806 pto issue

Cornbower · May 20, 2014

Last summer we were using the 806 to run the rotary mower and when we would get into some heavy stuff, the motor wouldn't bog, instead got a loud grinding noise from in the belly. Talked to a few local guys and they talked like some teeth would be wore off the main drive in the center section. Well after a long cold winter and finally getting corn in, got it inside and split apart. The gear teeth all apear to be in decent shape. The shaft did seem to have some wobble when the retainer was still installed. I noticed the bearing has a little weld bead on it where it sits in a groove in the retainer, is this possibly someone esles home remedy or was that a factory job. Any other places to check out?

Check your splines on the IPTO shaft, this is the hollow shaft that has the smaller shaft sticking out of it, the splines will wear thin and then will start to bend over. Also check the splines inside clutch pressure plate that the IPTO shaft slides into, they might be worn down to. It could be something inside the pto also, sounds can travel to different areas threw the shaft that runs the pto.

The splines do show a little wear, nothing too terrible tho. On the clutch end it shows minimal wear as well but the rivets holding the hub is loose. I going to pull the Pto off the rear and look at that while I have it in the shop. I assume it has some sort of sleeve coupler in there that it drives off of?

The lower IPTO drives both hydraulic pumps before the PTO assembly so it is fairly easy to tell in what area of the tractor the problem is at. If the PTO slow down but the steering and hydraulics still work the problem is in the PTO unit. If the problem with the PTO also affects the steering then the problem is in the clutch area.
