Well, here is the situation.

Today I was at work (Office Depot). And I saw this dude by computers.. so i went over and guess who it was... Otay. Haha so we got to talking and I was telling him about a 13b i had sitting in my garage that i was trying to get a rebuild going.

The engine came from a 87 Auto NA

My Issue is that I cant get the damn thing open!


I Have tryed to unscrew the bolts and **** that hold it together.

Any Ideas would be great

 

Hmm i did mine on an engine stand. I saw one guy use the engine mounts some how to keep it from moving and had it on the floor with a long breaker bar. I would say have a friend maybe sit on it? Impact gun is kinda easier. Good luck.

edit: Holy **** you work at Office Depot too! Same here in Mount Vernon.

 

Haha I stood on it and my friend and I both stood on it. I weight almost 300 lbs so..


Ya Ihave been at depot for 2 years. what you do there?

 

if u dont have a stand, strap that mother down (i see a red strap on ur bench). your gonna need a way to hold the counterweight other wise its just gonna spin on u.

 

We had a wrench on the other side with a bar on it and it was hitting the ground, 2 guys were standing on the motor aswell. Still nothing. Wouldnt budge.

 

I've been working at Office Depot for 3 yrs and been a computer tech but do everything but copy center.

 

Man i do it all, even Manager **** haha

 

OK...
Bolt one end of a chain to the rear counterweight. Bolt the other end of the chain to the rear cast iron. Now the eshaft is locked in one position.
Since you don't seem to have an engine stand, do the following:

Put the engine on the ground
Pull the oil filler pipe out. Put a pry bar in the oil filler section.
Have your friend sit on the ground on the exhaust side of the engine with his feet against the block. If he can do this and hold the prybar, you're good. If not, just have him use the prybar to hold the engine against the force you're about to exert.

Take that wrench i see in the picture. Put the long 4-5 foot handle from a floor jack over the handle of your wrench.... I hope you see where I'm going.

CRANK THAT BITCH!!!

First off, put the tension bolts back in... [Those ones that go through the whole engine that you tried removing]

The way I always do it: Do as Boost Lee says and chain the counterweight in place.
Then put the engine mounts back on, and [I'll assume you still have the engine hoist] then use more chain or ratcheting tie downs, or even rope and strap the engine down using the top of the engine, the mounts, and the legs of the engine hoist. Now have your friends [2-3] stand on the leg on the side that you're going to be pushing the breaker bar from [so when you push it, it trys to lift engine hoist leg that your friends are on], next slide a long pipe [I use my floor jack handle] over your breaker bar, and press with all of your weight against the end of it.

The socket might come off once or twice if you don't have your pressure angle correct, so be ready to catch yourself.. and when the nut does come loose, it will go very fast, and the socket will fall off again.. check the nut every time you try to see if it worked. once it's loose, it should be easy to get by hand.

I've done this about three times or so.. and I can never seem to get it until I strap the engine down [the engine just isn't big enough to sit on/hold effectively..] This way gives you maximum torque against the engine in both directions. ^_^

GoodLuck!

 

Thanks for the tips, my half bro has an engine stand so im going to try and get one of those. but if not ill try your guys suggestions! Thanks


Says it wont work on an Auto

 

Toss that motor in the dd, run out to Import Auto Repair;

have them buzz it off with their air wrench. They did mine for free (but I tipped the guy a fiver).
Btw, make sure the 19 mm bolt on the other end of the eccentric shaft is free. If not, you might want to get them to take it off, too.
This will work 100%. I would have tried the others but.... no friends.

 

I tried this too... Ended up taking the motor to Les Schwabs and having them break the nut free with an impact. You need a strong impact, I bent/broke a cheapy breaker bar with a 6' pipe on it trying to remove the flywheel nut. Best of luck...

 

lol.. I forgot to mention that, I was using a 1/2" Craftsman breaker bar with a 3/4"[?] adapter for the big socket, and the first time I broke the breaker bar [the little black part that you put the socket on broke clean off]
But I got another [Thanks Craftsman! ] and didn't have any problem the next couple times.

Probably better if you have a breaker bar with the correct size for the socket ^_- [but it will work with the normal size!]

 

if you heat the crank bolt up till it gets red with a propane torch , you can get that front bolt off alot easier.(it has locktite) Take some safety glasses and a blunt chizel to the back nut. A few wacks with a heavy hammer will spin it off. I'm guessing that you won't have to hold anything because it looks like you motor had water in it. Don't get you hopes up about rebuilding it. It sometimes takes 3 or 4 core motors to find enough useable pieces to put one back together.

Oh yea... I forgot about that one too.

Though I was told to only heat it up until it changes color *slightly*

I'd be a little worried about heating it up that much and then chiseling on it, you wouldn't want to damage the threads at all ^_-
