jp4z,
thanks for following up. Indeed, it was Lookup who posted the pictures, and you are the one who asked about the longevity of rebuilt pumps. Sorry about the mix-up, jp4Z and Lookup!
We rebuild lots of convertible top hydraulic pumps, on a daily basis, and I know that we are doing an excellent job (I hate to sound boastful, but I talk about technical issues the way I see them). Obviously, I cannot predict exactly how long our rebuilt pumps last, because there are a lot of factors coming into play. We put in far better seals and we undo some design flaws. Under normal circumstances, I would assume that our rebuilt pumps should be good for some 30-50 years. The pump we ship to you will perform better than a brand new one.
We offer core exchange, by the way, where we ship a pump from our inventory first. Same price as the rebuild service where you send in your pump first, but there is a refundable deposit added. For more details, see
Nissan 370Z Hydraulic Pump Rebuild/Upgrade
By the way, folks, please do not try to disassemble the pump yourself to see if you can "fix it" - this would likely end up in disaster, and we would probably have to charge you extra.
Access to the pump is not very difficult; removal and replacement is a DIY job if you have a little patience. The same is true for any repair to the 370Z hydraulic top system - let's all together create some easy-to-follow DIYs with good pictures on this forum, for many years of use in the 370Z community.
Take a look at the illustrations below. The pump is under the soft top storage compartment. With the top up and the storage compartment open, remove the plastic tabs that hold the storage compartment liner in place. With the liner removed, you will find the pump in a grey-ish foam cover. Unscrew the T27 Torx bolt that holds the u-shaped piece of sheet metal in place (the mounting bracket), bend up the mounting bracket, pull or carefully cut the tape that joins holds the foam casing halves together, and take out the pump. Now you only have to unplug the pump from the wiring harness and disconnect the hydraulic lines (hoses). Disconnecting the hydraulic lines requires only that you unbolt the manifold plate on top, which holds all the hydraulic lines, and then pull up a little on each hydraulic line individually. The hydraulic lines will stay within the manifold plate - they are retained by small snap rings, and they will not get mixed up.
I hope that answers your question...
Klaus
