My 94 4x4 PU is having clutch issues. The clutch was done a year ago by a reputable shop locally (I had no choice at the time.)
I have Rock Crawler wheels, Super Swamper TSL 32 x 10.50's, stock 4.10 gears. I have to really rev the truck up (far more than normal) in order to get the clutch to engage. If I don't it staggers and will stall. I also have to ride the clutch quite a bit before I am fully engaged and can go. This happens especially if I stop on an incline and then go from there. It is not a ceramic clutch. It is an OEM standard clutch.
Any help or advice would be great.
Thank you.

i don't understand, revving the motor up makes the clutch grab?

are you saying that it just engages harder/quicker?

toyospearo

In essence what I am saying is I have to rev up high and ride the clutch for a few seconds in order for the truck to go. It is anything but a smooth crisp take off. It stagger and stalls if I dont ride it.

TOYOTA 1

ok so your saying it engages all at once, gotcha.

hmmm, does the pedal feel the same as it did when it worked fine?

Could the pressure plate be contaminated with oil? I had a rear main go on my F250, it caused similar problems to what you are describing... Good luck!

I had the clutch kit installed, flywheel resurfaced and the rear main seal replaced. I suspect the size of the tires and wheels have something to do with it but I dont know. Pedal seems the same I just have to ride the hell out of it now.

Throw on some smaller tires and see if it helps.

Either the clutch is worn out, ther is fluid on the clutch, or the pressure plate has become warped. If you have to rev high to get it going, if it's not worn out, it will be soon. Chances are the chatter or "clutch stutter" as I call it is from a warped or uneven pressure plate surface.
Your tires should not anything to do with it. I've had stock clutches do just fine with 35's. I also warped a pressure plate in a deep water hole after a hard hill climb (hot, then sudden cold water soak).

now that i think about it mines that way to. but its old.

it takes some getting use to,

i just deal with it... my buddy said somthing about those springs in the center of the clutch going bad might have something to do with it??. at least its not slipping

abecedarian

so the clutch grabs too soon and stalls the truck if you don't slip it?
first I'd recommend a good bleed and adjust.
then if you have to ride the clutch to get it going, with a hairline between fine and stall, then I'd suspect your gear ratio / tire size

unfortunately, we're missing a full description of what's going on.

TOYOTA 1

x2.. except for tire size, hes only got 32" tires. ive ran 33" swampers and 4:10's i never had a problem.

Maybe the clutch disk was installed backwards?? Not sure what problem that would cause but just a guess.

abecedarian

Who are you and what are you doing suggesting such things?

and why weren't you here sooner?

toyospearo

Actually, thats about right, that is what is going on.
Gears are stock and the tires are 32 x 10.50's SS TSL's.
I suspect swaping the gears with 4.88's would solve this problem (should it be the gear ratio / tire size.
I am unclear as to what more description I can give without tearing the thing apart and posting pictures.
I might add, if I am stopped on a hill and go forward I REALLY have to ride the clutch and the hairline becomes thinner between fine and stall.
I and a lot of folks around here would be very skeptical about this shop doing shoddy or shady work. They have a very good reputation for tranny and clutch work in this area. So I don't think I got screwed.

Okay, did you have that tire size on with the original clutch? How did it feel then??? ETC. Was it completely fine until you got this new clutch in?

toyospearo

Forgive me, I had to go look at my receipts to jog my memory.
No, I had stock wheels and BFG's all terrain 30's when I put the new clutch in. I drove the truck for 3 to 4 months after this with no (if I remember correctly) problems. Then I bought the RC wheels, SS 32x10.50's and it seemed as if things were fine and then got progressively worse.

TOYOTA 1

well the question is why did it get progressively worse? i mean the tires didn't get any bigger

toyospearo

Is that sarcasm or..??
The tires where 30's and then 32's The question is why did it get progressively worse?

904_runner

Therefore it sounds maybe its tire related.

Is it possible that when you switched to bigger tires, you started messing the clutch up? Maybe over heating or warping the clutch, etc...???

toyospearo

I suppose so.
That is what I am trying to figure out. I wasn't aware it was possible to mess up the clutch by switching tires especially in less than a year. I offroad, hunting and exploring but nothing all that serious.
I am really careful with this truck.
