat it up with my gas set, as it cools down, you will be able to undo it, ofcourse this applys, only if heat will not damange anything.

Hi bas... have thought about that ,but dont have oxy at all so no go.

johnno can you not put a breaker bar on to the rachet handle? (hollow pipe extention) also if you have one that doesn't rachet ie welded or "breaker" one, just swivels .... there stronger..

put a breaker bar on it  brace it agaisnt the chasis turn the ignison key just click it it will crack the nut this is how we do it in the work shop, just dont start it pull coil lead off first

[John Abbott]

Yep Cords ,,,tried the starter motor trick about 5 times even allowing a bit of a run up before hitting the chassis

Dano...I am using all of the stuff you mentioned. Even smacked the nut with a big heavy hammer.
