i'm finishing up my heads and cam install and tonight while i was bolting up the water pump, i noticed that there wasn't much clearance between the pump and the balancer? is this normal? did i put the balancer back on wrong? i tapped it with a rubber mallet to get it started and then i put the bolt back in the crank and let it tighten the balancer the rest of the way on it. just curious if i have done something wrong or if this is just the engineering. thanks alot!
