Hello, What will the differences be in a 1949 D4 7U69XX and a 1953 7U207XX?
Other than the levers,and fuel tank,they appear the same. What about engines? tracks? transmission? Any advances?
Thank you for any information.
I think the major difference in 'em is gonna be that the older D4 has a one piece transmission lid and the newer one probably is going to have a two piece lid. Other than that, it's going to be whatever Cat updated as they were built. Best place to find out is going to be the Cat Parts book. .
