1997 Civic HX, 5MT, 305k miles stock, D16Y5 engine

Question: When installing a new crank pulley/harmonic balancer to my D16y5 engine, is there something I have to do with getting the engine to Top Dead Center or will the new pulley only go on "one way"?
Note I am NOT changing the timing belt.

Background: My stock engine harmonic balancer/crankshaft pulley came apart. That is, the outer part which has the AC and Alt belts, held on by pressed rubber, is no longer secure to the inner part of the pulley. When this happened, the alternator and A/C belts came off and with the alternator belt beginning to eat into the timing belt cover. I pulled the car over and had it towed. I got to look at the car yesterday finally, took off the alternator, AC and PS belts and was able to spin the outer part of the pulley and it was going back and forth on the inner part. So in diagnosing the problem I completely changed the alignment of the timing marks on my installed crankshaft pulley.

So when I put on the new one I ordered (OEM no longer available new), will I just be able to slide and install it right on in the correct position without having to figure out TDC ? Again I am not changing the timing belt, just wanting to put on this new crank pulley so I can use it for short distances before I go in and do the timing belt (I have to work on some other cars of mine first).

Any help is appreciated.

 

Yea they have a key so line up the slot and key and slide the pulley on and torque the bolt, I recommend buying a new crank bolt and key as well its very cheap.

Thanks ! This is what I wanted to know. I can take the old one off and put the old one on, lining up the woodruff correctly and such so no such worry about TDC is what I am reading.

Is it common for these pulleys to separate over time ?

 

It is common... especially in the Northern and coastal states. You do not have to worry about TDC... just install as stated above.
