(Piston + Pin + Locs + Ring Pack + Rod Small-End ) + 2x(Rod Big-End + Rod Bearing) + oil

Is this formula right ?!


Rod bearing 50
Rod big end 481
Rod small end 127
Piston 525
Wristpin 118
Rings 48
Locs 4
Oil 4

So I have a total Bobweight of 1888g right!?



When balancing a crank I have half of this weight in each side of each journal ? So I have 2 parts of 944g in each journal?

1-2g of tolerance is fine in final balancing?

Correct

100% of the rotating weight (2 per journal)
50% of reciprocating weight
+ oil
