It's common for aftermarket balancers to fit to tight and not go on all the way... Once the balancer is on all the way the crank sprocket should be clamped between the step on the crank & the hub of the balancer, there should be virtually no torsional load on the key...

Quote: balancer is checked good and tight no sign of slop Tex It's not slop you need to be concerned with, it is whether the damper stops when it is hard against the crank gear or if it stops short because it sticks on the crank snout... With no timing cover on the engine install the damper & see if it clamps the gear tight or if when the damper stops you can still insert a .002 feeler gauge....

No slinger is pretty common, I prefer to use one but it isn't necessary, but like mentioned aftermarket balancers tend to be a tight fit.... Check it out, hate to fix the damage & not fix the cause... "The Armies of our ancestors were lucky, in that they were not trailed by a second army of pencil pushers."
