Abstract:
A method for remanufacturing a fluid end block of pump. The fluid end block includes a first bore defining a first longitudinal axis, a second bore defining a second longitudinal axis and a third bore defining a third longitudinal axis. The method includes enlarging, by a machining process, the first bore to a first predetermined dimension, the second bore to a second predetermined dimension and the third bore to a third predetermined dimension, inserting a first insert into the enlarged first bore and coupling the first insert to the fluid end block, the first insert having a first slot and a second slot, inserting a second insert into the enlarged second bore such that the second insert is at least partially received within the first slot and inserting a third insert into the enlarged third bore such that the third insert is at least partially received within the second slot.
