Harmonic balancer my husband needs torque specs on harmonic balancer for 1991 buick century

This is the bolt, but the answer is the size of the socket that fits it. If you don't have a full set of sockets and wrenches, doing job is impossible. If it is oversize, and I don't think it is, you can get larger specialized tool from Autozone for free and just a small returnable deposit.

Hello, the crank position sensor or (CPS) censor is located directly behind the harmonic balancer (or fly wheel at the very bottom). The sensor is located on the right side of the harmonic balancer when facing the front of the motor. You must remove the harmonic balancer to replace the sensor. You must also re-align the sensor with 30 thousands of an inch tolorence, or your car may idle rough or may not start. I own a 1990 Buick Century and just replaced my CPS sensor last month. There is a trick I learned to reinstalling the new sensor. Let me know if you need that information.
