3rd gen clutch life expectancy

Well, I doubt you have to worry about the accumulator causing premature wear. There is plenty of anecdotal evidence that these clutches will last a long time with a completely stock truck.

What I CAN tell you for sure is the immediate effect on driveability when it is removed/modded - the vagueness of engagement goes away. The clutch responds exactly to your left foot input!

 

It definitely allows a bit more slip on engagement. Yeah, it is not going to wear out a clutch on its own but doing the ADM will add some miles to the life.

 

I believe the accumulator will actually increase life of the clutch.

 

I have the part to do this... I really need to get around to making the time to do this...

 

To each their own. I enjoy driving my M/T more with the damn thing modded.

 

You absolutely do lol.

 

Is it something I can do by myself, or will I need assistance with bleeding the line after I finish it?

 

I just ordered a kit from Trident. Cant wait to remove that pos! Any tips?

I got 17k km on my clutch.

 

I had a helper both times (my '16 and now my '19). I don't see it being something you could easily bleed yourself without special tools.

 

Yes - have you visited the ADM thread? If not do that first!

 

I do not see it that way given how it functions. I am curious why you think that?

Sort of. If you do the gravity bleed method, folks have done it by themselves. I had a helper for the bleed portion only. 10min max of help on my end.

 

I have no doubt it's a better feeling of engagement. I should have elaborated a little more. I believe that Toyota believes/believed that the accumulator will add life to the clutch. Now it could be doing the opposite. Adding a delay to the engagement while the operator is already accounting for the "lack of engagement feeling" compounds the issue.

 

I did the gravity bleed first, then a "proper" bleed with a helper. There was quite a bit of air in the system to get rid of.

 

Very true.

I believe Toyota added this to help newbs get engagement down. While that might help with shocks through the driveline, I can only see that it allows more slip, all things being equal.

The fact is that a newb should have 95% of the clutching down in a week or less. From there, more feel and direct action would benefit a newb.

My wife picked it up in a dealer parking lot. Of course, she was buying a 70hp Geo at the time.

 

Interesting. I know mine continued to flow slowly during the 90min that I was kludging things together. One helper pump was all that I really needed when done but did two more for insurance.

 

Yes, ive been reading a lot about the ADM, just dont wanna fuck up getting air in the system haha.

 

If those folks have to replace the brakes and rotors at 49K, that goes a long way in explaining how the truck was driven/treated, and hence the needed repair issues.

 

I suppose it could help prevent clutch damage and driveline shock from errant/noob dumping. For me, it was absolutely something I had to compensate for. Forces you to sloooooooow down to be buttery smooth.

 

I think that is the exact reason behind Toyotas design of the accumulator and in theory should add to the life of the clutch.

 

Well, as Tonered alluded to - after everything was re-assembled I opened the bleed valve a bit on the slave cylinder and then took the clamp off the supply hose. I already had the bleed hose/bottle hooked up. I then allowed fluid to fill the system until it began dribbling out of the bleed valve. I could see air coming out while doing that.
Next, I closed the bleed valve, topped up the reservoir, and had my helper pump the clutch a few times.. then push it in about 1/4 way and hold. I told him, when I say go - slowly push the pedal in. I opened the bleed valve when I said "go" and closed it before he got the pedal to the firewall. The last thing you want is air being sucked back in through the bleed valve. Anyway the clutch pedal may not return on it's own during this process, but not to worry - you can have your helper pull it up by hand. After each round of bleeding I had him pump the pedal a few times. After about 4-5 cycles, there was no more air coming out and we were good to go! All I did then was top up the reservoir again and re-install the heat shield.
