[Eric.MacLeod]

hello i have a 1958 420 dozer and the rear sprockets have come up missing and i want to buy some more,i see some on marketplace but how can i identify correct ones for mine?

The casting numbers on the sprockets might be used to identify them. I don't know what the casting numbers were or if they used the casting number as a part number. This would be assuming your 420 was never upgraded with 350 chains and related components.

You can call Lavoy and see if he has a useable pair or suggestion off where to check.

You can give P B & H Equipment, in Antrim, NH a call and see if they can locate a useable set for you. They specialize in JD equipment.
