I have an Oliver 55 which the fromt sway bar ball joint took out the PTO linkage rod. When this happened, the pivot arm was jammed forward and allowed the spider asm to push forward. This was all during load. From what I can gather, the set screw which secures the clutch plates asm came loose and the clutch plates came out of the bell housing. Again this was all while under load. I have re-aligned the clutch plates and pushed tehm back into the bell housing, but am concerned with the plates floating very free over the shaft. should they be keyed and secure to the shaft ofr did this get desroyed while running? Did the shaft coming loose cause the rear o-ring seal to disengage which would allow rear lube to escape through the PTO drive shaft (which is happening)? Can I resecure the o-ring via the rear by removing the bearing or do I have to do this from the from access? (requires splitting the tractor which I am avoiding) Any and all help would be appriciated. I have used tractors all my life, but have not serviced any to this level. Mostly just PM spring and fall. | ||

Actually, I would split the tractor and check out the damage. The seals would definately command my attention. Splitting the tractor is not that hard. Having the manual would be a great help. They are pricey and can be purchased at Floyyd County Historical Society, http://www.olivertractormanuals.org/, but you can buy a CD version on ebay. | ||

Thanks. The tractor came with a shop manual. Which has helped already. The problem for me is that I am not seeing what keeps the PTO clutch plates or the spide assembly from, moving out of the bell housing. Any Ideas? Or will this make sense after I split the tractor? | ||

Not sure what you mean, but the discs are held in by a lock ring. I'll have to go out to the shop tomorrow and look at the parts book and try to see what you mean. | ||

If you have a manual, you will see the actuating fork that would keep anything from sliding forward. Like I said before the discs themselves are held in the hub spider by a lock ring, it's the one with the spring loaded pin you push down to adjust your pto. If you have any questions, email me. I am denfinately no expert, but I have my Super 55 apart and I am in the process of reassembling it. | ||

I was just out there trying to see what moves. The whole clutch assembly moves forward (with the shaft) when I push the lever to dis-engage. I cannot see what stops the shaft from moving foreward in the manual. | ||

I think I know what your problem is. The splines on the take-off shaft are not lined up with the splines in the clutch hub. Remove the hub and see if you can get them lined up. Also there is a double set screw on the hub assembly that needs to be lined up with the grove on the drive shaft. If you have the manual look on page10-261, section 3, second paragraph. | ||

I finally got this project going. Split the tractor and was able to find what I think was the problem. The PTO drive shaft pulls forward about 6 inches. I removed the rear seal and bearing which allowed me to pull the coupler out. There should be a roll pin keeping the coupler to the drive shaft. I suspect that when the sway par hit the linkage, the roll pin was sheared. This would acount for the rear leaking oil. the o-ring is pulled from the shaft as well. |
