    Pump bearing install tips.

    The absolute best way I have found to install new pump bearings does not involve a press.

    Installing the clean driveshaft in the freezer for 10hrs is the start. This will allow the installation of the new bearings and spacer with very little effort.

    Next, put the clean stator in the oven @ 350 for 30 minutes. This will let the shaft with bearings to slide into the housing with no effort.

    Setbacks on bearings etc. remain the same.

    Seals must be installed last with this method but still easy.

    I have found this method to have the least effect on bearings and has worked great for me.

    Thumbs up

    Definitely great idea Duke....in similarity, I've done this in the past with putting bearings on pinions before I set the crush sleeve on street cars and it works perfect.

    Thanks for sharing !!! Sometimes a little simple physics goes a long way

    K.I.S.S.

    The only thing I did differently, is I heated the bearings for 2 minutes with a heat gun to get them warm. It slid together like butta!

    Didn't think of that!

    Is that the new heavy duty bearing on the front?

    Question

    Where did you get the inside spacer, and how do you install the seals? Also, what is the best way yo measure the backlash?

    Thanks

    Group-K for the spacer.

    The seals I installed after it cooled down with my floor jack handle and some grease. Took very little pressure to get then seated. I'm sure any kind of pipe would work.

    Dial indicator. Somewhere Fercho has a PDF on that.
