76 CB360, Cherry Bomb at Barber's

Re: 76 CB360, before & after

After PJ told me to double check for hidden bolts under case...
I found these two Ninja A-Holes hiding and giggling at me.

Re: 76 CB360, before & after

You may need to take the second (neutral) detent out of top case.
Bend back tab washer and unscrew it, then find the spring and ball bearing.
If you are not removing shift drum, leave things alone though
BTW, it's much easier to re-bulid everything into top case, make some sort of stand so studs clear

I think that is the best damn advise I have heard in a long time. Wish I would have thought of that when I split my CL175 case.

I dont see an oil seal on that listed in the manual. So, I think its best to leave all that as is. I would like to replace the O-ring on the spring/ball "cap" screw though. So, I will open that up, clean and replace. BTW, It seems carb cleaner would be best for this stuff. what do you think? Because its more lubricating than brake cleaner. And will be much less harmful to o-rings and seals. Or, is there a cleaning product you prefer?
I chased all the hole threads w taps by hand, in order to remove any old sealant, corrosion & contamination and used the carb cleaner to flush them.
Also, anyone not familiar using taps. Be very very careful chasing threads in aluminum cases. ONLY BY HAND nice and easy. AND make damn sure you have the correct size taps. and absolutely sure your not starting them crooked & cross threading.

I also managed to drill out the "journals which cannot found". they were just over 1/16 now just a smidge under 3/32 (.0938)...I lost that bit, so I used a .092 which is weird cause .092 size wasnt listed on my chart as cross ref for any size...at all! cheap index.
I used the dremel. it could get in there decent w out removing head stud.
 
Re: 76 CB360, before & after

I tend to use diesel for cleaning then carb cleaner to remove residue where needed (then brake cleaner where you using sealer on case halves and cam cover)
 
Re: 76 CB360, before & after

also intend to use STP for assembly...must be good everyone I talk w uses it around here.
 
Re: 76 CB360, before & after

So, here is where Im at.
bench.jpg


Now, preparing new cam chain, cleaning. installing new seals, STP everything. and reassembly of the crankcase....No more holes to drill? Nothing else w the crankcase?
then hone jugs, measuring new ring gaps, lap valves...etc
 
Re: 76 CB360, before & after

Honed jugs...there was nothing to it.
I ran drill a med/slow speed and then decreased rpms and increased in/out and it put a real nice cross hatch in em. maybe 45 seconds from each side. I was hoping it might show up in pic a little better. also I can see a little ring wear at the top. (in the pic it looks worse than it does in person.) I can barely see it.

Re: 76 CB360, before & after

OK I found a discrepancy in my new rings!!! Now WTF? CAN I USE EM? Like I dont know that answer...or just go with the originals. even they have plenty of life left.

The width of original is 2.96mm
the width of new is 2.56mm
its a difference I can see w my eye. 0.4 mm
thickness, they are correct.

installed in cylinder its great. .016 gap right and .018 gap left. the original ring in left is .020
service limit is .0315

Re: 76 CB360, before & after

I dont know why I even check shit like this...I should just blindly throw crap together and go! Like an ordinary, happy, drama and stress free moron. Then wonder why it failed...later.
Here is where I got em...seller Dream305

Re: 76 CB360, before & after

Could be you're comparing a top ring with a middle one? Check for a bevel on the edge.
 
Re: 76 CB360, before & after

Are the rings thinner or narrower?
If they are good fit in grooves, don't worry.
Just make sure you fit them in correct order.
Top is chrome faced, middle has a very slight bevel, oil ring has two rails and an expander, fit expander first then stagger all the gaps. The ends of expander are butted together, make sure they don't overlap
Any markings face towards top of piston
 
Re: 76 CB360, before & after

nope I checked em both...and the new rings measure the same. I can tell the new top ring has the softer edges and the middle has the bevel. Just like it shows in the manual.

they are the same "thickness" as originals. they are narrower. width wise. if you stare at the pic I posted you can kinda sorta tell the difference.
 
Re: 76 CB360, before & after

Yep, 'this side up'
Pic looks like top and middle ring
 
Re: 76 CB360, before & after

I believe they will fit "deep enough" in grooves of piston. once installed. I just didnt know if they might be more prone to cracking once employed, (maybe even a little more flexible, less prone to crack). it should make them easier to install on pistons.
