Please, the the Timing Belt Sprocket, not the pulley. I already pulled the pulley with my pulley puller.
I'm talking about the toothed sprocket that the TB goes around.

I bought a timing gear puller for $12 at Kragen and then went to Orchard and bought 2 M6 bolts. The timing gear puller is just a machined block of metal with slits to retain the heads of whatever bolt you use. Since the Lexus timing gear has M6 taps, it came out quite easily with that.

You should have the brass looking tab at the 5 o-clock position. You either took it off and didn't realize it or someone disassembled this before and forgot it. Recommend you get a new one. Inexpensive I'm sure.

Forgetting it would have been hard since I didn't have any left over parts, bolts, or nuts.
I did look before re-assembly and there was no hole for an M8 bolt.
The timing belt was done once and only once before by a shop that specializes in Nissan and Toyota. It was done at 120K for the first time, about 155K miles ago.
The thing that irks me as that the passenger cam and crank shaft both had tool scratches from the previous change. I know I didn't do it because I used seal extractor that is non marring and the tool marks were on the opposite side of the shafts were I used the extractor, so I know it was the previous change. It's amazing that after 155K, there were no oil leaks, but in both cases, it looks like the scratches missed the seal lip(front and back). I wasn't surprised as they'd done the timing belt on another car of mine and and it was it's first timing belt change too. When I did it myself years later, one of the cams also had a gouge mark on it. It was the same tech on both cars and it's pretty obvious to me that he used a small screw driver or something similarly inappropriate and was not very careful.
So far there are no oil leaks on the SC400, but there are too few miles to tell for sure. I'm leaving the top TB covers off for a few weeks to watch for oil on the TB.
Yes, I set it to TDC before taking appart. Also counted teeth on the belt rather than just relying on the marks.
