What Did You Do To Your Jeep Today?

It seem to me with a z-bar linkage and multiple levers and links, a manual clutch linkage would have more places to impact free pedal, and the ability to disengage. In this application you would only get a minor amout of lift from torque twist. no front to back movement.

 

I agree, and now I think I see why you are asking. Your throwout arm is pretty long, and lines up better with the frame. I would be concerned with finding a master-slave combo that can travel that far.

 

It's a stock Bronco arm and the max movement is under 2". The matched set of cylinders that I have, have the travel I need. The Ford arm pivots almost at the rubber boot opening in the bell housing and pushes towards the rear unlike some Chevy's that pivot on the passenger side and push to the front with alot of travel.

 

Congratulations on the recognition.
18 must be a good one.

 

The mechanical linkage has an inch of travel at the pedal so it takes a lot of frame twist to exceed the free travel at the fork. The issue is the tube binding on the studs as everything twists it just don't turn. This is forcing your master cylinder to take up the slack after the frame and engine twist and now you have vibration issues between the masses.

Also seems like a hydraulic stay cable on the clutch fork would make backing uphill interesting.

Sorry if it is not an answer to your question you want.

 

It doesn't take much to cause issues. On my 69 Dauntless, when the driver's side motor mount went south the clutch shuddered so bad in reverse you couldn't back up a slight incline without putting it in low range. It was hitting some harmonic frequency you just couldn't work around. Fixing the motor mount solved it immediately. If it was a cable clutch or hydraulic clutch mounted to the drivetrain, it wouldn't have been an issue.

All that said, since it's a harmonics/feedback issue made worse by a bad motor mount, your setup will probably never do anything like that. It's really unknown until you try it.

 

Fork ratios are usually around 2:1. 2" of movement at the slave attachment yields 1" at the to bearing. It takes 5/8-3/4" to throw out the average clutch and have to bearing air gap. No much room for slop.
Personally I'd mount the slave off the bell and move the attachment closer in for more adjustment.

 

Thanks for all the input. The Bronco fork is about 2" longer than the Mustang of the same year and use the same bell housing. Bronco Forks were $18.00 and Mustang $180.00 so you know which one I bought. The shorter Mustang fork must be because of limited tunnel space. My original plan was to cut and weld the Bronco fork and mount the salve cyl to a bracket on the bell housing/motor separator plate but when I got the engine sitting in the frame it looked just too easy to build a bracket to mount the slave cyl to the frame. I'm still up in the air. But anything I do will be with torque restained motor mounts that can't sparate.

 

I cannot really say, I found this on wikipedia.
I just want to say that this period was my change in life...
Everyone has his own souvenirs... I was ending my military duty, and starting my 1st life ... then all changed, again. True life. After student life.
These guys with long hair, it was funny but it was like this. It is already deep past, many are already dead, as some of my friends of this time...

Glenn Lewis Frey (/fraɪ/; November 6, 1948 – January 18, 2016) was an American singer, songwriter, actor and founding member of the rock band the Eagles. Frey was the co-lead singer and frontman for the Eagles, roles he came to share with fellow member Don Henley, with whom he wrote most of the Eagles' material. Frey played guitar and keyboards as well as singing lead vocals on songs such as "Take It Easy", "Peaceful Easy Feeling", "Tequila Sunrise", "Already Gone", "James Dean", "Lyin' Eyes", "New Kid in Town", and "Heartache Tonight".

 

Is that a Ford overdrive 4 speed trans? Where did you find that adapter?

 

It's a Rug Muscle car Top loader 4 speed out of a 1968 Mustang 390. the complete adaptation is about 40 years old and has been in storage for over 30 years. I doubt if you could find another one. I replaced all the bearings and seals and small parts in the trans and dana 18.

 

Went for a drive around the nieghborhood.

 

I took some advice and went the more complicated route. Mounting the slave cylinder to the frame would have been quick and easy just an angle bracket but the bell housing mount didn't take all that long I milled off about an inch of webbing on the bell housing sio I coud get to two bolts with flat stock and used a piece of angle to wrap around and pick up a bolt hole on the other side of the block. It turned out to be a bigger uglier piece than the frame mount wold have been but I think in the long run it will be better.

I spent some time on the lathe and made up an adjustable push rod.

 

I had some time the other day and managed to hold this in roughly the spot it will be bolted. I also picked up a length of 1/4" high test chain and a couple of lynchpins for the driveshaft loops. I also have to make a new dash bar. Minor rewiring is needed like a kill switch, battery disconnect, the fuel pump will have its own switch, rear facing light, and of course, I'll be wiring this with the intention of keeping my column mounted key switch. I have to remove a few feet of fuel hose and use fuel line. Started working on a template for the transmission cover.

 

I am cleaning up my spare D20



I ordered this kit TeraFlex 2112020 Low20 Gear Set Kit-Manual for 1963-1979 Jeep CJ-5 2WD/4WD Gas | eBay
I'm gonna build a lower geared tcase. Parts should be here in a week or two.

 

Cool, I was hearing on other sites that TeraFlex had discontinued the low set. Maybe only for the 18?

 

They still make the low 20 set, inventory is a little low but I bought mine maybe a year and a half ago. I think I had to wait a couple weeks for mine to ship from teraflex as they only make them in limited batches. Great upgrade, I recommend doing twin sticks with it and removing the shifter interlock!

 

Already have the twin stick, but I forgot which interlock pill that I removed on the current D20. I do have the capability of 2WD Lo now. There are 2 of them. Does anybody remember which pill to remove to gain the 2 LO position?

 

The one ''between '' the transfer case shift rails, that looks like a capsule about 1/2 inch long. you will need to completely remove either one of the shift rails to acess it.

 

There are 2 capsules (pills) between the shift rails on this unit. Not sure which one to take out.
