Crankshaft Balance Sprocket Wobble
Need some help/ advice around what to do about a strange issue with the front of the crankshaft. I have a 1984 engine that I swapped into a 1986 body, and in doing so I switched out the 5 rib pulley system with a 6 ribbed system. I took off the balance shaft gear, swapped out the pulley, and took my car on it's first baby test drive. I noticed that there was a weird vibration around ~3k rpm and a wobble on the crank pulleys, and assumed it was a power steering pulley issue. I took it apart and found that the balance-shaft crank gear was wobbly/ not perfectly mated to the timing belt gear. I'm not entirely sure what could cause this, but I'm a little stuck on how to fix it. I replaced the power steering pulley with a simple washer, but the ~155 ft-lbs of torque that's applied doesn't effect the wobble, it's still there. any help would be much appreciated, I've attached a video of it starting to show what I mean (apologies for the horrible quality -_-).
