3-Point Hitch PTO worn out??

[JC-jetro]

Larry, I think JC is talking about the internal shifter fork and sliding shaft as shown in the attachment. Item #11 attaches to the external PTO lever linkage. As it rotates left-right in the slot on the shaft, it moves the shaft ,#15, and the PTO shifter fork, #16. That shaft has a detent ball (#9, 10, 20 I think) and a PTO engage switch , #26, 27, & 28, that drop into the shaft indents. If Nathan's PTO engage light is illuminated, then that's another sign that the shaft is in the fully engaged position. If the light is not illuminated, it would indicate that he needs to adjust the linkage and get the gears more fully engaged.

yes Jim, That's what I was referring to. items 10,9,20 and 24. At the least I'd take a look to see if the ball is nice and round and spring is not busted. I could not find info in actual length of spring for comparison sake.

JC,

Not really a spring and ball detent on these JC, just a little notch at both ends of the slot in the fender.

I think the other Larry probably has the right track. I would disconnect the linkage and see the extent of travel. I know mine was very difficult to move in the beginning and there was a lot of flex with very little pressure, it seemed like it could be bent easily. Lots of spray lube on the shaft holding the shift levers really helped. There is no zirk here which surprises me.

larry,

If you take nut #24 on Jim's diagram leads you to internal ball and spring of the detent mechanism.

JC,

Well it seems I've had a misconseption about the difference between the 33 and the 29. For some reason I thought they were almost the same except for horse power. It appears they are not even close in the tranny area. :ashamed:

Larry, those are the external levers. The TC29DA is exactly the same as that. I just posted the internal shifter fork that the external lever attaches to so I could show the slide and indents. You saved me the trouble of posting that external lever picture. I believe #17, 18,19,and 20 are the lever parts for the PTO.

When I removed PTO safety switch item #38 fluid pushed out pin item #36. Which end of pin rounded or flat works against the switch?

I believe the flat end works against the switch and the ball end goes into the transmission. It only has to push the switch in/out. The rounded end rides on the range shift shaft and drops into indents when not in neutral. You should be able to look at the ball end and see some wear indicating it has been side loaded by the indented range shift shaft. Put the assembly back together and then hook up an ohmeter to the two wires. You should see continuity and open as you move the range lever. That indicates all is working properly. You can also hook an ohmeter to the wires and depress the ball in the switch directly with the switch removed from the transmission.
