Need help with hydro clutch

Route62 · Post by **Route62** » Mon Jun 20, 2005 5:49 pm

Just did an overhaul on a 1600 DP stock setup. Its mated to an IRS trans. Put in a new flywheel, gland nut, clutch disc plate, new late type clutch plate with those finger type springs, new throw arm, throw out bearing, new bearing spring clips, and new slave cylinder, and bled. I think its safe to say everything that could be part of the clutch has been replaced.

So put it all back together and tried it out. I can shift into all gears when engine is not running. Shift linkage is all new. Start motor up step on clutch, verified that slave does move arm, and when I try to go into first, grind! Same in all gears. The clutch does not seem to be doing its job.

How tight should the clutch pedal feel? It moves the arm when you press the pedal but does not need much force to do it. Is the throw bearing not pressing the spring on the clutch plate? Any other theories?

Just by looking at the geometry of the clutch arm, it looks like there's too much clearance between the release brg and pressure plate. Moe the arm by hand, and see hoe far it moves. I would think it will adjust out assuming the hydraulics are bled properly.

P.S...good looking setup, bro.

Thanks Noof,

So your saying undo the two nuts that are jambed together and pull the slave and arm back some, tighten it all back up so now the bearing would be closer to the pressure plate. Sounds like that may be it. I also will rebleed the setup so that I can make sure that is not it.

Should I just play with the setup till it works or do you suggest a starting point for the throw arm? Straight up and down?

I would move the clutch arm forward untill all clearance is removed between the release brg and pressure plate. then, turn the adjusting screws untill most of that freeplay is consumed. then try it. It should then feel like a clutch.

I have seen your bug pics at the Samba before... correction drooled over the pics at the samba! Beautiful ride Noof. Are you in Canada? If you get tired of riding in that bug I'll trade ya and you can go open air!

I am not sure about one part of this. I understand waht you mean when you say get ride of all the clearance between the brg and plate, but then you say turn the wingnut till freeplay is consumed. If I have already got the brg and plate clearance consumed which freeplay are you refering to?

If you can't move the arm forward at the top, then the freeplay isn't the issue, but by the pics you posted, it doesn't look that way.

Man Noof you may just be a life saver. I about rolled this rail down a cliff yesterday when I could not figure this out. I threw every tool I had in the garage ou in the yard, still finding some today!

Ok so, get rid of all the space between the brg and plate, then play with wingnut till any freeplay is taken out so everything is right and firm,. One last thing how do I know that the bearing won't be riding on the plate. I assume ther has to be a little clearance between the bearing and plate when not switching gears. Should I just get it all to work then back it off a mm or so?

Take out all the clearance you can feel by hand, and see if the clutch releases. If it works good then, back the adjuster off untill you feel a small (very small) movement
