Unhappy need help in removing bow tensioner cylinders

I have really enjoyed reading and observing so many of you and your love of our E46 convertibles. I purchased my 2001 325Ci convertible on line with the promise that everything was in good working order on the vehicle. When I received the vehicle...you guessed it, top would not fully retract. Local BMW dealership diagnosed the bow tensioner cylinder on the driver side was leaking hydraulic fluid. Their resolution was quoted at around $2,600.00-ouch. That is when I found this forum and all the great remarks regarding Top Hydraulics. I have placed my order with Klaus and I am in the processing of removing the cylinders with the DIY instructions which were great. It seems that my last step is to remove those last lines from the valve block. Is there a DIY for this step? I would appreciate any and all expertise and wisdom from all you...Thanks in advance!

Re: need help in removing bow tensioner cylinders

Read the DIY for the main lift cylinders and the DIY for line 23 in the sticky, they both contain tips to remove the lines from the valve block. You'll need to disassemble the rear interior if you haven't yet.

Removing the lines is easy, installing them is a pain.

need help in removing bow tensioner cylinders

You do not need to remove the lines that run to the pump. Simply remove the cylinders. One cylinder has a hose permanently attached which connects to the other cylinder. This is the only hose you need to remove from it's routing along the back of the roof (beneath rear glass).

There are 2 designs of the bow tension cylinders, you have the design where the lines are not detachable from the cylinders so you have to remove them from the valve block.

You can attach photos to posts on this forum or read this: http://forum.e46fanatics.com/showthread.php?t=232424
