We were going to drill and tap the crankshaft snout but was given the idea to use Locktite. I ended up using Permatex green sleeve retainer instead. Now when running the engine I notice a slight wobble and noise again. Seemed like the HB was seated well when I put it on, and let it cure for the 24 hrs as instructed. I believe I have to heat up the thing to 400 to get back off. Oh brother. I tightened the belt pretty tight. I also put some washers behind the fan to act as a spacer to get it closer to the radiator. Am I in for taking it all apart again?

If the balancer is wobbling, don't worry about heating anything- - - -the bond has already failed. Just pull it off, clean everything up, and drill and tap the shaft.

If you determined there was no wobble in your HB, Could be something else going on. Unfortunately I don't know what it could be. When rebuilding my 235, I ended up going the drill and tap route thanks to Jerry. Help him out Jerry. What could be causing his issue?

It's a steel core that is (should be) a press fit on the crank shaft.
Then a rubber isolator supports the steel outer part.
The rubber deteriorates over time, if yours is failing it may wobble and knock. | | | | | Joined: Feb 2004 Posts: 29,740 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,740 | Just because it's not loose doesn't mean it can't wobble. If it was not aligned properly because of wear to the balancer hub or the crank snout when it was installed, all the Loctite did was make the wobble permanent. The only fix would be to remove the balancer and all the Loctite residue, thread the crankshaft, and pull the balancer tight against the timing gear with a bolt. That eliminates, or at least minimizes the misalignment. The alternative is a different crankshaft and/or balancer.

If the fit is loose bolting it on might not be enough, it may hammer out the key and or loosen the bolt with time | | | | | Joined: Oct 2012 Posts: 307 'Bolter | | 'Bolter Joined: Oct 2012 Posts: 307 | Lincoln is probably correct. It was a little tight when I put it on, but that little bit of room when I glued it in is probably the culprit. I'll have to end up getting another HB I imagine.
