550 PTO???

[O6'er]

A nieghbor dropped off a oliver 550 in my yard yesterday. He wanted me to take a look at the PTO for him. He said its slipping. I told him I"m kind of a "International Harvester guy"(careful fellas) but I"ll take a look at it for him. I took the inspection plate off the bottom and about a cup of oil came out and it looks to be a over-center type clutch - am I on the right track? The PTO lever moves with no effort - should it snap forward?? Is there a adjustment for it?? All that oil on the mechanism can"t be good either right? This is a split job isn"t it. If the pto clutches need to be replaced can they be done by simply splitting at the main clutch housing? Can someone just give me a idea how the pto cutch is replaced?

This really looks like a nice little tractor. Although we never owned a Oliver,(we had IH"s) a lot of my nieghbors ran Olivers and spoke very highly of them

Well the interesting thing is this: Which edition of the parts book are they selling?

Fun job, but you can adjust pto clutches thru that bottom plate.Turn pto over by hand & find pin that with screwdriver can pull out. turn until you get a good snap over center. 32# two ft. from pivit point. make sure that brass clutch has a good lube line to outside zert.let that pin snap into a notch to lock it.

I just repaired this on my Super 55. It is likely the rear main engine seal that's leaking. You will need to split the tractor. The pto clutch discs are probably too oil soaked to reuse. Korves has new ones. It is an all day job (at least for me) but it's not too bad. Pretty much everything has to come out to get to the leaking seal. I was able to get the seal locally. A parts book would probably be helpful but the repair manual I used walks you right through the process.

Be careful...most of these manuals do not have "breakdowns" in them for assemblies such as PTO Clutch, steering gears, starters, and such.
Yes, they show the assembled part, but that is all.

Exactly, I have two original copies of the parts manual. One is an earlier edition and does not have all of the updates and conversions in the later version.
