The torque depends on the flywheel material and the angle and diameter of the taper, roebuck. 35 lb ft would be reasonably suitable for most aluminium flywheels with a taper of the usual angle, and a diameter of around half an inch at the small end, but it is always better to check what is specified in the workshop manual. They will vary somewhat, and you can do very expensive and inconvenient damage if you get it wrong, whether too low or too high.
