Convertible Top: Testing and Inspection

HYDRAULIC SYSTEMS

The power convertible top hydraulic system consists of:
- Two hydraulic cylinders
- Hydraulic lines
- Electric hydraulic pump and reservoir
- Dual relays

HYDRAULIC SYSTEM TESTS

NOTE: The convertible top will raise slowly or make abnormal noise if the hydraulic fluid level is low.

1. Remove rear seat cushion and back.
2. With the top down, remove motor assembly from the floor panel.
3. Remove the reservoir fill plug
4. Visually inspect fluid level. The fluid level should be at least at the bottom edge of fill hole, when motor bracket is held on a level (flat) surface. If low, inspect for leak in hydraulic system.
5. Motor/Pump:
a. Put reservoir fill plug back in place. Apply power to the motor and listen for operation. If the motor fails to run, check the voltage to the connector (10.5 to 16 volts required). Voltage below 12.6 volts will cause top to operate slowly.
b. Check the motor/pump for evidence of fluid leak. If leakage is seen and fittings/hoses and cylinders don't have any leaks, then replace the motor/pump.

6. Cylinders:
a. Check cylinder tubes for dents.
b. Check cylinders for leaks. Leaks are indicated by hydraulic fluid running down the cylinders. Small oil residue accumulation at seal is normal.

7. Repair or replace components, as necessary.
8. Bleed the motor/pump.
9. Secure motor/pump assembly into floor panel mounts.
10. Raise top.
11. Lower top and verify fluid level per step three. If low, add Dexron III Automatic Transmission Fluid as necessary. Do not overfill reservoir.
12. Install rear seat back and cushion making sure these components do not cause hydraulic line pinches and/or kinks.
13. Verify system operation.
