Timing belt marks

Hi All,
I did my timing belt/water pump/etc this weekend. I used a kit from AirCabinMan from ebay. Everything went really well, but when I went to start my engine it ran super, SUPER ugly then immediately died. So I opened it up and re-did the timing belt a couple of times. Then I noticed that I was missing a tooth for the crank shaft position sensor. After googling about I found this link:

https://www.toyota-4runner.org/3rd-...-immediate-stall-after-timing-belt-job-5.html

1blink had the same issue as I did, a broken tooth (and surprisingly I broke the same tooth as he did)

Anywho, somewhere during the process of installing/removing the timing belt (multiple times) the mark on the belt for the crank shaft came off... I'm wondering if anyone has the kit handy that they could count how many teeth there are between the left/driver side cam tooth and the tooth with the crank mark. Or maybe just post a good, high res picture so I can count for myself?

Thanks, you guys rock!

You can time it just fine without any marks on the belt. Just use the hard marks on the pulleys and the engine. You'll be fine. Just like I said in that thread.

I had forgotten that little brouhaha.

69 teeth
 
I was doing a TB/WP on our 'super cheap dead Highlander' - not a 4Runner, but a very similar Toyota V6. And I stuck on the new TB, and lined up all the marks, that was fine... but... just wasn't quite right based on the hard timing marks. But the timing belt stripes were lined up!

After a short bit of confusion it dawned on me that I had put the TB on 'backward' - took it all off, turned it around, lined it up using the belt stripes, and yay, the hard marks agreed.

The belt stripes are a really nice feature, though. If you're using the hard marks you have to be extra careful to get all the slack on the tensioner side of the belt - none of it on the 'drive side' - it's very easy for a small bit of slack to be a tooth's worth. But with the marks - you don't really need to worry too much about where the slack is - just line 'em up, pull the pino n the tensioner, recheck everything.

Thanks man! This is exactly what I wanted! So to be clear, the marks point at valleys and there are 69 teeth/peaks in between?

Ya I had actually forgot to even look at the crank mark the first time, it was late already at that point. I was just using the hard mark on the crank pulley...

Yes sir, I had one in the garage in the package. I opened it just to count for you
 
I just finished getting the timing belt re-installed. For completeness there are 50 teeth between the left and right can marks.

Thanks again!
