Can You Install Main Crank Bearings With Engine In Car?

10 posts in this topic

So-

You've hand polished the rod journals while it's still in the engine- and now you want new main bearings on the crankshaft, too...

 

Remove the crankshaft you say?  Nope, no need to. As long as the journals are in good shape- new bearings will prolong your engine's life.

 

How to?

I like the sub-titles. Below is one of my favorite parts of the video.

The  thing is I have seen mains being replaced in the vehicle. The worst part being getting the oil pan off with a crossmember below. This is a Chrysler video, of which there are several versions but this one will suffice:

Ronnie, I had no idea what you were talking about until I clicked on closed caption.  You're right.  And I needed a good laugh.

I did my 7 main 6 Cyl. Mustang from the ground, it worked perfectly.

Yes, it can be done. I've never seen it done with a pry bar like he did. I've used a flexible piece of nylon to run it around the crankshaft after tapping on it to get it moving. Loosening all the main cap bolts slightly before changing the shell makes it easier.

I liked the tools used on the delicate bearings too. I thought at first the lady foot was to remove the used bearing, but it looked like the new one which was reinstalled, but not before cautioning not to raise the bearing surface with a fingerprint. Apparently the dent from the back doesn't matter;) It looked like he forgot to straighten the dingle arm too?
