Straight 8 Main bearing removal?

Unknown

I'm currently breaking down a straight 8 from a Commadore 8 1951 in southern Cali. I was hoping someone might point me in the direction of a good puller for the front and rear mains.

Thanks in advance.

You can make one in a few minutes. Take a piece of angle iron long enough to span the studs that you removed the bearing cap nuts from, and drill two holes that will line up with the holes that are tapped in the bearing caps for the oil pan bolts. Now just insert two bolts long enough to screw into those holes, and with the angle iron on top of the studs, as you tighten them , the cap will pull right out.

Or you can use a slightly cruder way ... put the two bolts back into the bearing cap and use a suitably sized crowbar, prying under the bolt heads, working back and forth, easing each one out a little at a time so as not to cock the cap in the block. I did it this way until I saw one of the Hudson factory pullers at a local chapter flea market years ago ... the seller had no idea what it was for!

Thanks for the ideals guys... I think I'm going to try and make what I need. If any know a good machine shop incase my welds come out less then desirable in the Los Angeles area (Van Nuys) I could use the reference.



Here's the drawing... I'm I missing something?

I have a bearing puller made like your drawing. Made from about 3/4 inch stuff. It was made for my Dad over 60 years ago by a TVA machinest. It has pulled many Hudson mains over the years.

And it's basically what the factory puller looks like, except the large U-shaped piece is bent from "flat bar" stock, about 1" wide and 1/2" thick. The short piece that the bolts go through is slotted in from each end rather than having holes drilled in it. That piece is roughly 3/4" wide and 3/8" thick.
