casper50 Posted March 28, 2017 Report Posted March 28, 2017 Was working inside the coupe this morning and pressed the clutch. Went straight to the floor. I am admitting that I know absouletly nothing about clutches/transmissions. Took a short video. Seems to me that the moving part should be pressing on the little arms when the clutch pedal is depressed. Lots of technical terms being used here. Am I correct? If so why would the arms be all the way towards the front of the engine? Quote
plymouthcranbrook Posted March 28, 2017 Report Posted March 28, 2017 Are you pulling the pedal up manually? Does the clutch engage at all? Will the car move or not move at all? Quote
casper50 Posted March 28, 2017 Author Report Posted March 28, 2017 pedal comes back up by the return spring. haven't started the car since last fall as I have a small garage and I'm in ALaska. It's cold outside so that I can't open the door. Quote
knuckleharley Posted March 28, 2017 Report Posted March 28, 2017 Is the return spring still hooked to the clutch release fork that sticks out of the bellhousing and has a threaded rod running to it? Quote
casper50 Posted March 28, 2017 Author Report Posted March 28, 2017 (edited) yes when pedal is in the up position the part that is moving is towards the rear. When depressed it moves forward. Edited March 28, 2017 by casper50 Quote
casper50 Posted March 28, 2017 Author Report Posted March 28, 2017 (edited) or do i not have it adjusted correctly and it should be up against those little arms when the pedal is in the out position? The fork seems to be as far back as it should go when the pedal is depressed. Edited March 28, 2017 by casper50 Quote
knuckleharley Posted March 28, 2017 Report Posted March 28, 2017 What little arms are you talking about,the arms on the pressure plate? The fork holds the throw-out bearing,and it is the throw-out bearing that applies pressure to the pressure plate fingers that causes it "lock" the clutch plate to the flywheel. The throw out bearing is that little round thing hooked to the clutch fork that the transmission input spline runs through,and it moves in and out as you engage or disengage the clutch by pushing the clutch pedal down to the floor,or letting it come back up to the top rest position. You need to make sure there is some free play in your clutch pedal when it is released and at it's highest position. This is all probably confusing because I'm not all that good at explaining stuff. Your best bet is to buy a Motors Auto Repair Manual that covers late 40's cars,and go to the transmission and clutch section. They will have photos there with explanations below the photos to explain the process. Sounds a lot more complex than it really is. BTW,if you ever pull the trans,it is also a good idea to pull the bearing out of the flywheel that the transmission input shaft fits into,and consider replacing that also. Or at least cleaning and checking it. Quote
casper50 Posted March 28, 2017 Author Report Posted March 28, 2017 the throw-out bearing isn't reaching the pp fingers to push on them. the fork hits it's max rearward travel before the TO bearing reaches them. Quote

Then you have a problem. Find out why this is the case,and fix it. Seems like an adjustment problem to me. I repeat,buy a motors auto repair manual that covers late 40's cars,and go to the transmission and clutch secion. Quote
casper50 Posted March 28, 2017 Author Report Posted March 28, 2017 I"ve ordered one. But surely there is someone here that can give me a hint as to what's wrong so that I don't have to wait a week to get the manual and then find out that I need to order a part. Quote
knuckleharley Posted March 28, 2017 Report Posted March 28, 2017 Maybe go to youtube and search for "replacing a clutch"? They all work the same way. Maybe it is just me and my short attention span,but I always understand how something works when I can see it,and you can spend a week explaining it to me and I still won't have a clue what you are talking about unless I can see it.

Niel Hoback Posted March 28, 2017 Report Posted March 28, 2017 The throwout bearing shouldn't touch the pressure plate fingers with the pedal released. That's why there is "pedal free play", which you will read about in your manual. Quote
casper50 Posted March 29, 2017 Author Report Posted March 29, 2017 the problem is it doesn't touch when fully depressed either. Quote
Don Coatney Posted March 29, 2017 Report Posted March 29, 2017 Per the book. This might or might not help. 1 Quote

This just happened to me 2 months ago! It ended up being a defective Pressure Plate in my case. I cannot speak on your behalf, but I hope that you get this resolved soon. Quote
Dartgame Posted March 30, 2017 Report Posted March 30, 2017 adjust the free play to around 1/8 to 3/16" as measured at the end of the fork. if you cannot do this within the threaded rods adjustment range, something is wrong. 1 Quote
casper50 Posted March 30, 2017 Author Report Posted March 30, 2017 seems to work after lots of adjustment. Can't find the over center spring so either it didn't have one when I bought it or it's in the garage somewhere. I'm pretty careful with my parts so I believe I don't have it. Have to find one as the clutch is pretty stiff without it. Thanks everyone for your help. Quote
classiccarjack Posted March 30, 2017 Report Posted March 30, 2017 Wonderful! I am glad you got it dialed in. Quote
