I had an OSG clutch installed some time ago, but never removed the 'clutch damper line' ...

Does is make a big difference at all and what is the best way remove / bypass it?

Cheers

Rip it all out and use direct braided clutch line from master to slave. I usually use the Japanese APP ones but just recently fitted one from HEL to the white 32 as they were cheaper and easier to get.

Thanks ... will do ..

Can you tell me what difference it will make? How's the clutch feel afterwards?

I always thought the clutch feel is somewhat 'mushy' that's why I'm looking into the thing

As all car's clutches feel different, even if they are supposedly identical, it's impossible to say what will happen with yours. I did clutch damper delete on mine (just retained the hard lines and did a little rerouting) and I couldn't feel any difference. On other cars I've done it on, it felt nicer, and on some it was bad. Real juddery.

I delete the whole lot, and have a new line from the slave to the master. Clutch kicks at the skid pan felt better, felt it it would engage faster.

However, previously it had unknown age fluid in the line so that could have attributed to it's crappy feeling.

Thanks for the feedback ... I definitely like no 'judder'  .. :) but will give it a go since I always thought the clutch feel is a bit detached and mushy. I think that's the consumer setup to make it 'nice' for ordinary customers ...

Remember there is still the rubber line to the slave in stock configuration, which swells on operation. Getting rid of that alone improves clutch feel, but just simpler to delete the lot. Bleeding is also much easier as it is pretty easy to trap air in the stock damper hardlines.

Changed mine to a quick change line and to be honest I didn’t notice anything different. I’m running a r4c clutch and it feels the same. 
Quick change line is braid it just had a cam lock in the middle, makes taking the box out easy

You wouldn't normally undo your clutch line taking a box out - you unbolt the slave from the box so no rebleed required.

On a GTR you have to remove the whole slave to get front shaft out, then just cable tie out of the way. I am under my car right now, so this is an APP direct clutch line on a push slave cylinder on my dog box.

They're what you get when you put a man engine and man gearbox in your Skyline.

You have such a hard on for the TR6060 🤗

I hate the slave in my XR6. Had to put a remote bleed line on the slave just to bleed it without the box being taken out. They are a pretty good transmission though - hard to beat on the street for shift quality (if your shifting below 5000rpm).

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.

      Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:

      Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"

      But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
