I took the sage advice of several members earlier this week and bought a new harmonic balancer for my 250. The good news is I can now time my engine because the mark is in the correct location.
The bad news is that when I drove the balancer on the crankshaft, it hit the timing cover at about the same time that it bottomed on the crank's timing gear (per the Haynes manual instructions). I'm a little scared of this arrangement with no bolt, but I used the puller to back it off enough to clear the cover.
After starting the engine, I noticed that the new balancer wobbles enough to still scrape the timing cover/oil pan lip. The wobble goes away at speed.
Should I pull the balancer a little farther away from the cover, or should I go demand my $95 back?
My brother is a diesel mechanic and his suggestion is to carefully locate the high side of the balancer and then whack it with a big hammer to shift the outer ring on the rubber. I think he's too used to working with very large parts. However it is easier than taking the radiator out again.
Any help would be appreciated.
