volvo d42 engine balancer gears

Hi does anyone know the correct way to time the balancer gears to the crankshaft. I have been told to align all the other timing marks which puts no1 cyl at tdc , then to fit balancer gear assembly with the 2 small bolt threads on gear wheels aligned together in the middle. Any help please!.

Hi Albert welcome to CMN :wave:

I am hazarding a guess here but are there any timing marks on the gears that drive the balancer shafts? They could be simple notches but I would imagine there must be some accurate way to time them.

Thanks Jeremy I have aligned all the marks at the timing gears and will continue with the rest of the engine build unless someone tells me a different way to time in the balancer gears.

Albert I would guess that the gears that drive the balancer shafts have a key to lock them onto the shafts so if the gear timing marks align I would think that this should be the correct setup for this engine.

Yeah I think it will be ok to go with that. My problem arose as I was unable to align the timing marks when dismantling as the bottom end had seized up, including the balancer gear bushes. The engine had water in the oil and had sheared the half moon key which drove the oil pump and created the problem.
