Topic: Starter quealing on CB350

[oconnor]

Nasty, nasty screaching, almost like it doesn't always engage. Then the next poke it is fairly normal. Ideas?

[seaweb11]

Well.......no one seems to want to jump in, so I will. 
My experience comes from the "CL350" I did last year.   It has a very funny squeal when it starts up. Not exactly a gear grinding noise, if it was I would look a bit deeper.  More of a squealing noise. I don't know how to describe an irritating noise sorry

It freaks out the wife, I just hold the button and get er going. No harm done. 

Did that help?  doubt it

.......think I should look in to that noise?
.............to funny to realize the same problem..................... at the end of a reply.

I'm out a here...can't beat that one tonight

Dunno but replacing the starter on a 350 is an involved task. 

Kick it as much as ya can

Either the rollers in the starter clutch have flats on them or the motor bearings are dry and seizing up. It should be easy enough to get a complete assembly. You have to remove the generator rotor to change starter clutch ( I guess this is a 350 twin?) On a 350 four its an engine strip to get to starter clutch

Yup engine has to come apart on a 350 F. hence the involved task 

[oconnor]

This is the twin, sorry for the confusion. Sounds like dry bearings , or what I think dry bearings would sound like. Are the starters serviceable?

[cb350twin]

Mine dose that too.. Starts just fine though except for the sound  that you would hear if you ran over a pig Its been that way for a while starts strong and steady dosn't really bother me

[seaweb11]

That's the noise "a squealing pig"

When I bought my CB350 twin the starter clutch would engage some times, won't the rest. As I planned to do a full rebuild I didn't bother too much. Turned out somebody didn't lock the bolts that fix the roller cage with the rotor...










I wouldn't say your problem is the same, but a check would be in order. You have to empty the oil, remove the rotor cover, extract the rotor -Bryan Jones gave me an invaluable advice about using the rear wheel axle, you can buy an used one out of eBay, will be cheaper than the extractor and you will have a spare axle...- and check it out. When I put the new bolts on i used allen head bolts and mashed the heads on the groove to avoid them coming loose. Can't say more because the engine is still in the bench waiting in the middle of my "to do" list...

You can see in the pics where the roller track ramps have cracked. The outer steel cover is all thats holding it together (for now )
I've got CB360 one if you need it ( may have a CB350 one but dont remeber where I put it)
I think they are very similar in size on most models that use them.
Usually, when the bolts come loose it sounds like  the big ends are knocking

Crazypj, I don't think I fully understand you. That chunk of metal is not cracked at all. There are some grooves in each cage but there is no crack. Otherwise, even with the metal cover, it would have fallen as soon as I get it. I mounted it a while ago and I don't feel like dismantling it again to make sure, but I'm positive I wouldn't have overlook a crack, much less three.

Furthermore, I checked correct operation with the finger and it works (engage in the right direction, disengage in the opposite direction). If you check the bolt lenght, old vs new, is different. New ones are according to parts manual, so I'm starting to think somebody dismantled the clutch sometimes in its life. I had proof -gasket sealant- that proves the engine has been opened, but don't know wether completely or just the top end...


If you don't mind to show in the pic what you say is a crack I would greatly appreciate it.

For what it's worth my 1972 CB350 K4 had 5865 miles on it when I got it 5 yrs ago, it will do that same thing every once in awhile.  We have 10000K approximately on her now and still screaming when it cold winter riding, California cold 50's. She continues to start first time everytime, it's a HONDA!!!

Hi Raul,
Had a better look at the pictures,  its machined grooves.
 Its just where the cracks appear though, maybe they crack because of the machining?
It usually takes a while to become noticeable as the bolts will hold everything together , the parts just pivot a bit and push out against the outer shell when starter is operated

Crazypj, for the life of me that I can't see the cracks. Could you do me a favour? Save the picture in your computer, open it with Windows pain, circle in red the crack and attach it to your response. That way I would be able to know which crack you are talking about.


Thanks in advance

Hi Raul, as soon as I put the picture into paint shop and enlarged it I could see there is no damage to your starter clutch.
 I have seen them break so I assumed the machining was damage. Maybe my previous post didn't clarify this well enough?
Anyway, I'll try and post pic I saved and modified for future reference.

[Raul CB750K1]

Thanks for the input, I appreciate it. Those were the grooves I was talking about, and I'm 99.99% positive that should have been a crack I would have noticed it... I was getting paranoid trying to find the crack in the picture!!!
