hyd clutch pedal assembly from late model chevy truck?

[chevybill]

Have any of you installed a late model hydraulic clutch pedal assembly in any of your trucks. I have a nv 3500 for my 70 and I am going to a junkyard next week to try to find a pedal set to use or graft the hyd clutch part over to my original pedal assembly.

Does anyone know if a tri 5 (55,56,57) chevy pedal assembly will fit in our trucks or perhaps an impala (thinking about the fact that impala wheels are 5 on 5 like a truck wheel pattern).

thanks for your replies

I am using a hydraulic clutch and hydroboost system from a 1989 1 ton (old body style) on my 69 K20. I looked at swapping the pedal assembly but that would have taken a lot of custom work and was very simple to just mount the pushrod to the existing pedal assembly. Here is a link to info on my install.

thanks for the reply, when you say later model in your link what years are you referring to?

thanks for the link as well

A 1989 can be a new body style or the old body style. The old body style is the one I had the master needs the shim. The new body style 89-up doesn't need that shim.

thanks for your information, i guess not many guys have done this.

Yukon thanks for the link should work for a 2wd also correct with the exception of the hydroboost..

Board member Huck from KY was the first in this board to do this kind of swap, he did this a few years back and has since sold the truck I believe, I personally saw that truck when I first met him (sweet truck) and it was hard to see or know that the ol' truck he was driving had in fact a 5 speed tranny in there as he hid the hyd. clutch under the brake booster )I wouldn't had known if he hadn't said anything) you may want to send him a pm and ask about the particular setup he had in the truck back then.

BTW: Huck's truck was a 2wd if it matters any

thanks,chevy fatman, just been little response so far. thanks for your resposne, my truck is a 2wd, by the way.

[Yukon Jack]

Both the hydraulic clutch and hydroboost will work on a 2wd - the donor truck was a 2wd.

I need to get some pics of the bellhousing added to my link so people can see it also.

I put an aftermarket Tilton Hydraulic clutch in mine. Looking good so far with the Richmond 6 speed....Truck is not done yet so I havnt tested it out. Very nice components though.....I had a 88 Chev, truck that had a hydraulic clutch that I could have modified something similar, But I wanted to run the Hydraulic Bearing not the Slave this time......It eliminates the pivot and arm as well. Looks real clean!!

[chevybill]

kcw, could you post a link or some more info, could this work with the nv3500?

I used a hydralic throw out bearing makes it alot easier to hid any resivor you use Ill try to get the name posted of what the throwout bearing is

I'm about to install a NV4500/Twin stick np205 in my 67 and was going to use a hydrolic setup.This perticular one is a 99'+ bellhousing with the left side setup.Will an older Hydraboost work with my setup? Is it fairly simple to setup?

[Huck]

I installed a 5 speed with hyd clutch setup out of a 96 1/2 ton chev truck. I installed the clutch master cylinder on the firewall behind the power booster--just more center to the body on the inside of the brake assembly. I used the stock original brake/clutch assembly and fabed a bracket to attach the clutch push rod to. This unit has the internal hyd throwout bearing. The unit worked well but needed a bit more pedal pressure then I would have liked. Also the aluminum transmission was designed for an electronic sensed speedo which I never addressed. All in all, it is a nice swap especially the OD 5th gear. In my experience, if a mechanical clutch will work, I would prefer avoiding hydraulics as they tend to be less forgiving---ie. leaks, bleeding, adjusting issues, etc. In one case, my clutch master cylinder let loose from the firewall and I had to drive the truck 40 miles shifting without the clutch--via rpms.

huck, what you done is basically what i am doing, except i do not have the luxry of a complete donor vehicle. i am piecing together stuff as i can and

i appreciate your response and information.
my particular nv3500 has a integral bellhousing, so that complicates things a little.
so based on your response you used your old original clutch/brake pedal assembly and adapted the hyd clutch to it. is that correct?
