'22 Clutch Pedal Adjustment

Hey All. Picked up a '22 TRD OR DCSB MT in the past 2 weeks and the clutch pedal just doesn't feel right to me. It could be that this is my first MT truck so it just feels clunky. It has about an 1"-2" of play at the top before I feel any tension. I put some Husky Weatherbeater floor liners in and when I engage the clutch I have to push it into the floor mat. When I go to start the car I have to push pretty hard to get it to turn over. Just wondering if there is any adjustment to lift it off the floor like 2cm or so.

Looking for any advice! Thanks!

 

@ShirtTucker This is extremely helpful. Thank you so much.

 

FYI there is a different part number (#13961) for the front mats with a manual transmission specifically for the clutch pedal

 

Same deal here...With those hard Husky floor liners, i really have to push through the mat when starting, or else the truck wont turn over. For normal shifting, I don't have to push as hard...(*insert Michael Scott joke)...otherwise it engages well before coming in contact with the liner. I don't know if it's the hard non-oem liners, or what...

 

Thanks, yeah I double checked and I have the correct part number for my year, which is 13981.

Ha, okay. At least I know it's not just me!

 

It seems as though the switch/sensor that needs to be triggered for the ignition wont engage unless the clutch pedal is FULLY depressed...for gear rowing, it's not near as far...
...in my case at least.

 

Same, mine drives fine. I just need to put my foot through the engine to start it.

 

exactly - lol!

...hoping those huskies will break in just a little...they are stiff!

 

They're not for the clutch pedal, but the shape of the dead pedal is different, at least for the factory mats.

 

There is a switch on the far end of the pedal travel that I believe can be adjusted. The pedal area is crazy tight to get in there.

 

Can confirm its crazy tight down there. I installed a gas pedal offset spacer and was a bear.

 

Close up the gap between the pedal and push rod. Leave the tiniest gap you can but be sure there's a gap. Leaving no gap is asking for premature throw out bearing wear. Also, the plastic top-hat that pivots between the pedal and pushrod could use some plastic-safe lubrication. Use what you prefer.

For the love of all that's holy, get rid of the clutch accumulator. I waited till the 36k was up and I wish I did it on day one. There are a million ways to do it, I used a flex hose and banjo bolts.

Now it feels like it should. Predictable clutch engagement, pedal feel doesn't change until <30*F and at that it's like any other of the dozen manuals I've had.

edit: hey, i just looked at the FSM Shirttucker posted and it says 1mm gap. Go me

edit #2: The extra-weird dead space you're feeling is the combination of the big spring that holds the pedal up and the actual pressure place resistance. [edit]. If you notice that your clutch grabs strangely close to the floor, that's why. The effect of the spring fades after about half of the pedal travel then you're actually pushing the pressure plate out. (Figured that out when bleeding the system.)

So it works like this: you start pushing the pedal, [edit], the spring makes it feel like you're actually pushing a normal clutch. The spring effect fades right about where the pressure plate is actually providing resistance and that's the strange, two-step feel you get.

The three things you feel are air-gap to rod, pseudo-resistance from the spring, [edit], then the actual pressure plate's resistance.

I tightened up the air gap and removed the accumulator. The clutch engages in the middle of the throw, I don't feel a pressure change in the throw and the pedal doesn't nearly stick on the floor when below freezing. Now, I DID have to relearn my habit of stabbing the pedal to the floor since this truck is like many others and it's not needed. I have other vehicles (fun cars) that engage right off the floor so there're always a few bad shifts when going between toys. Ah well, first world problems and all that.

Edit #3: Tonered made me reanalyze things I thought I'd figured out, it's been so long that now I'm not as sure, so I redacted a few parts so as to not mislead.

 

I wish we had a linear spring, or a linear spring mod.


Sorry though, but the accumulator does not get pressurized. When off the pedal or disengaging the clutch, the accumulator is at rest. Only when the negative pressure is applied by the fluid on engagement does the disk move inward to restrict flow. The square seal in there does double duty as the actual moving part.

 

OP: trust this guy, he's been way deeper than me. I can see what he's saying. I stand corrected.

Here's Tonered's glorious thread on all that.

Yeah, I just started reading through that. I may consider attempting to do that. Judging by the comments, it looks like I will get the feel and response that I am looking for.

 

Every vehicle has its quirks but this will make it feel like what you would expect any generic (read: old school) clutch to be.

Important: this is NOT specific to Tacomas, Toyota, etc. No one is at fault, nothing's actually wrong, all manufacturers do it these days. We as end users just have our individual preferences.

 

The discussion is always good. You are right that accumulators typically charge, then deliver that energy at a slower rate. Ours is some screwed up science project that just messes with folks. Haha!

 

FYI: I had the same reaction when I started driving my 22. the weird play at the beginning of pedal press and the overall clutch being super soft. It gets better over time. Give it ~1000 miles, it'll feel much better.

And yes, full press to start truck but to shift gears you can do almost 1/3 of the range of motion. Makes for much much smoother shifting if you get the hang of it. Full press gets clunky. Can almost heel toe the clutch. Takes some getting used to.

I added the sprint booster and had to relearn the clutch timing.

 

If you are interested there is a guy on here who make gas pedal spacers that make the gas pedal closer to the brake and at the same level as the brake pedal. I have one and really like it.
