I changed the Timing Belt on a 1991 240 this weekend. Everything went smoothly, until it was time to remove the Crankshaft Pulley. It wouldn't budge, so I purchased a pulley puller from the local discount auto store. I got the pulley off, replaced the Timing Belt, reinstall everything and it cranks fine. However, the crankshaft pulley seems to wobbles terribly, as if it will fly off any minute. I have rechecked / retightened the crankshaft pulley bolt, and it seems to be secure.
Now that I actually read the entire FAQ, I see why I should NOT have used a puller on this pulley, aka "Harmonic Balancer"! My shop manual !! The wobble is TERRRIBBBLLLE! How can I tell if the harmonic balancer is about the break? Should I go ahead and replace it now, or just wait until time for another big repair? Will it last until the next timing belt change?
