    Intermediate Shaft Housing Alignment?

    Ive got a Yamaha SUV that I bought in a million pieces. I noticed in the intermediate housing bag there were two lil shims but no clue where they go... Does anyone know how to properly measure and shim the bulkhead????

    Being that the engineering of the IB unit is common among many models, I took a look at my VXR service manual . . .
    For installation, it simply mentions the following "Tip : If shims were removed, install the shims in their original positions."
    Yeah, not helpful, given your situation. It does not mention a shimming procedure, unfortunately.

    That said, perhaps look for clues on the mid-wall & housing to see if there is any signs of left-over shim footprints.

    Going from scratch, I'd install the jet pump and shaft 1st - torque everything down. Then install the IB housing.
    Rational; the drive shaft acts like a self-alignment tool. As you slide the IB up against the mid-wall, you'll want to probably get a feeler-gauge to measure the flush-ness of the housing against mid-wall. Note, you won't want to shim excessively, as the IB still needs to mate the rubber seal to the wall.
