Engine swapping and general refreshing

[bubba22349]

Excellent glad you already knew about the trans front pump procedures so that should be fine. Does the crankshaft center bolt have the stock Ford large "thick" flat washer under the center bolt? Can you take a good picture of it and post it?

Here you go

Didn't give it time to load

How many pulley sheaves are on the crankshaft Dampner? This front pulley setup doesn't look right. Did you use a longer center bolt along with that add on front pulley? Edited

 

[72maverick]

I did not.

 

[bubba22349]

Is there another set of pulleys on the dampner or bolted on behind that add on pulley? If you used a bolt that was to short for the Dampner with the add on pulley then your probally right that it's done / striped. In that case you will need to drill it out you might be able to do it in the car if you pull radator and the grille to make enough room to get a drill in there or you could pull the engine out again.

[72maverick]

No, it's just 1 pulley and the dampener

 

[bubba22349]

I think your going to have to drill out the center bolt then.

 

[72maverick]

That's what I was thinking a, just wanted to be sure I'm not missing something before I do. Any idea what replacement bolt and length of the bolt I should use?

Also, any recommendations for the drilling process? I assume start small and slow with a punch if possible.


Any recommendations for cleaning the threads when I'm done? Thank you

it's 1 3/4 inches long for the standard lenght crankshaft bolt it is a fine thread A 200 six that it's a 9/16 X 16 inch Dia. A Ford Service manual if you or someone you know has one should have the info for the add on pulley bolt lenght in the power steering or add on factory air condistion section. You are correct get the bolt accurately center punched and start drilling with a 1/4 inch then go up in size. To clean up the threads after getting the old bolt out you will need a good 9/16 X 18 tap to chase the treads. Best of luck "Edited with the correct 200 six stock bolt size info". Also please note that when you are using the Ford add on pulley (see below link) then you will also need a much longer crankshaft center bolt than the above stock bolt. In searches I haven't been able to find that part number listing, check the Ford service Manuel if you have one.

I looked up the crankshaft bolt a stock bolt with washer (see below link) without the add on crank pulley is 9/16 X 18 and 1 3/4 inch long so with the add on pulley you would need to measure and then add the the thickness of that pulley. Edited

I would think if the bolt isn't broken you might be able to persuade it out without drilling. Maybe slide hammer?

 

[72maverick]

I'm for trying whatever. Wouldn't this destroy any threads left, and would I be able to rethread it?? I assume this pulls on the pulleys, would they be find taking the hit?

 

[bubba22349]

Depends on the amount of damage done. You could maybe install a Heli Coil to repair it if need be.

 

[72maverick]

So I pulled this from my 3 pulley set up, doesn't lookuch bigger than my other.

Do you think a slide hammer/ heli coil will be easier?

Or try drilling then resort to slide hammer?

I assume for the slide hammer to work I need a chicken foot for the pulley? I assume the idea is to rip the bolt out?

Slap, 1/2 turn, slap, 1/2 turn and so on.
A length of the correct pitch thread-all some washers and nuts, make your own.

 

[72maverick]

Will those locks have enough to bite on the bolt head? Can't I use my dampener puller for? Should be similar effect to the slide hammer, right?

Edit: nevermind, I think that will just work against itself.

 

[bubba22349]

Yes that's also the standard lenght bolt for a 200 six its 1 3/4 inch long, when you use the add on pulley the bolt needs to be longer by at least the thickness of the add on pulley plus. See below link is this your add on pulley? https://www.neperformancemustang.com/ca ... ts_id=1691

My guess without having one those pulleys to measure is that the bolt will need to be about 1/2 of an inch or more longer.

In my OPIN I don't think the slide hammer idea can work without doing damage to the crankshaft threads, but maybe they are all ready damaged. The Heli Coil could work or you might be able to drill out and tap to the next size bigger bolt. Good luck Edited

 

[72maverick]

I think I am going to punch it and drill it tomorrow and go from there... Then hunt for the next bolt

 

[drag-200stang]

The bolt size for a 200 is 9/16th. 18 thread...I think that you have the wrong diameter size or probably just too short for the job.
