Hi all,

Ordered the correct flywheel puller for this model engine, but having trouble removing the retaining bolt in the center on the crankshaft. Obviously, when I turn it, it turns the whole flywheel. I don't have an impact wrench and was wondering if anyone has any tips on removing this without one. I can always go purchase a compressor and impact gun (any excuse to buy new tools!), but hoping for a workaround here if there is one.

SN of the motor is 5337017 if that matters/helps.

Thanks!
