anyone have a pic of what the linkage looks like on the diff-lock on a 79 580c?....mine is missin'....i think?.....anyway it doesn't work...is the button on the floor by the steer brake pedals it? thanks
I will try to upload a picture of the difflock linkage it it will go. The difflock should be a metal disc on the right side coming up through the floor. The switch kind of under the brake pedals is the declutch switch for the shuttle.
The small steel button on the left side of the cab floor is the clutch cut out switch. Never have seen any of them work, usually rusted, seized or the wires corroded off. The diff lock is on the right side of the floor. If the diff lock is not working could be a few reasons, roll pins sheared off the shaft, seized linkage or possibly the collar has been removed. I have seen the collars removed from machines used in a fleet, keep operators from stomping on the diff lock while the wheels were spinning at full throttle. Usually good for taking out a side gear...maybe more.
ok from what i seein' in your pic's mine doesn't have any of the linkage.....there is just a hole on in the floor board on the right side by the throttle peddle.....i would have thought it would be on the left side.....anyone know where i could get the linkage setup for it? thanks for the reply's
If you are half handy with a welder you might be able to make the rod(#39) that comes up through the floor. Make the yoke with a couple of pieces of flat bar and then drill for the pin. Use 3/8" or 7/16" rod for the rest. Weld a big flat washer on top to push on with your foot. At least you will be able to see if it works. Phil
i might be a quarter handy....lol......i'll see what i can do about buildin' some linkage.....was thinkin' for a test to see if it works runnin' a piece of wire down there so i can give it a pull and see if it locks..... thanks for the suggestion Phil..
I thought arm #14 in post #3 had to turn down to lock, maybe I got that all wrong. Phil
ok i see what you mean.....i'll have to rethink how to run the wire.....i'm going to test it some how before i build the linkage....thanks for brein' that to my attention Phil....
