I used a mech. setup with my NV4500 in the '82, works great but I don't really 'wheel with it. I like it 'cause any issues will be a 10 minute side of the road fix, where a hydro setup is a pain in the butt if anything goes wrong.
Biggest argument for hydro setup is that you don't have to worry about linkage binding when your frame flexes, difference in clutch pedal stiffness is insignificant.
you could go either way mec is much simpler but has the habit of binding when you get into a good flex and hydro is much more work but it does not bind becase only a hose is connected to the body it all depends on what you do i have used both i like hydro hands down over mec
I almost agree with toomany. I think most of the supposed stiffness in the mech setup is from the style of clutch not so much the operation of the system. I have mech because that is what my truck came with; after replacing the borg warner clutch with a diaphragm style the operation has become a lot smoother and easier. I have heard that flexing your truck can cause mech to bind up which has never happend to me. Also I have never torqued so bad the pushrod came out. That sounds like bad mounts or a busted t-case adapter letting the whole driveline move. All that being said I voted for hydro simply because the operation is simpler and far more modern. With a little innovation people have converted the mech bellhousings to work with hydro setups with success. Once it is dialed in you shouldnt ever need to mess with it short of ensuring that the master cylinder is serviced and not leaking.
I guess I should add that before I rebuilt the mech. setup, I had problems with the engagement point changing and the linkage falling appart in certain situations. Since I've put new parts in and welded/drilled the holes round again...it works awesome.
Rocked the caveman clutch for about 10 years, learned that diaphram clutch is much easier to use. Went hydro when I swapped my NV4500 in. It does feel a little lighter, but not much.
now I have the hydro set-up with my NV4500 doubler combo still, plus the 87 Crew Cab I picked up has a hydro clutch too. I'm pretty sure that beast has the three finger Borg & Beck though...it's a lot heavier and doesn't feather worth a sh!t.
hydro. easy to set up. easy to push in. I dont care what you say about being a pansy. I drive 18 wheelers becuase i work on them. You get tired of pushing one in really hard. mine I can push mine in with my hand and if you wheel for hours on end your leg isnt tired.
i have hydro, i changed all the parts(parts store went out of buisness and i got all the parts , center force clutch all for a super deal)...since then,3 years ago its worked flawless through everything..
When I swapped the BBC into my 69 K20, I put in the donor vehicle's hydraulic clutch setup - really like it, other than it was difficult to get bleed initially.
