    How do you remove midshaft housing?

    Hello everyone,

    My 2012 VXR midshaft bearing housing is shot, water came through it. I was able to remove the coupling and midshaft. However i broke 3 bolts that hold the midshaft housing to the white bracket. However the midshaft housing doesn't have any threads at where the bolt go through so that shouldn't be a problem removing it. Well, the reality is that it is still stuck to the white bracket.





    Does anyone have any idea how to remove it?

    Thank you.

    It should just come straight off
    Maybe remove the pump just to make sure there is no parts jamming on it

    The heads of the bolts broke off because there is salt built up all around the threads of the bolts in the holes inside the aluminum housing. The same friction that stopped the bolts unscrewing is holding the housing to the bulkhead.

    Also the rubber part that surrounds the driveshaft bearings and seals is supposed to be part of the aluminum housing so you will need a new housing, seals, bearings, etc.

    I have ordered the new housing. I hope that's just the salt that hold the housing because i was banging on it with a hammer pretty hard.

    Try driving the screws into the holes with a hammer and punch.

    Penetrating oil and judicious use of a torch may help, too.

    ready for some bad drawings..

    the pins keep it from rotating , so hammering it will not help ..
    I would use some wedge shaped wood or tools to pry it away from the mid wall.

    Well, I blow torched where the bolts are and then pried it. That thing didn't even move. My next plan is to cut the housing into smaller pieces and then pull them out.

    How about a little water to dissolve the salt? I'm not sure how you'd soak those bolts. But I've had some luck freeing up salt-bound parts by soaking them in water. After all, water does dissolve salt. Maybe a pressure washer would do the trick.

    Another tip, but it's too late for you... when I see that a bolt is salted up like that, I'll tap it a few times with a hammer before trying to loosen it. That usually breaks up the salt and allows the bolt to turn. The one place where that's worked for me a number of times is on Kawasaki handlebars. The bolts that hold the bars to the stem are always loaded with salt and snap easily. A good whack on the head with a hammer breaks the salt.

    A big concern for you is to avoid breaking those bolts any further. You'll need something you can grab with a vice-grip to get those bolts out of the mid-wall. If you can't get them out, you'll have a real headache.

    I was under the impression that there were nuts on the back side of the firewall. However, don't see any in the parts diagram. I guess there must be inserts that are imbedded in the fiberglass or something. In that case, you're not going to be able to drive the bolts out the back.

    You might try building the bolt up with MIG welding, then weld a nut to it. MIG welding shouldn't stick to the aluminum casting, and the heat should loosen the threads. Work slowly so you don't cook the fiberglass!

    Worst case scenario, drill them out and install thru-bolts. Looks like you can get to the back side pretty easily to install washers & nuts. Of course, replacement bolts should have anti-seize applied to the shanks.

    I think kero dissolves salt
    So maybe spray them with kero
    Or even try salt away
    Otherwise maybe cut at each bolt
    Leaving a bit of bolt so you have something to grip when trying to bolt out after
