Naiad Feedback Sensor

[billwilletts]

I have read a few posts on the feedback sensor leak problems here. I find myself needing to replace mine. I have elected to replace the feedback assembly rather than rebuild it because it is pitted and neglected for many years by the PO. I have a Naiad manual and schematic but I don't see any diagram or instructions on how to remove and replace it. I believe some of you have done it before and hoping to get some advice on how to remove it and reinstall. Can anyone provide a step by step coaching to save me a half day of labor mistakes! Again I am replacing the feedback assembly which is part of the servo assembly. Here is a photo - you can see it has been neglected. Probably the only thing that hasn't been replaced on this side. Thanks.

Call Naiad and order the part and ask for instructions. Its been years since I replaced mine but I do remember a set screw from the top holding it in place. With that out, you push the entire assembly out the back. When you slide the new one in, you have to be careful not to push it too far or you will tear the o-ring. Lining up that set screw with the indent in the assembly was the most difficult part.

So the set screw is the only thing holding the assembly in place? Don't have to remove the servo or the hoses?

Sky is right in that the set screw is important. It is not that hard with good light . The servo behind the feedback unit needs to be removed , as the feedback has to removed from the rear . You will have to remove hydraulic hoses. Get some caps and plugs for the open fittings. They are 37 degree JIC fittings. This will help in not loosing a lot of fluid and more importantly, not getting grit and debris in the lines . It takes almost nothing to contaminate the system, especially the feedback unit .
