I am new here, so hello everyone. I have an 2002 explorer with a 4.6, and I tried to take off the cranckshaft pulley and the bolt rounded off. I tried to use a "bolt grip" and it broke it. I'm pulling the motor but I need the timing cover, cause the other motor I bought came out of a 2000 f150 and the timing cover is different. I am a women and doing this on my own, my husband is working out of town and cant be here to help. Can some one help me with this problem that I have. Thanks for reading. Andrae

 

Do you have an impact gun? I would pound the next size smaller socket on it and hit it with a good impact.. If you dont have one borrow/rent one. Gotta be a good one cheap one wont budge it.

 

the size is 18mm. As well our explorer motor is a pi motor and the f150 is non pi. If worse comes to worst you can weld a cheap socket on the head of the bolt and get it off that way.

 

Yea, impact gun. Or weld the wrench that fits it onto the rounded nut since you have the engine out. Or if you dont have either option. Find a standard size wrench or metric that is smaller but close to it and pound it on. Then give it a good smack with the hammer. They need a quick blunt hit to break loose.

OOps, someone beat me to the weld on option

 

Also don't use 12 point sockets. If you get a 6 point it still may work.

 

Ford LOVES to use Loctite. (guess that's a good thing, at least parts aren't falling off like a Dodge) Wonder if they Loctited the bolt? I've seen 'em Loctited on other cars. When the bolt is conventional threads they need to be Loctited AND pretty darned tight. Impact and 6 point is definitely the way to go on a crank bolt. My brother got a 3/4 in impact to get the CS bolt off on his Toyota Highlander when he couldn't budge it by hand. OBVIOUSLY, problem solved!

 

I have a 600 lb impact gun and a welder, so i will try that treat after i get off from work today. If the 600 lb gun wont work i will borrow a friends 1200 lb gun. thanks for the tips.

 

Go Girl !!

 

Ma'm you're gonna take that timing chain cover off without evern removing the bolts with that thing!

 

i will do what ever it takes to get that SOB!!!! off lol. I have another question, you will mit think this is stupid. What is the difference between a PI and a non PI motor.

 

PI = Power improved heads.

 

PI is a different shaped intake port, wheras the NPI is more of an oval. Also PI has COPS or Coil over plugs. The NPI has coil packs. those are a few differences.

 

What kind of problems will I run into with putting in a 4.6 out of a 2000 F150, both are a vin code "W". The 2000 motor is a cast iron block and my 2002 explorer is a aluminum block. I'm using the heads, intake, and timing cover off the '02 motor. Just want a heads up on what to expect. This is the frist motor swap for me. according to the PI and NPI on the intakes both motors must be a PI because both has the coil over plugs.

 

Look on the heads of the f150 around the exhaust ports, if it is a pi motor (on the f150 motor) it will have PI right by the casting number. If the motor from the f150 is a pi I wouldn't waste your time or money swapping the heads over. depending on what happened to your explorer motor it may still be worth some money. Those aluminum blocks are/were very sought after

 

Your 2000 truck should be NPI (non Power improved) the 2002 Explorer is PI (power improved). Are you sure the engine wasn't just built in 2000 but is a 2001 MY? The W code is for Romeo build which both are. A(6) code is Windsor build. You can use the truck heads on the Explorer aluminum block or on the cast iron block the block doesn't care what heads it gets. But if you install the Exporer heads on the cast iron block you must specify that you will be using the head gaskets on cast iron block not aluminum. The truck and explorer use different head gaskets because one has aluminum heads attached to an aluminum block and one has aluminum heads attached to a castiron block. Different movement between dissimilar metals. Just buy head gaskets for the truck if you mount the heads on the castiron block. Here is a site that shows charts regarding PI vs non PI application. http://mustangboards.com/modular-4-6...vs-non-pi.html Since both engines are Romeo (W) code the front cover and cam covers will interchange. However PI and non PI intakes are not interchangable with PI and non PI cyl heads. PI intake to PI heads or non PI intake to non PI heads only.
