Changing main bearings on crankshaft

[@DaShit1124]

You did such a good job on this lighting & all I was really hoping you had more videos & tips for a 4.0 in frame overhaul. Regardless still grateful for this one!.

[@azdakrowflyz5963]

That's very kind of you, That motor had a lot of miles on it when I did this but it ran fine, I pulled the head off and took it to a shop and for a $190. They redid all the valves and guides. And while the top and bottom were off.I pulled the pistons and put new rings on each and honed the cylinders. I think I put another 70,000 miles on it since that. Internal face lift.

What a great simple technique. Right after watching this I have to remove my main bearings and redo the crank. I will probably use this technique. Thanks. I love simple and stupid.

It also helps to clean the crankshaft first, just to be sure no metal shavings, dirt, or debris of any sort is in between the bearings and crankshaft. It’ll sucking doing it all over again in 10,000 mile or less, except the second time you’ll be getting the engine re-honed, new crankshaft, and possibly pistons more than likely. Awesome video though, especially with this particular vehicle.

[@maurizioalfieri602]

Why should it fail?

[@Smashachu]

@@maurizioalfieri602 If your bearings wear it'll leave metal shaving. In reality they just end up back in your oil pan, too heavy to be picked up by the pump. If they don't stop there.. We just hope for the love of god they don't make it to the oil pump. In reality if you just blow some compressed air through the ports you'll clean anything out big enough to do damage.

Then put your filter on and plugs in and you’re good to go. The last part is just so you don’t dry start after fully cleaning the engine out.

[@johng.3740]

I have a 2001 Ford Taurus with 3.0 ohv. I found it easier to take a thin long flat head screwdriver (3mm wide) and lightly tap the old bearing until enough of the other side of the bearing was showing. Some people use a wooden popsicle stick to push out the old bearings, basically any thin piece of material softer than the crankshaft metal could be used, though stiff enough to hold it's shape while hammered lightly. After that I was able to get some of the old bearings out just by rubbing it with my thumb, sometimes turning the crankshaft would turn the bearing and that helped getting it out. Some people use a pair of needle nose pliers to pull on the part of the bearing left showing after tapping them with the screwdriver. Putting in the new bearings was easier, for almost all the bearings I was able to push them in nearly halfway with my thumb then I used the wooden end of a rubber mallet to tap them in all the way.

[@azdakrowflyz5963]

That's a great idea, that would have worked here as well, this is how my grandfather taught me to do it on tractors but I like your style. Thanks for the comment.

How long does this last ?

[@johng.3740]

@@great4ever845 Until the bearings wear down. There may be issues regarding the clearance between the crankshaft and the bearings. The standard approach when it comes to replacing the crankshaft bearings is to remove the crankshaft and measure the mains, if the mains are within spec then use standard thickness bearings. IF the crankshaft mains are worn down, then all the mains are ground down and thicker non standard bearings are used. By taking the shortcut in the video we may be installing standard thickness bearings on a crankshaft that may be worn down, so the problem may go away temporarily.

[@MiracleMitch]

​@@johng.3740But you can still check clearance with plastigage when dry before lubing and torquing. It's only when rolling one in and one out at the same time that the clearance check is often missed. Bolts should be replaced too as modern TTY types are used now.

[@johng.3740]

@@MiracleMitch Thanks for the advice, the Haynes Manual does recommend using plastigage on the crankshaft caps to determine clearance, now that I looked at it, this can be done without removing the crankshaft. I have an OHV Vulcan V6 so I can reuse the crankshaft bolts. I've been driving the vehicle for over a year and the low oil pressure light rarely comes on, I still use slightly thicker oil than that recommended by Haynes. Despite all that the engine works well.

[@johng.3740]

Did you try using a small thin flat head screwdriver to get the bearing started out? Another person used a wooden popsicle stick to get the bearing started out, some people using a flat thin piece of plastic. It helps if all crankshaft bearing caps are loose, it reduces the tightness of the bearing. Once you get the bearing part of the way out you can use needle nose pliers to pull them out all the way

Do you put a oversized bearing or just stock one? Would new bearing help with crankshaft walking? Or is that something else on a 350v8.. thanks great video

[@azdakrowflyz5963]

You want to make sure you put the same size back in, your crank may have been ground in the past which means it's a different size bearing now, remove the old one then go by your new one the same size. Re: crankwalk, one of the bearings is different it will control the crank from moving front to rear. I think that's what you mean when you say crankwalk.

My car has a knocking sound but I know my motor is healthy. I caught it early and it only knocks when I rev it. at idle you would think it’s a normal engine but I think my rod bearings are bad and I’ve seen people drop oil pan and replace them after sanding down the journals. Am I able to gain access to what you have here in this video from under my car ?

[@azdakrowflyz5963]

If you can pull off your oil pan I would think you could, mine is a jeep wrangler and none of the suspension was in the way, I wouldn't sand any of the journals or the throws on the crankshaft, even if it looks a little grooved, unless of course the lead on the bearings is completely gone and it's down to the metal on the bearing, if that is the case then you did not catch it in time. If when you pull the bearings out you see lead and the color of copper you should be good just change them out throw it back together. I wish you the best of luck.

This works great, the mains came out and new ones back in easy. With the exception of the main thrust bearing (center most). I cannot get the upper half of main thrust bearing to go back in. I've checked clearances on the sides and they are ok. (looking for any points that might be causing an interference fit). I went so far as to cut a short piece out of the old main to insure alignment (I tapped this in with a brass punch), then placed the upper thrust bearing on the crank as described in the video. When I rotate the crank, the cotter pin tries to ride underneath the main thrust bearing upper half. Frustrating... Continuing to try this over and over is the defn of insanity. Has any one done this successfully? I realize this is a very tight fit. I tried loosening the other main caps to see if I could get more clearance. Worse case, can I remove the crank with the engine still the truck?

