Crankcase breather hoses

[rraymond]

Hello,

Tonight, i replace my Cruise filter and gaz filter for my 1993 GL1500 SE. When i do that i saw 2 hoses (lef side) with a plug at the end but one of them was unpluggeg and i dont have any idea where i need to plug it. Does any one know where each of these hoses are plugged? I have a Haynes Owners Workshop Manual and i dont found some pictures to help me about where i need to plug each of them.

Thanks for your help.

If those are the hoses down by the alternator they are just drain hoses. Usually both are plugged and need to be opened and drained occasionally.

They should both have plugs in them:



They are as you mentioned, crankcase breather hoses, and will accumulate oily water over time from condensation, particularly when ridden in wet or humid conditions. They should both be plugged except when draining during maintenance, as otherwise they can allow unfiltered air to be drawn in, or unfiltered crankcases gases to be expelled.

Thanks. But imwant to Know where the other end of each hose are plugged because one of them are unplugged at the other end. If you have a picture, it will be more easy for me to see wher the other end of each one are plugged.

Thanks again.

One tube connects to the crankcase breather storage tank:

The other one connects to the air cleaner housing via a tube joint fitting:

This then connects into the bottom of the air cleaner housing:

Glad to be of assistance, and great that you changed your timing belts. It's great that the articles on the site help people so much! I don't envy you working to get that tube reconnected however. Bonne chance!

I noticed Friday that one hose was hanging down close to ground. When I took off left side covers and took a look, I find that one hose is not attached to anything at top end. Is this going to hurt anything if I can't take things apart to find where it goes till end of riding season. There are the 2 hoses coming from top, but not sure which is for what. I did take the end off one back in winter and drained it, but not sure now if it was the one that has come off. Thanks for any advice I can get. Don't want to take everything apart right now if I don't have to.

Iposted at the end of this thread awhile back but got no reply. I have the left side cover off now looking at cruise sub filter. Where the reverse handle is. I still can't see in there to see where that hose goes. I am pretty sure it is the Air cleaner hose. Since I drained other one when I changed oil and lots of yucky moister came out, I am sure that one is the crankcase drain hose. Is there another way to see in there without taking the carb tray out.
