Motor mount bolt stuck! - Snowmobile Forum: Your #1 Snowmobile Forum

letitsnow · 07-25-2006, 06:20 PM

i have to remove the motor from my bike because it won't shift out of first and i want to do a top end. the swingarm/motor mount bolt is aluminum corrosion seized in there and you can't get any oil in there either. i've already tried to beat it out with a big hammer, no luck.
any ideas on how to get it out?

Heat it with a good torch.

me and my dad got it about 3/4" out by laying the bike over and beating the crap out of it with a 5lb hammer, now its in there and i don't have anything that will fit through the hole and take the abuse needed to move the thing. i think i'll go and scavenge through my old bike parts tomarrow and try to find an axle, that should take some pounding.

torch it, wd-40, repeat if needed. works wonders. the heat will expand it, then the wd-40 might squeeze in. if u dont have a torch, buy a lot of lighters, lol and maybe some steriods. it will come out with heat, just takes time. if u dont have one, call up a car mechanic and see if u can rent his.

sounds if your 3/4" out then spray the heck outta of it with Break Away spray beat it back in and keep working back and forth you'll probably gain each time till it loosens, Break away is good stuff as is WD 40,

Craftsman socket extension bars are always good for drift punches. If the get F'd up, just take it back to Sear's for a new one!

Just light the wd-40 on fire and use the spray can as a torch. Two birds with one stone

i've got torches, what should i use oxy-acetelene or mapp. j/k.
i used an old axle as a drift, i'm deffinetly gonna need a new bolt. i've been using Kroil oil, i've never not gotten a bolt out using this stuff on steel, dunno how it works on aluminum.
i'm gonna go try the torch now.

i got it out, i found an even bigger hammer than the one i was using.

Persistance and cussing = rusted parts seperated.

see, a bigger hammer acts like bigger muscles. if you could swing the other hammer harder it would hit with the same force as the bigger one.

As the saying goes,
" If it don't go, don't force it, get a bigger hammer."
