Balancer Question

[stockcar5]

ati told me they recommend rebuilds every time the motor is rebuilt. i think this is overkill. i do mine every other year (80 nights). ati will also recommend what durometer of orings to use based on your application. they also sell a rebuild tool kit to make it easier.

We just had our current SB2.2 gone through and when Hendrens pulled the ATI off the crank, it was galled...Could not pull the hub off the outer, so we got a new aluminum hubbed ATI...saved a little reciprocating weight! LOL

We have a limited engine that we use a solid aluminum ballancer on. (we made it on the lathe) This engine has a crower ultra lite weight 4340 crank in it. It has been run for many years like this with no bearing issues. We have also run this in selected late model shows with a forward to mid pack finish. Why have we not had problems? It is a small cube (358) 18 degree engine. What are we doing wrong?
