Engine swapping and general refreshing

[72maverick]

Where did you find the arp bolt

 

[72maverick]

It was the the same crank bolt from the engine

I have had luck with this type of situation by turning the bolt counter clockwise and pulling out at the same time...Try prying on the washer with a screwdriver wile turning...A little creep lube will also help.

I tried it, but maybe with somebody else I can get it. The washer is in there like nobodys business. No wiggle in it

I have had luck severial times doing as drag-200stang said in his above post, yes great idea if you can get that extra helper. Best of luck Edited

If your going to dril then look for a left hand twist drill.
The idea behind the slide hammer vice grips it to put some pull on it and try to get the threads to bite so you can use a socket to get it out.
Your not going to be able to just pull it out unless the bolt is way wrong and very undersized

 

[72maverick]

Prying yields no rusults...

Might have to drill. Would left vs right make a huge difference in the case? I guess there are still threads since the bolt isn't coming out. Do the normal stock revers drill bits.


The bolt doesn't care which way I rotate it, it behaves the same

Yes this ^

Try taking a small tool and grind a sharp edged grove in the bolt head circumference so you can pry harder with maybe a fulcrum under pry tool while turning.

 

[72maverick]

I was thinking a cut off dremel disc on the side edge of the bolt head to get a pry under it and then start cranking. Worse case, I damage the head and have to drill anyway

 

[72maverick]

Used a brake adjust and got it off. Need to clean the threads. Good call on the too short of a bolt

 

[Econoline]

Awesome

Brake adjuster sounds like the perfect tool to get in there and pry while you turn.

Are the threads gone on the bolt or the bore? If you can get a longer bolt in there and it was the bolt that mostly gave way I bet it will be all good. Chase those threads real good and blow it out.

is the 'stack-a-shive' on the back when he should have put it on the front?

 

[72maverick]

Only the first 3 threads were engaged by the looks of it. I will chase them and clean it. I ordered the 2 inch bolt recommend above

 

[bubba22349]

Glad that you got it out with out much trouble. The 2 inch bolt might not be long if the orginanal 1 3/4 inch bolt was only engaging 3 threads, the extra 1/4 inch is only going to give you another 4 treads or so. Measure how thick the add on pulleys is you might need it be much longer. Also measure how far the the threads go into the crankshaft you might be able to use a 3 inch long bolt. Best of luck

 

[72maverick]

Also, is the bolt for the 200 5/8 or 9/16x18 like mentioned above ?

 

[72maverick]

My book says m12x1.5
Should I be looking for an M12x3 or whatever measured length I get?

I'm getting confused on this bolt size now.

 

[drag-200stang]

You are on the wrong page that is not a for 200 I six.
I will check that bolt after I finish breakfast.
I measure 9/16''-18 and the torque for it is 85- 100 ft-lbs....Grade 8 would be best...Get as much thread engagement as possible with out bottoming out when torqued.
Make sure that the washer is sitting flat on the pulley,it looks too large in the pic?...If you use a different washer it must be stout like the one you have...Can you show us a pic of the assembly, with the bolt out.

 

[72maverick]

I have a long bolt with a smaller washer from my last block. It's 2 inch bolt.

Here's the only photo I have on hand. I'll trust your measuring. That was a photo my dad sent over, I don't have the manuals on me at the moment

 

[drag-200stang]

Just a reminder when chasing out the bolt hole just make sure you are on tract with your chase or tap, go a little and check your work ,you can remove your good threads if your not careful.
The factory size is 9/16''- 18, but of course who knows what has been done to it before you owned it. if the threads are shot and will not hold torque then you may have to up size.
