Hello, we have a CAT GC40K-STR with Lp gas powered GM 4.3L engine. this morning the engine began vibrating pretty bad. then heard a "clunk"..now engine is not vibrating. checked u -joints and harmonic balancer pulley but no obvious damage. engine starts and runs..but i'm wondering what could have caused this?

thanks
Jay

Fact of the week
In March 2002, identical twins in Finland died on the same day in similar accidents within hours of each other. A 70-year-old man was killed by a truck while cycling; hours later, his twin brother was killed by a truck on the same road, about a mile away, before the family had been informed of the first accident.
