PTO shaft

[bones66]

Hearing a clicking noise coming from my Bush Hog as I am shutting down and the blade rotation slowing I thought maybe I had a u-joint going out. However it appears the slip joint is loose. How are they measured to tell if they are worn to the point of replacement.

Grab it in the middle pull it and see how much it moves...........

Got some 澱ack and forth in it. That痴 what clicking as the shaft rotates you can see and obvious fall at the jct. area. Should it not have any, or how is too much measured.

Should be very little play , Maybe a bad u joint making the clicking noise........

I should have been a little more detailed with the clicking. As I shut the PTO and tractor off and bring tractor to a stop the BH continues to rotate for quiet a while. This is when I notice the clicking and the deflection in the shaft as it rotates. Not to say I couldn稚 have a u-joint needing replacement the noise I知 hearing directly corresponds in time to that square shaft rotation and deflection.

The pto shaft could just be worn out where the two half's meet......Are the yoke on the shaft lined up with each other?........

There should be NO movement in a slip clutch. They should be under some pretty high spring tension. Are you sure you don't have a shear bolt system? I'm not sure but doesn't the BH use a shear bolt through two disks? Maybe the bolt is loose. Post a photo.

Had the same noise once, turned out the blades were hitting a bent spot on the deck .You only heard it when it was slowing down.

Following up on 3gunr be sure the blade bolts are tight.
