The balancer is in the way of the crank sensor. When he calls screaming about it, tell him the three bolts are M6 by 1.00 pitch and he'll need them to be about 75-85mm in length. (almost none of the typical puller kits have the right bolts.) In a pinch you can use 1/4" fine pitch bolts.

Torque on the two bolts for the sensor replacement is 13ft lbs.

Yes, definately my first time
