23. Locate the pair of cylinder hoses that need replacement. Refer to Folding Top Hydraulic Cylinder Hose Identification .

Important: Remove the two hoses connections one at a time. Repeat the following procedure for the second hose.

24. For each set of hoses being replaced, remove one hose by pulling straight up from the pump. Use a clean shop towel to control any hydraulic fluid leakage.
25. Push the hose back through the manifold plate.



26. Remove the hose retaining ring (1).



27. Remove the hose (1) from the manifold plate (2).



28. Push the manifold end of the new hose (1) through the manifold plate (2).



29. Using the installer BO-47666 , install a new hose-retaining ring onto the hoses.
30. Push the assembly cone (2) over the end of the hose (1) until the cone is fully seated.



31. Install the retaining ring (2) onto the assembly cone (1).



32. Using the installer BO-47666 (2), push the retaining ring (1) into place.



33. Remove the assembly cone (1).
34. Repeat the replacement procedure for the second hose.



35. Install a new O-ring (1) on each cylinder hose that you removed from the pump manifold.



36. Align the manifold plate bolt holes to the holes on the pump. This will ensure that the cylinder hoses are placed in the correct port.
37. Align the cylinder hoses into each port and push down until the hoses are seated properly in the hydraulic pump manifold.



38. Push down on the manifold plate (1) and verify that all of the cylinder hoses are seated properly.



39. Install the manifold plate bolts (1).

Tighten
Tighten the bolts to 10 N·m (89 lb in).

Important: 

•	If you are replacing hose sets for more than one cylinder, complete the procedure for one cylinder before you begin with another.

•	If replacing any of the pump side quick release hoses, hydraulic cylinder removal is not necessary.

40. Remove the hydraulic cylinder from the mounting location. Do NOT remove the hoses from the cylinder at this time. Refer to the following procedures:

•	Folding Top Header Latch Hydraulic Cylinder Replacement

•	Folding Top Side Rail Link Cylinder Replacement - Main Rail

•	Roof Retractable Panel Stowage Compartment Lid Cylinder Replacement - Upper

•	Roof Retractable Panel Stowage Compartment Lid Cylinder Replacement - Rear

•	Roof Retractable Panel Stowage Compartment Lid Cylinder Replacement - Rear Lower

Important: Improper hose routing can lead to hose failure as a result of rubbing or pinching.

41. Route the new hose set to the cylinder in the same way as the set being replaced.

Important: Remove only one fastener at a time so that the amount of slack between fasteners can be exactly duplicated between the hose sets.

42. Depending on the hose set, you may have to remove and replace the following components:

•	The tie wraps

•	The P-clips

•	The wire loom

•	The conduit





Important: Remove the two hoses connections one at a time. You will repeat this entire procedure for the second hose later. Refer to Folding Top Hydraulic Cylinder Hose Identification .

43. Use a small flat-bladed tool to release the retainer flex clip (1) from one of the cylinder hoses.



44. Remove the retainer flex clip (1).




Important: After you have removed the cylinder hose, do NOT move the cylinder rod. This will cause fluid to squirt out of the ports.

45. Remove the cylinder hose (1). Use a clean shop towel to control any hydraulic fluid leakage.




Important: Use caution when removing O-ring from the cylinder, steel tools can scratch the O-ring sealing surface inside the cylinder which could cause a leak.
