MORE ON BALANCER HUBS
I have several balancer hubs that I’ve honed for slip fit tools. If you have an engine where there is a timing cover index issue from either poor dowel pin alignment or a crank centerline issue, you can still locate it properly. Remove the dowel pins or drill out the holes in the cover for clearance. Then, loosely install the cover and slide the balancer hub on. Finally tighten the bolts. You can also check for proper seal interface by applying a little assembly grease all the way around the hub’s seal surface, then slide it on and back off. You’ll see if the seal witness marks are contacting all the way around. Having external balance hubs with zero press work great for balancing cranks too.
