How to Pull Codes for a 1988 Mazda RX7
You can pull the codes from your 88 Mazda RX7 using a small computerized device known as an OBD I code reader. These tools can be purchased at any auto parts store. The Mazda RX7 comes equipped with an On-Board Diagnostics I computer (OBD I), which receives and stores trouble codes sent to it from sensors found throughout the vehicle. When a sensor detects a malfunction and sends a code to the computer, the computer illuminates a warning or service light on the instrument panel.
Instructions
- 1
Locate the diagnostic port found on the drivers side dash. Plug the code reader into this port.
2Put the key into the ignition and turn it to the "on" position, but dont start the vehicle. This will turn on most code readers. If not, find the on/off switch on the reader and turn it on.
3Wait for the code reader to interface with the Mazdas computer. Most readers will retrieve the codes automatically; for some readers you have to select the "Retrieve Codes" command on the face of the reader.
4Write down the codes the reader displays and look up their meanings in the code readers manual.
5Unplug the code reader and turn off the vehicle. Have the Mazda serviced or repaired based on the information obtained from the codes.

How to Pull a Harmonic Balancer on a 350 Chevy
A 350 Chevy engine may be any engine built by Chevrolet with an approximate displacement of 350 cubic inches. These engines were in continuous production from 1967 to 2002, with the last member of this series being the Vortec 5700. The Vortec 5700 appears in full-size Chevrolet trucks from 1996 to 2002. A modern 350 Chevy engine uses a harmonic balancer, also known as a crankshaft damper, to reduce the vibrations that occur when the crankshaft rotates rapidly. The crankshaft damper is a weight on the end of the crankshaft under the crankshaft pulley.
Instructions
- 1
Disconnect the central mounting bolt and washer from the crankshaft balancer with a socket wrench. Remove the mounting bolts from the pulley, and detach the pulley from the crankshaft.
2Attach Tool J23523F to the crankshaft balancer. Pull the crankshaft balancer from the crankshaft.
3Record the length and position of any weight pins in the front groove of the crankshaft balancer. This ensures the crankshaft balancer is properly balanced when you replace it. Remove the weight pin from the crankshaft balancer.
4Place the weight pins in their original positions on the crankshaft balancer. Apply a thin layer of Adhesive 12346141 to the keyway on the crankshaft balancer to seal the crankshaft joint.
5Align the keyway of the crankshaft balancer with the woodruff key on the crankshaft. Press the crankshaft balancer onto the crankshaft with tool J23523F. Mount the crankshaft pulley to the crankshaft, and tighten the mounting bolts for the pulley to 43 foot-pounds with a torque wrench.
6Mount the central bolt and washer to the crankshaft balancer so that the crown of the washer faces away from the engine. Tighten the central bolt to 70 foot-pounds with a socket wrench.
