how do i, test my clutch?

Is there a way to physically look at my clutch disc to see how much of it is left, without removeing the tranny, and how can i test to see if its slipping without a tach(my truc doesnt have a tach)??

To test for slippage, find a hill, go up the hill about 35 mph and put it in 5th, then floor it and LISTEN. How far from the top does the clutch engage?

it varies, as per my problem with the clutch doing the opposite of a hydrolic system leak. usually it engages alittle over half way to the top, maybe as far as 3 quarters of the way, but no more than that. thats how all of my sticks with hydrolic clutchs have been. i thought that that didnt matter anyways with a hydrolic clutch, i thought its suposed to grab in the same place regaurdless of how much clutch is there

Even a hydraulic clutch will probably start engaging right up at the top when it's worn out.

I'm old school - I hate hydraulic clutches. Give me the old adjustable rod linkage ANY day.

Well, you can open the inspection plate in the bellhousing and see if you can see anything.

You might be able to see something if you have a friend depress the clutch while you are looking - just a guess.

ok, its been awhile sense i checkd this last. we did that and i cant see house much clutch material is left. What i do know is driving home this mourning, i was going around a curve and i left it in 5th gear and when i was don with the curve i was going about 30 and instead of downshifting i desided to just accelerate up back to 55. so as i start to give it alot of gas to get back up to speed the truck i guess the best way to describe it is hoping or jumping? i felt it torque and even barked the back tired once. i didnt hear the engine rev up, but these were only for a plit second or so apiece and it happened from about 30 to 45 miles an hour. My buddy who i was giving a ride home said he thought it was the engine almost stalling. idk what it was. the plugs plug wires and such are factory original and the truck has about 120,000 miles on it now. when i stoped to come in for the nigth i put the truck in 5th gear and put the ebreak on and dumped the clutch, and the truck died almost instantly. also when i had the clutch looked at in march when i bought the truck the mechanic said there was between 40 and 60 percent of the clutch material left. i was gonna pay to have a new cluthc put in so the droped the tranny and such. he told me that and i told them to just leave it. (they didnt charge me for droping the tranny so..) so is there a possiblity that the clutch is going? or is it likly an engine problem?(if so i will post in the engine section) also this is what happens when i drive up a steep hill in 5th at 30 miles an hour or so and i floor it.

You are overdue for new plugs. Start there and be prepared to change the wires and coil packs.

Sounds like your clutch has plenty of life left - as long as the master and slave cylinders don't start leaking the factory clutch is usually good to at least 150k unless you abuse it.

That tells me the clutch is NOT slipping. Flooring it at 30 in 5th, it should simply slowly pick up speed smoothly, if it misses and farts you need a tuneup. Again, 120k on factory plugs is past service life.

Measuring clutch wear is easy. Buy a new clutch, use a micrometer to measure it. The use a micrometer to measure the old one. Subtract the old one's measurements from the new ones measurements and that is how much you have worn off.

Maybe you don't mind pulling a trans just to measure the clutch but if I go through that much trouble it's getting a new clutch.

Exactly - that's why when my slave blew I put a whole clutch kit in.
