are you talking about the one that's on the engine/tranny? the VERY top one? it was a bitch for me too. try to remove anything that blocks your way. and use a wrench the whole time if you can. also, i'm not sure if it'll help, but try to do that one FIRST.

 

EITHER:

a wrench from the top of the motor,

OR

a 14mm socket, universal, and several long extensions to a large ratchet/impact wrench from below.

The first leaves less room for personal injury except for a knuckle or 2.

The second is usually pretty quick and easy, but universals and sockets tend to go flying when the nut does back off suddenly if using air tools.

 

heh, i used the second one you mentioned.. and i still couldn't get it loose easily. maybe i did it wrong?

 

You, or the person who did the job last before you

 

i tried all of those that you guys have said.. and so far none have worked for me.?? so what now.?...

oh yea. it is that very top hard to reach one.. yea. that one!..

 

What do you mean, what now? Do you want one of us to come do it for you, or what?

You either pull/push/turn harder until it breaks loose, heat it with a torch to get it to release, or cut the ****** off, simple as that. Those are your basic choices, other than leaving it alone or taking it to someone who has more *** to put behind the wrench then you do

 

Not having access to air tools, my son and I did it the hard way with a 24" extension, a universal, and a 6pt 14mm socket. The bolt wouldn't turn no matter how hard we applied pressure so I heated the metal around the bolt with a propane torch. As the metal heats, it expands, and the clearance between the threads increases. The bolt finally gave it up. I did keep a big fire extinguisher close by, and there are wires. etc to avoid. I suppose that this is another "at you own risk" procedure, but it worked this 1 time.

 

I thought the top right one was the one that has the engine hoist hanger on it and just has a nut on the aft end of it. And you just remove the nut if you want to remove the transmission. Worked for me. At least on the motors I've seen....the head is on the fwd side and the nut on the aft side and just the nut is the only thing that has to be removed.

 

hailers> yea, that is true.. it is that one. and yea.. maybe i should try heated it up a bit.. only choice now.. i've push and pull already.. all that stuff.. i've tried universal and extension.. but i'll try heating it up a bit.. and using a impact wrench.. but yea.. my last choice is to just cut the dAng* thing.. off thats true.. but still i don't really wanna harm my FC. but i know sooner or later i will so.. why wait huh.. eheh.. i'll see wassup... but yea. for sure.. i needa try the heating and the impact.. thanks..

If your doing it by hand (wrench) watch out for a sharp piece of metal that comes to a point right above the bolt on the body. Some wise *** engineer put that point in the body to tear our hands up.

Crack it loose with a 14mm wrench that has a offset. Sears sells one thats long enough to get some leverage on it. Then get your 36 "extension(s) and a 14mm universal and back it out from underneath.

 

well, when it was all said and done i wound up "cutting the ****** off"

but if you did do that... what next? just put a nut inplace of the top of the bolt? there is still a good amount of thread that isn't cut off. do you NEED it to be there? i would think not.

 

All that thing is is something to align the trans by when reinstalling it. It is the first thing you should aim for when lifting it back up in there, and helps you hold it in place while wiggling it to line up with everything else. Next, you shoot for the 2 dowel pins, and then you start some bolts and snug the tranny towards the motor.

Without it, it just means itll be a bit harder to realign teh tranny, that's all. I wouldnt worry about it.

 

ASE/L1 Master, X Mazda tech here and as I read this lots of things go throuh my mind , I'm not going there.

 

hey guys!.. guess what!. i finally got the dAng* bolt off.. man. thought it was just gonna take me forever.. but guess not.. but dAng* not badd for a 10-15 years old car.. but of course its. a fc. so its bulit to last.. thats for sure!. but yea. thanks guys for all the ideas and tips!. but i finally just hadda cut the bold off.. and i got the swap done. but yea!. thanks guys...

long extention and a swivel socket, and if its really stripped pull off whatevers in your way at the top of the motor to get a wrench on it, and if its really stripped your gonna have to work from the top, its easier, to me anyway

 

if i remember correctly when i pulled that bolt out of my tranny i did it from underneath the car(had the car on a lift), and yes it was hard to get to, but there was also a pocket in there that seemed like it was made to fit a ratchet and a hand, so that helped me a lot
