I just recently got a 1951 Oliver 77 Row Crop
Tractor. The problem: Clutch is dead and I am
trying to get this darn Bell Housing off!!!
Everything went fine until I took the drive shaft
coupler (at the end of bell housing of! (That
wasn't the hard part either, coupler slides nicely
backward and forward... but what I discovered
after I did it) THERE IS A "smaller" SHAFT WITHIN
THE DRIVE SHAFT! How do you get that stupid thing
appart so you can remove the bell housing and all
the clutch guts!! Otherwise I can push the bell
housing only that far, barely past the fly wheel!
Is this a chinese puzzle or do I really need to
pull the engine?!? (I hope not, yiks)

I would be so thankful for any hints!

Uwe

I've got one apart also now, and it's pretty easy. You don't have to pull out the pto all the way out. Just get it past the coupler is all you need. If you go too far it falls out of the hydraulic pump. When you get it pulled back, side the coupler toward the motor as far as it will go and then twist the bell housing sideways. That will give you enough room to take the bolts out of the pressure plate. Pull out the clutch disc and pressure plate tip the bell housing and pull the shaft out of it. Take off the gas tank and lift it out of the top. If you can't get the bell housing to tilt, make sure that the shaft didn't fall out of the clutch disc. Good Luck.

Uwe, yes this setup was done this way for the live hydraulics and live pto. Once you remove the pto you should be in good shape. I have a friend who was working on a newer White (newfangled Oliver) and put it in the back corner of his shop. I don't remember why, but they couldn't move it and it came down to pulling the engine to do something to the crank unexpectedly and you can guess the next step! The patch in the wall still gets a good laugh when someone asks.

To remove the PTO shaft just take off the cover that the lever goes into. There are four 3/8" bolts from underneath that hold that cover on. Then remove three 3/8" bolts that are holding the shaft in place. The clutch assy. and shaft will come out as one unit. Good luck, WB.

Don't panic, this happens to about everyone who is not familiar with the Olivers. This smaller shaft is the PTO shaft. Remove the PTO unit from the tractor. This just involves taking out the 4 bolts that hold this unit to the back of the tractor. This shaft runs from the pto up into the flywheel. This same shaft also powers the hydraulic pump. I personnaly prefer to just pull the engine for this job. Just makes everything easier and just as fast.
