    hiya im looking for some advice on how i can get the bottom pulley off my Civic esi. I've tried everything i can think off air gun, electric snap on gun, heating it up and hanging off it with a bar and scaffold bar. can't think of anything else :Frown: the main problem i think im having is stopping the pulley from moving as i can't seem to find any holes on the pulley to lock it off, so I've had to have it in gear and stand on the breaks.


    please help :Smile:


    cheers toby

    big breaker bar and socket, 8ft scaffold bar, get someone to hold the bar and hitt it with a hammer. Put some heat into the pulley first, not the bolt (will make the pulley expand off the bolt)


    The sudden shock from the hammer normally cracks if off. Has worked with all the stubborn bolts I've had to deal with.

    there is a small hole by the gearbox, where you can see the flywheel. jam the flywheel and try to crack the bolt.. it works on my one and on my mates B16.. if not try his option(ALLTIME-Industries).. hope you get it off mate:Wink:

    On nissan engines i know a lot of people use a chain to wrap round the pulley and then crack it off with a breaker bar or air gun.


    Not sure if its some sort of special chain or just a normal piece of chain...

    dude you'll notice on the crank pulley there is a hexagonal hole for a special tool to lock off the crank while you undo the bolt. you MAY be able to get if off without but I've always failed using basic hand tools and breaker bars without using the locking tool.

    thanks all for you help :Smile:


    managed to get in undone today made my own little tool lol


    got a 46 mm nut and a bit of steel welded them together and wedged it on the floor and it held the pulley. ended up snapping 3 extension bars though :0


    thanks again for all your advice

    I done it as follows: ( Dunno if i'd recomend doing it though)


    Take your largest breaker bar and socket. Apply these to the bottom pulley bolt.


    Jam the bar against the ground, ask some1 to help you here as it can get a bit crazy.


    Turn the engine over so that the bar stops the nut turning. Unfotunately, as i did not realise, Honda engines turn the wrong way to do this trick. The head of the bolt then sheers off and the shaft can be tapped out using a screw driver.


    Please note this may not work, you may infact be stuck with a sheered bolt in your engine!
