Had to bite the bullet, there was just no way...
On the bright side I got a care package from Nils!

Bother. Bet you're getting good at that now. Hope you're happy with the touch ups to that cover!

Hey, where'd ya get those case bolts? Is that part of a Stainless Cycle set?
www.alloyboltz.com

Their case set was pretty complete, just didn't include oil pan bolts. They carry ARP stuff as well.

Cool, thanks!

Oh for sure, I think I had it split and back together in an hour! Didn't even need my notes for the shifter mechanism

Anyone have any ideas where I might find the rubber grommet that protects the generator wires?

Denver_Larry · « **Reply #55 on:** July 19, 2016, 02:54:24 PM »

Thinking about getting artistic with some black RTV unless someone knows where I can find one of these...

NobleHops · « **Reply #56 on:** July 19, 2016, 03:01:48 PM »

Larry,

Send a note to Bill Benton - he's got a big horde - he might have a gnarly stator he'll cut one off. Failing that, it's not really a very oily area - a few drops will accumulate in there weeping out the crank seal, but not much. You could make a little square rubber nugget 1/4 inch thick, drill it for the wire, slit it to install, and then seal it in there with the RTV. Make it sit a skosh proud so it compresses as the cover is installed.

Denver_Larry · « **Reply #57 on:** July 19, 2016, 04:27:27 PM »

Yeah that would work nice and would be easy enough to do. Just trying to prevent any more damage the wiring/sleeve down the road is all, not too worried about the seal there.

Slow n' steady...
Got my valve cover back today from Nils and it of course looks great! Did what I should have done while I was waiting for it and scrubbed up all the rockers and shafts, treated them to a light coating of oil and reassembled. Now just need to get my intake manifold up to Hondaman so he can finish up working on my head and I can get this motor sealed back up.

Is this it?

Denver_Larry · « **Reply #60 on:** July 28, 2016, 02:02:03 PM »

Certainly appears to be, thanks!

NobleHops · « **Reply #61 on:** July 28, 2016, 08:38:16 PM »

No, that's the one that the starter wire and the alternator wire pass through between the starter cover and the crankcase.

Denver_Larry · « **Reply #62 on:** July 28, 2016, 08:44:45 PM »

Well, I need that one too... Maybe I grab 2 and mod it for the generator cover.

Denver_Larry · « **Reply #63 on:** August 03, 2016, 07:10:50 PM »

Got the cylinders back from the machine shop yesterday and had some time to play with things tonight. Pistons are all in (without a ring compressor!) and it's a bit closer to being buttoned up. Just need my head and I'm ready to get it topped off.

I am a little concerned about the tolerance of the piston skirt to the cylinder wall, it is TIGHT. About 0.04mm. I don't really want to start rotating the crank around until I have the head on there to keep the cylinders in place since I'm not too keen on getting the pistons back in the bores again so I guess I'll wait before giving it a few rotations. Thoughts?

NobleHops · « **Reply #64 on:** August 03, 2016, 07:24:13 PM »

Forged pistons or cast?

Denver_Larry · « **Reply #65 on:** August 03, 2016, 07:49:42 PM »

Cast, Cruisin Image

I know Hondaman likes em tight, his machine shop of choice did them supposedly to his specs.

NobleHops · « **Reply #66 on:** August 03, 2016, 08:13:52 PM »

I think those are forged Larry. Edit, but I was wrong :-)

NobleHops · « **Reply #67 on:** August 03, 2016, 08:21:15 PM »

Do you have a total of .004, or .004 on one side with the piston in place?

Edit: good reference thread: http://forums.sohc4.net/index.php?topic=144157.0 , deleted bad info

Denver_Larry · « **Reply #68 on:** August 03, 2016, 08:40:45 PM »

.04 mm measured with calipers. Where have you seen that they are forged? Everything I have seen has them as cast and machined, and it makes sense with the price (they are cheap).

calj737 · « **Reply #69 on:** August 03, 2016, 09:03:12 PM »

CruzinImage pistons are cast.

NobleHops · « **Reply #70 on:** August 03, 2016, 09:06:01 PM »

My bad.

Denver_Larry · « **Reply #71 on:** August 03, 2016, 09:11:06 PM »

After reading that thread and converting my metric measurements, it sounds like I'm in the ball park. Less worried now...

Denver_Larry · « **Reply #72 on:** October 08, 2016, 03:25:05 PM »

Update finally!

After a busy summer, Hondaman and the machine shop finished up with my head and I was able to make some real progress with reassembly this weekend. I was short a locating pipe between the cylinder and head so I had to wait for a small care package to arrive...

All buttoned up for now, will play with the adjusting the cam followers another day. And one of these days I'll finish up the polish work on the clutch cover so that I can reassemble that for good.

On a side note, the CB got a new garage mate!

Very nice RC51 D.Larry! It reminds me of my dearly departed 2005. What a machine. Torque Beast.

Denver_Larry · « **Reply #74 on:** October 10, 2016, 03:03:21 PM »

Don't tell me you sent that thing to the great salvage yard in the sky?!
