I was replacing the timing belt on my 2004 Sequoia today. I lined up the marks on the cams and the crank. Put on the belt, checked the marks 3 more times and started reassembly. After the harmonic dampener was back on, I turned the engine over 2x by hand as prescribed. Checked timing marks again and the cams line up but crank is off by one tooth! UG!!!

The new tensioner is installed and the pin was pulled. Can I just remove the tensioner, correct timing and reinstall tensioner with the pin deployed or do I need a new tensioner?

I’d say you probably need a new tensioner if the pin is already out

Well, I didn't follow your advice and hope it doesn't come back to bite me. I tried and failed to compress the tensioner with a C-clamp in an attempt to reinsert the pin. I just ended up reinstalling it in its extended state and tightened the bolts. The tensioner appears to have fully seated and looks properly aligned. The car is back together now and running nicely. I hope this doesn't put too much stress on the timing belt initially.

Well no predictions what it will do with it lol. But I wouldn’t of done it but I also couldn’t do that and get away with it at the dealership they watch everything we do.

Even if you released the tensioner pin, Toyota has a procedure for recompressing it using a vice. Good you figured it out. On these engines if I screw up timing, I do it a little differently. Rather than remove the tensioner, I remove the upper timing belt idler pulley, set timing, and while pushing downward install the pulley. This basically works on all V6/V8 DOHC Toyotas where the belt forms a "Y" with the idler (1MZ/3MZ verfied but probably also 5VZFE even though tension is set differently).

Next time you could use a bench vise to compress the tensioner and put the pin back in. No need to buy a new one.
