How to Remove Main Bearings Without Removing the Crankshaft - Cool Trick Using a Cotter Pin!

This is a trick many experienced mechanics already know. Expertly executed by my friend, a master technician. Thank you Steve for this great tutorial to share out.

(Installation is the reverse of removal)

Oldschool knowledge like this should be shared more frequently.

I have used this method many times and I am glad someone has shown others this technique.

Thanks for sharing this technique.
I was able to roll out successful my main bearing shells in my Elantra and replace full set shell and crankshaft Thrust washers.
No driving the car again.👍💯

I watched three videos showing this method, but couldn't figure out the trick. Had to see the other side of the rod for it to make sense. Thank you, sir.

I've done this at the track more than once. Great trick to have up your sleeve

[Topper-gfxl]

That is pretty slick. I used to use a thick feeler gauge to push them out.

[wulfclaw]

Thank you sir ! This is some wizardry for sure !

[camerong]

Does this method work with thrust main bearing

[carlodonnell]

I at first thought that it is the other side of the pin that rotates the bearing out, but it is really the head of the pin/screw etc that pushes the bearing out.ANOTHER THING IS.... SHOULDNT ALL THE MAIN CAPS BE LOOSENED TO MAKE IT EASIER FOR THE BEARINGS TO BE PUSHED OUT?

[tammygarcia]

So if my crankshaft bearings are bad, and I have this done will that fix the problem instead of replacing the engine?

[jessewoody]

NOICE. Nothin like some old school work.

[mycentsrc]

OK Now you took it out is there a video of you putting out the new one back in?

[rexmasters]

If I am changing the main bearings its after the block is serviced at the machine shop.

[michaelsept]

How do u get the new ones back in tho?

[lieberfreialsgleich]

I understand how you change the bearings in the middle, but how do you change the front and back bearings?

[ErikPryor-zn]

May not work on located thrust bearings or integrated thrust/main bearings

[andreasvenator]

now if we could see someone seating the new half as well we´ll really be amazed!

[myjeepwjarebuildpaulsteven]

I Think this method will work on my jeep to
I hope😵‍💫

[bluegill]

Does this process also work for the bearings on the very end

[robbernard]

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.
