Tension Bolt
Make sure that both bolts are tightened equally so that flywheel sits straight in frame and
both fly wheel and crank pulley are properly aligned.
The correct belt tension tolerance is 120-140 lbs. If a belt tension gauge is not available,
the drive belt should have about 0.25" deflection when pressing down firmly on the drive
belt.
