96 Ford F150 4.9 inline 6 300 the crankshaft pulley is coming off
2 Answers
If just the part where the belts go is coming off then the damper itself is coming apart, these units have a hardened rubber section between the crankshaft hub and the actual damper and after time these deteriorate. And yes it is bad if it comes off while the engine is running. Your local parts store should be able to order you one or you can get them from summit racing, Dorman and other suppliers.
