Overcenter Spring Adjustment????

[55 Fargo]

Hi all,got the clutch rods and over center spring, a new used turnbuckle rod, a new used torque tube. All is well, the trans is not in yet, so I will need to install it before the final adjsutments are made.

Because the over center spring was off, the turnbuckle rod was replaced, how and by what spec do i adjust the overcenter spring. Now I don't have the special Miller tool to use as a gauge, I have seen the pics of the spring being adjusted, have a Chrysler shop manual showing it.

Unfortunately, When I re-cut my throw out fork rod to spec, it is now about 1 inch to short, so I will be using a rod from a 1950, which is okay, but not exactly the same. I did cut the rod to 6 and 1/16 of an inch as per DonC. pic, but the location of the throw out fork, in relation to position, must still be a little further back, than a stock 46 to 48 Plymouth, not sure why. The belll housing, engine and trans are from a 1951 dodge, could be a little different in size I suppose, but not convinced. So I will use the other rod for now.

I am going to make guide pins to install the trans, what gasket sealant is best used on the trans to bellhousing gasket, I was going to use a thin layer of Permatex, on the trans side of the gasket, right or wrong.

Thanx everyone who have helped answer the questions on this big job, from beginning to end..........Fred

Adjust the turnbuckle so that the pedal pulls hard down/ hard up at one inch from the top of the pedal stroke. I used my son to work the pedal while I worked the wrenches. The Spring helps reduce clutch pedal force. It reduces the force required to release the clutch. You do not need a special tool. Bob

I agree with Bob V. No special tool required. Trial and error worked for me.

Is the '51 dodge bell housing the same as the '51 Plymouth? I have '51 Plymouth engine in my P-15. I tried to use the '51 bell housing but it didn't have the holes to mount the clutch linkage flexable mount plate. I reused the P-15 housing. Don't be discouraged while getting the linkage to work right. It took me several days of messing with it to get it right. Good luck!!

Hi Bob, your right, the 2 holes are missing from the bell housing for the plate, that attaches to the clutch torque shaft. But I did mod this, with a bracket that attaches to the bottom of the bell housing and it works fine, the clutch torque shaft is in a correct position.The throw out fork position,or it's opening may be different, have nothing to compare it with. I will take a pic today and post it to show you or anyone else that may be interested........Fred

Any idea, where the brake pedal retrun spring attaches to. know the obvious point on the brake pedal shaft near the MC, but where does it attach after that..........Fred
