The new 166-4374 Ring Assembly is adaptable to the former water pump groups if a hole (X) is drilled through the water pump housing. Illustration 2 identifies the location and the dimensions for hole (X). This new hole (X) will accept the pin (A) from the new ring assembly (1). See Illustration 3. This will keep the opening in the new ring assembly positioned toward the bottom of the installed water pump. This will allow any fluid that leaks past the water pump seals to flow to the water pump weep port.
