[How-To] Clutch Damper Valve Delete


Recommended Posts

It's actually very common on Japanese cars. My 2000 Infiniti G20 had the damper too, I bypassed it when I installed a new stainless steel braided clutch line, no flex at all anymore in the clutch hydraulic system :lol:

Same thing on my R32 GT-R (same "fix" as well after the rubber hose split).

On a scale of 1 to 10, how hard is this. i have an estimate of $260.

 

Is there any mod which i can add while he has everything apart that makes sense?

 

I have to buy the correct tools which i see on page 1, but that is less than $50.00, but i only use once.

Glad I stumbled on this thread. Funny, the first time I've ever heard of a clutch damper was just the other day.

Watching a video of this guys 20B RX7. He showed where he actually added a damper in the clutch line b/c rough engagement with his beast clutch.

Well due to the cost and the technicality, i may be have CD for a while. But at least one person sees it as being useful. When everyone agrees on something, i begin to worry.

 

I'm from Las Vegas, so when everyone says this team will win, start looking at the other side.

In this case tho, the other side is premature clutch wear. I guess if you don't plan on having your car long then maybe this won't matter? If you've driven manual transmission cars for awhile, then I guess I can't see how youre ok with the floaty clutch engagement point. All the benefits of the delete have been stated here so I won't repeat myself, but doing this mod definitely makes shifting better.

Make an appt with Gteaser's garage and take a mini vacation to California, lol! I think he has done a few of these.

 

 

But really this part is not hard to install, a pain to get to, but otherwise pretty straight forward. If you diy, make sure you purge out the line of fluid before you break the fittings loose under the dashboard. Do that and there is almost no mess. Have a can of brake cleaner on hand just in case, it deactivates the corrosive properties in brake fluid in case it gets on anything.

It's really not that difficult at all. Just uncomfortable for a little while... No need to pay someone to do it; Just lay down a towel and and be careful not hit the clutch while you have the lines disconnected.

The first page mentions special tools and bleeding lines which I have no experience. I can see me attempting to drive and the clutch won't engage. If I can get it done for 100 bucks it is well worth it to be done right.

 

One has to know his DIY limits. *chuckle*:lol:

I used a Mity Vac self bleeder which was super super easy. First time for me and only took 5 minutes. Pedal feels better than before I started. No reason to raise the car.

The first page mentions special tools. Did you need any?

No "special" tools really required. All you need is a wrench/socket for the mounting bolt, a line wrench for the lines (could use a regular one but a line wrench is better), and a fluid vac or a 2nd person to help bleed the system. It shouldn't take more than an hour to complete the job.

I have done 3 of these, my car, amidroc's car and swannee225's car. Actually swannee225 did most of the work himself.

 

You for sure need a quality 10mm flare nut wrench for the flare nuts on the hydraulic pipes. That's the only "specialty" item I had to use. You also need a 10mm box end, a length of 5/32" clear hose and a jar to bleed the slave cylinder. Other than that, all I needed was a bench grinder to cut the gusset off one side of the union. Some people didn't even do that, but I believe in making things fit and function perfectly as if it was designed that way originally. I think I also used a turkey baster to get as much fluid out of the m/c reservoir as possible first to minimize the mess in the footwell.

 

I was able to easily bleed the system with the help of a friend pushing the pedal and pulling it back up.

 

Make sure not to let the reservoir run dry while bleeding, or depressing the clutch pedal until you get the entire system closed up after the install.

You need a flare nut wrench. Don't use a regular open end wrench on the hydraulic hard lines, you'll round it off and then you're screwed. You don't need the bleeder, just a friend. If you have a 10mm box end, and a 10mm socket, you can do this for less than $10 in new tools.

eh, i definitely wouldn't say you need the flare nut wrench i did it just fine with regular spanners. i actually bought a flare nut wrench to do it and just fiddled with it for 5 minutes before asking myself "why the hell do i need a flare nut wrench? this thing looks like it'll come off with a regular wrench just fine" and it did.

For lines inside a car, you're probably right, but a flare nut wrench is better. Gets you way better engagement on more flats, so there's less chance of rounding off the nut, and you'd need at minimum a hacksaw and a flare tool to recover from that, if not a whole new line.

You go a head and play with fire then sonny. :lol: I would never use a regular open end wrench on a hydraulic system flare nut. You're asking for trouble because the first time that open end wrench slips off, you're past the point of no return and a flare nut wrench won't even work for you, you're relegated to vise grips, cursing, mashing the fitting and leaks upon reinstall. I can't stress enough the importance of proper tools.

Wow. I am so biased against dealerships that I forgot about them.

 

I'll email my contact there and see what he says. Thanks "Z"

 

Dealer won't do this job. I might attempt when I have a couple of days, a backup car and the proper tools.
