I recently purchased a D3B Z dozer. I have several questions that I have not yet been able to find answers to. The Product Identification number is 27Y04311. I believe it is early to mid 80's. Can anyone identify the year from the number? Also, what is the difference between the D3B and the D3B Z? does the Z have any meaning? The engine model is a 3204 Z. Engine Serial # is 45V56451 Any information is appreciated. Thanks!
The Z has no meaning that I know of. I suspect that it may be either something associated with the manufacturing location or as an aid to anti-forgery in a similar way to the asterisks before and after the machine, engine & transmission Serial Numbers on the plate. Your machine was manufactured in July 1986.
Thanks for the information. Much appreciated!
I have a D3B as well, 1 year older. I love the little thing! What are you using yours for?
