Clutch Damper Function and Stainless Clutch Line How To - Write Up

I have been experiencing the somewhat common "squeak" coming from the release fork rattling against the slave cylinder. The noise only happens when the clutch pedal is out (clutch is engaged), and as soon as I put some pressure on the pedal, the sound will go away. If the car is running and I look under the hood I can see that the release fork is vibrating and when I steady the fork with my hand, the sound goes away.

So, the common solution to the problem that has been suggested is to grease up the area where the slave cylinder comes in contact with the release fork. I have tried this method with little to no results. I have also tried to adjust the clutch pedal so that the right amount of pressure is applied when the pedal out with minor results at the cost of making the clutch feel very awkward. I have also gone to the trouble of changing the release bearing (or throw out bearing) with no change at all.

So after being thoroughly annoyed, I started to think about what else might be causing the problem. The release fork is vibrating against the slave cylinder, and if enough pressure is applied to the clutch pedal the slave cylinder will "dampen" the forks vibrations. So, is this the intended function of the clutch damper? Could replacing this be the real solution to the rattling/squeaky release fork?

Clutch Damper is the cylinder looking thing located in the upper and far left of this picture:


thanks

I am guessing that you mean I bend the fork so that the contact point is closer to the slave cylinder?

My guess is a bad slave cylinder (if never replaced).

I would NOT try and bend the fork or adjust the master to change this. Under normal conditions, the slave cyl pushrod should contact the fork with just enough pressure to prevent it from vibrating.

I just finished replacing the slave cylinder in the hope that that might fix it....no luck though.

How old is the clutch? If the clutch is too thin, that would explain the distance between the slave's rod and the release fork.

Update: I swapped my master cylinder and there still is a problem somewhere.

Symptoms: In the morning the clutch has some free play and the clutch engagement is somewhat close to the floor. After driving for a while the pedal gets more and more stiff and the engagement moves farther from the floor.

This sounds like a leak somewhere but I haven't found one yet. I looked into the honda-tech thread running a straight stainless braided line from the master to the slave cylinder. Here is a link: Clutch Damper Removal

This simplifies the clutch system and I think it will help determine where my problem is. Has anyone on here done this and have any comments, suggestions?

Well after some looking around I found a website that has everything you need to do this for a little cheaper than summit racing.

I used AN Plumbing
Here is my parts list:

Part# Description Price
9919BFE Metric thread male to AN adapter male. 7.99
609104 Speed-Seal Non-Adj. Tube 90 Deg Steel hose End (Use Speed-Flex Hose) 9.04
600104 Speed-Seal Straight Hose End. STEEL zinc plated (Use Speed-Flex Hose) 6.04
600004 Speed-Flex Hose, -4 for Clutch systems (Teflon Liner) 3.45/ft 20.70
9919BFB Metric thread male to AN adapter male. 7.99


Parts Total: 51.76

We will see how it turns out...

Stainless Clutch Line How To

I put off this post since I had the pivot bolt break on my transmission and I had to replace that. I don't believe that it had anything to do with the new line and the removal of the clutch damper.

So here are the parts that I ordered:
Part# Description Price
9919BFE Metric thread male to AN adapter male. 7.99
609104 Speed-Seal Non-Adj. Tube 90 Deg Steel hose End (Use Speed-Flex Hose) 9.04
600104 Speed-Seal Straight Hose End. STEEL zinc plated (Use Speed-Flex Hose) 6.04
600004 Speed-Flex Hose, -4 for Clutch systems (Teflon Liner) 3.45/ft 20.70
9919BFB Metric thread male to AN adapter male. 7.99


I think that I should have ordered the low profile 90 degree hose end instead because the one I used hits the firewall just a little. You have to remove the Master cylinder in order to remove the line.

Low Profile Hose End:


Hose Assembly.
I printed out some instructions that I found online but here is a quick overview.
Put the hose through the first nut.


Then Separate the braid from the teflon tube and insert the fitting.


Insert the hose end into the tip of the hose and then tighten the first nut.

and


Do that to both sides and you have assembled your hose.


Installing the fittings:
This is pretty simple, just tighten the AN fittings into the Master and Slave cylinders. Note: Again, I had to loosen my master cylinder in order to install my 90 degree bend.

and


Running the Line:
It was easiest for me to run the line from the Master Cylinder because its hose end was not adjustable once it was assembled, whereas the orientation of the straight fitting to be installed on the slave cylinder does not matter. I ended up modifying all stock hose clamps from the old hard lines so no additional hardware was needed.

So from the master cylinder I ran the hose over the brake booster to the clamp that previously held the hard line.

and


I ran it under the throttle and cruise control lines to another clamp that held the hard line.


From there it runs where the hard line was making sure not to come in contact with anything it would hurt (it is pretty abrasive). It comes out beside the rear motor mount and is held by a clamp on one of the shift linkage mount bolts.


I wanted to make sure that the shift linkage was not going to rub on the line so I used another clamp where the old hard line and soft line met.


Then I ran the line around the electrical connections and down to the slave cylinder.


Obviously then I had to bleed the system.


Impressions:
The pedal feels a bit more mechanical. I can feel some of the vibrations while shifting. I also have ES motor mounts so that is somewhat to be expected. I have no complaints and now the pedal much more consistent. It may have saved a pound or two considering the new line weighs under a pound and the damper is surprisingly heavy.

Any feedback?

92preludesi_TX: do you still have this Prelude? What have you thouht of the clutch response/performance and the performance of the master cylinder/slave cylinder and the whole hydraulic system?

I just removed the damper on my '01 SH and I am very happy with the feel and response so far.

Thanks

Wish I thought of this before doing the manual swap.. running the hard line is a PITA!
