    Help with VX1100 Drive Coupler

    Hey guys. Im trying to remove the drive coupler from the drive gear housing on a VX1100 and I am having a heck of a time. I put heat to it and my 1/2" drive electric impact and it wont budge. Anyone have any suggestions?

    Anyone? Ive done at least 100 on the 2 stroke cranks (including sea doo's using a 6ft cheater). Are they usually this tough on the 4 stroke yammis?

    Refresh my memory... this is an MR1 engine right?
    Never done one myself, but referencing the service manual, I see that the entire reduction gear assembly is removed 1st. Then two proprietary tools are needed : a) coupler wrench & b) the rotor holder. How are you tackling it?
    Remember the gear is reversing the drive direction (as relative to the mr1 shaft rotation - engine is backwards). Regardless.... should be turning towards the flat coupler spots.
    Sorry - spit-balling here.

    Yes it is the MR1. Motor has been removed for an overhaul. I have both the gear and coupler tool and am turning towards the flat side of the coupler. I've applied medium to high heat and It just won't budge, I haven't pulled a cheater bar out yet. I never have this issue on the two strokes I work on besides sea doos! I guess I'll try a little more muscle and see how it goes!
