2-135 Clutch

Putting a clutch in the White. Earlier serial number tractors used a 6 lever type pressure plate. Seems there are three pressure plates that were used.
All seem to interchange what Ive learned?? These clutches push quite hard. Is there any advantage a 6 lever verse a three lever? Probably
squeezing the same number of springs, but is one type pressure plate made with more mechanical advantage? Wondering what is your experience?

Thanks

Ok I'm an agpartsltd dealer, and looked them up. I used to know the differences but forget some now. They actually list 4 different clutches, and they all interchange. They list a 3 lever with 15 springs, a 6 lever with 18 springs, a 3 lever with 18 springs, and a 3 lever "heavy duty" with 21 springs. Now obviously the one with 21 springs is probably going to be a hard pedal to push, and the once with 15 springs is probably going to be the easiest. Now in the agco parts books, they only show the 3 lever 21 spring, and 6 lever 18 spring in the earlier book and the 6 lever 18 spring being earlier serial number, and the 3 lever 21 spring being later serial number. Then for the series 3 the 3 lever 21 spring is the earlier range, and the 3 lever 15 spring is the later serial number. Now they all sub to the same clutch through agco, which is a 3 lever 15 spring clutch. (are you confused yet...) Really, just because there are more or less springs, doesn't mean that a clutch is easier, or harder to push though because spring rate has a lot to do with it too. Ok, before I hit send, I called someone who worked on these when they were new(and a long time after) and he said that except for the heavy clutch, all of them have the same release pressure. I'll try to get a picture of what I did to help my 2-135, but its over at my moms yet. I extended the clutch throwout lever, just so it clears the fuel tank. It may not be much, but it made a huge difference when round baling on my left leg... Sorry for not really getting you a great answer, but it is what I found. Although, I would assume that the newest pressure plate which is the 30-3412547, except for the 72161849 that they sub to for the 140-145 tractors that I don't see aftermarket for

Found the picture I took several years ago when I made the extension.

I'm not sure if the issue is the pressure plate or the coil spring up under the dash. There's a rod that sticks straight up and has a compression spring on it. The rod hooks to the clutch pedal. I took the pedal out of mine one time to put a new bushing in it and I had a devil of a time getting it back in there because that spring has so darned much pressure. Unhook the rod from the lever on the bell housing and I think you'll be surprised how hard the pedal pushes with nothing hooked to it.

I wondered about that spring myself, just have never taken the dash back apart to get to it. I kinda understand why they have a spring there, to keep the pedal from rattling around, but it doesn't need to be quite that strong I wouldn't think...

I was looking up other parts for my equipment today, and started researching some of the clutch linkage stuff. It confused me when you said compression spring, because I knew mine had an extension spring... The first ones had an extension spring, and the series 3 and newer tractors have a compression spring. Another thing I found was the bell cranks, at serial number 292563 they changed the part number, so I'm wondering if they adjusted the ratio to make it easier to push also. They did change the throwout shaft and fork at the same time, but I think that was only because they made it bigger, 7/8 to 1 1/4". I think I heard some of the early ones breaking, but don't hold me to that at all. I might call tomorrow and give them the part number for the newer serial number bell crank to see if it's still available, and if so how much that I might try it.

I thought about that after I posted, that mine's a Series 3 and the earlier one with a different dash might not use the compression
spring. Is yours a Series 3 then?

Mine is a early one with the different dash. It uses an extension spring instead of a compression spring like yours. It also uses a completely different bell crank from yours.
