[Healeys] Crankshaft

Is there a need for one? Never needed one on my 100.

Begs the question: Anyone make an aftermarket balancer for the 100s? 
Without looking, I think there’s enough room for one.

    The "weakness" in the original 100, A-90 crankshaft was the lack of a
    harmonic balancer, coupled with a huge heavy flywheel.  More than
    likely, the crank that was sought after for replacement, had cracks
    near the rear main area where it vibrated itself to death. A case for
    not revving the engine over 4000 rpms. (Donald Healey set strict orders
    for all his racers to keep the revs down).
     
    They (BMC) fixed all that, or should I say Morris Motors, fixed it by
    adding the harmonic balancer to the early 100-6 engine.  Too bad they
    lost points in other areas, but by the time the 2912cc engine was
    developed, they did in fact fix all that...best six made!  Hank

    Don't over think this. Just because it will rev much better doesn't
    mean it gets used all the time, but it's there. Of course the addition
    of other lighter bits and an AL head and expensive harmonic balancer
    will have you at a greater expense. Speed costs money, how fast do you
    want to go?. The AH four makes excellent bottom end torque. The huge
    main caps handle it just fine. The original crank is the weak link. DP

    Wouldn't you have to beef up the main caps and add straps across them
    to handle the crank in higher RPM?  Just a thought with only 3 main
    bearings and no harmonic balancer.

      stronger basis for the other mods that will.

      Does it de-stroke the engine (shorter throws)?

            David, how does changing the crankshaft give you 2000
            additional RPM?
            Lighter rods and pistons, balancing, cam timing, bigger valves,
            porting, bigger carbs,  shorter stroke, even increased
            compression may all contribute to higher RPM but a crank alone
            will not make any difference, neither will a lightened
            flywheel.

                    they're steel and stronger, and should withstand more

                    the crank alone do it?
