Let's see if any of y'all out there can help me with this. I'm working on one of my '46's and need to rebuild the brake/clutch pedal assembly. Does anybody know how to get the pedals off the shaft so I can replace the pedal bushings? I know it can be done, I just don't want to screw anything up by doing it wrong.
[updated:LAST EDITED ON 29-Jan-02 AT 05:02 PM (EST)]Sorry I didn't see this earlier, what I did was heat the assembly in an oven at 250 or so for an hour, coat everything with some parrafin (wax) and it all slid apart. The cast parts expanded more than the solid forged parts.
Thanks Jalopy, I'll give that a try as soon as the wife is out of the house for a while. I'm not gonna try explaining to her why I have truck parts baking in the oven
Looking for any updates/ feedback on this suggested procedure.
Have enough play in both my pedals that I'm willing tackle re-bushing them. Already have the assembly out, tried some moderate pin driving but nothing budged.
Then the follow up question; would I re-heat the assembly to reinstall the pins?
Also thinking only one side needs to come off the pivot rod- the short arm to work the clutch, then the rod can exit to the left, thru the bracket & the brake pedal.

I drove the pin out of the brake pedal bracket. Heating the assembly may help. Maybe the bracket, bushing and shaft expand at different rates to make this easier.
Then buy new bushings and a shaft if it is worn.
I'm working on mine right now. No heat required, simply drive out the shaft retaining pin. The pin will have been peened to lock it in place. You will need to either grind the peened end off and drive it out or file around the end to remove the expanded part, then drive it out. I filed mine so I could reuse the pin. The bushings are the split type and press out easily. If the shaft has slight wear on one side, (most wear is to the rearward side), it can be rotated opposite from it's original position in the bracket and reused.
Brake and clutch bushings are the same @ 1.78" long x .885" ID x .951" OD, at least on the '46 half ton anyway.
Hope this helps.
Hmmm, I have the 2-ton COE, which in '49 is an 'F-6'. Almost always ignored in the catalogs.
Here's my assembly :
How different is this from the non-COEs?
I cleaned really well around the pins & took off my spectacles, but I wasn't sure which end was the head of the pin/peened over. Tried the short clutch arm at 12 o'clock in the pic. Nervous about cracking the bracket if I have to wail on it.
It looks liked the peened end of the pin, in the pic. Support the lever arm so that you are not putting force on the bracket then tap the pin out of there.
Ground the peened end off, heated it a bit with a torch and drove the pin out.
There is a continuous bushing the width of the bracket and it has some noticeable wear. Also did not realize that the bolt seen in the upper ear on the bracket in the above pic was to retain the bearing- the parting line in the casting made it appear to be some sort of clamping/load feature. I had the bolt very loose but still there, so when I drove the bushing out, it got minority deformed at that end.
C&G Ford doesn't show anything like the bushing the COE has (which, BTW, is a fascinating piece of engineering by itself)… I will get some pics up in a bit but am I stuck reusing the old bushing??
