Has anybody made a hybrid clutch hose to use an internal slave cylinder with the factory master cylinder?

NV4500 hose question
- Thread starter oldtoyboyd
- Start date
i had most of the stuff to do it but never got there. never found a good used hose. and you needed to get the whole master from the dealer to get the hose at that time. so i got ride of the stuff and went th400 instead.
sorry but i cant help. but i would like to know incase at some point i can do it.

Do you know definitively that they are of a matching displacement? I've heard plenty of rumours like this, but nothing concrete.
If the displacement is the same, I'd be really happy to go back to a 85 - 91 master cylinder from a square body truck with an SM465. My clutch pedal is really heavy with the 94 master cylinder due to less than idea geometry on the clutch pedal pushrod...

Why would you even consider wanting an internal slave cylinder? Just think what a pain it would be to change if/when it goes bad. It's doubtful you would be changing this on a trail anywhere.

86-91 use 17.75mm bore and nbs use 18mm bore
If I go this route I don't have to buy the adapter bellhousing and all to run it behind my 454.
I am putting the cummins in next summer hopefully and all ready have the bellhousing for the cummins.
Really don't feel like buying the other bellhousing setup to use it one year and loose my tail but I want the overdrive now.

Cool... I'm gonna find a 85-91 master cylinder and give her a shot then. I have an idea of how to splice the hose too

I did make a hybrid hose for going the other way. It seemed to work but I didn't trust it. I cut the plastic section down and heated the end up and pressed it back over the metal fitting.
In the end, stainless braided brakeline with the right fittings was easier to make work.

The stock clutch master isn't going to work with the Cummins, the bore isn't big enough.I tryed to make this work for the longest time and gave up.
Here is my hyd kit that I made,the master will push the 13" clutch and the master block puts the rod at the same angle as the stock master. The line will work with the dodge slave.

Not really the same but I made my own hydro line once. It was on my 96 C-1500 with a NV3500. The plastic line split and I lost all the fluid. So I figured I would just get a new line. Wrong! Had to buy the whole master cylinder to get the line. Well seeing as I was 2 days into a new job and broker than crap I had to think. So I went down and got some brake line for like $7. Then I got my little tubing bender and bent it all to the same shape as the factory line. So then I had to figure out how to attach one end to the master cylinder and the other to the steel braided line the stuck out the side of the bell housing. Well it took me about an hour to come up with a redneck brain fart, but a brain fart none the less. I figured if it didn't work I was only out $7, but that was better than dropping $100 I didn't have.
Ok so what I did was pull the metal fitting out of the plastic master cylinder that the plastic line was attached to. It was only held in with drift pin. Then I flared the end of the new metal line and slid/forced it over the nipple of the fitting. Ok so next step was how to keep it on. Simple I brazed that prick like a plumber sweating copper. Then I did the same thing on the other end with the nipple coming off of the steel braided line (kept the rest of the line in a bucket of water). It worked and worked good. It was still there when I traded the truck in 5 years later. Hell I would do it again, it worked better than that plastic POS line that forced me to get towed 95 miles from home.

I plan on using you hydraulic setup when I do the cummins. I am trying to install the trans ahead of time and use it with the stock master for now.

Back from the dead
I am also in the same boat.
I have a 96+ NV4500 and need the hydraulics. I can see LMC has the setup minus the hose.

Also they require a couple 4 dollar nuts? WOAH?
I'm not sure if I should try to purchase this stuff from a dealer or try to Frankenstein things together! Dealer has a master that includes the hose is what I'm hearing.

Keep in mind that the dealer/lmc hose is for a drivers side master and a passenger side internal slave. The length of that hose is too long for a drivers side external slave and it'll be really hard to bleed if you have any loops in it.
Factory NV4500 internal slave exits on the driver's side IIRC. Only the external slave is on the passenger side

Yea, that's right. I was confusing the external slave I had since it kinda went through the bellhousing.

Cool. Thanks for help. My options I believe are to get the master cylinder from the dealer as it comes with the hose for around 120. Then buy the slave from autoparts store for around 80 bucks. Should be good to move on from there!
Then its putting everything in and making that clutch pedal work!
