Soon as I get a few things squared away on my K20 I will be working on my m1008 again. This summer I plan to put in a hydro 465/205, get it tagged, insured and registered, and swap a k5 tank or fuel cell into the bed (saddle tank has leaked out all over the backyard). Maybe also do just a little driving in it to fix the little things that break once you drive it awhile.

Anyway, my question is, what clutch should I go with, its gonna be almost offroad only (90% offroad). May do a few short drives here or there just to drive it some, run to autozone or napa something like that. (nothing more than 20miles).

I dont want something that will have a heavy pedal, even though I am going with a hydro clutch, as I plan to let the gf learn to drive a stick on this truck (figure she cant break anything, and if she does oh well), and she'll probably want to drive it offroad and I dont want her leg to get tired after 5mins, so a relatively light pedal is a concern.

I dont forsee needing super power holding capabilities as after all it is a 6.2 and not a 5.9, but I dont wanna burn the thing up either.

One last question, a quick search on summit only turned up pilot bearings for the 6.2's. Ive only ever had experience with bushings, is there a reason the 6.2 doesnt have a bushing, but a bearing instead?
 
Not sure on the why in regards to the pilot bearing, but that's what it called for so that's what I installed on mine. I run the Hay's Super truck clutch. 12 1/8" disc, diaphram clutch. I like it...and with a hydro pedal it's not too heavy. OTOH it's not a girly Honda clutch either.

Yeh thats weird cause Ive always hear the bushings last longer b/c they are maintenance free whereas the bearing has moving parts it should theoretically need grease, but because you cant, it will eventually wear out.

As for the clutch, how stiff is it compared to say a remanufactured autozone clutch for a 350? I know thats what my buddy has and I can almost push it down with my pinky.
 
Well, I did grease the bearing when I installed it..not packed full but a good coating. The surface speed that bearing sees is pretty negligible, and only occurs at idle really.

The Hay's I have is advertised as a "puller" clutch, so it's not something you could depress with your pinky. It's not horrible, but it is a 'man's clutch' for sure. I think most of this is stronger springs in the pressure plate to increase clamp force. That combined with the larger than stock disc diameter it'd be pretty hard to get it to slip. This does make pedal effort more noticeable though. It's a lot lighter than my old Borg & Beck clutch with manual clutch linkage...that thing was brutish and so heavy it was almost impossible to feather. Also lighter than a reman diaphram clutch with manual linkage.

Why don't you come on over and try it out? :p:

I wish i could put a number to it, but in the end it's kinda subjective...and relative to what you're used to.

If you're used to a Honda it's Heavy. If you're used to manual linkage and a three finger clutch it's light as a feather. :doah:

Well Im used to the one in my dads 7.3 powerjoke, its fine for me, if you get stuck in stop & go for 2.5hrs itll make you wanna cry but other than that it aint bad. Hes also got a 4cyl s-10 that is pinky pushable, but my 15EEEE boots dont fit in the floor too well so I can count on one hand the number of times Ive driven it lol.

I`m driving a 4cyl s10, and although I`ve never driven another standard, I`ve felt the clutch on my buddys dads 6cyl s10, and his definitely felt lighter...
 
Im dredging this one up from the dead, but I was bored, out of money, etc and was looking into the bearing/bushing thing. And found that the 6.2 uses the same ones as a 92-97 lt1 350 or a 97-00 454. They both use the same bearing, so it stands to reason a bushing would work in the diesel, now Im off to find info about the diesel to see if there is a reason for the bearing, maybe some kind of vibration dampening.......
 
I have a bushing in both my standard 6.2L trucks, specifically put one in rather than the bearing as they seem to fail fairly frequently.

The NV4500 amplifies the engine rattling significantly when you are at idle without your foot on the clutch, but that may work out that way regardless of what type of pilot bushing / bearing you have.

The NV4500 has a Napa Severe Duty clutch and a stock multi-finger pressure plate. The hydraulic pedal is significantly firmer than the one in my 96 daily driver, but is still less effort than the mechanical clutch in my old 74 was.
 
ok so you run a bushing in place of the bearing that all the clutch kits come with, sweet, kevlar bushing, and Ill never have to worry about it again.
 
Yep, the 6.2L uses the same bushing as a gas 350 does, so anything that'll fit a 350 will fit your 6.2L
 
Good to know...because with the NV4500 a pilot failure quickly leads to input gear fragging, and my 6.2 is out right now so it's easy to get to it. ;)
