Pulled engine on 1984 GL1200I

Postby t5noel » Sat May 16, 2015 10:04 am



I pulled the engine following a youtube video. It was very comprehensive. I have replaced the stator and rebuilt the clutch slave cylinder. I am torn as to whether to replace the clutch plates. Is there some way to visually determine if the plates are worn? Oh, a little history. I bought the bike at an auction and have not ridden it. The engine started but the clutch slave was rusted and leaked out fluid so there was not any movement of the bike. It has not been on the road for at least two years. I appreciate any thoughts on the matter.

The only way to know if you need to change the clutch plates is to measure the thickness of the friction parts. But dismantling the 1200 clutch is not like the rest of the fours. It has a diaphragm spring, rather than the coils springs of the others, and that is a real bear to get off unless you have the right tools.

Also, while you have the engine pulled, it's a great time to replace the timing belts, which should be done before it's started.

Yup, great idea.
The later B plate (on all the late models from '78) has teeth on both side plates and so is nothing like as bad as the first GL1000 versions with teeth on one side only, but it is still really crap engineering with spring steel fingers held by BRASS rivets. :o

Ok, I'm ready to put the status cover back on. Is the gasket by itself good enough or should I use liquid gasket with it. If so do I put the liquid gasket on one side or both.

one side.....and sparingly! Most folk totally overdo it. Two machined surfaces need very little; really, just enough to hold the gasket in place is sufficient.

Cover side glue other side grease, comes off when you pull cover with no damage to gasket.

I have a question concerning the clutch pin that the clutch slave cylinder pushes on.Should you be able to push the pin in with your fingers? When I push on it nothing happens. There is no give to it.

If you could push it with your fingers, you wouldn't need hydraulics to operate the clutch! You also wouldn't have clutch that worked.

Ok, Thanks! I am learning, though my questions may seem dumb.

See the line in my signature!


Sorry if I offended. I know I tend to be a bit brusque with my answers, but is not because I think your question is dumb. We all had to learn and questions are sometimes the only way.
Think about kids. All they ever do is ask dumb questions! All the time! Is it because they are dumb? Not at all, it's because they don't have the knowledge or experience to know it's a dumb question. What's more, they don't care! They just need the answer.
So please forgive me and ask away!

When you pull the clutch lever in, you're pulling in with about 20-25 pounds of force through an arc of about 3 inches. The lever and pivot translates this to pushing the piston inward about 3/4", applying about 80-100 pounds of force on that little pin.

So if you are able to push that rod inward with your finger, applying around 80-100 lbs of force, you should be able to get it to move inward. Good luck. :)

I would tell you when you put this engine back in make sure you do a good bleed on all of the brakes and clutch. it is too easy to get air in the lines and the only way to get the air out is bleed at the source. The 1100 forum in here is an excellent info on a lot of stuff.