[@azdakrowflyz5963]

That's a great question, there is a tolerance for some movement but you need to use something called a plastic gauge to squeeze in side Your Rod and the throw on the crank, and then you pull it back out and measure it with a micrometer and see if it's within the tolerance, if it's not within the tolerance then I would have the crank ground, and they do that in 10,000th increments (.010) and then you buy the bearing to make up for that difference.

[@MJadeMcGregor]

Okay the book says the thrust washers must be installed in the correct journal clean the back sides of the lower main bearing inserts and lay them in the corresponding location in the main bearing cap make sure the tab on the bearing insert fits the recess in the block or the main bearing cap the upper bearings with the oil holes are installed into the engine block while the lower bearings without the holes are installed in the Caps or bed plate.

This is a carpet cleaning van and runs off a pto. So it runs at a high idle for about an hour at a time equivalent to 50mph. The engine still has run smooth for the last 2 years. The the other day I noticed when I came out, the lifters were ticking. Went away as I got to my next job and the same tick after the next job. I put some Lucas in it and the pressure dropped to 0! So I removed the oil pan and found the pick up tube o ring was flattened and dry rotted. I thought that would solve my problem. I was wrong. So I installed a new oil pump. Pressure came back to the 25 psi but soon as it got to operating temp. It went back to 0 again. Due to covid I don’t have the funds for a new engine. I’m hoping changing the bearings will get the pressure back. But I find it strange the engine sounds smooth with no knock. When I removed the flash pan to where the bearings are, everything looked good. I wiggled them and one dose move side to side but not up and down. I also checked the sending sensor and it is good.

[@azdakrowflyz5963]

No it's a 4.0 straight 6 out of a Jeep,

[@nathansumstine9374]

How do you know what size to replace with? There are a lot of different sizes of under size bearings.

[@azdakrowflyz5963]

That's true, you need to pull one of the Caps off and take it down when you buy a new set they will measure it for you.

[@nathansumstine9374]

Az da krow flyz thank you so much. I really like your video. It will save me the hassle of removing the engine from a vet. That’s a huge pain in the ass.

@@nathansumstine9374 was it lt1 vette?

[@nathansumstine9374]

Johnny Autoflower yes it was. A 1996. The #1 connecting rod baring had spun completely around over itself. Turns out the oil pickup tube fell off the oil pump and was laying on the bottom of the oil pan. Bought the car with a knock knowing it had an issue. Time for a rebuild. Thinking about going with a 383 and what ever cam I can run using stock heads.

@@nathansumstine9374 so was your oil pressure near zero at idle?

[@user-oh5jy7bg4i]

Is it normal that one bearing is a different size to the rest? My bearings on my 3.8L jku has three of the same but it says the last is a different size, this happens to be the one that’s worn and spun. Is this because there was a thin bearing on it??

[@azdakrowflyz5963]

Wow that's a good question, I'm not completely familiar with that motor, Have you already bought the new bearings? And if so have you checked if there's a different one?

[@megamac3898]

But how did you know that this is the right bearing to be changed? Or you r going to change them all ? I like the idea it’s great 😊 thank you

[@azdakrowflyz5963]

The motor ran fine but had 200,k miles on it, I changed all the main bearings and the connecting rod bearings as well. I have 260, 000 miles on it now and it runs great.

[@dTheHammerb]

Context man. Is this the 2.3L Mazda Engine?

[@benm12310]

Jeep 4.0 L

[@alphacorso4644]

Did u just use standard bearing or oversized

[@azdakrowflyz5963]

Standard

[@ppinoski]

He didn't check bearing clearances ?

[@christinad3425]

Is the whole engine out of the car? how are you rotating?

[@azdakrowflyz5963]

No the motor is in the vehicle, it's a jeep, I'm underneath it with all the journal bolts broke loose but not removed. The Pistons and rods had also been removed from the top.

[@fregas8]

Thanks

[@cebusam7545]

What about thrust bearings?

[@mikemarsh4221]

What kind of car?

[@papapsych2746]

Hey if your still active I got a question. My family has a Mitsubishi 4G69 motor in a Gallant, I changed the oil and used that long life garbage and half of it leaked out the front main without tripping the low oil light. The engine now sounds like a diesel, Is that indicative of some wear on the main bearings? I'm thinking about pulling the motor and replacing them along with the piston rings, motor has a 181k miles on it. Kind of want to do the bare minimum though, body and transmission are good, just the motor is a wait and see thing that I don't know if it will go bad.

[@azdakrowflyz5963]

So sorry to hear about this, motor issues can be very frustrating, I have a feeling that if you changed the bearings, hone the cylinders put new rings on the Pistons, then send the heads out to grind the valves and just rebuild the head, I'm pretty certain that's going to take care of all of your problems. If you can do the work yourself you will save a lot money.

[@papapsych2746]

@@azdakrowflyz5963 Would I be fine using the old valve stems, and should I replace most of the valve components, or should it be fine with just a lapping reassembly and lash adjustment? I don't have an alldata on this car anymore, and not sure it would even have the information I need since my last subscription was lacking. It doesn't justify their new pricing system for DIY single car subscriptions IMO. Again don't think they will have engine rebuild procedures beyond torque specs for head bolts, valve covers, water pumps, ect.

[@freedomvan2970]

Did you pull the spark plugs to get the crank to spin so freely? No compression?

[@GoldenLaserLLC]

Man, the pistons are removed

[@Dieselpwr]

Cool

[@drewmcneill4471]

This looks like a terrible idea, and I love it
