    pump extension

    I was looking at the Riva instructions for a pump extension. It mentions using an alignment tool. Won't everything go back in it's original place just the same as changing the wear ring.

    They had previous problems with misaligned motors and this product. They are covering their a**es if something happens. The motors are not always aligned correctly from BRP or is someone has swapped motors or replaced the engine mounts. It will also show if the pump shoe is installed squarely.

    I think that they are telling you to do this as a precaution before putting in the longer driveshaft as an out-of-alligned pump/engine will have a tendency to put more strain on the driveshaft... Ron

    Alignment is not that critical as the shaft has crowned splines and allows for a lot of play.
