I picked up an arcade game with a Kortek KT-2901M CRT. I removed the chassis to replace caps but saw that the Yoke assembly adhesive is cracked. What is the best way to re-adhere it so it does not move? It would need to be something high temp I imagine.

Good point. So far I've read this might not be an issue. Figure I'd gather more info before attempting anything. I do have to change caps though and will try before messing with this.
 
well, if it's floppy and loose I would be concerned. if it doesn't move then I would leave it be. I've never seen it crack into 2 pieces like that, I've seen D9200 yokes fall apart at the plastic part that rests against the back of the tube.
 
This turned out to not be an issue as everyone stated. Thank you.
The Monitor itself was not powering on at all and I got working again.
I scoured the forums and found other threads with tons of info.

I found a few schematics. This one was useful and this one had a troubleshooting chart.
The chart had me replace IC601 and I reflowed the power supply side components. That all got me power.
Then I saw it had partial horizontal collapse.
I replaced and marked the caps around IC201, I think, for the vertical and that fixed that issue. Best to do them all but I just wanted to get it to good.
Some adjustment and it was back to working condition.
👍👍
