Crank pulley findings

IMG_5035

Couple of weeks ago, I was looking my spare engine, wondering what to do with it.

I don’t know why I started to look the tensioning pulley and how weird it looked when compared to the another one. Then, suddenly, I couldn’t find the timing stick anywhere.

I looked and looked but it was missing. I had to go and check the still intact engine in the AW11 to look for the timing stick (or pin? needle? whatever).

Well, it indeed was missing. It was sawed off. Looked like it was too close to the crank pulley. WHAT?

Shouldn’t the crank pulley be small enough to rotate without anything sawed off? I started to look for a tape measure, because something seemed to be out of place. I measured the smaller diameter first, and it was 130mm, which was normal. Then, the bigger one, which was 165mm.

Funny, it should be 145mm. Except… this is the HKS crank pulley! Looks like the stock one, but it is 20mm larger.

Wow! I was really surprised! It’s not the largest pulley available (well, the HKS pulley is already discontinued), but there is still at least pulley kits from NST and TechnoToyTuning, if there is need for a bigger pulley. Still, I’m going to stick with this.
