Topic: CB360, Not as Bad as I thought, stator question though

[Burke]

When I bought my Cb750F the guy threw in a CB360 for an extra $25.00 he said the engined was seized and the stator was cracked.

Since my CB750 is having some frame work done, I decided to tear in the CB360, I taped the kick starter with a rubber mallet and it moved, so I thought the oil I shot in the cylinders did the trick. Then it stopped. The chain was so rusted that it was binding between the drive socket and the "guide". Once I removed the chain I dry tested and wet tested compression and wet they tested 150+.

Then I removed the stator cover and looked for damage, I could not see any .
The rotor looks like something dragged acrossed it but looks ok. Is there a way to test the stator off the bike?

If the stator is good to go, a few gaskets, paint, and a rummage through my spare parts bin, I should have a running CB360.

Cool !!   What year?  The 74/5 had bad cam chain tensioners.  Most guys didnt like the 360 but I love mine now that its running good again.

I just lifted this off ........Do the ton site........might help for testing your stator


"On the plug that comes out of the stator there is 4 wires one of them is green and red don't worry about that one.  On the other 3 you take a voltmeter and you put it on the ohm setting and test them 1-2 1-3 and 2-3.  You should get 0 or close to 0 resistance on all 3 of them. If you get 1 or higher it is most likely bad.  This all info I read on the internet but it pertained to mine."

It's a 74'.

One of the "real" old timers knows of the recall for the tensioner.  I guess it the ser # on the engine has * stamps it was replaced.  Might have been replaced with out stamping.

[Green550F]

All 3 wires should "look" shorted together, but be isolated from the frame. the 4th wire is a neutral sense switch. it grounds out when in neutral.

[Burke]

I have a pink, yellow, white and on with a redstrip wires coming from my stator.  I will assume that the stripe wire is the ground.

And I am finding out that I am not that familiar with using a multi meter .
When I put  my MM (it is a Blue Point) on the ohm setting there are two options, one with "H", or "AT"  My manual says nothing . Which one is the correct reading?


 

[Burke]

Ok...I did a little research and found out out how to properly use my MM.

I was getting an average reading of 1.2-1.7, but after I cleaned the plug ends with som contact cleaner, the reads averaged around .7 would this be satisfactory?

[Burke]

I have now truley inspected the stator and rotor, the rotor has a crack near the bottom and it looks like the starter clutch has some damage. The clutch is loose and I can see the screws, they are loose.
If I pull and tighten everything up, will it be functional?

Or would I be better off finding one on e-bay?

[cb650]

I'm no help.  I've only been kick starting mine for the past 5 years and it charges good so never had to play with it. 

[crazypj]

The crack on rotor is on the back/edge?
If so its a common fault, and its only the starter clutch outer steel case
 You could remove it completely or replace it, three #3 Phillips flat heads hold it on, pull rotor using rear axle (if you don't have Honda puller)
I sent one to Australia last year, leethal is on this site, he's on Honda twins as well.
 0.7 Ohms is OK for stator as long as it doesn't show continuity to ground (probably OFL on Blue point meter, any numbers mean it's shorted)

Cool thanks.
I will try to fix it.
I did not show anything on the ground.
To remove it, do i just theard in the rear axel and pull it off?

[crazypj]

Yep, unscrew 14mm head bolt and screw in axle.
 Should pop right off.
 Screws on back may be loose, usually they are damaged on threads but come out pretty easy
 If you need starter clutch I have another one, they come up on E bay pretty regular as well

If you decide that you're going to go further with the engine and want to know the details surrounding the tensioner (and other) updates, let me know.  I have copies of the factory service supplements and parts lists.

By the way, I have a 360 in the stable and found it to be a fun little bike.  Best of luck with yours.

[Green550F]

Sounds like the Stator wiring is fine... The red striped wire isn't grounded unless you are in NUETRAL! it is connected to a switch outside of the alternator housing.

The rotor is a magnet. as long as the crack doesn't cause a structural issue it wouldn't hurt too much. The real risk is if it could seperate at 9,000 RPM.

[Burke]

I took the rotor off using the rear axel (thanks crazypj) and found that the screws were stripped and the damage was pretty bad. Broke screws, stripped and the cracked piece is loose.

I am going to look for one and replace.
 
Thank for all your help guys.

This is why i love this forum!

[crazypj]

So you only need a good starter clutch or are the screw holes in rotor damaged?
Should be hundreds out there, pretty sure CB350 is same as 360

PJ

[Burke]

Yeah, the screws were stripped in the rotor. I found one cheap on e-bay.
I should be good to go later this week.

Once my frame and engine is done-up, I will start a "Project thread".

Thanks for all your help guys.
