Had a problem with the low speed pedal linkage clearing the bendix cover on a car that we were replacing the clutch pedal on. We got the linkage bent to clear the bendix cover and learned that there was a change in the linkage angle for starter cars. I have another friend who has several hog heads and looking at them I noticed that some of them have the low speed shaft in two pieces like the one we were working on. Was the low speed pedal shaft cut back in the day to replace the spring without having to remove the clutch pedal or what?
The longer pedal shafts were in earlier cars where you had to remove the hog's head to change your bands. The shorter shafts allowed the band to pass through without removing the hog's head.
Also, your linkage problem is caused by using a low pedal from a pre-starter car. When starters came into use, the small linkage arm on the bottom of the pedal curved inwards, towards the hog's head, to clear the bendix cover.
Thanks Jerry. Learn something new about these old cars all the time.
