Engine assembly

Hi,

Do you need the directions for replacing the crankshaft, bearing, and so on or the directions for removal of the engine as well?

Regardless, when you remove the crankshaft, the timing chain needs to be removed first and the transmission will also need to be removed.

When I look up "engine disassembly and assembly," it provides two separate sections. I am going to provide section 2 which seems to be more related to the crankshaft, timing chain, rod bearing, crank bearings, and so on. It does include removal of the cylinder heads and pistons, but if you are not doing them, skip over that section.

There are a lot of steps to this, so don't be overwhelmed. Also, it would be much easier with the engine fully removed from the vehicle.

Let me know if this helps or if you have other questions.

Take care,

Joe

See pics below. Note: This is section 2 of 2 disassembly and 1 of 2 reassembly.

I already disassembled the entire engine, heads and all. I had the block honed and decked and now they are working on the heads. I have the short block back now so while i wait I figured I should put the bottom end back together. So thank you very much for the instructions. They are very much appreciated.

Hi,

You are very welcome. When you said bottom end, I wasn't sure exactly what all was needed. I'm glad that helped.

If you need the other information, let me know. There are a ton of pics that go along with the directions, so they may help you.

Take care,

Joe

Two of the bearings are chipped. That means I have to get new ones, right?

They were brand new. First one is on the block second one is on the cap.

Hi,

I wouldn't use them. Can you tell the place you got them from they were damaged when you opened the box?

Joe

I wish I could, but that would be dishonest. I dropped them. I have to pay for new ones, but at least now I know that I need to be 100 percent prepared first by having everything laid out and within reaching distance so I don't drop anything trying to find the assembly lube.

Hi,

Based on your response, I know I would like you. LOL. There aren't too many people like you anymore.

Let me know what I can do to help on my end.

Take care,

Joe

Thank you, I appreciate the kind words. Sorry for the late response. My neighbor came and drunkenly tried to install my pistons while I was asleep and of course scratched everything and installed them with no oil in the wrong spots with some facing the wrong way. so I had to start all over and purchase everything all over again. I just installed my pistons. For the connecting rods I can reuse them if I change the bolts and nuts right? And for the balances shaft will I need new bearings or just a whole new balance shaft? Also, are there any other parts or bolts that cannot be reused?

I just spoke to the Ford parts department and they said I’d have to buy a balance shaft as a whole. The bearings don’t come separate apparently. $523.00. Is a new one necessary? The bearings are pretty worn, but I can’t afford that anytime soon.

They are correct. That is the only way they are sold.

Yes, I would replace it.

Roy

I found some online. Can I just put them on instead of buying a whole new assembly.

Yes, you can but you would need to disassemble the engine completely to gain access. Joe posted the procedure for removing the engine for you.

If you have it this far apart, you should replace all the bearings, crankshaft, and pistons.

Basically, you will be rebuilding the entire engine. It usually costs more to do this than buy a complete engine.

Roy

I’m currently on the rebuilding part. I’ve already taken my engine apart and already replaced literally everything under my hood except for the hoses which I will order soon. Because of all of the parts that I bought, I cannot afford to pay $523.00 for a new balance shaft assembly. so I just wanted to make sure that replacing just the bearings wouldn’t ruin anything.

You need the entire unit as an assembly.

By just replacing the bearing, the clearance may be wrong resulting in low oil pressure from the excessive clearance between the bearing and the shaft.

Roy

Darn, that’s a bummer. Okay, thank you very much.

Can’t I just check the bearing clearance with plastiguage to see if maybe it would be fine as is? If so, how would I find the those specifications for my engine? I have looked online and in my Haynes manual, but I don’t see those specs anywhere.

Hi,

First, yes I can help you with the specifications. I attached them below. Let me know if that is what you are looking for.

And thanks, Roy, for helping while I was out.

Let me know if this helps or if you need something different.

Take care,

Joe

See pic below.

Yes, you can but you also need to use a micrometer to be sure the shaft is perfectly round. If it is out of round, it must be replaced.

Roy

Thank you, but I need the specs for the clearance of the small balance shaft bearings.

Joe attached them with his last posting. The attachment contains all the information for you.

Roy

Thank you.

Have you been able to make progress? I'm interested in knowing.

Also, let us know if we can help.

Take care,

Joe

Slight progress, but then I found out my connecting rod bolts were pressed in. So I had to remove the pistons and take them to a shop. I got them back only to find out I need a special tool to replace the auxiliary shaft bearings. Do you know what tool that is and if I can replace them myself?

Hi, Ariana.

A balance shaft is only used on the 4.0L SOHC engines on the 4wd models. See the pics below. Are you referring to something different?

Let me know. Also, let me know how things are going with the rebuild. I'm interested in knowing.

Joe

A tool is a camshaft-bearing tool. It has different adapters on it for removing the bearings and installing them.

Roy

No that is the one I’m referring to. I’ll attach an image.

And okay, thank you. That cam tool will work for the auxiliary shaft bearings too?

Hi,

Yes, the same tool should take care of that as well. Keep me in the loop. I'm really interested in knowing your progress.

Also, let me know if I can help.

Take care,

Joe

As Joe said, the tool I attached and one you have does the same thing. Make sure you put them in the correct position. There should be marks on the bearings such as 1,2 or 3.

Roy

Okay, I ordered the bearings and the tool. They will both arrive on September 1st. My book says not to put oil or assembly lube on the back side of bearings, but I was wondering if you could tell me why. Also, does it matter if I use oil or assembly lube? If so, in which places do I use oil and in which places do I use assembly lube?

Never any oil on the back side of the bearing.

Use assembly lube on the bearing surface.

Roy

Okay I won’t, but why not? What does the oil do? If there’s already a hole for the oil to pass through won’t it get in there somehow anyway? What damage is caused from oil getting on the back of the bearings?

The hole is for oil to lube the bearing while running.

If you put oil on the back, it may damage the bearing installing it. It requires installation dry in the back.

Roy

I had my bolts separated but I am also in the process of fixing my house up (painting, skim coating drywall, etc.) and in all of that my bolts have gotten mixed up because I wasn’t being careful. Is there a way for me to find out which bolts go to which bolt hole? Only thing I can think of is laying them out and matching them up and if there are 5 that fit in a place that has 5 bolt holes then put them there. The bolt holes that are left over I was going to call the parts department at the Ford dealership and ask what the part numbers are for those bolts and look them up and match them up with the bolts that are left over and put them in the appropriate bolt hole. That will take a while though so I’m hoping there is an easier way.

The bolts are not marked so there is no way to identify the exact location of the bolts.

Can you attach some pictures of the bolts for me to see?

Roy

There are a lot. I know where some of them go. Right now I am trying to figure out which two are the balance shaft tensioner bolts.

I found a picture of the tensioner but it does not list the size or length of the bolts.

I would try the 2 bolts by your right foot behind the pile of bolts. They look like the size.

Roy

That picture is the oil pump. I mean the bolts for this I think i found them though.

Although I did have a question about my old pump. There is a small crack where the screw goes in but if I put some sort of sealant on it will it be fine or will I have an oil leak?

You need to replace it. The crack is no good and could cause leaks or future problems.

You are this far, so replace it now to be sure there are no future issues.
