Cat crankshaft bearing date codes

It’s in a ih9670
I will see if I can find anything
I don’t think there’s anything useful on these
I will try to find the block numbers later
It’s not at my main shop
Thanks for the help this far

 

I can’t find anything but a rust spot where I think the tag used to be on the side of the block. I am not the best on cat but isn’t stamped on the block somewhere

 

J01290
Seems to be the number stamped in the block between 5-6 though it would be under the tag like all there old construction stuff

 

It’s a 3zj
Mistook the z for a star like it had on the other end Grrrrrr. Guess the guy at the salvage yard hadn’t heard oil pans aren’t a lifting point

 

I gave my timing advance a little tlc and pin timed it on the fast side. starting and smoke and blubbering on acceleration are much better. The pump cam is pn 4p4698 and has 10.4 degrees etched on it
Pump is a 7e5888.
I was going to borrow a timing light from a tractor pulling friend and see what it’s at and how the advance behaves. What does anyone with more experience than me recommend for timing and advance adjustment. engine sn is 3zj01290 internals apear to be original and still has the aluminum head spacer.
