47 Commodore Brake & Clutch Pedals

Removed the brake and clutch pedal assembly from my 47 Commodore today for a cleaning and painting. I would like to completely disassemble the pedals from the assembly. It appears that the clutch pedal is held to the brake/clutch shaft with a pin that is peened over to retain it. Can I drift out this pin to facilitate disassembly for cleaning or should I leave it alone and clean the best as I can without a complete disassembly?

    I can't answer that question but, if you have the assembly out, and the shaft is loose within its bushings, you might want to take the opportunity to install new bushings. Those pedals get kind of 'loose' with use! I was once told that the bushing can be replaced with a Delco starter motor center support plate bushing from a truck, 1960's and up models. Of course, I neglected to write down WHICH truck, LOL! -- It might have been an International or a Mack.



    Does anyone have that interchange handy?

    Hey Birdie, I'm there right now on my 40 coupe. That is supposed to be a taper pin unless someone has butchered it and replaced it with something else. One end is smaller than the other. The procedure to remove it is to whale (defined in 'How to talk Yankee' as "to strike sharply") on the small end with a punch and hammer. If somebody has peined it over, you'll lilely have to grind the peined part off flush, then whale it. What holds it in, is what's called in the tool business as a 'locking taper', which appears also in the clutch shaft, and rear axles.



    If the wear is acceptable to you, just pump grease in the berzerk fitting until the new grease replaces the old, and starts squirting out.

    Thanks Josh. Thought it might be a taper pin and yes it appears that both ends have been peened over. Do you happen to know which end of the pin is the small end? i.e. is the small end on the bottom or top of the shaft. Really want to do a complete disassembly even though there does not appear to be excessive wear. Just want to ensure everything is completely cleaned so that I can bead blast all parts prior to paint and reassembly.

    The bottom of mine measures 1/4 and the top 5/16 as it would be mounted in the car so it would have to come up thru the shaft.

    Thanks Josh. Will strip it down this weekend. By grinding off the peening I will surely slightly shorten the pin so when I reassemble it what would be the best way to ensure the taper pin doesn't work loose as there will probably not be enough length to allow it to be re-peened. Would it be acceptable to tack weld the pin or should I just go with Loctite?

    Just whale it in tight. It's a locking taper and not s'posed to be peined over.
