83 VR Help with selecting connecting rod bearings

[Droneh8tr]

Hey all,

So I got to the point of putting my engine halves back together, I look at #2 cylinders connecting rod bearings to the crankshaft and notice one of them is worn into the copper colored metal.

I would like to replace it, but I can't seem to figure out how to determine what I need.

 

On the end of the crankshaft are these numbers:

 

3 3 3 3 3 4

 

I don't see any markings on the sides of the connecting rods near the caps.

 

On the bearing that presses into the connecting rod I see this:

D3B

On the bearing that presses into the cap to the connecting rod, I see this:

D3B

 

Can anyone help me figure out what i should order? What COLOR should I get?

The markings on the rods are not 'stamped' into metal, They are in black ink.

 

Rod numbers should be 4 through 7, corresponding crank journal numbers will be 0 through 3.

 

Picture of a 1200 rod showing marking. This one is a number 7.

OK... well for now I'll say that maybe I didn't look close enough.. When I get home tonight I'll try to look closer..

Thanks

No go!

i inspected the connecting rod and it's cap closely and their are no marks. Any other ideas?

Thanks Prairiehammer, but the problem is I can't see a number on the connecting rod. I have the numbers on the end of the crankshaft as I mentioned above.

Maybe I should do the plastigage test and see if its still in limits.. Although I would think that if I can see the copper colored metal of the bearing, the safest thing would be to replace it.

 

Does anyone know the thickness of the bearings? If I knew that, I believe I could figure my issue out.

Don't the bearing shells have a mark of paint on them too.....to correspond with the chart.
