JDcrawlers Messageboard

It has these three numbers casted on the block.
And I can not read much of the tag. Only can read the stamped
Numbers that are on the tag.

why does the original engine that came with my machine have three cast numbers. and the parts engine only have the one cast number?

I just bought a 350b and I would like to know what year it is. here is the serial number350BB 216141T the crawler loader has a hole in the block. something happened to the connecting rod. I have not taken it apart yet. here is the cast numbers in the block R55120 R55120 R55100 heres whats on the tag...
