Scott,
Close, but no cigar.
That pdf document has 27 torque specifications, and not one of them is for the balance shaft.
Do you know what engine that pdf is for? TheNuker had a LSJ, now an LDK. Comegetjoe has a LNF.

I'll try to remember to check the service manual this evening.

Page 15 shows it for LNF. I used this doc for my engine but installed the ZZP neutral balance shafts so I never noticed there was no spec in it for the balance shaft drive sprocket bolts.

37 ft-lbs according to Cloyes, who I think I read was OE for Ecotec timing sets
