    Other are qualified to speak to capacitor question.

    I have swapped prop shaft gear on several projects.
    Start by driving the pin out using punch and hammer
    Save the pin for reuse.
    I use a 12 ton hydraulic press to force the shaft out of the gear…
    be prepared for loud groans …gear and prop shaft can be very
    tight fit…lube shaft before pressing.

    Once gear and shaft are apart….
    lube the shaft and the gear lightly
    align hole in gear with hole in shaft
    start pressing shaft into gear
    Use punch in gear hole and a punch in shaft hole
    to make slight adjustments to align gear to shaft holes
    The hole in gear and hole in shaft need to line up
    or the pin will not go in.
    Pin is quite important to function so it is well worth
    effort to get holes aligned to allow pin to be driven in.
    It may help to grind end of pin slghtly to round the end.
    Pretty fast and simple IF you have a press and a few odds and
    ends plus the right size punches.
    I will see if I can dig up old photos or pose some new ones
    to illustrate what I may not have made clear.
