Question about 1995 Subaru Legacy
You will need to replace the pulley to insure the pulley will run true. Depending on how bad the crank itself is damaged will determine if you will have to do a total rebuild and replace your crank. And yes, the gear does come off. There is a tensioner that keeps your timing belt tight. If you only need to replace the pulley and key way, the part # is W0133-1618586. This will be in your best interest if you can get away with only replacing the pulley. I have attached a pic of the camshaft and belt and gear that may prove helpful, maybe not. there is also commentary from another thread on this particular repair. I hope you find this very helpful!
A. The front of every crankshaft has a slot cut into it called a key way. There are corresponding cuts in the crankshaft timing gear and harmonic balancer. A key is used to align the key ways of all three parts to place, and keep, all three components locked together.
It is a cheap and effective way to insure that the balancer and timing gear keep their proper positions in relation to the crankshaft. In the event this key way is damaged, the crankshaft must be replaced.
If you decide to replace the crankshaft, keep in mind that you will end up doing a complete engine rebuild. Other options are buying a used engine or buying a remanufactured engine.

Yes it is removalble ,and the tension on the tensioner with out the specail tool,is hard to say,push the tensioner into the belt pretty firm,but not to much,or it will wine,the replacement gears are available threw the auto parts,but not the hydraulic part of it,crankshaft wear will be critical,to see that the new harmonic balance fits snug,and correct,keyway replacement should not be a problem,I just hope you don`t need a new crankshaft,I hope this was helpful,if so,please let us know,thank you.
