3600 DD is slipping I just put in this spring I have 20k on it and can not give it over half throttel, it is like you just throw it in Nuetral it slips so bad. I think something may have broke in the clutch?? I will have to call tomarro and see what I can do with it?

 

Yep something isnt right... Give peter a call...

 

3600 DD should be a lever-style clutch (not diaphragm), so Peter might ask why it's on a street truck, since it's more of sled clutch.

Did you get the hydro upgrade?
Also, one of the 4 levers may have broken.

 

Why wouldn't it be on a street truck? I am sure almost all of them are on street trucks, including mine. That is why I got a DD 3600 was for its all around use.

 

Mine is a 4 lever style as well.. purchased just for the all aroundness of the clutch... and definitely not a sled pulling only clutch... In fact mainly the opposite

 

That's what I thought too...and that's why I bought the 3850 sprung hub. However, after one of the fingers on mine broke, I called Peter, and he talked some sense into me. He said that the extreme plate loading that I had could be driven daily, but would fail prematurely by being cycled in and out frequently. The 3250 is the clutch meant for street driving. The heavier plate loads can be driven on the street (and I did for a year and a half), but their finger design pressure plate is not meant for this; the 3250 is a diaphragm design, and works very well.

You're a good stick man, Brian, so the DD ought to live for a while... don't lose any sleep over it!
The 3600 may well be a 'tweener clutch that works fine over the long haus.

I know Peter recommends the 3250 as best for daily drivers.

Makes sense from an engineering point of view, as lever-operated pressure plates can exert more clamp load, but are more likely to break. Diaphragm-style plates are smoother (and easier on the throwout bearing, IMO) and will usually bend (over center) instead of break, but typically don't reach high clamp loading in comparison.

 

peter told me to pull out the slave cylinder and check the lever it should be loose. I did that and it was tight aginst the front of the tranny. Now he wants me to pull tranny and take pictures of the clutch and e-mail them to him I will not get to do that till monday morning before I leave for the sema show..

 

First time I've read about the fingers breaking. This isn't very common is it?

So now if a clutch is going to be in a daily driver the diaphragm style plates are what is recommended? I was under the impression you could daily drive whatever you could stand? In making a few calls earlier today a vendor was telling me I could maybe get a diaphragm style plate with a higher load than the 3250 or 3400 or whatever it happens to be?
Sorry if this is a slight hi-jack I should probably start my own thread for my questions.

Justin just out of curiousity how have you treated that clutch? What has it been through? Thanks

The 3600 lever style is the highest plate load for street use, the 3850 is where u will have problems as daily driver because of the plate load the levers will become weak over time and break so thats why Peter recommends the 3600 DD if the truck is gonna be a DD and be pulling on the weekends!
I have somewhere around 3k miles on my 3600 so far and havent had one
issue. The clutch is a breeze to drive!

 

Well I got a new clutch and compaird to clutch I had and when I set the two fly wheels side by side the new one was not as tall as the one I had. That was a good sign to me. So I installed the clutch and the shift fork was not tight to the trany bellhousing, there was like a quater of an inch of play in it. so that was a good thing to see. on the test drive the clutch grabs about mid stroke on the pedel. Were the other one grabed twards the top of the stroke when new. also good to see. then for some reason the clutch is not as loud as the one I had before, not that the noise botherd me just somthing I noticed. Over all this new one I got is quite abit better that other clutch. I just have to send the old one back and then mabe peter will notice the flywheel differences, then I will see what will happen to the warranty.

 

You put the same type of 3600 back in? Or did you go with something else?

 

The same one.

 

How many hooks did you have on the old clutch?
