I like that blue color you PC'd the engine stand,reminds me of many IR air compressors I used to paint in a spray booth 40+ yrs ago when i worked for my Dad..

Never trust your color monitor. It's not blue. It's one of my favorite go to powders called Silver Vein. It's great for hiding imperfections. The frame of my XR is done in it also. I use it often for Candy bases. It looks great under a Candy Blue or Red. This one is Silver and Black.

What part of Ct. are you from? I grew up in Sandy Hook, Newtown. Mom and Dad and 2 brothers still in Ct.

Sure looks blue, silver most likely picked up the blue cast by the sky...Larry

Born and grew up in Stamford,CT. and then our whole family picks up and moves to a snobby island off of Cape Cod,MA. and I spent most of my life on & off from there;it's too small of a place for me and it cost too much.

Ct. cost too much also. 1st or 2nd most expensive county in the country (Fairfield)

noooo, not Stamford....I used to play in rocknroll bands, one time on tour, caught in an actual mild hurricane (The rain was not mild) the back wheel fell off the van scattering brake parts down the highway at 60mph.  We were stranded in Stamford for three days trying to get all the little bits to put the brake drum back together. sucked bad  sorry for the thread jack

Got the tranny out and am waiting on the puller to get the crank gear off and then split the cases. I'm hoping within a week I am in the reassembly phase.

[grcamna2]

That timing case did get plenty of water inside but looks like it's able to be salvaged,possibly only need a bearing change.

[Powderman]

I would argue about "plenty", but there was moisture in there. There's a bit of surface rust on the gears but nothing to worry about. Water was in the crankcase, not the timing case. The water I poured out was pretty clean, so I'm assuming it wasn't in there for 30 years. My sister stored the bike in a horse trailer in a pasture for 3 months last year (Sept.-Dec.). They got some rain during that time so it could have gotten in then. I'll know the extent of the damage if any probably tomorrow when I spit the cases.

[grcamna2]

That's good that it wasn't much for a long time. 
 I've been trying to salvage a bottom end from a Honda single that i got a few months back.I bought it from VA. and it was sitting for yrs. w/o a top-end on it and crank was junk but i was able to salvage more than half the trans. parts.I'm going to use many of the gears even though they're a little rust pitted;I had the teeth sandblasted and feel ok about them.

[Powderman]

everything inside the cases is looking to be in better shape than I was expecting. Once I get the crank out and inspect the bearings I'll know whether I need to order them or not and proceed with the reassembly. One of the bearings in there is $100.

[Powderman]

Eureka, the cases are split. . I was remarkably surprised at how little rust there was in the bottom end, mostly contained to surface rust on the cast flywheel. Should clean up easily. Bearing on the left side looks very good, no need to replace. It wasn't near as nasty as I was expecting in the bottom end.

[Stev-o]

Good news!

Bearing carriers made and arrived today to complete the wheel swap.

[grcamna2]

They did a nice job machining those pieces

Yes he did. The 2 shoulders need to be a couple thou smaller and the bolt holes on the diagram show 11/32" but a 5/16" (10/32") wouldn't go in. I had to redress the holes and chuck them up in the bench lathe and file the clearance to fit in the wheel.
I was able to remove the crank gear and finally drop the crank out of the cases. Time to clean all the parts and start reassembly

[grcamna2]

Does it look like you'll only need to fully wash out the crank assembly rather than rebuild it? That would be nice

The crank has some surface rust I will hit with the rust remover. Actually upon further inspection the rust isn't really an issue that oil didn't take care of. There is no visible damage from water in the bottom end. The chain sprocket bearing is bad, already replaced. Will clean the parts and replace all the seals and start reassembly.

[Powderman]

Stripped and blasted the paint off the cases. Now I have to decide how to finish them. The tins are Jeep Rescue Green and all the chrome on the bike has been powder coated Matte Black. I don't really want mirror finished covers but more natural. Do I do the cases Matte or Wrinkle Black.

[Stev-o]

I vote Matte if vapor blasting is not an option.

[Powderman]

I like vapor blasting but don't know how that big "white" engine will look like in the stealth Matte scheme of the rest. Kind of defeats the effect of matting the chrome. May consider VP for the covers and Matte Black on the cases.

She's a roller for the first time since I've owner her.

Finally got the sludge trap plug out. This was an SOB to get out. It took 10 minutes with the BFH and the impact to turn it 360°. Another 5 or so to get the next 360° and then I put the  1/2" air impact to get it the rest of the way. Plug is pretty beat up from previous work. I'm surprised this bike had so much work done before my brother bought it 2 years old in 72. The plug looks as though the "stake" was drilled out with a too large bit, but in the plug, that is being replaced, and not the wheels. I don't know why this plug needs to be staked when it is so freaking tight going in it needs serious impact tools to remove. The replacement plug is an allen and not a slot.
