How To Swap Pedal Box?

Recommended Posts

Hi, guys

My clutch itself is functioning perfectly, but the pedal requires me to push my foot right to the floor before the clutch engages. It's also got a creaky pedal sound, i don't know if that's related.

I've been quoted $100 for a replacement pedal box, and 4 hours labor to install it. I'm very poor at the moment, so thought I'd give it a go myself before giving up and sending the car to them.

I've done searches but can't find any tutorial or useful information. Can anybody point me in the right direction for replacing the clutch pedal box on a R33 GTS-T?

have you considered bleeding it or making sure eithes ctliners isnt shagged? having to push the clutch further is a good sign of the clutch nearing the end of its life also

Have the spot welds on the clutch pedal box snapped? I took mine out and rewelded it. Took me like 20/30 mins to take it out the first time. It's way to easy. Grad a torch and look under there, you will be surprised how easy it is!

easy job.

you don't need to take out the whole dash, just push the seat back as far as you can and you should have no issue undoing the bolts and replacing it

I don't know what you are saying, but i'm happy to check it out if you can explain it to me?

hey man ,

i just had the exact same problem , became so bad i almost had to put my foot through the floor!!! the pedal box is cracked and most likely wont last longer than a couple of months , i was freakin out too thinkin it was gonna be $600 - $700 ( as was quoted ) to fix , turns out its 3 bolts under the master cylinder and a bit of tetris action to remove ( and worse to get back in ) and a pin that runs through the box and the pedal , and boom drops straight out , a bit of welding and strengthening around the weak spots ( mine had 6 cracks and fractures ) , seriously took about 45 minutes of actual work!!!! think about it , so worth it !!!!

i payed the princely sum of.........NUTHING!!!!!!

feels like a button clutch should !!!!! beta than ever!!! STRONGER THAN NISMO ITEM!!!!

enjoy!!!

dspec2, i'd especially love your help on this, can you mark out exactly what you mean?

I have a very mechanically minded friend, and we'd love to tackle this together.

Alternatively, I'd love anybody to show me the bits that need replacing/welding, whatever, just take my pics and draw all over them if you wish :D

Sorry if they are crap quality, it's 12:30 at night so theres not alot of light around at the moment :D

if it creaking its probably cracked and flexing, common problem.

So which bit needs to be replaced?

I'm just trying to work out what needs to be done, i figured that if i worked out how to install a turbo by myself, i should be able to do this, i just don't know where to start :)

Can you link me to a tutorial or information, or point out on those pictures, which part needs to be fixed?

Thanks guys!

Further to what Trent said, you will need to pull the pedal box out and either reweld where it has snapped, or replace with a 2nd hand box, or replace with a Nismo box :)

this is the clutch pedal out of my 32. the spot welds im pointing to are possibly broken on yours. its bolted in three spots, 2 bolts go through your firewall and hold the clutch master on, the third is under the dash you can get to it with a 3/8 rachet small extension an 12mm socket. there is also a clevis pin that is in the pedal that you will need to pull out, its for your master cylinder rod. once the box is out you can either TIG or MIG weld it or buy a 2nd hand unit, or if your prepared to wait a few days get a nismo one from nengun or other supplier

Alright,

I removed the pedal box as per instructions, probably took about half an hour, was done exactly as described: remove 2 clutch master cylinder bolts, remove the pin from the pedal (connecting it to master cylinder), and one final bolt u can get to with a few socket extensions, right above the clutch pedal springs :(

Anyway, now that it's removed, I can't see any problem with it, can you guys take a look and let me know what you think?

Basically, the clutch pedal squeaks (which i guess is tolerable, what lube would u guys recommend), but the main problem was that the "friction point" of the clutch was pretty much at the floor, so i had to put my foot almost through the firewall to change gears, it's totally driveable though, just alot more work than it should be.

Heres the pics, I didn't know what angle was best, so thought i'd give you 7 :( If you want a different angle, just let me know and i'll go take a pic.

I'd love to get this sorted, as I can't get too far without a clutch pedal :(

Hi.

Your pedal box looks like it has been welded before. The welding doesnt look factory. The rb25 painted on it is a fair indication along with the surface rust point to it being second hand. I would buy a good clean unit and replace.

Hey bud,

As far as i can remember Skylines have a hydraulically adjusting clutch. So they should compensate for the wear in the clutch.

But you can adjust the "friction" point of the clutch by adjusting the rod that connects the pedal to the master cylinder.

Just dont get to carried away and adjust it to beyond the point for the clutch fluid to be able to release pressure into the master cylinder reservoir as it gets hot.

If its biting on the floor you should adjust the master cylinder rod out....or towards the rear of the car. I believe that is the right way....but someone can correct me if im wrong.

You can also adjust the resting point of the clutch.....but again you want to keep the pedals pretty much in line. But there may be room to move a little there.

Cheers

    • So next year I am looking at upgrading from my VE SS bomadore ute to something more refined.  I wanted to stick with a V8 but not anything German or Australian, either a coupe or a sedan. So if I wanted anything newish that limited my options to either the Lexus RCF which I quite like. But with the price they demand and a kid on the way a 2 door coupe is probably not going to be the best idea. The next best thing would be the ISF but the newest models are 2014 and commanding over 60k and even the older 2008 models in ok condition starting around 35k is kind of bullshit. So I figured if I could not have the noise I could perhaps make do with easy power. Enter the infinity Q50 or Skyline equivalent. The price difference between the 300 and 400hp models seems a bit crazy. Right now there is 300hp Q50 one on carsales from a dealer with 61km for 27k drive away. If I wanted to get a 400hp Red or 400R car the prices seem to start at 43k From my limited research it seems that the only differences are that the 400r/Red Red runs more boost and a more aggressive tune. There are are turbine speed sensors on the turbos. Has 2 pumps for the water to air intercooler. Runs an engine oil cooler. I'm guessing that the exterior trims might look a little more sporty as well. I had a lazy look for upgrades to bridge the gap on z1motorsports They have kits that upgrade the water to air heat exchanger as well as the coolant pump which should give a non Red/400r better intercooling temps than the stock Red/400r. I added an engine oil cooler with a thermostat as well to try and make things as close as possible. Obviously the ECU is going to need a tickle. Having not done much in the way of research they also sell a ECU flashing tool with pre loaded tunes that are supposed to boost the non Red/400R by 100hp which adds 1k USD to the cost. The total cost of the parts @ the current time including shipping and taxes worked out to be $4350 AUD. Personally I would rather get the car tuned on a dyno which would probably add more cost Assuming the worst that you got a workshop to install the new parts I would guess no more than 5 hours would be required in the worst case @ 5 x $150 per hour = $750 So the total cost could be around $5100 So for easy number 5k + 27K = 32k I guess that would leave some change left over to swap out the open diff and fit a LSD Any thoughts?      
    • Right, not sure why I thought it to be a lean spike. It might be fixable with modern card-style hot film MAFs which have some design features to avoid counting reversion flow but I've never tried it myself.
    • I did not realise this, I'll contribute more and earn my stripes and retry later. 
    • I'm only going to hassle you for posting links to images. It's against my policy to click links that could be some nasty payload. Sadly, you need to make 9 more posts before you can just stick the images directly in a post, unless @PranK sees this and bends the rule for you.
