I asked this on my project blog, but in hopes of reaching a wider audience (no offense to my 3 or 4 loyal readers, and of course you either Mom) I will ask this here too.

I started to put on the harmonic balancer pulley, but it doesn't seat all the way - see the picture. I tried pulling it down with the bolt and washer but it only goes so far, and doesn't get flush with the end to the shaft. So I have to get some bolts that fit the pulley, 7/16 fine thread which did not come with my puller set. When I disassembled it originally I just used a regular gear puller, but now I don't want to muck up the paint so I will do it right. Anyone have an idea what I'm doing wrong? There is just the timing gear, then the seal carrier, and then this pulley. I greased the inside of the cork seal prior to trying the pulley, so it shouldn't be hanging up on that?

When I put together my straight 6 Triumph engine, I had a hard time because the keyway (slot in the pulley) was binding up. After cleaning the key and keyway it went together much better.

Since the key isn't visible in your photo, Richter may be on target; good practice is that you don't assemble with the key fully in it's slot but protruding somewhat, to be tapped fully in when the damper is in place. My second guess would be that it's hung up by the front slinger/seal assembly.

I would assume that in order to keep it tight there would need to have some tension on the pulley. Check the alignment with the other pulleys .

That is what it is supposed to look like. As Josef mentioned, if the shaft was flush it would never clamp the pulley down tight.

...if the shaft was flush it would never clamp the pulley down tight.

Of course!!! Disregard my earlier unintelligent response.

Thanks for the reality check guys, that makes perfect sense. I measured the depth to the seal and the pulley and that is all the further it's going to go, so we're all good. Pulley reinstalled and on to the next thing.
