So, I have a leak on the head of my motor from the bolt for the idler gear. I bought an o-ring (#23), washer (#22), and bolt (#9), as shown below.



See, http://www.hondaautomotiveparts.com/...FT+-+CAM+CHAIN

What do I need to do to replace these parts? Can I just remove the timing chain tensioner (after setting the cylinder 1 at TDC), and just loosen and remove the bolt? Or, will everything fall apart catastrophically, meaning that I have to take apart the cams and everything else first to get the job done?

Thanks

^ great link.
In short, do not remove the bolt.

1. Loosen the bolt enough to expose the o-ring.
2. Cut the o-ring off.
3. Clean the area with carb cleaner.
4. Replace the o-ring.
5. Tighten the bolt to the correct torque.

Just wipe clean, you don't want to spray something that dissolves oil getting in the engine.

^ not enough is going to get in there to have adverse affects.

op don't be scared of carb cleaner on this job.

Car Analogy

Right, I mean the bolt is still in place. How much carb cleaner is going to get past the threads into the motor?

If fluids can leak out, they can leak in. Plus carb cleaner isn't good for rubber seals.

Replaced the o-ring on mine a few weeks ago.......5 minutes tops.

Be sure to follow torque specs; you don't want that bolt backing out!!!!

And don't back the bolt out too far.

I thought the o-ring would be more visible, and kept backing backing to bolt out. Thankfully, I realized it was right in front of me before I had loosened it too far! I then cut the old ring (which had lost all elasticity), wiped the channel off, and popped the now one in place. Torque, and done!
