Tuesday is my day off (when I'm able to take it), so I'm trying to get something done... First I had a doctor's appointment to review blood work (all good) and have my prostate checked... He really should consider a cute assistant for this kind of work. But anyway...
Today's project: Cam Chest.
The first thing I did was position this handy form-a-funnel to direct oil onto the J&S fluid tray, and in turn into a pan. It worked well, and kept things pretty clean. I really should've removed that annoying unused exhaust bracket first... Oh well, I'll get to it...
I collected a bunch of special tools for this project, but the little clips to hold the tensioners seemed unnecessary, and they were. I used a 3/4" open-end with a long extension through the box-end to work like a T bar, and this worked perfectly to unload the tensioner:
A roofing nail worked well to hold the tensioner in place:
The outer drive sprockets and chain came off pretty easily, although the $16 cam locking block was a little bit of a pain... It's made out of a hard plastic, and it didn't fit perfectly. I was able to gently malletize it into place, but it left some plastic shavings in the sprocket teeth. I'll just make sure I clean everything well. As recommended, I marked the outside of the chain to maintain orientation during assembly. The cam plate came out easily once the outer chain was off.
Note the little piece of tensioner that I found on the bottom of the chest... I'll inspect everything carefully. I don't think these would've gone 65,000 miles the way cggorman's did! I think these only have about 17,000 on them...
Very nice work and it seems you know what you're doing.
A friendly reminder, when a machinists works on cylinder walls it's good to bath, wipe clean and wipe oil over every machined part. To remove any metal fibers and prevent rust after cleaning.

I dunno about that... I'm trying to be careful and not f*ck anything up... I'm reading the factory manual thoroughly and watching videos... Here and there I get a momentary flash of panic thinking that I'm over my head, but then I just calm down and remember that it's just a bunch of nuts, bolts and gaskets. The only real trick is understanding the correct sequence of everything, and paying attention to torque values. Maybe an over simplification, but it gets me back on track!

Yes, good advice. Thank you. I really appreciate people's input!
Okay, my late lunch break is over, heading back to the garage.
But first, another quick bearing question...
Years ago, I was always taught that fresh bearings should be thoroughly cleaned in a parts washer, then blown out with air prior to use. Still true? Should I do that with the inner and out cam bearings prior to installation?
Same question with regard to lifters... I have new S&S lifters, which are packaged and sealed in light oil... When I'm ready for them, should I clean them thoroughly before installation, or should they be ready to go as is?
When I rebuilt my brothers S&S 88 engine, the lifters were already loaded with oil and the bearings are packed with grease. I installed as is. Engine runs strong.
Earlier today you post that excellent thread on your day at Thunderbolt Raceway with California Superbike School; Level 4. Very well done
And now all this goodness, right after you get a probing at your doctor's office; you are indeed the man!
Hahaha! It's amazing what you can get done when you're not at work! I would post a picture of my three lovely assistants who feed me grapes and beer while I wrench away... In between rubbing my neck and tending to the music (and fixing the occasional wardrobe malfunction), they reenact '80s music videos on the hood of the Ferrari while I try to stay focused...
