Hi guys

İ have broken the camshaft chain and i had 3 slightly broken teeth on the crank gear.
So i removed the gear with a hot press and remanufactured a new gear like the oem.
İ installed the new one by hot press but now there is 4-5 degrees difference btw the oem and the new installed. i can adjust the timing with the timing gear on the camshaft i think, but the main problem is do i need a synchronization btw the crank and balance shaft ? Does balance shaft is a part of the "balance of crankshaft" ?
Does anybody knows
