Chevrolet Camaro Berlinetta, RS, Z28 Repair Manual 1982-1992

PISTON RINGS | INSTALLATION
(Refer to illustrations 19.3a, 19.3b, 19.9a, 19.9b, and 19.12)

1. Before installing the new piston rings, the ring end gaps must be checked. It is assumed that the piston ring side clearance has been checked and verified correct (Section 16).



2. Lay out the piston/connecting rod assemblies and the new rings sets so the ring sets will be matched with the same piston and cylinder during the end gap measurement and engine assembly.



3. Insert the top (number one) ring into the first cylinder and square it up with the cylinder walls by pushing it in with the top of the piston (see illustration).
   
   The ring should be near the bottom of the cylinder at the lower limit of ring travel. To measure the end gap, slip a feeler gauge between the ends of the ring. Compare the measurement to the specifications.



4. If the gap is larger or smaller than specified, double-check to make sure that you have the correct rings before proceeding.



5. If the gap is too small, it must be enlarged or the ring ends may come in contact with each other during engine operation, which can cause serious damage to the engine.
   
   The end gap can be increased y filing the ring ends very carefully with a fine file. Mount the file in a vise equipped with soft jaws, slip the ring over the file with the ends contacting the file face and slowly move the ring to remove material from the ends. When performing this operation, file only from the outside in.



6. Excess end gap is not critical unless it is greater than 0.030 to 0.035-inch. Again, double-check to make sure you have the correct rings for your engine.



7. Repeat the procedure for each ring that will be installed in the first cylinder and for each ring in the remaining cylinders. Remember to keep the rings, pistons and cylinders matched up.



8. Once the ring end gaps have been checked/corrected, the rings can be installed on the pistons.



9. The oil control ring (lowest one on the piston) is installed first. It is composed of three separate components. Slip the spacer expander into the groove (see illustration), then install the upper side rail.
   
   Do not use a piston ring installation tool on the oil ring side rails, as they may be damaged. Instead, place one end of the side rail into the groove between the spacer expander and the ring land, hold it firmly in place and slide a finger around the piston while pushing the rail into the groove.
   
   Next, install the lower side rail in the same manner.

RADIO | REMOVAL AND INSTALLATION

1. Disconnect the cable from the negative battery terminal.
   
   CAUTION: On models equipped with a Delco Loc II audio system, disable the anti-theft feature before disconnecting the battery.



2. Remove the screws retaining the console bezel and remove the bezel.



3. Remove the screws retaining the radio to the console and pull the radio out.



4. Remove all electrical connectors from the rear of the radio. To simplify reinstallation, label the connectors with pieces of numbered tape.



5. Installation is the reverse of removal. The locating lug at the rear of the radio will position it correctly when the lug contacts the receptacle in the console frame.
   
   Always connect the speaker wiring harness before turning the radio on to prevent possible radio damage.
