I'm putting the 550 back together. I was looking at the pictures in the IT manual as I was reading about the PTO assembly and I noticed in one picture for the clutch that it had a return spring within the housing. 

I didn't have in mine, nor do I have the tabs that they attach to at the bolt end. I think I can get the springs and make the tabs from flat steel. I'm just curious if anyone has a 55 or 550 apart and could measure one of the tabs to save me the time of trail and error fabrication for the right length to give the proper spring tension.

For giggles I put the pressure plate on the shaft and pushed everything back where it would be if there were springs pulling things rearward. The clutch pedal was vertical. Might explain why there was all that thread showing on the adjustment screw...

After the transmission &quot;job&quot; the previous owner did on this poor ole 550, I shouldn't be surprised to find stuff missing... and I know where all his trans oil went and why. I replaced all the seals except one. Its buried in front of a bearing within the shaft that the pressure plate rides on. I don't have a puller to get at it.
