Well I went ahead and bought the dorman brand harmonic balancer along with the crankshaft sensor for the timing cover I broke when I was removing the old harmonic balancer. So I was hoping that if I put a some clean motor oil on the harmonic balancer and the nose of the crankshaft it would slide on but to no avail on getting it to slide on so I had my parents take me up to the auto parts store to rent the installer and let me tell you what with the little to no room you have it was a really big pain in the back side to get any where with using that tool, so after an hour of fighting with it along with some mild cursing I gave up. So I was hoping that there was an easier to to install this like using a block of wood and a hammer or something along these lines. Also I was able to get a hold of a air compressor to install that bolt for the harmonic balancer. So any ideas to help me get the harmonic balancer installed would be very helpful.

Well I was told I had to use the tool or I would either mess up to nose of the crankshaft or mess up a thrust bearing in the crankshaft. Well since the tool I rented is not working due to a limited amount of room I have to work with will it hurt anything to use a block of wood and a hammer or is that not recommended.

I have replaced countless balancers. Make sure the shaft and the inside are clean and smooth, even a little burr will cause problems. Wiggle it a bit, slide it on and make sure it'* lined up with the key. Once lined up, put the bolt on and tighten it up.

Check the end of the shaft for any burrs, as well as the hole on the HB it'* self. As I said, even a tiny burr will cause a big headache. It'* a very close fit. I've had one or two that wanted to put up a fight. A fine file to bevel the end of the hole and wipe it down with clean oil, and all was good.

I don't have a file but I do have some light grit sandpaper and may also be able to get a hold of some emery cloth. Also I have compared to two side by side and they look identical to one another. I personally never had this much trouble getting one to go back on.

Start with the hole in the HB. I've seen a few where the edge is sharp, a tiny bump and it wont fit right. That'* why I give it a little bit to take that edge off. Make sure it'* clean after.
