Brake & clutch linkage....yuck

[Bretto]

The design is horrible. Lots of joints and who designs an anchor point to attach to a moving part (transfer case). No replaceable bushing on the brake arm? I'm almost going to have to replace everything. This is on my M38.

YEP I DONT THINK THEY FIGGERED ANY OF THESE
RIGS WOULD STILL BE AROUND 60 YRS LATER. THE GOOD
NEWS IS THAT QUALITY REPLACEMENT PARTS ARE AVAILABLE.
BTW, BRETTO-THE TEMPS HAVE BEEN BRUTAL UP HERE ON THE
SNAKE RIVER PLAIN LATELY- DO I NEED TO WORRY ABOUT MY
ELECTROLYC FLUID FREEZING?? IM GONNA TRY IT THIS WKEND.

Now that you say that, hats off to them. I dont think I'll be seeing any cars of today with all their plastics around in 60 years.

Im not sure of the freezing temp of the solution would be. I imagine it to be somewhat lowered with the cleaning soda in there. Im not sure of the physics of having an electric current thru it, if that lowers it as well? Also there is some movement of the solution by the bubbling and with the head of rusty foam, that can insulate it a bit to.

I HAD TO REPLACE MY COMPLETE LINKAGE DURING MY REBUILD TOO.
I THOUGHT ABOUT BUSHING SOME AREAS OF THE NEW PARTS BUT
FIGGERED WITH THE USE ITS GONNA GET WHILE RETIRED THE PARTS
WILL LAST LONG JUST AS DESIGNED . NOW IF IT WAS GONNA BE CHECKED OUT OF THE MOTOR POOL BY A COUPLE OF 19 -20 YR OLD
GIs ..WELL, YOU KNOW..

I too decided to replace all of my linkages due to wear....but I don't think I'd go so far as to call it a yuck design. In fact, seems pretty insightful to me given the parameters under which the vehicle was to be used...rugged...dependable....easy to maintain...with a minimum of parts. Three bolts and three cotter keys and you've dropped the clutch/brake crossshaft assembly....two more bolts and you can remove the clutch linkage crossshaft....from here any renewable parts can be accessed and replaced as necessary. Here's a pic of how badly worn my crossshaft and bracket were....

I figured while I had the tub off and the frame nekkid I'd do everything up right and fortunately these parts aren't too unreasonable. I even got bushing for the old crossshaft bracket so it could go on the part bench as a workable spare.

Jim, let me know where you got the bushings. I could use some too.

I'm going to have to go back thru my paperwork to find out exactly where I got the bushings.....I do remember they were NOS cause they came packaged in a little waxed or oiled cardboard tub that had metal caps on both ends. Hopefully I'll get to look this up tonight....

thanks Jim, No hurry. I have a a bracket that I changed out for a new one during restoration, I kept the old one just cause I hate to throw it away. So putting new bushings in it would be a good idea for a spare which I may never need but someone else may down the line.

I think its either an addiction....or sumptin they put in my genes.....cause I'm still finding "odd" things on the tractor bench in the wagonshed that I have no idea what they are....much less what kind of tractor they went on. So just to be fair to my heirs.....and knowing how much fun I have with "digging" thru things.....I'm piling up all my spares with the same amount of zeal as my ancestors. And anybody who says this is a throw away society has never paid a visit to our barn.....I'm almost certain.....that if we were related.....I'd still have the stick Noah used to measure those cubits on the ark!

I reamed out the brake arm where it pivits and had my son turn a brass bushing for it on his lathe. I pushed in in with my press and reamed it to fit the cross shaft. Now it will last longer. It turns on the cross shaft, while the clutch arm rotates the whole shaft. I also took 5/16 rod, threaded both ends and put clevis ends with pins on the clutch rod. Those silly 90 degree bent ends are a joke. So far, so good! John

I got the bushings from Brent Mullins Jeep Parts in College Station. Part number is 801664 and the cost was $5.00 per bushing back in May of 2009. Wish now I hadn't gone back and looked this up......I'm beginning to wonder if I'm ever going to get done with this thing???

Hey....I like the idea of the threaded rod with clevis ends and pins....I bet it does work better....and its gotta last longer....thanks for the idea.
