Postby roadwanderer2 » Tue Apr 19, 2016 11:27 am



is there a "how-to" article on bleeding the hydraulic clutch on a GL1200 SEi, or can someone please as least let me know where the hydraulic part of the clutch on the engine is located. i cant find any info on it in my repair manuals.

are you talking about the slave clutch? on my 84 its on the back of the engine near the connection of the A arm. Google how to bleed the clutch on google. Steve Sauders has a step by step on how to bleed the clutch. Better results if you do it at the handle bars at the banjo bolt. I just rebuilt my slave clutch and the only results are at that location.

i just rebuilt my master and slave clutch. I tried everything. It took 30+ bleeds to get it right. Then would creep forward with the clutch lever pull in. So had to bleed some more. In other words its APTA after rebuild. But just to bleed while replacing fluid not so bad if not rebuilding. :D

yes, from what i understand there is a slave clutch on the outside of the clutch housing that occasionally has to be bled, so i need to find it. its on an '86 1200 SEi.

well, with the knocking sound i get when i start it up cold then pull in the clutch, maybe i can stop that by bleeding the slave clutch.

i send you some pictures of where it is located. in the mean time if you get eye level to the rear break pedal. Look at the rear of the engine and you will see it on the back of the engine. It should have a hydralic line running to it and 3 each 8mm bolts attached. about the size a a pop can lid and narrow so it can be removed

If you go in from the left side like my 85 to bleed there maybe a block plastic canister to remove. (1 bolt holding.)

that bottle collects the fluid from the separator tank which is under the jocky box in the fake tank. You're supposed to empty that occasionally. Removing that allows you to get to the bleeder on the slave. I just rebuilt mine while I had the engine out and it shifts much better. Be sure to have the handlebars tilted so that the banjo bolt on the master is below the fill tank. While you're at it, inspect the bushing in the handle for the push rod on the master cylinder. That bushing wears and can cause creep and at worst, not being able to shift. I just replaced mine yesterday and it moved the clutch release point way out from the grips. This means it gets full movement to fully disengage the clutch. It's a cheap part and takes maybe 10 minutes to do.

I'm going to stick my neck out here and say that if you need to bleed the clutch then you have a problem.Properly sealed hydraulic clutches or brake systems for that matter don't just develope air in them.In your case I would definitely rebuild at least the slave cylinder.You can get a kit for less than $20 or at least the last one I did was and not a hard job.I'll bet there is a trail of brake fluid at the bottom of the cover where the weap hole is.You may also have to do the master cylinder as well,but in my experience you can usually get away with just doing the slave cyl.
If I'da known it would last this long,I'da taken better care of it.

Fatwing, i didn't say i "needed" to bleed the clutch slave, i was just thinking that it might help to get rid of noise i have when the bike decelerates given the fact that the noise tends to go away slightly when i pull in the clutch lever, and how can i say this.......when the bike is rolling and theres that "sweet spot" between power and balance with the engine and speed, the noise goes away completely and once back on the throttle or deceleration, the noise is back again which makes me think its in the drive line somewhere.

Did you ever look into the clutch release bearing ( throw out bearing) or was that someone else? They can make different noises at times.

hey twocams, no, i haven't gotten that far into it yet, im still doing some research on the bleeding procedures at the moment. im having a little trouble opening up the clutch m/c, seems i have to move the entire clutch perch to get to one of the cap screws. its too close to the switches that are mounted on the left handlebar.
