Recommended Posts

Thanks for the extra photos. Would love to add/ask a few questions but as I find myself doing round 2 with Shingles and it seems worst then round one I just have to be content with observing.?

After 6 month at the machinist we have some progress....:)

Cleaned up well,  bored 0.060" over.

Next is the bearings, all 13 of them, mains and rods, at $180 per bearing, there goes my budget rebuild....:(

So off to a bloke 3 hours away to pour all the bearings.

Cool thanks for the update I think I'm about to head down the same track as you and yes I'm probably going to blow my budget too hopefully the wife doesn't see by how much?. Who are you getting to do the bearing work? pm me if you don't want to advertise who it is. Thanks again Ben

Hi maok,

Good to see that the old girl will be coming back to life! Was up in Stanthorpe last month for the Apple and Grape Festival, had a great time, hope all goes well with the rebuild.

Here you go Ben, this is a big end of a conrod. They are smeared in clean oil at the moment, the oil makes them look rough. 

I couldn't get any pics of the mains yet but in January reminded me to do so. The block has surface rust on it from sitting around for awhile after it was acid dripped.

Mr. Maok, I hope those are not the rods that you are going to use, in your new engine. All those holes that are inside the Rod  bearing, that I see, and in the out side thrust flanges, is dirt in your bearing babbitt. Those particular holes, are are caused from a Dirty pour, that had skimmings from the top of the babbitt pot surface,  or some Guys just heat babbitt up in a ladle, and is poured into the jig, very crude. When you do it that way, the babbitt in the ladle will burn, and the burnt babbitt will go down the the bearing, and make the holes that you see. 

 

The problem is, the  holes are not just on the surface, they will go clear to the core surface on the rod. So now you have dirt, between the tinning, if there is any, and the babbitt, which means that it is not stuck, as nothing sticks to dirt.

 

Also, look at where the out sides of the thrust, touch the rod side, if that side is stuck, it will look like one metal, soaked in to the other. If there is a crack between the babbitt, and the rod, like water on wax, it will not be stuck.

 

I will post some pictures of what dirt looks like from the back of the bearing, and also what the side of a flange should, and should not look like.

 

It also looks like someone took Emery Cloth, to the inside of your bearings!

 

Thanks,

 

Herm.

@herm111  What you are seeing is a pic of one rod with oil smeared on the bearing, so it looks abit rough and dirty. I havent had much of a chance to inspect all of them as yet. I will clean them up and take a better pic for all to analyse and comment but this will have to wait after xmas. This my first poured babbits so I am very green on this stuff, the engine machinist said they were ok.

Yeah hopefully they are not as Herm observes as I many years ago went down the expensive track mind you when I pulled that engine they looked truly awful. Anyway gives me something to think about while I lay here in hospital. So pleased that there is this site👍🏿😁

What colour should this engine be painted? The engine from the car was a teal blue but had red underneath it.

I hope you left Santa a bit of Christmas cake and something to drink. That is a very nice delivery.

Yes, Santa delivered it to the right house where it would be lovely cared for, and by the looks of it your doing a great job in being her back to life, as a reward she will serve to well.

Thanks mate. Guess what? The blocks are slightly different. I'll post pics later.

They look as if there has been a stone hone in side the rod bearings , where are the machine marks from the cutting tool ? Like Herm111 I a little worried about the surface finish .
