Oil In Alternator Housing?

Postby New2Me74 » Thu Mar 18, 2010 7:34 pm

New to the forum, new to bike riding. When I purchased this Honda 74 CS360 for fuel savings it started right up & ran for the previous owner while I looked it over. Several days later (of course after I had already paid for it) I didn’t get so lucky. It started but reluctantly & it wouldn’t stay running for very long. I started with checking the plugs to see if they were wet & to see what kind of shape they were in. They were wet (so I am getting fuel) & they were in good shape but one of them had stripped threads which I am sure wasn’t doing the compression in that cyl. any good so I had a friend of mine put a helicoil in it to fix that problem. While I was checking the points I noticed that oil ran out of the alternator housing as soon as I loosened it. Is there a seal back in there or do I have more drastic problems like cracked block? I see the starter chain back in there so is this area supposed to be lubricated?
Thanks in advance,
Jason

Thanks L.A.B.
After seeing the starter chain & a veiw in my Clymers Manual that showed what appeared to be a port where oil would flow through I started feeling a little better about oil being in there. I just thought it was odd for an alternator to be submerged in oil. Whew thats great news. Now I just need to get the head put back on from where I had the helicoil job done & try this one more time.
Thanks again,
Jason

"New2"

Very common for Alternators to be immersed in oil ~ For example my Commando and the Trident are all wet ~ debatable perhaps as to the virtue of such as hot oil probably only serves to be detrimental to electrical cable/s ~

And there is very few moving mechanical parts that do not require some form of lubrication ~

Thanks SS,

Like I mentioned above I am new to working on cycles so I had never seen a wet alternator before. It just that most of the time electricity & liquids don't mix. Maybe thats why I keep hearing about how poor the charging systems on theses old Hondas are. But like I mentioned to LAB this is great news, now I won't have to tear into it further to replace a seal or worse deal with a cracked block.
Thanks again to both of you,
Jason

Yea like LAB said, you are in the clear.

Make sure you have it on its center stand while you have the generator plate off: the oil is free to leak out if you let it over on the kickstand!
