cthomp1025 Posted April 20, 2022 Report Share Posted April 20, 2022 I've recently installed a new clutch plate, pressure plate, and throwout bearing in my 49 Plymouth SD. The push rod is adjusted to just before it engages the clutch fork and when I push down the pedal it engages the clutch fork. When I release the pedal though the pedal only comes up about 2 inches and doesn't pop back up. I've attached the return spring to the clutch fork and it looks like it's working normally. Any suggestions to troubleshoot the clutch pedal? The clutch plate that I replaced was about as thick as a vinyl record and all the new parts are from Andy Berbaum.

joecoozie Posted April 20, 2022 Report Share Posted April 20, 2022 SOUNDS LIKE IT COULD BE THE OVER CENTER SPRING https://p15-d24.com/topic/41271-1948-plymouth-clutchover-center-spring-adjustment/ 1 Quote Link to comment Share on other sites More sharing options...
Sniper Posted April 20, 2022 Report Share Posted April 20, 2022 Yes, before we go too far into what if's you need to adjust the clutch properly. The measurement in the service manual is pedal travel. Run thru your service manual's procedure. I deviate from that and set my adjustment up so that with the clutch fully depressed I get about .060" clearance between the disc and pressure plate. BUt, again, that's not the factory method. Double check your work, let's verify that something didn't get reinstalled wrong during the job. You never know. One other thing to consider. I had an issue with my pedal not coming up one day. Nothing in the clutch or trans was touched, just poor pedal return all of a sudden. Turns out the linkages needed lubed and cycled. Then all was well. 1 Quote Link to comment Share on other sites More sharing options...
soth122003 Posted April 21, 2022 Report Share Posted April 21, 2022 (edited) I just replaced my clutch last week. Took about 30 minutes to find out why the rod was adjusted almost to the last few threads for a new clutch. Something else to look out for is wear on the linkage and pin for the adjustment rods. I am getting a new pin made today and am still looking for and adjustment rod. i don't have any pics right now for the pin but this is what the rod looked like. All told the wear added about 7/16 to 1/2" play in the adjustment rod. Sorry about the crude drawing but it shows what the actual pin looked like.

Sam Buchanan Posted April 21, 2022 Report Share Posted April 21, 2022 Looks like it's time to weld up the hole in the rod and redrill it. I've made pins out of bolts that have shanks long enough to cut off the threads. Quote Link to comment Share on other sites More sharing options...
soth122003 Posted April 22, 2022 Report Share Posted April 22, 2022 That's what I was thinking as well. Wield up the hole and re-drill, but I gotta find a wielder. The pin is being made at the machine shop on base. I used a bolt, washers and nuts for temp fix. Joe Lee Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted April 22, 2022 Report Share Posted April 22, 2022 If you have a machine shop on base they should be able to fix the rod eye too. Quote Link to comment Share on other sites More sharing options...
soth122003 Posted April 22, 2022 Report Share Posted April 22, 2022 Probably true Merle, but my friend who knows the machinist to ask for a favor for the pin, does not know any of the wielders and their in a different shop. Joe Lee Quote Link to comment Share on other sites More sharing options...
Booger Posted April 23, 2022 Report Share Posted April 23, 2022 My high school offered metal shop auto shop and wood shop. (Lucky I guess) I took metal shop and turned it into my vocation, and still did 4 year college. Get yourself a 110 welder, youd be amazed of what you can learn and create.

soth122003 Posted April 23, 2022 Report Share Posted April 23, 2022 (edited) Took those in high school myself. Went into the Navy as an electrician then the Air Force as an aircraft/helicopter mech. Retired at 20 and went contracting overseas, paid all my bills off and then retired retired. Now at over 60 with a bad hip, emphazema, PTSD, aeiou stuff and a wore out husk I call a body...., I used to be 10 feet tall and bulletproof now I am 6'7" and water resistant. All that to say I just can't do what I want to anymore, or if I do it will hurt for days. After changing that clutch my shoulders felt like they would fall off and my lower back was black and blue for 3 days from the creeper and the concrete. So while I could buy the wielder and use it one time, I only buy things that I will use on a regular basis. Easier to find some one to do a 5 minute wield than to spend the money i don't have on a one time use item. Getting old sucks and it is not for sissies but as my idle Clint says, "A mans got to know his limitations".

Booger Posted April 26, 2022 Report Share Posted April 26, 2022 John Lee you have good points. Finding a shade tree welder is awesome. But even if you use it once put it on CL. Brother, I dont get on a creeper no 'mo. It make you old! Quote Link to comment Share on other sites More sharing options...
soth122003 Posted April 27, 2022 Report Share Posted April 27, 2022 Hey Booger, It ain't the getting on the creeper that makes you old, its the getting off of it. Joe Lee Quote Link to comment Share on other sites More sharing options...
soth122003 Posted April 28, 2022 Report Share Posted April 28, 2022 (edited) Edited my post to add pics of the pin clevis. The new one the machine shop made for me is the cats meow. Joe Lee Edited April 28, 2022 by soth122003 Quote Link to comment Share on other sites More sharing options...
cthomp1025 Posted May 2, 2022 Author Report Share Posted May 2, 2022 Well it seems it was a little bit of both recommendations. I adjusted the overcenter spring to the 10" clutch plate adjustment. I also had to extend the push rod about 6" with a coupling bolt and threaded rod. Thank y'all for the help! Quote Link to comment Share on other sites More sharing options...
