Help! - PTO shaft cover

but if it is.. then there is a roll pin (sometimes a solid pin) that goes through the shaft to hold the ORC onto the tractor PTO shaft. to remove the pin, remove both the grease fitting and the plug (or fitting) on the other side, rotate until you see the pin.. (might be covered with grease) then drive it out with a punch or other driver (a nail)...

If you want to make sure it gets answered, I'd start a new thread...

• John's previous answer..

The looseness is not the PTO shaft, as Jim said it is the OCR. These are available at any store that sells tractor parts (~$50).

BTW: What an OCR does is an important safety function. The PTO shaft is directly connected to the drive gears inside. This is why you loose PTO power when you engage the clutch.

Think about this... If the drive gear runs the PTO, then... The PTO can run the drive gear. Where this is important. When you run a high momentum energy implement (mower) when you engage the clutch you dis-engage the motor from the drive shaft, however you do not disengage the PTO (as they are directly linked) Thus the energy in the spinning mower can an will continue to drive the tractor forward. An obvious hazard if driving near trees, ditches, revines, hillsides, etc.

To ad a note to PTO spline size... Standard spline size today is 1 3/8" origonal splines on Fergusons were 1 1/8" The output on your OCR is likely 1 3/8" you can visually see the dia. difference when held up next to each other (Male ends) Another cause for the looseness if very bad is you have 1 1/8" PTO and a 1 3/8" input side OCR. If this is the case you will need to buy a new OCR of proper dimensions before you mow.

My father was brush-hogging some outerlying areas of our farm when it came to dinnertime. He parked the tractor near the driveway and with the PTO engaged and the brush-hog still spinning (slightly elevated), jumped off. That's all it took. The brush-hog (now directly connected to the wheels) propelled the tractor down across the driveway, past the greenhouse, through the garden and (just before it broke over to the seriously steep stuff) it caught on two small pine trees on the fenceline. The trees looked to small to hold much of anything, much less a Massey 135, but they gave just enough to arrest the tractor. I am sure it had something to do with the fact that there were two and they were flexible (kinda the smae theory as those laminated scaffold boards). It was a sight seeing that tractor standing up on it's rears leaning on that brushhog. The important thing here was no one was hurt. Subpoints are that we all learned a valuable lesson while no major equipment was destroyed. It was during the Reagan years and we did not have a pot or a window, so it very likely would have put us out of business.

Several years later, my stepfather (a wonderful man) performed exactly the same stunt in the same location. The only difference was the brand new Chevy truck that was parked in the drive (Clinton Years). Good thing it was there, that tractor may have never stopped.....

Equipment operatiojn has a steep learning curve. And some lessons are just expensive.....

What it sounds like to me is that the ORC bearings are worn out. It will just get worse... You could take it off and rebuild it and still have a used part, or for about $50 you can get a new one... be sure to check shaft sizes because the ORC comes in 3 flavors... 1-1/8" to 1-1/8", 1-1/8" to 1-3/8", and 1-3/8 to 1-3/8"... If you have an original type PTO, it will probalby be the middle one... And unless you PTO shaft is dripping oil at the tractor, I'd leave that alone for now... JIm
