I weld for a living but for some reason that scares me.  Did it warp?  Are you using a 110 welder?  I am planning on riding my 360 to sturgis from WI this summer so I too want to put some miles on her.

millin - Yes. Hobart 110v welder. Doing short beads while moving quickly was my attempt to keep the heat down and minimize the warping.
But yes, it still warped although not terribly.
Once I got the top shell completely welded I spend a fair amount of time with a rubber mallet, an assortment of 2x4s, and a 6x6 flat iron of the back of a table vice and just pounded the correct shape in like an olde worlde blacksmith. An English wheel would have been nice. Ground some of the beads down with a wheel and brush, then pounded some more. Turned out well in the end.

Sonrier and NBraun - thanks.

My company has been having the required yearly recurrent training for all of us pilots this week. Make sure we all still remember the rules on flying planes. Basically days of sitting in a conference room trying not to slip into a coma with the rare interruption of an interesting discussion.

Anyhow, I finished getting the lower end back together.

Hopefully what this is all supposed to look like. Stuff in the gears is assembly-grease. I thought it would work into the cogs a bit better. Live and learn.


Put the new seals in. I just put a small amount of oil on my finger and ran it around the mating surface. Hopefully that will keep all the oil adequately inside.


I am a bit curious about these plates that rest under the crankshaft/rods. Only theory I could come up with on my own is that they help prevent too much oil from sloshing/splashing up into the moving crankshaft. Anyone with more experience have input on this?


The crankshaft mechanism, for those who haven't yet seen one.


Organizational attempt at not ending up with orphan pieces.




I put in heavier clutch springs and new friction plates. I didn't realize how thin my old ones had gotten until I compared the new and old. I knew I was going to change them out so I never measured their thickness but the old ones were pretty worn.

Anyhow, old spring-new spring. I'm sure you can tell which is which.





Decided to try out an anti-friction coating since all the new performance pistons for cars and such seem to come with them. Why not? I made a drill bit piston holder and taped my drill trigger in the slowest setting to spray these. Turned out pretty uniform (even though in the picture it looks like there are irregularities it feels and looks consistent in person). Anyhow, I will need to check piston clearance tolerances. Any tips on how to do this?




Tank is pretty much done. I need to take it somewhere for finishing prep and paint. Decided I am not interested in attempting that aspect myself. Here are just a few size comparison photos next to a stock CB360 tank.



New tank is somewhere around 4.8-4.9 gallons compared to the stock 2.9 (2.8 with the dent on the other side of my old tank, hah). Measured that with a kitchen measuring cup, so it may be a bit off the standardized gallon.

Got it in one.

Mic the pistons and the bore and then subtract one from the other.  I can't remember off the top of my head, but the exact procedure is listed in the manual along with the specs.

Have those same splash plates in my 1966 CA95's engine case below the crank.
"Quality . . . you know what it is, yet you don't know what it is. But that's self-contradictory. But some things are better than others, that is, they have more quality. But when you try to say what the quality is, apart from the things that have it, it all goes poof! There's nothing to talk about. But if you can't say what Quality is, how do you know what it is, or how do you know that it even exists? If no one knows what it is, then for all practical purposes it doesn't exist at all. But for all practical purposes it really does exist."

That plate is called a windage plate or windage tray. It's exactly what you thought it was - to keep sump oil away from the crank throws, keeping as much oil in the sump as possible. It'd take a considerable amount of power away if those crank throws were sloshing around in oil.
