Thanks, JFP and Wayne. I'm in no great hurry right now as the IMS bearing isn't going to show up until early next week, so I'll pull the third tensioner today to see what happens. After all this work and over $600 just for the bearing, I want it to go in with a minimum of force on the flange to ensure I don't damage the seal on the way in.
The tensioners look to have minimal wear - only a small rub point at the end of each tensioner. My guess is that I don't have to replace them. Is there a good reason to go to the new design? If so this would be the time to do it. I've also read that you shouldn't replace all three with the new design because of incompatibility between one of the tensioners and its associated ramp. Is that true?
