Set the J 8001: dial indicator set to zero.
Pull up on J 24773-A: pump remover.
Proper end play should be 0.13-0.92 mm (0.005-0.036 in).
The selective washer (616), which controls the end play, is located between the input housing (621) and the thrust bearing (615) on the oil pump hub.
If the end play measurement is incorrect, refer to the table End Play Specifications . Choose a new selective washer (616) based on the original selective washer and the information contained in the table.

If the dial indicator shows no end play, the selective washer (616) and thrust bearing (615) may have been misassembled.
Correct the end play by changing the selective washer (616).
