My mistake was getting in a hurry and doing exactly what you described.. while using an air rachet!! I knew better than that but had a lapse of reason.
The MB balancer is marked at 0 TDC, 120 derees and 240, which are you TDC's for the other cylinders. Also the fact that there is an upgrade bolt to M8 x 73 suggested should have been a red flag. Again, experience is what happens when you screw up.
