How to bleed a clutch?

Postby Bigevilone » Tue Apr 13, 2010 6:30 pm



I have a 1986 goldwing GL1200 aspencade the clutch stopped working on the bike and after checking found out the fluid for it was low (before which I was not away it had a hydraulic clutch as my last wing had a cable) I have since topped off the fluid and it has not leaked or anything but I still have no clutch. I talked with my normal repair shop and they said that they can get low and now just has air in the line probably. This shop has since gone out and is currently looking for a new location. My problem is that I cannot find the bleeder valve for the clutch system. I have been trying to find my repair manual for it but with young kids it could be anywhere atm lol. If anyone can help me by telling me where to find the valve or if this bike even has one it would help me greatly. If the bike does not have a bleeder valve the any suggestions on how to bleed the system would help also. I found a post on this site on how to replace the clutch cable on the wings and taking the location of where the cable goes believe I have found the fluid line now but am unsure, it is just a hose that goes down to the relative location of where the cable would normally connect and just has a bolt / nut holding it in place to the case. if anyone can give me any light on the subject I thank you the riding season is here and my wife and I would love to go for a ride but here we sit because of this problem. thanks for your time people

From the 1200 service manual:

Air Bleeding

Note: Check the fluid level often while bleeding the clutch to prevent air from being pumped into the system

Bleed Valve
Bleed Valve


1. Squeeze the clutch lever, open the bleed valve 1/2 turn, then close the valve. Note: Do not release the clutch lever until the bleed valve has been closed again.

2. Release the clutch lever slowly and wait several seconds after it reaches the end of its travel.

Repeate the above steps until bubbles cease to appear in the fluid at the end of the hose.

3. Tighten the bleed valve to 35-61 inch-lbs.

4. Fill the fluid reservoir to the upper level.

I figured my 86 aspen out. Air will hide up near the handle bars. Remove clutch master from handle bars and hold it up then shake and pump it . The air will work back up to the resevour. Laying the bike on the right side will also work . You need to get the air past the banjo nut on the master. If you pinch the hose up near the master and still have weak or no pressure the problem is up top.

An easier way is to drape cloths under the master cylinder to catch any drips, crack the banjo on the hose loose and pull the lever, tighten the banjo prior to allowing the lever to return.
This will expel any air bubbles.

GREAT Info!!!! Like the original poster, I would never have found the bleeder valve w/o the picture. Was a bit tricky trying to bleed & hold the clutch handle but it was doable. Bike on the center stand, lay on your back, using your right hand place wrench on/open the valve 1/4 to 1/2 turn space permitting, using the left hand squeez the clutch handle(Watch not to get brake fluid in your face/eyes), close/tighten the valve, release the handle. Repeat as needed & remember to check the fluid level. Mine took twice.
After bleeding, I was able to ride off with out any problems from my '85 Aspy. Many THANKS!!!

Replace the bleeding nipples with speed bleeders, a lot easier:

figured I would jump back to post an update, between the information all of you gave me (much thankfull for) and some research, I did discover that my bike does not have a bleeder valve on the clutch system however I have been riding again since my first post thanks to you guys and the cracking the banjo nut by the handle bars trick that worked great (although a bit messy) a friend of mine stopped by and agreed to help me with this for the simple fact that while holding the handle bars so that the master is at the high point, then holding the clutch handle in, then having to take the wrench and crack it loose which was pretty tight, I just ran out of hands by myself, I would suggest to anyone that does try it this way to cover the bike as was mention and wear eye protection. Each time we cracked the nuts we had fluid shoot everywhere so the covers helped the bike didn't do much for my windshield though. But after doing said steps about 3-4 times clutch is now working fine and running strong as ever so thanks again all, ride safe.

If your clutch slave cylinder doesnt have a bleed valve someone might have broken it off. It is on the left side accessible when the plastic drain container is removed

I have to ask, since no one else did, where did the fluid go? That is a closed system so in theory it should never be empty. I would get a good flashlight and snoop around down by the slave cylinder trying to spot a leak.

I had the same question about the fluid also as it is a closed system, however I had never actually checked the fluid levels on the clutch since I bought the bike and I asked the normal bike shop that I took the bike too about it also the mechanic there had said the over the course of time that the fluid can evaporate or break down ect something along those lines too, that the fluid levels for the clutch should be checked periodically. Again I never checked it as up until the point of the problem I didn't actually know that it was a hydrolic clutch as my last wing had a cable for the clutch. Either way if that was the case or not, I am not sure but I have had the bike for a few years here and that is the first time the clutch has ever given me an issue but I am watching it now just to make sure that I don't loose any more fluid over time, will try to keep an update as it goes.

Thank you all, thank you, thank you. I was having a heck of a time bleeding the clutch. Kept trying over and over and couldn't get any pressure in the system. Read the hints here about bleeding through the banjo bolt. Two quick tries and BINGO - back in business with a fully working clutch. Love the site!

I agree with Tricky's system. Air bubbles will tend to travel up to the top of the hose faster than you can pump them down to the slave cylinder. I find it much easier to bleed the air at the top then bleed off the old fluid at the bottom. Works good on the brakes too.

Nice to hear it's working again..... you should try it after installing a new stainless clutch hose.

This is a good way to also bleed the front or rear brake master cylinder's if you ever get air in them.
