More about a T19 swap

[Diesel JD]

RE: the master and slave cylinder...the Haynes manual keeps saying that the pre 87(T19) uses a complete M&S setup that is not available separately. I have heard of you guys replacing just one or the other. I haven't even ever seen a prebled M&S assy. for a T19. The one riotwarrior was talking about turns out to be for a 92-96 ZF5. I still don't know what I want to do, but I know I want to put that T19 in there here in the next few weeks. Just trying to gather all my parts so its a long weekend and not all Christmas Break. Is there a pre assembled setup for the T19 or is Haynes wrong again?

Both Napa and A'zone list seperate parts for '87. I'm beginning to wonder if Mr. Haynes is a 'recruiter' for Mr. Murphy

 

[Diesel JD]

Yeah...how about the idea of preassembling and bench bleeding the master and slave? Can it be done...especially when you are adding them to a truck set up fr an auto? Thanks

Yeah I just bought the master cylinder seperate from the rest of the system. It was dry of course (no brake fluid) so what I did was kind of fill up the master cylinder out of the truck and pushed in and out with the push rod thing until a good stream of brake fluid was coming out when I pushed it in (it required a few fill ups). I then carefully put it into position trying not to throw it into any real angles so that brake fluid wouldnt come dripping out (cause I hear that brake fluid causes paint to peel, thats on thing I dont want to experiment with). I then re-attached the line that goes into it. I went under the truck and loosend the bleeder allen screw on top of the Slave cylinder until a good stream of brake fluid was coming out (make sure you have a lot of rags, its a messy job, or you could put something under the stream to collect the brake fluid like I did). I thought this would get out all the air pockets, but it didnt. What I ended up doing was like somebody said to do if you were going to do this alone. I climbed under the truck and pushed the slave cylinder inwards, towards the back of the truck. Dont do it to hard or brake fluid will come gushing out of the master cylinder, because you have it open to be able to fill it with brake fluid. I then held the slave cylinder arm in for a minute or two, until I couldnt see any bubbles go through that red hydrolic line. Then comes the tricky part, with the slave pushed in (which is kinda akward to do, and you have to put out a fairly good amount of effort to keep it in) you take your free hand and tighten up that allen screw. A word of advice, figure out which way to turn your allen wrench thing to tighten it before hand, cause you might get screwed up and go the wrong way, and that really sucks because its a PITA to hold that slave cylinder in. Once you get it tightened up go back in the cab and hook up that little push rod arm thing to your pedal linkage, and test it to make sure it works.

LMC truck parts page listed....Now I am not 100% certain but if the ZF uses an internal hydraulic throw out bearing, as I believe they do then you could not have a complete pre bled system for one. I have a ZF line and it screws into the side of the the transmission, and there is a small bleed screw next to that.

My T19 setup looks just like the diagram on the LMC page, I feel that if one was to Bench bleed a complete system it would sure be a whole lot simpler than while on the truck.

I have a pre 87 MS and in my 90 and it's **** eyed like all get out. I have to switch to my replacement 90 MS and I just happen to have a second line and slave that I know works so I was going to Bench it and attempt to bleed it that way when I put them together....there is no reason I can think of that it would not work.

All interesting stuff. That's one of a couple things I'm concerned about. Nobody seems to be sure if the speedo and odometer will work with the T19...anybody? The other thing is the trans. x-member and driveshaft. I'm not sure, it seems they are different sometimes and not others. Any input,
JD

That is only for the small block zf. The diesel/Big block zf Is basically the same as the t19. In fact you can use all the t19 stuff on a zf.......Slave and master.

How hard is the pedal assy. to get out of the donor truck? I'm a little scared of wrenching under junkyard trucks. I don't want to get killed under it.

 

[riotwarrior]

Pedal assembly is all done from within the cab and under the hood. I work 3 days a week at a wrecker and actually just finished stripping down a F150 yeesh...POS. That aside the pedal assembly is easiest to remove if you pull the steering column first....then you can work easier under the dash to remove the parts needed. Make sure you keep all the bolts,nuts,clips,pivot bushings etc.

In my opinion it's a simple procedure but then I do this for a living.

As for shafts, what truck? Wheel base, cab configuration? Crew? Super? Reg?

Is this a 2x or 4x? More info on the truck allows people here to give better answers.

If your getting the trans from the wrecker, why not get the speedo cable too, that way, your assured of a correct fit.

At the most you might need to change the driven gear on the speedometer cable.

So what is involved in changing the slave cyl on a ZF-5 on a gasser? What can I expect to pay for each?

 

[Diesel JD]

Shafts....well the truck is a 2WD extended cab...probably long wheel base...not really sure. I already have the t19 in the garage, just waiting on the bell and need to grab the pedal assy and a few misc. parts. I know its suggested to pull the steering column, but I don't want or need it...don't have any wheel pullers...it'd be better if I didn't have to pull it even if it made the job a little tougher. So you say that you can reach everything you need from under the dash or just under the hood on the pedals? Thanks,
JD

From what I remember yes you can, I know you can change out pedal assemblies on 92+ with the column in place.

OK as for shafts, I'll check at work next week while I am there...

If you want to pull the pedal assembly, you will have to take and undo the steering column from it anyway, as it bolts up to it. The simplest method is to undo the bolt on the RAG joint on the steering box that holds the RAG joint to the box, undo the large black panel the column passes through the fire wall, I think there is about 4-6 maybe 3/8"headed bolts, then undo the big grey wire connection that comes down the column and then unbolt the column from the pedal assembly.... then you can pull the column out towards the interior and you can have clear access to the pedal assembly

Place the column out of your way...you wont need to pull the wheel or anything just get it out of the way is the goal....

I'll be removing a pedal assembly in the next week or perhaps this weekend not sure...I'll photo document it as best as I can...Be advised the column is already out and the dash is ripped apart...so it's basically going to be picking up from where I have instructed thus far.

If you leave the column in you'll only make it way way more difficult to work on...I mean really it is that big a difference to remove the column first...


Now Dieselguy123 may be correct on the 92+ trucks I am not certain, I am working on a 90 and have worked on mid 80's as well and both of those body styles make it much much easier to remove the column first...

I do this stuff for a living and the time it takes to pull a column first to me is well worth the effort as I can pull the pedal assembly quicker and simpler...

This is just my opinion and 2cents worth so take it or leave it your choice....

 

[Diesel JD]

OK, guess I will be pulling the column...maybe they won't make me buy it...or maybe it'd be good to have a spare manual column? I was under the impression that you needed to pull the steering wheel. So once its unbolted from the rag joint and the electronics are disconnected it'll just pull out on 80-86 and 87-91? And does it matter if its an 87-91 or a 80-86 for the pedal assy? Thanks
