MarcDeSoto Posted February 9, 2021 Report Share Posted February 9, 2021 I'm re-attaching my brake and clutch pedals on my 48 DeSoto now. Does anyone know if you are supposed to unhook the big clutch spring before re-attaching the clutch linkage? Thanls. Quote Link to comment Share on other sites More sharing options...
Conn47D24 Posted February 9, 2021 Report Share Posted February 9, 2021 Marc, there is a procedure for this as I recall. Loosely install one bolt of the big spring bracket. Assembly all other linkages and then swing the spring bracket into place to install 2nd bolt on the frame. The one linkages part that pushes the clutch fork can wait. Back that adjustment off and put it in place last , then adjust. I think that was how I did this. Quote Link to comment Share on other sites More sharing options...

MarcDeSoto Posted February 9, 2021 Author Report Share Posted February 9, 2021 Does anyone know what that pin going through the clutch pedal shaft is for? I installed my shaft on the master cylinder, but I don't recall a pin. Quote Link to comment Share on other sites More sharing options...
Conn47D24 Posted February 9, 2021 Report Share Posted February 9, 2021 I don't recall that either Marc. Quote Link to comment Share on other sites More sharing options...
Sniper Posted February 9, 2021 Report Share Posted February 9, 2021 It's a cotter pin that goes thru a castellated nut (6-50-3) and keeps the nut from backing off of the bolt (9-50-2). Quote Link to comment Share on other sites More sharing options...
MarcDeSoto Posted February 9, 2021 Author Report Share Posted February 9, 2021 (edited) OH, Does that mean that the pin does not go through the shaft that holds the pedals? It looks like there's a hole in the shaft, but I don't remember seeing that. If that's true, why do they show a cotter pin right below that nut and bolt?

Sniper Posted February 10, 2021 Report Share Posted February 10, 2021 We might be talking about two different pins, I was talking about 5-60-1, I think you are talking about 6-43-8, which I did not see. Not sure what it's doing. maybe we need to see the same exploded diagram for the brake pedal parts to sort it out? Quote Link to comment Share on other sites More sharing options...
MarcDeSoto Posted February 10, 2021 Author Report Share Posted February 10, 2021 Ok here are the brakes. Quote Link to comment Share on other sites More sharing options...
Sniper Posted February 10, 2021 Report Share Posted February 10, 2021 Only thing I can think of is that the pin you are referring to is acting as a sort of spacer to keep the levers and/or bushings properly spaced. Quote Link to comment Share on other sites More sharing options...
MarcDeSoto Posted February 10, 2021 Author Report Share Posted February 10, 2021 (edited) yes, that could be! Maybe the pin was already in my shaft, but there is no way the pin could extend outside of the shaft because it's a tight fit in the MC housing.

61spit Posted February 10, 2021 Report Share Posted February 10, 2021 Looks like it (pin 6-43-8) goes through the hole in the master cylinder and through the shaft to hold it centered in place and to keep it from rotating in the master cylinder. Could be that the replacement master cylinder does not have the hole in it. 2 Quote Link to comment Share on other sites More sharing options...
