Convertible Top Motor: Adjustments

ADJUSTMENT - HYDRAULIC MOTOR/PUMP BLEEDING PROCEDURES

After replacing any component of the power lift mechanism or if convertible top does not start to raise within 2 seconds after the switch is activated, bleed the convertible top motor/pump assembly

1. Lower the top to the full down position.
2. Remove the rear seat cushion, seat back and inner quarter trim panels.
3. Completely detach cylinders from attaching points (mounting bracket nuts and pivot bolts attaching cylinder shafts to top linkage).
4. Remove motor from floor pan.
5. Hold cylinders upside down (cylinder rod pointing down).
6. Hold motor/pump assembly with reservoir up. The rubber fill plug will be at the top.
7. Raise motor/pump fitting to at least 2 inches above the horizontal rear seat back reinforcement.
8. Cycle system at lease once, making sure cylinders can extend without obstruction. Allow for two to three seconds stall. There may be a percolating or gurgling sound, which indicates that the procedure is working.
9. Hold cylinders in normal position and cycle system at lease once, making sure cylinders can extend without obstruction. Allow for two to three seconds stall. There may be a percolating or gurgling sound, which indicates that the procedure is working. At this point, any air in the system has migrated to the reservoir.
10. Rotate and raise the motor/pump assembly so the reservoir is in the up position. The rubber filler plug will be at the top.
11. Remove the rubber fill plug from reservoir. Fluid level may be low.

CAUTION: THE MOTOR/PUMP ASSEMBLY MUST REMAIN IN THE CURRENT POSITION UNTIL THE RUBBER FILLER PLUG IS REINSTALLED.

12. Fill the hydraulic system by adding Dexron III Automatic Transmission Fluid to the reservoir. The fluid level should be 13 - 20 mm (1/2 - 3/2 inch) below the top of the reservoir.

CAUTION: DO NOT OPERATE THE FOLDING TOP SWITCH WHILE FILL PLUG IS NOT INSTALLED ON MOTOR ASSEMBLY.

13. Install rubber fill plug.
14. Secure motor/pump assembly into floor mounts.
15. Place the cylinders into original position with hose pointing fitting rearward.
16. Install pivot bolt attaching cylinder shaft to top linkage. Ensure all rod eye components are present (foam, plastic bushing and plastic lock washer).
17. Install cylinder mounting bracket and nuts. Ensure all trunnion split bushings are present. Tap folding top switch to adjust cylinder length, if needed.

WARNING: HYDRAULIC CYLINDERS PRODUCE ENOUGH FORCE TO PRODUCE SEVERE INJURY IN CASE OF PUNCHING. KEEP HANDS AND FINGERS AWAY FROM MOVING HYDRAULIC CYLINDERS.

18. Install all hydraulic lines clips and secure hydraulic lines to body.
19. Verify system operation.
20. Install the inner quarter panels.
21. Install rear seat back and cushion and ensure that the seat back/seat cushion do not pinch or kick the lines.
22. Verify system operation.
