    Question Jet pump Rebuild by dealer

    I broke down and took my jet pump from my 2006 GTX Limited to the dealer to get it rebuilt. I did not have the tools or the knowledge so I removed the pump and prop and took the pump to them for the service. They did a very quick turn around and I am trying to assemble everything now.

    Here is my question/concern, when mounting the impeller and torquing the 12 mm Allen bolt, the pump get so tight the impeller will not spin. I only torqued it to 35 lbf-ft and not even close to the spec of 92 lbf-ft. Is there a trick to breaking in the pump or is there a problem with the rebuild?

    Not normal or expected. Safe to say that there is a problem and more questions than you asked may be needed to get to the answer you are looking for.

    Take it back to them... they messed it up... Take them the prop this time so that they can see the problem.

    Thanks for the feedback Jim and wkuadam07, I took the pump and impeller back this AM and they jumped right on. A lot of head scratching and reviewing part numbers and everything matched there. They took it apart and put another new set of bearings in and torqued the impeller. They had me out of there in under 40 minutes. The tech said he suspected that one of the races for the bearing was not assembled correctly but he has never seen that happened with this part before.

    Good find and good on the dealer! (even though it should not have been released like that)
